摘　　要：燃气发动机采用节气门控制进气流量,采用放气阀控制进气增压,通过实际进入缸内的空气量结合理论空燃比计算得到的燃气量来控制燃气喷射和点火。分析了节气门控制、放气阀控制与两者耦合控制,并对节气门与放气阀的耦合控制进行试验、标定,最终得到兼顾燃气发动机动力性和经济性的最优控制方法。Gas engines use a throttle valve to control the intake air flow,and use a bleed valve to control the intake air boost.The fuel gas injection and ignition are controlled by the actual air amount entering the cylinder combined with the fuel gas amount calculated from the theoretical air-fuel ratio.The throttle control,bleed valve control and their coupling control were analyzed,and the coupling control of throttle valve and bleed valve was tested and calibrated.Finally,the optimal control method taking into account the power performance and economical efficiency of the gas engine was obtained.
