BMW 2 Series EGR

EGR” stands for exhaust gas recirculation. When engine combustion temperatures near 2500°F, the formation of smog-producing nitrogen oxides (NOx) increases. Exhaust, however, is mostly composed of carbon dioxide (CO2), which does not burn. The function of the EGR valve is to recirculate small amounts of exhaust back into the combustion chambers of the engine in order to decrease the combustion temperature, thereby reducing the formation of smog-producing nitrogen oxides. EGR valves can malfunction by becoming stuck open or closed due to carbon build up. When an EGR valve malfunctions CO2 is reintroduced to the combustion chamber at the incorrect time or in incorrect amounts, which does not decrease the combustion temperature sufficiently enough to prevent the increase of NOx.
