The new engine works for a number of on-highway applications, including school and transit buses, recreational vehicles, vocational trucks, tow and utility trucks, garbage trucks and delivery fleets.
The 8.8 liter liquid-injected propane engine is designed for diesel-like power and performance, and it produces 270 hp at 2600 rpm and 565 lb-ft at 1500 rpm. The low-speed engine supports SAE 2 and SAE 3 transmission interfaces, which offers original equipment manufacturers many more transmission options.
All PSI 8.8 liter engines come standard with advances front accessory drives. Additional features include 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.
According to Gary Winemaster of PSI, the company’s alternative fuel engines are a cleaner and less expensive solution when compared to diesel engines. He added that the new 8.8 liter 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.
The approval comes as increased attention is being focused on how to make large scale use of alternative fuel vehicles a reality.
Many companies are actively looking at how to implement or increase their usage of alternative-fueled fleets. Some, such as AT&T, have gone as far as to set target goals for alternative fuel vehicle deployment.
According to a report by the American Clean Skies Foundation, by allocating just 20 percent of its $150 billion transportation services budget to carriers that fuel their fleets with domestically produced natural gas, electricity, biofuels and other alternatives to diesel and gasoline, the US government could save taxpayers up to $7 billion annually and about $25 billion by 2025.
