在北方冬季,使用乙醇汽油汽车尾气中的水蒸汽会在排气管壁冷凝成水滴,并随排气流排至路面,不仅造成冬季行车拥挤,更增加燃油消耗,存在安全隐患。针对上述问题,分析汽车排气凝水结冰机理,在尽量少地影响汽车原有排气系统下,通过改进实验环境,搭建实验平台进行怠速时排气管凝水温度分布实验研究。实验证明:汽车尾气中水的气液分离临界集中在发动机排气管的消音器区域。本研究论证减少排气结冰的可行性,为实际的应用推广提供技术参考。
在北方鼕季,使用乙醇汽油汽車尾氣中的水蒸汽會在排氣管壁冷凝成水滴,併隨排氣流排至路麵,不僅造成鼕季行車擁擠,更增加燃油消耗,存在安全隱患。針對上述問題,分析汽車排氣凝水結冰機理,在儘量少地影響汽車原有排氣繫統下,通過改進實驗環境,搭建實驗平檯進行怠速時排氣管凝水溫度分佈實驗研究。實驗證明:汽車尾氣中水的氣液分離臨界集中在髮動機排氣管的消音器區域。本研究論證減少排氣結冰的可行性,為實際的應用推廣提供技術參攷。

In winter in north of China ,vapor in automobile emission will freeze on the wall of emission pipes because of using ethanol gasoline ,and outflow onto roads .This is a common phenomenon which not only causes traffic jam and safety problem ,but also increase fuel consumption .This paper aims to problems mentioned above to improve emitting system to reduce or eliminate freeze on roads caused by drain water due to combusting ethanol gasoline under the condition of less influence on original emission system as possible as we can do .Moreover ,technique reference will be provided for practice application through building experiment platform , designing experiment program to analyze experiment results and proof experiment data to present feasibility of reducing emission freeze .
