The EGR valve is a very important component of the exhaust gas recirculation device. It can return part of the exhaust gas from the engine to the intake manifold and re-enter the cylinder together with the fresh mixture.Not only can it reduce the temperature in the cylinder during combustion ,but also reduce the production of NOx.

The Ignition coil is the core technology of the ignition system.In order to make the engine run, the Ignition Coil will change the battery voltage 12V to the high voltage above 30KV .Then it will ignite the mixed gases in the cylinders by discharging between the spark plug gaps .
