WINNIPEG — New Flyer Industries Inc. has added a clean air propulsion option for its New Flyer Xcelsior bus family with the Cummins Westport ISL G Near Zero emissions engine.

The Winnipeg bus maker’s New Flyer of America Inc. subsidiary will deliver the first OEM installation of ISL G NZ engine in the third quarter.

The compressed natural gas engine will power a New Flyer Xcelsior XN40 bus for the Los Angeles County Metropolitan Transportation Authority (LA Metro). LA Metro operates the largest natural gas engine transit vehicle fleet in North America.

Cummins Westport Inc. developed the natural gas engine, the first mid-range engine in North America to receive certification for meeting the 0.02 g/bhp-hr. optional Near Zero NOx Emissions standards from both the US Environmental Protection Agency (EPA) and the Air Resources Board (ARB) in California.

Cummins Westport, based in Vancouver, says this certification represents a 10-fold emissions reduction below current EPA standards, making it the cleanest engine in the industry. The engine operates 90% below the particulate matter standard, and 16% below the C02 emissions standard. A closed crankcase ventilation reduces engine related methane emissions by 70%.
