New Flyer Introduces the Cummins Westport ISL G Near Zero Emissions Engine
New Flyer of America announced it will begin installing the 2016 Cummins Westport ISL G Near Zero engine on its Xcelsior buses starting the third quarter of 2016. New Flyer is the first transit manufacturer to offer the industry’s cleanest engine and will also deliver the first OEM installation of the engine.
The ISL G NZ CNG engine will be used to power a New Flyer Xcelsior XN40 bus for the Los Angeles County Metropolitan Transportation Authority (LA Metro), which operates the largest natural gas engine transit vehicle fleet in North America.
“We are proud to be the first OEM to factory install and deliver this industry-leading clean engine to a transit customer,” said Wayne Joseph, New Flyer Executive Vice President, Bus. “The advancements of Cummins Westport in compressed natural gas internal combustion and after-treatment technology has helped our customers meet stringent clean air requirements, powered by low cost natural gas.”
The ISL G NZ NOx natural gas engine is the first mid-range engine in North America to receive certification to meet the 0.02 g/bhp-hr. Near Zero NOx Emissions standards from both U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). In addition to the dramatic reduction in NOx, the ISL G NZ features Closed Crankcase Ventilation to reduce engine related methane emissions by 70 percent.
