| 摘 要： | 根据乙醇燃料的理化特性对电控喷射点燃式汽油发动机进行了改进,研究了进气温度和点火正时对乙醇发动机性能和排放的影响。试验结果表明:需采用进气预热解决乙醇发动机冷起动;乙醇发动机的动力性与汽油机基本相当,比能耗比汽油机低5%以上,CO和HC排放改善30%以上。

| Abstract: | The electronically controlled injection spark-ignition gasoline engine was improved according to physical and chemical characteristics of ethanol fuel.Then the effects of the intake temperature and ignition timing on ethanol engine performance and emission were investigated.The results showed that the intake air preheating need be adopted to solve the cold start problem of ethanol engine.The power performance of ethanol engine was equivalent to that of gasoline engine,but the specific fuel consumption was reduced by more than 5 percent,and the CO and HC emissions was decreased by over 30 percent. |
