Where is the exhaust gas recirculation check valve?

The exhaust gas circulation check valve is close to the throttle body on the right side of the intake manifold and connected with the intake manifold and the exhaust manifold. The opening of the valve is controlled by a vacuum tube to determine the amount of exhaust gas delivered to the intake manifold. Exhaust gas recirculation check valve is a mechatronics product installed on diesel engine to control the exhaust gas recirculation amount of intake system, and it is a very important and key component in exhaust gas recirculation device. The exhaust gas circulating check valve leads the exhaust gas discharged by the engine combustion to the intake manifold to participate in combustion, which reduces the temperature of the combustion chamber, improves the working efficiency of the engine, improves the combustion environment, lightens the burden of the engine, effectively reduces the emission of carbon monoxide compounds, reduces the knock and prolongs the service life of all components.
