NOTE:
Not all vehicles use EGR systems. EGR system usage depends on engine application.
The Exhaust Gas Recirculation (EGR) system distributes exhaust gas into intake mixture. This lowers combustion temperatures due to lower concentrations of oxygen. Lowering combustion temperatures reduces NOx emissions.
