EGR Valve (Exhaust Gas Recirculation Valve)

The EGR Valve (Exhaust Gas Recirculation Valve) is a system that controls the cars emissions. Specifically, it reduces NOx emissions.The way it does this is by retrieving a specific amount of exhaust that is being release back into the intake manifold(combustion chamber). Furthermore, it allows for the fuel to be completely burned and for the car to efficiently. The EGR valve is one of the most common causes for emissions testing. The car will have a rough idle and poor acceleration when the EGR valve begins to fail.The EGR valve is not something to be replaced like an oil filter, but needs to checked when it starts to fail.
