Applicable: Universal pressure relief valve, adjustable inside and outside the mixed diarrhea, according to the different use of different horsepower to adjust the spring damping strength, and can be transferred into a pure way of inner diarrhea, the use of a variety of methods for a variety of horsepower and models. Suitable for models with turbocharger, other models without turbocharger installed no effect. Product Description: All turbocharged engine will produce this sound, but for the daily civilian car, the manufacturers will design the sound as a noise to deal with, as much as possible to reduce it. The practice is to discharge the pressure into the intake manifold, so the noise is very small – this type of relief is called the vent type. When we step down the accelerator pedal to accelerate, the throttle valve opens, the engine will be issued with the speed of the lift issued “grace … …” sound, the engine exhausted high temperature and high pressure exhaust energy to promote the exhaust turbine rotation, when the turbocharger work (That is, when the turbine is rotated at more than 100,000 revolutions per minute), the turbocharger will compress the surrounding air to increase the engine intake air and increase the engine’s power. When we get the oil, the throttle opening quickly decreases until it is in the idle state, that is to say the engine does not need to enter the air, or the air in the intake pipe will be blocked in the throttle. But at this moment the turbocharger did not stop working! Due to inertia, the turbocharger is still kept at a speed of more than 100,000 revolutions per minute. It is now conceivable that the air will continue to be continuously compressed into the intake pipe at this time, and if the high pressure air in the intake pipe can not be discharged in time, the pressure in the intake pipe will rise rapidly, Valve damage or intake pipe burst. In this case, it is necessary to install a pressure relief device in the intake duct to remove the excess high pressure air from the intake turbine after compression. In fact the relief valve is installed in the intake pipe on a valve, used to control the boost pressure. The opening and closing of the relief valve is controlled by an electromagnetic coil operated by an ECU (electronic control unit). ECU will be based on the pressure of the turbine outlet pressure to make judgments, once the pressure exceeds the critical value, it will be on the electromagnetic coil power or power control, thus opening or closing the relief valve. When the pressure relief valve is closed to ensure that the intake pipe has enough intake pressure as the basis, when the valve can open the excess gas to the atmosphere, reduce the pressure inside the inlet to protect the engine intake pipe. So we heard the modified car “bared, bared” sound is the pressure relief valve in the pressure when the exhaust gas.
