Where was the pressure reducing valve (bypass valve) of the automobile turbocharger taken?

The air inlet pressure reducing valve is also commonly called "air inlet pressure reducing valve". Installed on the intake pipe near the throttle, it is the original pressure relief device for most turbocharged engines when they leave the factory. Because the turbine is driven by exhaust power, the throttle is closed when it is closed during driving (such as gear shifting and medium braking). Turbine blades (compressor wheels) still keep rotating under the action of inertia. At this time, due to the truncation of the throttle and the continuous pressurization of the blades, the air pressure in the intake pipe (between the throttle and the turbine) will rise rapidly. In order to protect the supercharging system, when the pressure reaches a certain limit value, the intake bypass valve is opened to guide excess air (pressure) back between the filter and the turbine to realize the function of depressurization protection. ) other people's information
