What is the function of automobile exhaust pipe valve?

The exhaust valve is an indispensable auxiliary component in the pipeline system, which is widely used at the highest point or elbow of the pipeline or where there is closed air to remove the gas in the pipeline, dredge the pipeline and realize normal work.

From the appearance, the overall mechanism design is like a simple throttle valve, on which a butterfly valve and a vacuum actuator can be seen. The valve can be opened and closed by the suction of engine vacuum. As long as the valve is installed in the proper position in the exhaust pipe system and the switch timing is used correctly, the engine can have balanced torque and horsepower performance.

The principle of the system:

A variable valve is arranged in the exhaust pipe. When the rotating speed is low, the valve will be closed, so that the air flow can be discharged from a smaller diameter position or a single pipeline, so as to maintain the back pressure in the exhaust pipe and prevent the loss of torque at low rotating speed. At high speed, the valve will open, and the exhaust gas will be directly discharged through the large-diameter position or double pipelines, so that the exhaust gas can be discharged through more channels and outlets, and then the back pressure in the exhaust pipe will be reduced, and the continuity of horsepower will be more ideal.
