试验研究了无水乙醇、分散剂和水对含醇汽油质量及贮存稳定性的影响。结果表明 ,当无水乙醇体积分数为 10 %～ 15 %时 ,用洛阳石油化工总厂 90号无铅汽油可以调合出满足GB 17930— 1999要求的 93号含醇汽油。水含量小于 0 .4%时 ,该汽油在 -10℃条件下存放不会发生分层现象。按选定配方调合了 2 0t含醇汽油大样 ,台架试验表明 ,该样品的动力性能与普通 93号汽油相当 ,尾气中HC和CO排放量分别降低了 18.5 %和 2 2 .4% ,最低燃料消耗率降低了 4.2 5 %。
The effects of ethanol, dispersant and water on the quality and storage stability of alcohol-containing gasoline were studied. The results show that when the volume fraction of absolute ethanol is 10% ~ 15%, the No.93 gasoline with gasoline can meet the requirements of GB 17930-1999 by using 90 unleaded gasoline at Luoyang Petrochemical General Factory. When the water content is less than 0.4%, the gasoline can not be delaminated when stored at -10 ° C. According to the selected formula blended 20t gasoline-containing large sample, the bench test showed that the dynamic performance of the sample and ordinary 93 gasoline equivalent HC and CO emissions were reduced by 18.5% and 22.4% , The lowest fuel consumption rate decreased by 4.2 5%.
