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.
Exhaust gas recirculation system in automobiles.
Although system designs vary the heart of nearly all egr systems is the egr valve.
What is an egr system.
Benefits of exhaust gas recirculation egr.
It helps reduce the amount of the nitrogen oxides nox in the exhaust gases.
An egr system is important because it reduces emissions by allowing burnt exhaust gas to flow back into the engine.
Exhaust gas recirculation is the technique used for reducing the nitrogen oxide in both the internal combustion diesel engines as well as petrol engines.
One of the obd ii trouble codes related to egr is code p0402.
The egr or exhaust gas recirculation system helps moderate a vehicle s nitrogen oxide emissions by lowering combustion temperatures.
While it plays an important role in reducing your car s toxic emissions a faulty erg valve may significantly reduce your car s performance.
One of these systems is the exhaust gas recirculation system and specifically the egr valve.
This helps lower your engine s combustion temperature for a reduction in oxides of nitrogen nox emissions.
The exhaust gas recirculation or egr system is one of several vehicle emission control systems.
Thanks to the evolution of technology some components were significantly improved with time.
