不同基础汽油配制的乙醇汽油对汽车性能的影响

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

在一辆排量为1.6 L的汽车上进行了燃用不同基础汽油配制的车用乙醇汽油对汽车性能影响的试验研究。结果表明:与无铅汽油相比,燃用不含MTBE纯汽油配制的乙醇汽油,汽车性能有所改善或不变;而燃用含MTBE无铅汽油配制的乙醇汽油,汽车的性能下降,其主要原因是燃料中氧含量增加较多,与汽车的电控系统不匹配。因此配制乙醇汽油的基础汽油应使用不含任何含氧化合物的纯汽油,而不能使用含MTBE的无铅汽油。

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 resuhs 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 istoohigh 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.
