Westport LNG System for Heavy-Duty Trucks
Westport's liquefied natural gas (LNG) system for heavy-duty trucks offers class-leading emissions performance while maintaining equal horsepower, torque, and efficiency to a diesel-fueled engine.

The application of Westport's LNG system to the Cummins ISX engine substantially reduces greenhouse gases (GHG) and other air contaminant emissions, to well below standards set by the U.S. Environmental Protection Agency (EPA) for 2007 heavy-duty on-road applications.

The Westport engine is fueled with LNG-a safe, cost effective, low carbon, and low emissions fuel. Westport gives users fuel capacities ranging from 33 to 112 diesel equivalent gallons (DEG). With matching or better fuel efficiency (depending on operation), vehicle range can be tailored to suit customer applications.

The Westport LNG system is available with 400 and 450 horsepower ratings and up to 1,750 lb-ft torque.
