【 摘 要 】

Subcontractor report details results of on-road development and emissions characteristics of C-Gas Plus natural gas engine in Viking Freight heavy duty trucks. The objective of this project was to develop, on road and in service, a natural gas truck/bus engine (the C-Gas Plus) with higher horsepower, lower cost, and better performance and diagnostics than the previous C8.3G natural gas engine. The engine was to have an advanced engine management control system to enable implementation of proven technologies that improve engine performance and power density (hp/L). The C-Gas Plus engine was designed to meet the following objectives: (1) Higher engine ratings (280 hp and 850 ft-lb torque for the C-Gas Plus) than the C8.3G natural gas engine; (2) Lower capital cost than the C8.3G engine; and (3) Low emission standards: California Air Resources Board (CARB) low-NO{sub x} (oxides of nitrogen) (2.0 g/bhp-h) and U.S. Environmental Protection Agency (EPA) Clean Fuel Fleet Program ultra-low emission vehicle (ULEV) emission certifications.
