EGR（废气再循环）阀有助于降低汽车的排气排放（从尾管中产生的气体）。它通过放回进气歧管来循环从发动机出来的气体部分，在那里发动机可以再次燃烧，从而减少了排放。
The EGR valve is located in the engine compartment (underneath the hood). Most engines require exhaust gas recirculation to meet emissions standards. If the EGR valve has gone bad, the car will not pass emissions.
During the EGR valve replacement, your mechanic should also inspect the vacuum hoses connected to the EGR valve. If the vacuum hoses are cracked (leaking), the EGR valve will not function properly.
It is a good idea to get an air induction (carbon cleaning) service performed every 50,000 miles. This will clean out any sludge or carbon build up in the air intake system. Always keep up with regular oil changes; it will help prevent sludge build up in the engine.
EGR阀可帮助您的车辆回收气体。EGR阀负责从发动机中取出的气体，并通过进气歧管将其发送到发动机可以再次利用它。如果没有EGR阀，您的车辆将无法回收并重复使用其任何气体，从而增加排放。没有EGR，您的汽车将不会通过排放检查。
