Cummins Westport Inc. (CWI) today announced the ISB6.7 G, a 6.7 litre midrange, factory built natural gas engine is now fully available as a production engine for shuttle bus, medium duty truck, and vocational applications in North America. As previously announced, the engine has been availabile for school bus applications since May 2016 from Thomas Built Buses. The 6.7 litre engine platform has large OEM availability for midrange trucks, vocational trucks and mid size buses and the expansion of applications potentially available for the ISB6.7 G engine more than doubles its addressable market.
The ISB6.7 G is based on the Cummins ISB6.7 diesel engine platform, the industry leader in the Cummins midrange engine family, and operates exclusively on natural gas, including compressed, liquid, or renewable natural gas (RNG). The ISB6.7 G is the second engine from CWI to receive emission certification from the U.S. Environmental Protection Agency (EPA) and the Air Resources Board (ARB) in California for meeting the Optional Low NOx Emissions standards.
