乙醇燃料可有效降低汽车尾气中有害物质的排放和温室气体的排放。从资料看对于10%乙醇的汽油,可比同牌号汽油CO降低30%。MTBE作为抗爆剂在汽油中应用很广,但MTBE难以分解,会对环境特别饮用水产生污染,用乙醇可以代替。介于上述乙醇燃料的优点,本文研究了乙醇汽油E22对发动发动机控制系统(EMS)的影响,尤其对油汽混和气、排放、冷起动等方面进行了研究。
Ethanol fuel can effectively reduce the emission of harmful substances in automobile exhaust and greenhouse gas emissions. From the data for the 10% ethanol gasoline, gasoline than the same grade CO reduced by 30%. MTBE as an antiknock agent is widely used in gasoline, but MTBE is difficult to break down, it will pollute the environment drinking water and replace it with ethanol. In view of the advantages of the above-mentioned ethanol fuel, this paper studies the influence of ethanol gasoline E22 on the engine control system (EMS), especially the aspects of oil-gas mixture, emission and cold start.
