Development of a heavy-duty natural gas engine to improve its lean operating characteristics is detailed in this paper. Testing to determine the lean misfire limit is described, as well as investigations into the cause of lean misfire in this engine. Details of engine modifications to improve the lean misfire limit are also included. The development process resulted in a significant improvement in the lean performance of the engine (i.e., an extended lean misfire limit, better combustion stability, and lower hydrocarbon emissions).
