摘　　要：基于稳压源废气控制阀的控制机理,试验研究不同工况下的稳压源废气控制阀对发动机性能的影响,通过试验得出:稳压源废气控制阀可以降低发动机低负荷工况的泵气损失,提高发动机经济性1%~2%。Based on the control mechanism of the control valve,the influence of the control valve on the engine performance under different working conditions is studied experimentally.The results show that the control valve can reduce the pumping loss of the engine under low load condition and improve the engine economy by 1%~2%.

关 键 词：稳压源废气控制阀 天然气发动机 负荷特性 瞬态响应
