Westport GX Engine
Westport Innovations Inc., a global alternative fuel, low-emissions transportation technologies provider, has been certified by the U.S. Environmental Protection Agency (EPA) to 2010 emissions compliance for the Westport GX 2010 15L engine. The GX engine is certified and compliant to 2010 emission limits of 0.2 g/bhp-hr oxides of nitrogen (NOx) and 0.01 g/bhp-hr particulate matter (PM) without the use of emissions credits. Adding to the U.S. certification, Australia’s Department of Infrastructure, Transport, Regional Development and Local Government has certified the Westport GX engine in compliance with the Australian Design Rules (ADR) 80/03, which takes effect for all heavy-duty truck models starting January 2011.
“With EPA certification, Westport’s GX engine meets the most stringent current North American emissions standards, in addition to providing fleets the energy security and robust performance the GX is known for,” said Jonathan Burke, Vice President of GX Sales & Market Development at Westport. “2010 trucks with the Westport GX engine, now available for sale to interested customers in North America, will have superior fuel economy while maintaining high reliability and performance.”
The Westport HD System features the Westport GX 15L engine – based on the Cummins ISX diesel engine with cooled exhaust gas recirculation – and Westport’s liquefied natural gas (LNG) fuel system (LNG fuel tanks, proprietary Westport fuel injectors, cryogenic fuel pumps). The Westport GX is available in power ratings of 400-475hp and torque ratings of 1450-1750 lb/ft. Factory installation of the GX is available in both Kenworth and Peterbilt tractors.
