文章针对我国不同装置供油系统发动机的在用车(化油器、电子喷射、增压柴油机与非增压柴油机4种类型)的尾气排放进行了海拔高度的对比试验,通过数据分析处理,得到了各种发动机的尾气排放随海拔的回归曲线而变化的结果,同时也进行了曲线的理论分析,还对影响汽车排放的各相关因素进行了相关性的分析,从而得出了排放结论。
In this paper, we compare the exhaust emission of the vehicles (carburetor, electronic injection, turbocharged diesel engine and non-turbocharged diesel engine) with different units of oil supply system in our country, and compare them with the data obtained from the data analysis and processing The exhaust emissions of various engines vary with the regression curve of altitude. At the same time, the theoretical analysis of the curves is also carried out. Relevant factors that affect the emissions of vehicles are also analyzed, and the conclusion is drawn.
