摘　　要：对电控液化石油气 (LPG)发动机进行了试验 ,测量了发动机在几个代表性转速下 ,CO、HC及 NOx 的排放指标 ,并对其排放特性进行了分析 .对化油器发动机改装成电控 LPG后的发动机动力特性进行了试验 ,并与原发动机的动力性进行了比较 .试验表明 :电控 LPG发动机在基本保持原发动机动力性的基础上 ,可以使有害物排放大幅度下降 。This test is used to investigate the electronic-controlled LPG engine by experimental ways, measuring the amount of CO, HC and NOx emission under the representative speed, analyzing the characteristics of EC-LPG engine emission and the influence to the power output. The results show that EC-LPG engine can lower CO, HC, NOx poisonous emission remarkably and satisfy the new environmental legislation, keeping the power output almost the same as the gasoline engine without any change made.
