Exhaust Gas Recirculation (Egr) Valve - SSANGYONG Rexton Y200 Manual

EXHAUST GAS RECIRCULATION
(EGR) VALVE
The Exhaust Gas Recirculation (EGR) system is the
device to lower the NOx (oxides of nitrogen) emission
level caused by high combustion temperature.
Because the combustion process of the diesel engine
always needs excessive air, the exhaust gas contains
large amount of NOx.
The EGR valve restricts NOx generation by recirculating
some amount of the exhaust gas into the combustion
chamber to reduce the combustion temperature.
But the recirculated gas results in reduced charging
efficiency of mixture so that the engine performance
drops down. Because of this fact, EGR valve is tuned
to operate in the area where oxidized substances are
generated much.
