Liquefied Natural Gas System for Heavy-Duty Trucks
The Westport GX engine offers class-leading emissions performance while maintaining equal horsepower, torque, and efficiency to a diesel-fueled engine.
The application of Westport high-pressure direct injection (HPDI) technology to the Cummins ISX engine substantially reduces greenhouse gases (GHG) and other air contaminant emissions.
The GX engine is certified to 2010 U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emissions standards.
Westport HD powered LNG truck
21–27% less GHG compared to diesel
The Westport GX is fueled with liquefied natural gas (LNG)—a safe, cost effective, low carbon, and low emissions fuel. Westport provides operators with fuel capacities ranging from 52 to 104 diesel equivalent
gallons. With matching or better fuel efficiency (depending on operation), vehicle range can be tailored to suit most operator applications.
The Westport GX is currently available in factory assembled Kenworth T800 LNG and Peterbilt 386 LNG and 367 LNG models and is offered for use in various applications including port drayage trucks, heavy-haul trucks,
refuse transfer, dump trucks, roll-offs, line-haul, and other vocational applications. Contact Westport HD for more information and to find your local dealer.
