EGR Control Valve
The electronic EGR control valve is mounted between the EGR cooler and the exhaust line. It is a solenoid type valve that controls the amount of exhaust gas by the duty signal of the ECM calculated by the intake demand amount and the engine load. An Exhaust Gas Recirculation (EGR) system precisely controls the amount of exhaust gas recirculated from the exhaust manifold to improve fuel economy and ensure combustion stability.
