Social Networking has become a household name ever since the massive popularity of the famous social networking sites like YouTube, MySpace, Friendster and other similar sites have made waves in the Internet arena. Social networking, since then has been potentially seen as a growing avenue by business people where they can market and publicize their companies along with the products that they are promoting. Looking into this perspective, I have enlisted some of the ways below on how one can effectively use social networking as an avenue to market and advertise a service or a product.
• If you are a registered member of a social networking site, like MySpace, you are actually being given the privilege to come up with your own, personal site. With this, you can incorporate some advertising materials on your own site and promote it from there. Since you are a on a social networked site, people who see your site with similar interest are your easily captured potential clients. Thus, enabling you to instantly have a client of your own.
• With social networking site, it is easy to capture potential clients because of the capability of the site to invite other people to form part in any specific group. This is a feature seen by most business people as a potential means to massively promote any service or product using the social networking site.
• One of the best ways for anyone who wish to use social networking as a means to advertise is to invite and invite more people to “network” with his account. This is a quick way to allow more possible traffic on any one’s site.

Targeted Social Networking - 4 Keys to Get Started With Social Networking
Today the concept of social networking provides a great medium for people to meet others both physically and virtually. The first step in social networking lies in choosing the social networking site depending on your needs. if you need to physically meet people, use a social network with direct communication and location data. If you want to meet people virtually, use a site with people having similar interests to you and one that permits people to search for these interests.
You can succeed in social networking only if you ensure you are using a safe networking site as there are many cases of identity theft, personal information disclosure and cyber stalking in many social networking sites.
You have to place information on the social networking sites to get people sharing similar interests to meet each other. This means that it is important that you provide only honest information about yourself. Many people lie on the network, and get people fooled into relationships. There is no point in changing your particulars in the hope of getting more acquaintances, just because you are dull and boring. This only leads to mistrust between you and the acquaintances once they find out you were lying.
You can also use social networking sites to get business oriented connections by choosing a community or group that is relevant to you. then you inform the people here about yourself, your business and the expertise and services you offer. you are sure to get new business contacts by participating in these discussions.
Then again, getting referrals from the members of the social networking sites also help as these referrals create an impression of you being an authority of a particular field. They refer their friends to you if and when they need services or products that you offer.

Guide to purchasing a Diesel Generator
There are many grades of durability of diesel generators on the market. You will find that the larger the machine the more well built it is to withstand the pressures of use. This is the general concept when it comes to the diesel generator that the larger the generator the better it is designed.
It is essential when considering purchasing a diesel generator that you are sure of what kind of use you will be demanding. It is very common for the diesel generators that are larger to be installed on ships as backups during power failures. There are often systems on ships that use power systems that are related to weather. This is not reliable and as such a diesel generator is a good choice. It is better to opt for the larger models as these are very well designed to handle the load.
Many businesses seeking to protect their sensitive computer networks can also depend on the diesel generator. These are excellent sources of power should the power fail. This is also great for medical equipment such as those that are essential in hospitals and can provide performance that is low maintenance.
When deciding which diesel generator to choose it is important that a list is constructed of the various pieces of equipment that will be using the generator power. This will aid in the determination of the total wattage requirements and therefore determine which capacity of generator will be required.
One of the first points when comparing diesel generators is to determine the wattage requirement and compare this to the price of the particular generator. This is essential as it is important not to overload the system and this will determine the best generator to suit your needs. It is also possible for persons with intermittent generator usage to opt for the diesel generator due to all the perks such as reduced fuel costs and maintenance costs.
It is also advisable that when you purchase your generator that you install it with a transfer switch. This may require a qualified electrician. It is also essential that the generator you choose will have adequate storage as this is important in maintaining the right temperature. You may also need other features such as soundproof enclosures depending on your space limitations as the diesel generator can be quite noisy and is best installed away from homes.
Other features that will be needed for your generator include shutdown systems. There are three major shutdown systems available. These are low oil pressure automatic shutdown kits, over-speed shutdown kits and high temperature shutdown kits. These are all necessary for the protection of any diesel generator that you purchase.
Make sure that the diesel generator you choose is run at a low rpm approximately 1800 rpm to ensure long life. It is better to opt for a generator that is the best in terms of fuel efficiency and if you can opt for a brand name. They may be a bit more expensive but they will tend to have better warranties than the other generic brands on the market.

