What is an EGR valve and how does it work?

The EGR valve plays a very important role in an automobile, both from the point of view of vehicle operation and from the point of view of the environment. How does this item work? Is it needed in the car? Check it out for yourself!What is EGR?
EGR is an exhaust gas recirculation valve, its name comes from the English word Exhaust Gas Recirculation. This is the element responsible for returning part of the exhaust gases to the intake system.This process aims to reduce the amount of oxygen in the air supplied to the combustion chamber in order to protect the environment. This reduces emissions of highly harmful nitrogen oxides, which is the result of lowering the combustion temperature of the fuel-air mixture and slowing down the entire process.How does the EGR valve work?
In engines equipped with an EGR valve, the exhaust and intake systems are connected by a narrow pipe that allows a small portion of the exhaust gases to enter the intake manifold. The EGR valve is part of the pipe and "decides" whether exhaust gases enter the intake system, when they do, and how long it will last.The new EGR valves are electromagnetically controlled, which means that they open smoothly, to any degree, and also regulate the proportion of exhaust gases that are directed into the combustion chamber at a given moment. The older models had pneumatic controls and, unfortunately, did not adjust the exhaust dose smoothly, but rather opened and closed.The engine control unit decides whether to open the EGR valve. The EGR system will be closed at idle and until the engine is loaded or reaches optimal operating temperature. It also won't open when the engine is under full load. Some of the exhaust gases will also return to the unit at low and medium loads, as well as in the range of medium RPM.EGR valve — how to check its operability?
The best way to check if the EGR valve is working correctly is to use the diagnostic device connected to the on—board computer when the engine check indicator lights up. This can be done at an auto repair shop. Beyond the initial welcome package, 1xbet provides ongoing rewards through various promotional codes.
