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,遇低温结冰的现象进行了实地调查拍照,通过冬季和春季在高速公路行车、市区行车、哈尔滨市环路行车、平路和坡路怠速对比实验验证了调查路面结冰多发地段的一致性。分析了排气管中水分形成机理,排气中水含量的影响因素,提出了排气管水蒸汽疏导和调控措施。Aiming at the actuation that the water is discharged from the exhaust pipe and dripping to the pavement, the case of low-temperature freezing,we took field survey photos and proved consistency of the pavement which is freezing frequently through the contrast tests of highway driving, crowded urban driving,loop road, flat road and idling speed in the winter and spring in Harbin. This paper analyzes the formation mechanism of water in exhaust pipe, factors of water content from the exhaust and puts forward measures of regulating and controlling the water of the exhaust.