Diesel Generators Explained
A diesel generator is composed of a diesel engine and an alternator or an electrical generator, which converts the power created by the engine (expressed in RPM, revolutions per minute) into the required voltage for homes, industry and remote work sites. The need for power for homes and sites, which are not connected, to a power grid is a growing need throughout the world. Remote areas of Central and South America are no longer too poor to afford electrical power but not at the stage to built vast hydroelectric projects or large power grids.
They can afford to build local village electrical power plants, which can meet the modern needs of the people until the modern power grid can reach out to them. There are places in the United States that are developing ahead of the ability of the local power company to expand; other places throughout the world are at the edge of civilization. All of these require power for business, commerce, medical treatment facilities and communication. The price of the modern diesel generator, the new technology incorporated into these units and their availability throughout the world make them an immediate solution.
Homes and ranches, villages and towns and remote sites should create a power needs list that includes every appliance in the home, business, school and public facility in order to determine the wattage needed. After this the home or ranch owner, city engineer or site foreman can select the proper sized diesel generator. Every diesel generator is rated at how many kilowatts of power it produces. If the home or ranch requires 22 kW to 25 kW then the sized generator should be at least a 30kW. A brigade sized army unit twenty years ago used a diesel generator(s) rated at 90 kW but its’ needs were lighting and mess hall refrigeration. Today it could be quite a bit more considering the new technology.
When you decide to provide power through diesel generators then you should consider whether you need a backup. The power of the generator is rated at 50% engine speed. The 30 kW diesel generator actually operates safely at 25 kW at 1800 rpm for prolonged periods of time. It would be safer if the home or ranch had two generators scheduled to operate in an alternating schedule of 12 hours each. This would ensure that the proper maintenance and care could be given the generators while providing continuous power. Other considerations in selecting a power generator involve selecting one that is a four-cycle, water-cooled industrial diesel generator.
A water-cooled generator operates more quietly than an air-cooled and it lasts longer. There are two electrical systems involved with a diesel generator, the DC (direct current) and the AC (alternating current) systems. The recommended DC system should have a starter motor with a battery-charging alternator with a solid-state voltage regulator. It should have an engine pre-heat electric switch and start/stop switch.
It should have an emergency engine shutdown system to protect the engine in case of oil pressure loss, excessive generator speed, over cranking and engine high water temperature. Finally, it should have DC electric system breakers. Make sure that the AC system is a four-pole revolving field and is has an AVR (automatic voltage regulator). These generators will provide power that is within -+2% as compared to utility company variation, which is -+5%.

Portable Generators
Portable generators are used in homes and in places where there is no power or the need for power is minimum. Portable generators are generally smaller and are designed to use for a few. A portable generator of 5KW has enough power to keep lights, refrigerators, computers and televisions running for 7 to 8 hours. Portable generators are normally powered by gasoline, diesel, propane or natural gas. They are the most popular of all portable generators. Gasoline generators are relatively less expensive but require frequent maintenance and have a shorter life span. Gasoline has a short shelf life and cannot be stored for a long time unless treated with stabilizers.
Diesel generators, on the other hand, are fuel-efficient, consume less fuel per kilowatt of power produced, have longer life and require less maintenance. Diesel can be stored for longer periods of time. However, they are harder to start in cold weather and noisy. Portable generators powered by natural gas or propane is the best choice if available. The generator lasts longer and burns cleaner.
Before choosing a portable generator, the total wattage of all appliances to be powered by the generator must be calculated. This includes the starting wattage required by appliances with motors, such as refrigerators and freezers that use two or three times their normal wattage power to start. The generator should not only meet the normal wattage, but the start up wattage of the appliances. Moreover, the generator must have the necessary voltage ratings to run electric appliances such as the ovens and clothes driers that are rated at 240 volts. A portable generator should have at least two receptacles of 120 volt each. Generators that provide a longer runtime per tank of fuel or having a fuel tank capacity of around 5 gallon of fuel are preferred especially, by people living in areas where power failures are quite frequent.
A portable 7KW generator that can power lights, furnaces, sump pumps, televisions and refrigerators may cost $1000 or more depending upon the quality and the type of generator. For a normal home, an ideal generator would be in 10KW to 12 KW costing around $2700 for 10KW and $3700 for a 12 KW. Portable diesel generators are available for use on construction sites in the range of 200KW and more.
Before operating the generator, read and follow the instructions given in the owner’s manual. Observe the operating and the maintenance procedures strictly for safe and trouble free operation. Avoid putting loads on the generator that exceed the manufacturer’s rating. Also, do not run too many devices at the same time. This trips the generators circuit breakers causing loss of power. The generator must be operated at least twice a year with full load to keep it in working condition. Keep the generator outside the house but never in a garage or in a basement. Carbon monoxide emitted from the generator can be hazardous to health. Use only the recommended extension cords for the generator. Hire the service of a qualified electrician to install a transfer switch if the generator is to be connected to home wiring. Do not refuel the generator when it is under operation. Spilling of fuel may cause fire. The generator should be kept dry and should not be run in wet conditions.

Diesel Generators
Fuels such as gasoline, diesel, propane or natural gas basically power home generators. Some models also have multi fuel capabilities and run on gasoline, propane or natural gas. The choice of the fuel will depend on the availability of the fuel in times of emergency, fuel consumed per kilowatt of power produced, maintenance of the generator and the comparative risk of storing the fuels.
Diesel generators consume comparatively less fuel per kilowatt of electricity produced and more fuel-efficient than generators powered by natural gas or gasoline. For every gallon of fuel consumed, diesel generators run 2 or 3 times longer than gasoline engines. Diesel generators do not require frequent maintenance, as is the case with gasoline generators and are designed to run continuously for long hours. Most generators come with a water-cooled engine with a speed of 1800rpm. This ensures the engines durability, and at the same time, makes it the most dependable of all the other types of generators.
Unlike gasoline generators, diesel engines are safe as they work on the principle of direct injection and have no spark plugs, which keep them relatively safe from potential fire. Diesel has a longer shelf life, and being the least flammable source of fuel, can be stored for more than a year.
Diesel is available at most of gas stations and can be conveniently carried in cans. However, diesel generators are hard to start in cold weather; emit more smoke and are noisy. Home diesel generators may cost anywhere between $1000 for 4KW to $9000 for a 15 KW depending upon the quality, wattage rating and voltage rating. Diesel generators for industrial use are available in the range of 500KW to 2000KW

