Reducing Emissions (EGR) System: Purpose The exhaust-gas-recirculation (EGR) system reduces harmful NOx emissions that contribute to air pollutions by recirculating exhaust gas back through the intake manifold into the engine. There, it acts as a cooling agent to lower combustion temperatures. All this is done with the intention of preventing mono-nitrogen oxides (NO and NO2)
