EGR, commonly known as an exhaust gas recirculation system, is the purification device for the nitrogen oxides NOx that is one of the hazardous gases exhausted by the engine. Due to this system, a small amount of exhaust gas generated by the truck EGR engine will go back to the cylinder to delay the combustion process. The total flow of exhaust gas is decreased so that the nitrogen oxides are reduced in the end. Then the emission standard is improved.

Product Features
  1.Low Cost 
This truck EGR engine gets some slight changes based on the   China II emission standard. The versatility rate of its parts exceeds   95%. The fuel injection system is similar to the inline pump that is   consistent with the China II standard, not sensitive to the fuel   products.
2. Low Fuel Consumption
  There are 7 small orifices for fuel injection with high flow   rate ranging from 1200 to 1400ml/min. This product gets the fuel   atomized thoroughly and optimizes the timing performance of the intake   valve. At the later stage of the intake stroke, the valve will be closed   for getting the air in the cylinder expanded to reduce the temperature   of the inner air properly, as well as the maximum combustion   temperature. This is the working process of Miller Cycle Theory. 
Through the EGR system in the cylinder, the inert gas is increased in the cylinder to inhibit the generation of NOx. Due to the inner EGR and Miller Cycle technology, the flow rate of the intake air is reduced, the combustion at low air fuel ratio comes true and the emission is decreased successfully.
3. Low Maintenance Cost
  This truck EGR engine is same as the diesel engine of China II   standard in several aspects, such as the operation, repair and   maintenance.