Generators - A Guide to Purchasing
The diesel generator produces electric energy using the combination of an electrical generator and a diesel engine.
Ships often use diesel generators, to power the electric system and to propel the ship. Wherever the electrical grid is unstable, a diesel generator is used as a back up during supply failure. Even with the best alternative system such as solar energy or wind energy, sometimes the weather may not cooperate and land us in darkness when the main power source fails. To keep our power system running, a backup engine generator may be just the thing. For businesses with sensitive computer networks, or homes with critical medical equipment, a back up power system such as a diesel generator may be necessary even when grid power is available.
The intended power load and the ability to supply the same is the basis for the selection of diesel generators.
High quality gasoline generators and diesel generators will provide reliable backup power to small offices and most homes. When you have a good backup generator sized to support your important electrical equipment and power systems then you need not bother or worry when there is a major supply failure.
Diesel generators can be switched on or off unlike other alternative power sources so there are no need for a dedicated charge controller. The generator can be connected to the main power system through an inverter using the generator’s auto-start feature. Alternatively, it can also be connected to the generator auto-start battery charger.
When buying a diesel generator make a list of the lights and equipment that will be running off the generator. Total the wattage requirements to determine the capacity of the generator. Compare wattage requirement and the price of the generator. If the generator is to be connected directly to the electrical system, then it is advisable to hire a qualified technician to install the transfer switch. Ensure that the generator has adequate storage capacity, longer usage time at a stretch, overload protection and auto shut off facility.

Some Generators Make Good Neighbors
There are generally two main components that make up generators. One part is the motor that burns fuel, which usually consists of natural gas, diesel, propane or gasoline, and the generator head is the second part that is essential. It is the generator head that turns the power into electricity. Whether it is a 5kw generator or a 10kw generator, the motor and the power generator comprise the standard unit. The electricity generated is measured in terms of voltage and watts. Voltage is a measure of the pressure of the current and wattage is more like the measure of volume of electricity being created. It's important that you know the specific voltage your situation calls for, and then you can then take the model that supplies enough wattage for everything you're going to be running. Honda, coleman, and yamaha are three popular manufacturers.
The standard household current is a single-phase 120 volts. The service entrances to most homes have a 120/240-v service, which means they have two 120v circuits. Combined, they provide 240 volts for all of your power- hungry appliances including central air conditioning, water pumps and electric ranges. Made by Honda, the 2000i and the eu models are popular and are known for their reliability. If you have a large business, it's obvious you are going to have varying power requirements. Often you're going to need to have three-phase power, which is better for running heavy-duty motors. Three days’ power in the United States usually produces 120/208 volts or 277/480 volts. Manufacturers such as honda make power generators that are available for all common voltages, but make sure you know the voltage requirements for your business, so you will be able to find the right match.
Wattage is different than voltage, and it's based on your existing circuits and your electrical service. The requirement for wattage increases with each additional appliance or piece of equipment you want to power with your generator. Even your smallest eu or coleman generator produces around 800 watts. Large industrial generators can produce 500 kW or 500,000 watts or even more. For small businesses, you'll find 15 to 100 W are common. There are two types of generators, the standby generator and the portable generator. Standby generators are used to offset the effects felt from power outages and can be permanently installed as an emergency power source for your business. Hardwired into the building’s electrical system, they are designed to be used for only a few short hours at a time. This type of generator is much smaller and less expensive. Most generators have built in the fuel tanks, which allows them to run anywhere and you can plug in ordinary extension cords. The smallest type of generator is under 1 kW with the largest being over 15 kW. The 5kw generator is common for residential use.
There's also a sub-class of tow-able generators that is designed for towing to construction sites. These run on diesel and can produce over 200 kW or more. Generator engines are cooled by water or air, and it’s the air-cooled systems that are the most cost-effective. You will get better temperature control with liquid-cooled generators and they're also quieter, which is especially good if you're considering running these in a residential neighborhood. Please keep in mind that you're going to need an experienced electrician, and pipe fitter to install your unit. This will ensure that you will have many carefree and safe operating hours. If you're in the market for a new generator, visit some user forums and gets some testimonies and make a valuable purchase decision based on a wealth of information available to you right here on the Internet.

