Bowers Engine, the Kent, Wash.-based engine distributor and power systems manufacturer, has unveiled its Bulldog Power Systems line of marine generator sets powered by water-cooled, Lister-Petter Alpha Series diesel engines. The new line features two-, three- and four-cylinder models designed to provide 6.75 to 15 kW, as well as a four-cylinder, turbocharged model with a peak power rating of 20 kW.
"Lister-Petter engines were chosen to power the new line of generators for their low maintenance requirements, 250-hour oil change cycle, hydraulic lifters eliminating the need for valve adjustments, and a heavy crankshaft allowing full power to be taken from either end of the engine," said David Rowland, sales engineer at Bowers.
The bottom end of the Bulldog line is powered by the 11 hp, two-cylinder, Lister-Petter LPW2 diesel engine, which generates 6.75 kW. Next is the 16.5 hp, three-cylinder, Lister-Petter LPW3 diesel engine, generating 11.5 kW. The third Bulldog gen-set comes in at 15 kW, and is powered by a 22 hp, four-cylinder, Lister-Petter LPW4 diesel engine. The high end of the line generates 20 kW, and is powered by the 31.9 hp, four-cylinder, Lister-Petter LPW4T diesel engine. All of the diesels utilized in the new line operate at 1800 rpm.
The engine packages feature oil and air filtration components from Lister-Petter and include keel or heat exchanger cooling systems supplied by Orca Manufacturing, Bellingham, Wash. Heavy-duty, industrial grade wet/dry mufflers are also utilized in the package.
Newage Stamford BCA or BCI series a.c. brushless generators with AVR are close coupled to the engines and are available in single- or three-phase outputs. Steel drip pans with vibration isolation mounts from Korfund are standard, with a simpler steel skid available as an option. Safety shutdown systems for oil pressure and temperature are also standard with the new line, and are supplied by Lister-Petter or Murphy.
