摘要：
To improve the performance of compressed natural gas (CNG) engines, CNG in-cylinder direct injection was implemented with a rapid control prototype (RCP) technique. According to application requirements, the flow characteristics of the direct injector was tested, a gas supply system for the CNG direct injection engine was designed, and the control strategy for the CNG in-cylinder direct injection was made. The experiment results show that the output torque of the CNG in-cylinder direct injection engine could reach the output level of a gasoline engine of the same kind. At the rotational speed of 2 500 r/min, the power loss of the CNG in-cylinder direct injection engine compared with the gasoline engine was only 0.006%.