Generators - A Guide to Purchasing
The diesel generator produces electric energy using the combination of an electrical generator and a diesel engine.
Ships often use diesel generators, to power the electric system and to propel the ship. Wherever the electrical grid is unstable, a diesel generator is used as a back up during supply failure. Even with the best alternative system such as solar energy or wind energy, sometimes the weather may not cooperate and land us in darkness when the main power source fails. To keep our power system running, a backup engine generator may be just the thing. For businesses with sensitive computer networks, or homes with critical medical equipment, a back up power system such as a diesel generator may be necessary even when grid power is available.
The intended power load and the ability to supply the same is the basis for the selection of diesel generators.
High quality gasoline generators and diesel generators will provide reliable backup power to small offices and most homes. When you have a good backup generator sized to support your important electrical equipment and power systems then you need not bother or worry when there is a major supply failure.
Diesel generators can be switched on or off unlike other alternative power sources so there are no need for a dedicated charge controller. The generator can be connected to the main power system through an inverter using the generator’s auto-start feature. Alternatively, it can also be connected to the generator auto-start battery charger.
When buying a diesel generator make a list of the lights and equipment that will be running off the generator. Total the wattage requirements to determine the capacity of the generator. Compare wattage requirement and the price of the generator. If the generator is to be connected directly to the electrical system, then it is advisable to hire a qualified technician to install the transfer switch. Ensure that the generator has adequate storage capacity, longer usage time at a stretch, overload protection and auto shut off facility.

Diesel Generators Will Keep Your Electricity Flowing Through The Stormy Weather!
If you belong to the majority of people who think the diesel generator is one of those noisy, smoky engines that farmers don't seem to be able to do without, then you are going to have to think again. There is a growing surge, almost a tidal wave of new owners sweeping across the United States. These are the people who through no fault of their own seem to be forever losing their power supply. It is not until you are faced with trying to take care of your family through an extended power outage that you realise just how difficult life becomes without that magical current flowing through the lines.
It seems that storms are becoming more severe, with some badly affected areas having to go without power for between one and two weeks. On the other hand, heatwaves put so much demand on the national grid that rolling outages have to be forced on the population to keep the whole system from crashing. Then of course there are all the other things that can go wrong, such as transformers malfunctioning, but they all mean the same thing, you are left searching for candles and matches in the dark.
The diesel generator has always been regarded as belonging to industry, and indeed this is where you will find the giant units ranging from 20kW to way over 2000kW's that produce the same amount of power as a small power station. You will also find them permanently installed at hospitals, nursing homes, fire and police departments or anywhere that reliable stand-by power is required. Our transportation systems such as air traffic, sea navigation, and radio communications all rely on diesel generators in times of emergencies. In the situation of a natural disaster, it is the diesel generator that will be the heart beat of emergency services and reconstruction.
Many suburban homeowners, RV owners, tradesmen and small businesses are paying the extra, and purchasing a diesel generator in preference to a gasoline powered unit. When there are so many gas generators coming on to the market at such ridiculously low prices you can be forgiven in asking why. The consumer has finally woken up to the benefits of diesel. There are in fact four main reasons why people are turning away from the cheaper gas alternative in their droves.
1. The diesel generator likes to work, and it is very happy putt-putting away 24 hours a day, 7 days a week. It works well under load too, in fact it loves to work hard. Many of the discount and hardware store bought gas generators virtually disintegrate during prolonged use, and you are doing well if they last more than a couple of hundred hours. There are of course very good models, but they will still be more suited to intermittent use, and will need a thorough overhaul at around 1,000 hours. The diesel generator on the other hand won't need anything except regular maintenance - such as oil change, for the first 20,000 hours of its life.
2. Maintenance. No ignition system to give you trouble, no carburettor that needs rebuilding or cleaning, no distributor to go kaput, and no spark plugs to be replaced. Maintenance is simplified on a diesel generator, they are in fact a much simpler system altogether. Regular oil changes as well as replacing the oil, fuel and air filters are all that is required.
3. The diesel generator is way more fuel efficient, and the exhaust is not nearly as toxic as gasoline.
4. Diesel power is synonymous with dependability and for standby or emergency power, this is essential. The quality of the electrical output is also excellent and this means that you are bale to run your computers and electronic equipment with peace of mind.
The cost factor has been a stumbling block for many people, but at the end of the day, the diesel generator is worth every extra dollar and more. It is common for them to outlast their gasoline counterparts by anything up to ten to one. Their work ability has never been questioned, but their noisy and smelly habits have. The diesel generator has cleaned up its act and is now a much quieter and cleaner producer of commercial grade power, and it is fast becoming the preferred choice of all those people who want the best.

