Valve

A vehicle fitted with an exhaust gas recirculation (EGR) system benefits from lower combustion temperatures and reducing oxides of nitrogen emissions (NOx). Some exhaust gases are re-introduced through the EGR valve into the engine inlet manifold, with the effect of reducing the temperatures within the combustion chamber reducing emissions. What is EGR Cooling? To cool the temperature even further, and...

This article taken from Toyota GB explains what an EGR valve is, what it does and what happens when it fails. The common signs of failure include engine performance issues like decreased power and acceleration, rough idle, and the engine management light coming on forcing the car to drive in limp mode. This article explains everything you need to know about complete EGR valves...
