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.
Exhaust gas recirculation is the technique used for reducing the nitrogen oxide in both the internal combustion diesel engines as well as petrol engines.
The exhaust gas recirculation system recirculates a part of the exhaust gas back into the engine cylinders through the combustion chamber.
Just like any other car part or any other system in your engine there may be faults that prevent your egr from working properly.
An egr system is important because it reduces emissions by allowing burnt exhaust gas to flow back into the engine.
Benefits of exhaust gas recirculation egr.
Thanks to the evolution of technology some components were significantly improved with time.
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.
Although system designs vary the heart of nearly all egr systems is the egr valve.
The exhaust gas recirculation or egr system is one of several vehicle emission control systems.
What is an egr system.
It helps reduce the amount of the nitrogen oxides nox in the exhaust gases.
This helps lower your engine s combustion temperature for a reduction in oxides of nitrogen nox emissions.
