Exhaust Gas Recirculation (EGR) System

The exhaust gas recirculation (EGR) system recycles a small amount of exhaust gas from the exhaust system and mixes it with the intake manifold air going into the combustion chambers. The addition of this inert (or non-combustible) exhaust gas limits the peak combustion temperatures to a range that is below 2500° F, where the formation of nitrogen oxide (NOx) is known to occur.


Key Component - EGR Valve

The exhaust gas recirculation valve (EGR valve) recirculates a portion of the exhaust gas back into the combustion chamber, which helps your vehicle produce fewer oxides of nitrogen, a major pollutant. More >>
