摘要
低碳混合醇是以甲醇或乙醇为主,混合有甲醇或乙醇以及丙醇、丁醇、戊醇等醇的多醇共溶体。低碳醇与汽油混合代用燃料受到各国的普遍重视。在电控汽油机参数未作任何调整的情况下,对低碳混合醇汽油进行了发动机动力经济性以及排放特性的研究,经发动机台架试验结果表明,所研制的低碳醇汽油与车用无铅汽油理化性质相当,且具有良好的排放特性,可有效降低THC、CO的排放。与基础汽油相比,加剂后的全配方低碳醇汽油CO排放平均降低51%;THC排放平均降低18%。
The mixed alcohol is the mixture of methanol, ethanol, propanol, butanol and pentanol, etc. , in which the main components are methanol and ethanol. More attentions have been paid to the mixed alcohol-gasoline blend fuels. This paper presents the emissions of the mixed alcohol-gasoline blend fuels in a spark-ignition engine. The properties of the blend fuels were evaluated. The results show that the mixed alcohol-gasoline fuels possess the same properties as the conventional automotive SI engine fuels, and the blend fuels have the advantage of low THC and CO emissions over the plain gasoline. Averagely, CO is decreased by 51% and THC is decreased by 18% .
