EGR Valve Function & Effect

Function

Bringing moderate exhaust gas into cylinders to reburn, thereby decreasing the highest temperature in the cylinder and reducing emission of NOx. In order to ensure the normal operation and performance of the engine is not too affected, the amount of exhaust gas recirculation must be controlled according to the engine working condition.

Effect

Significantly reduces NOx output in the tail gas, helping vehicles meet stringent environmental regulations such as Euro 5, Euro 6, and China VI standards.
