WebEGR stands for exhaust gas re-circulation. In addition to this, the EGR system has three important parts – the actuator solenoid, DPFE and EGR valve. The car manufacturers decide to create the EGR system so that the burned exhaust gas can easily flow back into the engine, especially when the EGR valve is widely open. WebA widely adopted route to reduce NOₓ emissions is Exhaust Gas Recirculation (EGR). This involves recirculating a controllable proportion of the engine's exhaust back into the intake air.