Your Diesel Generator Will Ensure the Lights Are On When Somebody's Home
If you're considering putting a permanent power generating system such as a Yamaha generator, in your home or office, this is definitely a job for the experts! Any wiring that is done to the transfer switch and circuit board will need to be done according to your local electrical code and you may need a plumber in to set up the hoses and connect the Yamaha generator to the home's fuel supply.
Diesel generator dealers that are licensed will generally oversee the installation process, and some companies will a secure a permit and schedule the electrical inspection as part of your purchase price. Prices will vary, but you'll find that a 12 kW generator package excluding the transfer switch to be somewhere in the vicinity of US$1,000-$7,000. A 20 kW package will run you somewhere in the vicinity of $8-$10,000. Many brand-name manufacturers are now making home power generating systems such as Generac generators, Honda generators and Kohler more affordable. Most manufacturers encourage homeowners to hire electrical contractors for installation, as these are not do-it-yourself jobs. If you decide to install a permanent diesel generator somewhere outside your home, it should usually be on a concrete pad near the utility meter. Some generators come with a built in mounting pad and you may want to consider these instead of pouring your own concrete pad. As a rule, the unit is usually run off your home fuel supply and you'll need to connect it to the propane or natural gas supply.
The transfer switch is commonly installed inside next to the distribution panel and wiring is run from the generator into the house. Once the transfer switch is connected, it monitors your home's power supply for any interruptions. Backup power from Honda generators or diesel generators is almost becoming a necessity in today's technology-driven world. There are many more electrical items to run now other than lights, heating, cooling system and appliances. Most homes have computer systems, home automation systems and security systems. Electrical regulation has caused complete power outages in many areas and is more prevalent than years gone by.
It is almost essential that when bad weather knocks out your power for days or possibly weeks on end that you have a Honda generator backup power system. A self-contained backup system will help keep your phones ringing, water running, computers running and the furnace keeping your home warm, too. Pipes freezing are also a hazard when power loss occurs, and if you live in an area where intruders could be a problem, your security system on all the time will keep them at bay, too. It's important to understand what a "watt" means if you're going to install a home power generating system. This starts with an assessment of your basic needs, and you'll want to calculate the complete wattage that your home consumes at any one time. If you're at a loss as far as to this calculation, call your electrician and have him do it for you. Such items as heating, cooling, security systems, fans, refrigeration and lighting are some of the items that you need to consider. The size of your diesel generator backup system is based on the essential wattage that you're going to need. When this calculation is done, it is important to remember that you must accommodate the peak power load that these devices will supply. You must make allowances for power surges as well as appliances that are considered to be steady-rate. A good example of a high-demand system with high startup power is your furnace. If your furnace has a low start motor, this will still tax the load a bit. Energy-efficient appliances will directly impact how much load a backup power source can support. If you're in an area that loses power often, you may be well advised to get rid of the energy hogs and replace them with more energy-efficient appliances. If you use electric heat, a gas or wood stove is a great addition. Let a reputable generator dealer in your local area assess your true wattage needs. This way you'll be more confident when you purchase your Yamaha generator system.

History of the Diesel Generator
The diesel generator owes its roots to mainly two inventors. One of these is the creator of the first generator Michael Faraday and the other is the creator of the diesel engine Rudolph Diesel. The first of these two has contributed greatly to life as we know it today with all his discoveries in electricity.
Michael Faraday was of humble beginning but always had a curious nature. He was at an early age an errand boy for a bookbinding shop and here he vastly increased his knowledge as he read anything he could put his hands on. He was very interested in the concept of energy and force and this interest is one that continued throughout his life and eventually he developed into a famed chemist and physicist.
It was his discovery of electromagnetic induction in the year 1831 that led to the development of the modern generator. He used what he termed his induction ring to discover the electromagnetic induction. This was the generation or induction of electricity in a wire by the use of the electromagnetic effect of the current in another wire. This was the first transformer and followed closely with the discovery of the magneto-electric induction process which is the production of a steady electric current.
He attached two pieces of wire by the use of a sliding contact to a copper disc. He rotated the disc through the poles of a magnet and was able to generate continuous direct current. This was the first generator of time. This group of experiments led to the revolutionized generator that we know today.
The diesel generator however owes its development to the inventor Rudolph Diesel. He started off as a refrigerator engineer and eventually found himself working on many heat engine designs. He in 1892 put out a patent that dealt with the method and design of a engine where combustion would take place in the cylinder. He continued to work to this goal and was successful in the production of a diesel engine that produced an efficiency of 75%.
It is the coupling of his diesel engine with the generator that led to the diesel generator that we known today. His design was rather large and very heavy and found more use in industrial applications as a generator. They were used to power pipelines and for electric plants and water plants. Later on they found applications in the mines and in oil fields. The diesel generator is simply the coupling of the diesel engine with an electrical generator and has been use throughout history since its invention for many applications.
The diesel generator has been seen to be the choice of many of the larger companies as it is well suited for industrial use. A major discouraging factor for its use in terms of the retail market has been the fact that it can be rather noisy but this has been reduced greatly from the first diesel generators and is now almost comparable to the gasoline generators. These generators also offer other perks such as increase fuel economy and reduced maintenance costs which can explain their popularity in industrial applications.

