Westport HD engines and liquefied natural gas (LNG) fuel systems
for class 8 trucks offer 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 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 Westport LNG system is 2007 EPA and CARB certified to 0.8g/bhp-hr NOx and 0.01g/bhp-hr PM.
The Westport GX 15L 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.
