Exhaust Gas Recirculation Operation and Diagnosis

Since exhaust gas does not burn, this lowers the combustion temperatures and reduces NOx emissions from the engine.

Exhaust gas recirculation is the dilution of the air/fuel mixture to control amounts of exhaust gas. Since exhaust gas does not burn, this lowers the combustion temperatures and reduces NOx emissions from the engine.