Guide to purchasing a Diesel Generator
There are many grades of durability of diesel generators on the market. You will find that the larger the machine the more well built it is to withstand the pressures of use. This is the general concept when it comes to the diesel generator that the larger the generator the better it is designed.
It is essential when considering purchasing a diesel generator that you are sure of what kind of use you will be demanding. It is very common for the diesel generators that are larger to be installed on ships as backups during power failures. There are often systems on ships that use power systems that are related to weather. This is not reliable and as such a diesel generator is a good choice. It is better to opt for the larger models as these are very well designed to handle the load.
Many businesses seeking to protect their sensitive computer networks can also depend on the diesel generator. These are excellent sources of power should the power fail. This is also great for medical equipment such as those that are essential in hospitals and can provide performance that is low maintenance.
When deciding which diesel generator to choose it is important that a list is constructed of the various pieces of equipment that will be using the generator power. This will aid in the determination of the total wattage requirements and therefore determine which capacity of generator will be required.
One of the first points when comparing diesel generators is to determine the wattage requirement and compare this to the price of the particular generator. This is essential as it is important not to overload the system and this will determine the best generator to suit your needs. It is also possible for persons with intermittent generator usage to opt for the diesel generator due to all the perks such as reduced fuel costs and maintenance costs.
It is also advisable that when you purchase your generator that you install it with a transfer switch. This may require a qualified electrician. It is also essential that the generator you choose will have adequate storage as this is important in maintaining the right temperature. You may also need other features such as soundproof enclosures depending on your space limitations as the diesel generator can be quite noisy and is best installed away from homes.
Other features that will be needed for your generator include shutdown systems. There are three major shutdown systems available. These are low oil pressure automatic shutdown kits, over-speed shutdown kits and high temperature shutdown kits. These are all necessary for the protection of any diesel generator that you purchase.
Make sure that the diesel generator you choose is run at a low rpm approximately 1800 rpm to ensure long life. It is better to opt for a generator that is the best in terms of fuel efficiency and if you can opt for a brand name. They may be a bit more expensive but they will tend to have better warranties than the other generic brands on the market.

The speed independent Blackbird system weighs in at 75 lb. and is designed to be belt- or PTO- driven from the engine and is speed independent to offer full power from idle to redline, said Raven.
New generator set filter/silencer
The Santa Fe, N.M., manufacturer said the new filter/ silencer is designed to reduce PM emissions by 85% and carbon monoxide and hydrocarbons by up to 99%. The CleanAIR Filter/Silencer has an all stainless-steel construction and is fully insulated for sound attenuation, the company said.
The concept of the CleanAIR filter/silencer combines the benefits of a silencer for sound reduction and the benefits of diesel particulate filters for emissions control into one space-saving unit.
"We designed our Permit filter/silencer specifically to fit facilities that need to reduce emissions and sound," said CleanAIR Sales Engineer, Daniel Serrano. "By combining our diesel particulate filters with a silencer, the customer no longer needs two separate units that take up a lot of space. Our Permit filter/ silencer does the job of both by eliminating emissions while at the same time providing sound reduction. It also reduces the overall cost."
Available for all stationary engine sizes, the custom-designed Permit filter/silencer is manufactured using 304 stainless steel. Utilizing CleanAIR's integrated approach, the product is designed and manufactured in-house, including: product design; flow, stress and sound modeling; filter catalyzation; and custom fabrication of the silencer shell. Each Permit filter/silencer is fully insulated to reduce heat loss and provide sound attenuation.

Generator drive power pack introduced by Perkins
Perkins Engines has introduced the 1104C-44TAG2 ElectropaK generator drive power pack. First shown at the World of Concrete show earlier this year, Perkins said the hunch of the engine is with an eye on broadening its overall product range in the power generation markets.
Power for the new power pack is Perkins 1104C diesel which is packaged with a skid-mounted cooling system. The 1104C is a four-cylinder, turbo-charged and air-to-air intercooled engine designed for 80 and 100 kW 60 Hz standby applications, as well as 50 Hz prime power needs from 80 to 100 kVA, Perkins said.
Perkins is positioning its 1100 series diesels as its premium emissions compliant platform, with the line available in three-, four- and six-cylinder configurations. For Tier 3, Perkins has increased the 1100 series per cylinder displacement to 1.1 L, and has undertaken aggressive development of the combustion system. Other engineering changes include a fundamental redesign of the cylinder block to create an advanced "open-top deck" structure that Perkins said radically reduces transmitted noise.
Further, the addition of air-to-air charge cooling on the 80 and 100 kVA models has enabled Perkins to offer what it says is six-cylinder power from a four-cylinder package.

