This valve regulates the addition of a certain amount of exhaust gas to the incoming air.
This is necessary to reduce the combustion temperature of the fuel in the cylinders and reduce the content of nitrogen oxides in the exhaust gases.
The amount of exhaust gas added to the air is determined by the algorithm embedded in the CDI control unit (N3/9).
The EGR valve is located at the left rear of the intake manifold.
