Abstract

In an inline four-cylinder gasoline engine,the influence of the mixed fuel of ethanol and gasoline on the performance of engine has been studied.The results show that dynamic performance of the engine is lower at a low speed and is higher at a high speed,when the structure and technical parameters of the engine remain unchanged,but modest changes;fuel consumption rate is increased;emission performance improves obviously.At last,the best-mixed ethanol rate is identified by vague comprehensive evaluation method.
