中冷器的使用与维护

涡轮增压发动机排出的废气温度非常高,经过增压的空气经进气歧管、进气门流至汽缸燃烧室,很容易导致发动机燃烧温度过高,导致燃油的不规则预燃而发生爆震,产生降低增压效果、损坏发动机等一系列不良后果,因此需要加装中冷器来降低进气温度。本文主要介绍了中冷器的使用原因、工作原理、作用与副作用、分类、主要故障和维护方法等。

The use and maintenance of intercooler

Turbochargedengine exhausttemperature is very high, after apressurizedair through theintake manifold,intake valveflow to thecylinderchamber, can easily lead toengine combustiontemperature is too high, resulting inpre-ignitionandfuelexplosionoccurredirregularlyshock, resulting inreducedsupercharging effect,damage to the engineand a series ofnegative consequences, soyou need to installthecoolerto reducethe intake air temperature.This paper describes theuse ofreasonin the cold, working principle,the role andeffects,classification,maj orfaults andmaintenancemethods.
