Exhaust Gas Recirculation System In Automobiles

One of these systems is the exhaust gas recirculation system and specifically the egr valve.

Exhaust gas recirculation system in automobiles.

One of the obd ii trouble codes related to egr is code p0402. In internal combustion engines exhaust gas recirculation egr is a nitrogen oxide no x emissions reduction technique used in petrol gasoline and diesel engines egr works by recirculating a portion of an engine s exhaust gas back to the engine cylinders this dilutes the o 2 in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce. The exhaust gas recirculation or egr system is one of several vehicle emission control systems. While it plays an important role in reducing your car s toxic emissions a faulty erg valve may significantly reduce your car s performance.

Nitrogen oxides are normally formed in the process of combustion in the engine cylinders. It helps reduce the amount of the nitrogen oxides nox in the exhaust gases. Although system designs vary the heart of nearly all egr systems is the egr valve. An egr system is important because it reduces emissions by allowing burnt exhaust gas to flow back into the engine.

The egr or exhaust gas recirculation system helps moderate a vehicle s nitrogen oxide emissions by lowering combustion temperatures. What is an egr system. Thanks to the evolution of technology some components were significantly improved with time. Just like any other car part or any other system in your engine there may be faults that prevent your egr from working properly.

The exhaust gas recirculation system recirculates a part of the exhaust gas back into the engine cylinders through the combustion chamber.