Diesel particulate filter regeneration: what Cummins is learning in field tests - Around the World of Diesel
San Diego -- Diesel particulate filters (DPFs) might work "passively" in some applications, but growing field experience shows that many DPFs will need sophisticated engine management or other schemes to avoid failures, Cummins field experience shows.
Example: In tests with 17 "passive" DPFs in a New Jersey Transit (NJT) test program, five cracked or melted, seven failed emissions requirements and seven caused excess backpressure to the engine, Cummins engineer Bruce Bunting explained to the Diesel Engine Emissions Reduction (DEER) workshop here.
Data-logging for a separate project for the U.S. Navy likewise showed that only 30% of vehicle applications would allow DPFs to regenerate passively, and a New York City Transit project with diesel-electric hybrids also showed the need for special heat-boosting measures to ensure DPF regeneration.
"Cold," low-load operations cause excessive soot loading in a DPF. If followed by high-load operation, "uncontrolled" regeneration can crack or melt a DPF.
For the Navy project -- all Thomas school buses with different engines -- data logging indicated that typical duty cycles should have allowed for passive regen, with exhaust temps at 400[degrees]C 10% of the time. Yet in its field tests, Cummins found excessive backpressure, Bunting said.
More issues: DPFs not only must be designed to be able to regenerate in any application, regardless of duty cycle, but also provide "self-monitoring" for problems or service. These systems also must be "easily applied to any application with a minimum of special mapping and test work," he said.
Among the possibilities for fail-safe regen are diesel fuel injection into an upstream catalyst (prior to DPF); injection into an upstream fuel burner to boost DPF temps; DPF electrical heater schemes; an exhaust brake scheme; and engine management (including post-main injection, timing, air/fuel ratio changes, exhaust gas recirculation) combined with an upstream pre-catalyst.
Using an upstream catalyst to oxidize NO to [NO.sub.2] (for soot oxidation) can employ both "passive" and engine management schemes in an exhaust temperature range of about 200 to 400[degrees]C, Bunting showed. By contrast, "catalytically enhanced oxidation" could work at temperatures over 300[degrees]C, while "direct oxidation" (using hydrocarbon injection) works above 450[degrees]C, he showed.
Given the advantage of wide effective temperature range, the engine management/upstream catalyst combo seems to be a logical path for future development. However, integration of combined PM/NOx reduction systems could lead to even more clever schemes, and certain diesel applications might favor special technologies.
Example: In a separate investigation, Cummins tested the Rypos electrically-regenerated soot filter for a gen-set application. This four-month operations test involved two 72kW mobile generator-sets at Edwards Air Force base, with emissions tests by University of Utah.
The Rypos system includes four uncatalyzed sintered metal fiber cartridge elements housed in a metal can. Electric heat regenerates the cartridges sequentially. Electric power for the oxidation conveniently came from the Cummins B9 185 horsepower gen-set itself, although secondary (or extra-large) alternator power could be used in a mobile application.
This first-generation system only filtered 62% of particulates smaller than 10 microns, as it suffered from gasket leaks and a failed cartridge. This has led to an improved design. An "overly aggressive regeneration strategy" also may have penalized system efficiency, he said. So, Cummins aims to test the second-generation system for PM reduction performance and energy efficiency.
Example: In tests with 17 "passive" DPFs in a New Jersey Transit (NJT) test program, five cracked or melted, seven failed emissions requirements and seven caused excess backpressure to the engine, Cummins engineer Bruce Bunting explained to the Diesel Engine Emissions Reduction (DEER) workshop here.
Data-logging for a separate project for the U.S. Navy likewise showed that only 30% of vehicle applications would allow DPFs to regenerate passively, and a New York City Transit project with diesel-electric hybrids also showed the need for special heat-boosting measures to ensure DPF regeneration.
"Cold," low-load operations cause excessive soot loading in a DPF. If followed by high-load operation, "uncontrolled" regeneration can crack or melt a DPF.

Next generation gen-set controls from Controls Inc
Controls Incorporated, the Ohio-based manufacturer of engine and generator set controls, is set to unveil the prototypes of its newest generator control platform. The NextGen controllers are designed to operate with both CAN-capable electronic engines and Tier 1 mechanical engines.
"This new generator control platform has been redesigned from the ground up," said Bob Cowen, president of the company. "The purpose of a total redesign from scratch was to incorporate years of customer feedback into the new product. Redesigning from scratch required a significant investment of nine and resources, but it was determined to be worth it to come out with a new product line that addressed customer feedback on issues such as functionality, flexibility, value and simplicity.
"The new design allows for a high quality product/platform that is very flexible in terms of functionality and features, very cost-effective and simple to install."

The NextGen controllers will be available in two version, the 1.01 for standard engines and the 2.01 for electronic J1939 engines. The NextGen 2.01 control is designed to provide digital monitoring and control of a variety of engine and generator functions. Through CAN-bus communications, it is designed to survey the J1939 data link for engine parameters such as temperature, oil pressure, battery voltage, rpm and engine operating hours, etc., which can be output to an LCD panel. Generator conditions, such as voltage, frequency, etc., are also monitored.
A wide range of other conditions, including coolant level, fuel pressure, coolant pressure, oil level, oil and fuel temperature, intercooler temperature, percent throttle, fuel rate, boost pressure, manifold temperature, air filter differential pressure, exhaust gas temperature, ECM battery voltage, air inlet temperature and rejector pressure, can also be monitored and displayed. A four-button key pad provides access to these additional parameters and other engine and control functions. The unit can also provide system protection and alarms for specified conditions.
The NextGen 1.01 incorporates some of the same features, using analog inputs, outputs and features.
The NextGen systems have been in development for more than a year. "We have been upgrading our technology portfolio over the last several years," Cowen said. "As part of the process, we recently received our first patent that covers several of these technologies.
"Much of the technology that has been developed has been implemented in the new generator control platform. The new product platform will be a first step in bringing to market some of these new circuits/technologies. A new engine control will also be forthcoming as part of this process that will utilize much of the same circuitry/ technology and achieve the same positive benefits and cost-effectiveness."
The key to the NextGen system is a single circuit design that is small in size, according to Cowen. "Minimizing size was certainly one of the design goals.
"The overall goal was to create a product platform that can be individualized to specific customer specifications in terms of functionality and capabilities," he added. "We think of it as "mass customization" or the ability to address a wide range of customer specifications from the most basic through very complex based on the same product platform that can be specified accordingly."
There will be a variety of housing solutions based on customer requests/ specifications, Cowen said. "In addition to providing product functionality and capability options, we wanted the new product to be flexible in how it is housed and easy for customers to install and wire," he noted.
The first of the new units is expected to enter regular production in the first quarter of 2005, with the release of the engine controller to follow.
Aside from the development of its new control system, Controls Inc. has also been busy on other fronts, highlighted by a move from its first location in Sharon Center, Ohio, to a purpose-built, 5600 sq.ft. facility in nearby Medina. "We're having success in the marketplace and needed additional space for assembly, office, testing, storage, etc.," said Cowen. "The new facility was built to our design specifications so that it had the necessary amenities and efficiencies that would improve the business and provide the basis for future growth.
"One of the key benefits with reference to the manufacturing/assembly process is that the facility could be laid out to properly accommodate the assembly process. The proper work flow could be implemented, the proper work stations could be set up, the proper delineation between assembly, storage and shipping could be implemented.

