How to judge the quality of car turbocharger bypass valve？
Turbocharger technology has long been perfected, and many cars today use turbochargers. For a turbocharger, there is a very critical component, and that is the supercharger bypass valve. So is the damage of the bypass valve of the supercharger harmful to the power? In fact, if the bypass valve of the supercharger is broken, it will do great harm to the power of the car.
Does the supercharger bypass valve damage the power?
jeopardize motivation. The primary function of adding a bypass valve is that the turbocharger bypass valve will open itself during fast and prolonged loads. At this time, part of the exhaust gas directly enters the exhaust pipe through the bypass valve, so that the working pressure of the exhaust gas will be reduced, and the turbocharger speed ratio will also be reduced subsequently. In other words, the primary function of the supercharger bypass valve is to control the working pressure of the exhaust gas.
If the supercharger bypass valve fails, the bypass valve will always be on and off. At this time, even if the working pressure of the exhaust pipe is not enough, part of the exhaust gas will directly enter the exhaust pipe without passing through the turbocharger, which will cause serious turbo lag, which is very harmful to the power output of the car engine.
How to judge the pros and cons of the supercharger bypass valve?
1. If the turbocharger intervention speed ratio of the car increases significantly, you must check whether the increase in the bypass valve is damaged. The supercharger bypass valve is very harmful to the power of the car;
2. According to the "vacuum pump gun", it can be checked whether the turbocharger controller is smoothly completing the work;
3. Use a pressure tester to detect the burden of turbocharger intervention and the working pressure when it is not intervened, and compare the detected information with the standard value. When the error is relatively large, it is confirmed that the bypass valve has a problem.
4. When there is a problem with the bypass valve, the light section of the engine detonation flashes. At this time, you can use a special computer to load the fault code.
