Exhaust Gas RECIRCULATION: Description

All models use exhaust gas recirculation to reduce exhaust emissions. Some of the exhaust gas from the engine is diverted before it enters the muffler. This gas is routed back into the intake manifold. An exhaust gas recirculation valve controls the exhaust gas flow to intake manifold. The exhaust gases introduced into the combustion chambers help lower the formation of oxides of nitrogen (NOx) during the combustion process.
