摘要
汽车排气系统主要排放发动机工作所排出的废气,同时使排出的废气污染减小,噪声减小。然而排气系统的结构设计存在缺陷,导致发动机的动力性能和排气管的使用寿命降低,影响行车安全。文章根据排气系统的组成和工作原理,结合实际应用情况,分析缺陷产生的原因,针对性地采用了相关改进措施,提高了发动机的动力性能和排气管的使用寿命,为汽车的安全运行提供了可靠保障。
The vehicle exhaust system mainly emits exhaust gases from the engine work,At the same time,the exhaust gas pollution is reduced and the noise is reduced.However,there are defects in the tructural design of the exhaust system,resulting in reduced power performance of the engine and reduced service life of the exhaust pipe,and affect the safety of railway operation.According to the composition and working principle of the exhaust system,combining with the practical application,this paper analyzes the causes of the defects,and takes relevant improvement measures to improve power performance of the engine and service life of the exhaust pipe,which provides a reliable guarantee for the safe operation of automobile.
