It helps reduce the amount of the nitrogen oxides nox in the exhaust gases.
Exhaust gas recirculation system in automobiles.
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.
The exhaust gas recirculation system recirculates a part of the exhaust gas back into the engine cylinders through the combustion chamber.
One of the obd ii trouble codes related to egr is code p0402.
Just like any other car part or any other system in your engine there may be faults that prevent your egr from working properly.
What is an egr system.
Exhaust gas recirculation is the technique used for reducing the nitrogen oxide in both the internal combustion diesel engines as well as petrol engines.
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.
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.
This helps lower your engine s combustion temperature for a reduction in oxides of nitrogen nox emissions.
Benefits of exhaust gas recirculation egr.
The exhaust gas recirculation or egr system is one of several vehicle emission control systems.
