Document Description
Gas Technology Institute (GTI) and Cummins Westport Inc. (CWI) will utilize the ISB6.7 spark ignited natural gas engine and further develop an advanced version of this engine with heavy duty on-board diagnostics to meet 2018 EPA and ARB regulations for alternative fueled heavy duty vehicles. A number of tasks will be completed to address integration barriers currently preventing the ISB6.7 G to work within existing vehicle chassis and also the mounted engine control unit (ECU) which allows the ISB6.7 G to work within existing vehicle chassis and also the compatibility with a hydrostatic drive which is utilized in street sweeper applications. This engine will them ne deployed in a number of vehicles in multiple applications including street sweepers, shuttle buses and school buses in California where the development tasks conducted will be utilized in real world operation and validated over a variety of duty cycles applicable to those vehicles (i.e. Shuttle Bus, sweeper, and school bus) with the performance measured and assessed. CWI will be targeting existing end-users of CWI ISB6.7 G engines and also those that may currently be utilizing ISB6.7 diesel engines and wanting to convert their fleet to natural gas.
