Its main function is to redirect a portion of the exhaust gas from engine combustion back into the intake system for secondary utilization. The purpose of doing so is to reduce nitrogen oxide (NOx) emissions in the exhaust gas.

EGR Module is a combination of EGR Valves with Coolers

The EGR cooler is a component used to lower the temperature of the exhaust gases that are recirculated by the EGR system.

The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions.

Air Mass sensor is used to measure the flow of air entering the engine and monitor the amount of air required by the engine and provide accurate air flow information to the Engine Control Unit (ECU).

additional water pump transport coolant from the hot end of the engine block to the cold end, and dissipate heat through the radiator to maintain the engine operating within the normal temperature range.
