Westport's natural gas engine and liquefied natural gas (LNG) fuel system for heavy-duty class 8 trucks offers industry-leading emissions, including lower greenhouse gas emissions, than comparable diesel engines, and allows trucking fleets to move to lower-cost, domestically available natural gas and/or biogas. Based on the industry-leading Cummins ISX diesel engine with cooled EGR, the LNG version of the engine offers the same horsepower, torque, and efficiency as the base diesel engine it is replacing. The engine uses high pressure direct injection (HPDI) technology developed by Westport. The Westport LNG fuel system comprises LNG fuel tanks, proprietary Westport fuel injectors, cryogenic fuel pumps and associated electronic components to facilitate robust performance and reliable operation. The system is 2007 EPA and CARB certified to 0.8g/bhp-hr NOx and 0.01g/bhp-hr PM.
The Westport engine is fuelled with LNG – a safe, cost effective, low carbon, and low emissions fuel – and is available with 400 and 450 horsepower ratings and up to 1,750 lb-ft torque for heavy-duty port, freight and vocational applications. LNG fuel tanks can be configured to suit customer range requirements. LNG engine-powered heavy-duty trucks are eligible for federal tax credits in the United States and may be eligible for other state-specific emissions credits.
