摘　　要：针对我国北方地区冬季因为车辆排水造成路面结冰的现象,本文通过理论计算和环境舱内实车试验测量这两种方式研究低温条件下车辆的排水特性。尤其对燃用乙醇汽油和普通汽油这两种燃料的车辆在不同温度点不同驾驶工况进行了对比试验,并对试验的结果加以总结分析。该研究的成果将对城市道路结冰现象的量化分析及相关治理工作起到积极的作用。Concerning the phenomena of road freezing in north of China in winter for vehicle＇s water emis-sion, this paper use theoretical arithmetic and real car environment test to research performance of water emission of vehicle in low-temperature environment. Especially for vehicle using gasoline or ethanol gaso-line, we carried out several contrast tests at different temperatures by different driving cycles, and then sum-marized the test results. The research findings will play a positive role on quantitative analysis and resolution to city road freezing.
