Can the egr valve of the fourth diesel vehicle not be used?

If you don't use the Pacific car network, it may affect the air intake at first, but it is not obvious. Second, if the high-temperature gas does not circulate for a long time, it may corrode or even break the EGR cooler and make the cooling water enter the cylinder, resulting in many problems such as white smoke and insufficient power.

Of course. After the egr valve is blocked, the exhaust volume of the engine will decrease, so the fresh air volume will increase. For the mechanical system, the power of the engine will be improved and it will be more fuel efficient.

Egr valve (exhaust gas recirculation valve) is a mechatronics product installed on diesel engine to control the amount of exhaust gas recirculation fed back to the intake system, which is called exhaust gas recirculation system.

It is usually located on the right side of the intake manifold, near the throttle body, and connected to a short metal pipe leading to the exhaust manifold. Its function is to control the amount of exhaust gas entering the intake manifold and make a certain amount of exhaust gas flow into the intake manifold for recycling. Egr valve is a very important and key component in exhaust gas recirculation device.

Egr valve can reduce the temperature of the combustion chamber, improve the working efficiency of the engine, improve the combustion environment, reduce the burden of the engine, effectively reduce the emission of NO compounds, reduce knock and prolong the service life of various components by introducing the exhaust gas discharged from engine combustion into the intake manifold.
