EGR stands for exhaust gas recirculation.废气再循环主张排气再循环。 The EGR valve will generally make the car run poor at lower speeds or idle, but can effect it anywhere.该排气再循环阀一般会，使汽车运行穷人在较低的速度或闲置，但它的效果可以在任何地方。 The valve should not open at idle.该阀不应该公开在闲置。 Operate at midrange speeds and quit again before wide open throttle.在运作中端的速度和结束前，再次大开油门。 The egr valve is usually located on the intake manifold or head.该排气再循环阀通常设于进气歧管或头部。 There is a diaphram in the egr valve.有一个连续在排气再循环阀。 The valve uses manifold vacuum on the diaphram to lift or close a valve allowing exhaust gas to enter the intake manifold.阀门的用途多方面的真空就连续取消或关闭阀，使废气进入进气歧管。 An easy test for the diaphram is to remove the vacuum line that runs to the egr valve.一件容易的测试，为连续，是消除真空线运行到废气再循环阀。 You can normally reach the diaphram area with your finger.通常您可以达到连续区与您的手指。 Move this opposite from the direction it normally sits at.提出这项从对面方向，它通常位于。 Then cover the vacuum port located on the egr valve with a plugged hose or your finger.然后涵盖真空港口设于排气再循环阀与堵塞喉或您的手指。 The diaphram should either stay in this other position or slowly move to the normal position.该连续要么留在这的其他位置或慢慢移动到正常位置。 If it won’t hold vacuum and instantly returns to it’s origional position, either a vacuum port is still not plugged or the diaphram is leaking.如果它不会举行真空并立即返回到它原来的立场，无论是真空的港口仍是未插入，或连续泄露。 If it is leaking replace the egr valve.如果是漏水，更换废气再循环阀。 If the egr valve holds vacuum then remove the valve from the manifold.如果废气再循环阀的真空举行然后删除该阀从多方面的。 (Full Article) （全文）