New gen-sets, switch from cummins power generation
Cummins Power Generation, Minneapolis, Minn., has developed new generator sets on both the small and large end of its gen-set range, along with new switchgear for emergency and standby power applications.
The new 150 kW model GGLB spark-ignited natural gas gen-set is designed to provide full-rated standby power for backup and emergency power applications. The new generator set features a heavy-duty GM 8.1 L four-cycle natural gas engine that is torque matched to a high-capacity Newage ac alternator for handling motor starting loads. An electronic governor provides precise frequency regulation for powering sensitive loads and the unit also accepts 100% of the nameplate standby-rated load in one step in compliance with NFPA 110, Level 1, the company said.
"The new 150 kW model GGLB spark-ignited generator set is both user-friendly and environment-friendly," said Colette Weiser, market manager for Commercial Standby Generator Sets, Cummins Power Generation. "The basic control system is easy to operate and includes system protection features, digital engine speed control and transfer switch compatibility. The industrial, spark-ignited V-8 engine burns clean natural gas for exceptionally low exhaust emissions."

A wide range of options and accessories is available with the generator set to allow configuration for specific onsite power applications. The optional PowerCommand 2100 generator set control adds microprocessor-based features such as remote start/stop, integrated voltage regulation, alarm and status message display, output metering and auto-shutdown at fault protection for high reliability.
Several alternator sizes offer selectable motor-starting capability with low reactance, the company said. Available permanent magnet generator excitation delivers enhanced motor-starting and precise voltage regulation for nonlinear loads such as variable speed motor controls and UPS systems. The standard cooling system allows full-rated load operation up to 50[degrees]C ambient air temperature. Available weather-protective and sound attenuated enclosures permit installations at outdoor and noise-sensitive sites.
On the larger end, Cummins Power Generation has introduced a new low-BTU generator set series specifically designed to run on the dilute methane gas mixture produced by natural decay in landfills, sewage digesters or methane emitted from coal seams. The new GQ series generator sets produce a continuous 1570 kW (50 Hz) or 1750 kW (50 and 60 Hz) running on landfill or digester gas containing very low thermal energy, while producing low exhaust emissions. Multiple units can be paralleled for higher power production at larger landfill sites.
"Industry studies indicate that, globally, landfills represent an immense untapped energy resource," said Trevor Passmore, general manager for Energy Solutions, Cummins Power Generation. "In North America alone, candidate landfills can produce enough methane gas to support a total generating capacity of approximately 1500 MW. Currently, much of this potential energy is being flared off or vented into the atmosphere. This new generator set will provide landfill operators, utilities and independent power producers with a proven generating solution to make use of this energy resource. In addition, since methane gas released to the atmosphere has about 20 times the greenhouse effect of carbon dioxide and hence global warming potential, burning methane in a generator set can reduce its environmental impact by a factor of about 20."
Minimum pretreatment is required for the landfill gas to remove particulate matter and excess water vapor. Any additional pretreatment is dependent on the quality of the gas at a particular site and project economics.
Powered by modified versions of the model QSV81G 16-cylinder and QSV91G 18-cylinder natural gas reciprocating engines, the new GQ series 1570 kW and 1750 kW low-BTU generator sets feature an enlarged fuel delivery system, double-safety gas shut-off valves, and special coatings and bearing materials to withstand the corrosive contaminants typical in landfill gas.
A Cummins low-BTU generator at a landfill site in Shrewsbury, England, has accumulated more than 5700 hours of operation. Future installations include a wastewater digester site in the Canary Islands and the Viridor Waste Management landfill near Edinburgh, Scotland. At Viridor, Cummins Power Generation is developing a complete turnkey 3.5 MW power plant using two low-BTU generator sets running on methane from the landfill. The electricity produced at the site will be used to run a nearby cement works. An additional pair of low-BTU generators will be installed during the next two years to take advantage of the site's estimated 20-year supply of methane. "Consistent with our goal of providing total energy solutions, Cummins Power Generation can deliver this new product in a number of ways," says Passmore. "For example, we can deliver a Build-Own-Operate (BOO) power plant, or provide application design, installation and project management for a turnkey power plant. Supply of only the generator set, open or containerized, is also available
