摘　　要：灵活燃料发动机即可以使用任意配比的乙醇和汽油的发动机。本文首先对乙醇和汽油的理化性质进行了深入的分析,然后通过计算机模拟和试验的方法研究了不同热值的燃料对发动机机械性能、电控系统及排放特性的影响。阐述了使用任意配比的乙醇和汽油的灵活燃料发动机的开发思路,并结合具体的案例阐明了灵活燃料发动机的工程可行性和广阔的应用前景。Flexible fuel engine can use free ratio mixed fuel of ethanol and gasoline. This paper first deeply analyzes the physics and chemistry character of ethanol and gasoline. Then the influences of the fuel of different thermal values to the mechanism performance, electronic control system and emission are studied through the method of simulation and experiment. Based on this, the development route of the flexible fuel engine using free ratio mixed fuel is illuminated. Finally, the detailed engine project example proves the feasibility of flexible fuel engine and wide application foreground.
