摘　　要：针对冬季哈尔滨市乙醇汽油车从排气管中有水排出,滴落到路面,遇低温结冰,对行车带来困难的应用实际状况,在冬季和春季进行了高速公路行车试验、市区行车试验、哈尔滨市环路行车试验、平路和坡路怠速对比试验。测量出乙醇汽油车各工况排气管中随废气排出水的含量以及排气管中各个点的温度变化情况,为疏导和调控排气中水分提供了基础数据。Aiming at the actuation that the water is discharged from the exhaust pipe and drop to the pavement, the case of low-temperature freezing, this will bring difficulties for driving in cold area. In the winter and spring, we do the tests of highway driving and crowded urban driving and in Harbin city loop road, idling speed contrast. The change of exhaust＇s water and temperature of ethanol-gasoline vehicle in cold area are obtained. These provide basic data to regulate and control the water of the exhaust.
