Effect of Ethanol-Gasoline Blends from Different Base Gasoline on Performance of Automobile

The experiments were carried out on a 1.6 L automobile fueled with ethanol-gasoline blends from different base gasoline to study its performance.The results show that compared with the lead-free gasoline,the performances improve or keep the same when the automobile is fueled with ethanol-gasoline blend from pure gasoline without MTBE,but the performances deteriorate when the automobile is fueled with the blend from lead-free gasoline added with MTBE.In the latter case,the oxygen content in the fuel is too high to meet the demand of the electronic control system.It is recommended when using ethanol-gasoline blend in the automobile,the gasoline in the blend should be the pure gasoline without any oxygenants such as MTBE.
