Mazda EGR Valve
Mazda EGR valve is quite different from the EGR valve used in other vehicles including car, truck, SUV, etc. In Mazda car, the EGR valve helps in managing the ignition system and emission system quite well. But the primary job of the valve is to reduce NO from the tall pipe and prevent any ping in the engine. To a common man, it is basically an integral part of the emission and ignition system of the engine. In the older version of the Mazda models, the engine EGR valve is mechanical, but in the recent later models, the valve is an electronic one.
The EGR valve is located on the intake manifold and allows a certain amount of exhaust gas back into the engine. In that way, EGR valve plays a major role in reducing the unwanted engine emission and also the engine knock. It will ensure the smooth and proper running of the vehicle. If your vehicle is making frequent knocks, you can have a check of the EGR valve. To reduce the unwanted emission and engine knocks, you must not have a close EGR valve, as it is not good enough to serve that purpose.
