Alternative-fueled engine maker Power Solutions International has received certification from the U.S. Environmental Protection Agency that the company's 8.8-liter propane and natural gas fueled engine can be used for on-highway applications.

The new engine suits a wide range of on-highway applications, including vocational trucks, school and transit buses, delivery fleets, recreational vehicles, tow and utility trucks, and garbage trucks, according to the company.

"We recognize the need for our customers to have flexible power solutions that address emissions regulations," said Gary Winemaster, chairman and CEO. "Our alternative-fuel engines are a cleaner and considerably less expensive solution when compared to diesel. With this engine, we offer on-highway OEMs a quality alternative that meets their performance, compliance and economic demands, while providing the flexibility to choose the best fueling strategy today and in the future."

Winemaster said the new engine solves two key problems in today's alternative fuel engine market: the limited range of available platforms and the quality and performance shortcomings of current products.

OEMs in primarily diesel-driven industries have sought alternatives, but have not found systems that meet their size and power range requirements, according to the company.

PSI's 8.8-liter liquid-injected propane engine is designed for diesel-like power and performance, producing 270 horsepower at 2600 rpm and 565 pounds feet of torgue at 1500 rpm. The low-speed engine supports SAE 2 and SAE 3 transmission interfaces, which offer OEMs many more transmission options, said Power Solutions International.

All PSI 8.8-liter engines come standard with advanced front accessory drives, including the following features: an 8-groove belt, an electronically controlled viscous fan clutch, an integrated pad-mounted alternator that supports up to 320 amps, and a pad-mounted AC compressor.

PSI developed strategic partnerships with Delphi, for advanced controls, and Ricardo, for testing, validation and certification of the engine.
