| 摘 要： | 在原柴油机的基础上 ,采用进气道多点电控顺序喷射单一气体LPG闭环控制并加装三效催化器系统 ,通过多项试验得到了改造后发动机的热负荷变化规律 ,并有效地降低了热负荷。在ECU严格控制过量空气系数的情况下 ,使改造后的燃气发动机的动力性、经济性以及排放性等性能参数既满足预定目标 ,又能使其排放指标达到欧Ⅱ标准。

| Abstract: | Spark ignition a LPG engine with multi-point sequential fuel injection and three-way catalyzator was modified from a diesel engine.Thermal load behavior of the LPG engine was investigated on a engine test rig and improved effectively.When the air-fuel ratio of the engine is closed-loop controlled precisely,not only its power and fuel economy reach the target,but also its exhaust emissions meet the EURO Ⅱ limits. |

| Keywords: | heat load single LPG electric control multi-point sequential fuel injection diesel engine |
