VANCOUVER, B.C., Canada --- Cummins Westport Inc. (CWI), a leading provider of alternative fuel engines, announced that North American Bus Industries (NABI) has ordered 260 compressed natural gas (CNG) CWI ISL G engines for CompoBus buses.
"Production is underway to fill this significant order from NABI," said Guan Saw, CWI’s president. "The ISL G, our flagship engine, continues to gain market share in the North American transit fleet. The ISL G offers operators the benefits of meeting EPA 2010 emissions standards today, with the robust performance and reliability they require."
The NABI CompoBus is a 45-foot vehicle made from a lightweight composite material that weighs roughly the same as the company's traditional 40-foot bus, enabling it to provide a lower operating cost per passenger mile as compared to buses with traditional steel structures.
The ISL G surpasses EPA 2007 phase-in levels and meets 2010 emission standards of 0.2 g/bhp-hr (grams per brake horsepower hour) NOx (nitrogen oxide) and 0.01 g/bhp-hr PM (particulate matter).
