Know the engine editor to explain the small knowledge of turbo relief valve in detail

The reason why the pressure relief valve is a separate chapter is because this part has been mentioned a lot and said a lot. At present, due to the commonly used low-pressure method, the pressure relief valve is a crucial part of the output power of the engine. Through the control of the pressure relief valve, the same engine often has different output characteristics.

Controlling the working pressure of the engine is the core function

There are many theories about the function of the pressure relief valve to protect the throttle valve or turbine. However, some engines now do not have a throttle valve, of course, the protection of the throttle valve cannot be fully explained; as for the protection of the turbine, in fact, when the boost pressure is too large, the intake components and cylinder combustion must be affected first, so The protection of the turbo can only be regarded as an additional role.

In fact, pressure protection is the most basic element for all these working elements under pressure. The function of the pressure relief valve is to control the pressure in the intake pipe below the limit value, which not only takes into account the needs of the engine, but also the pressure range that the intake components can withstand.

Just like our pressure cooker, there are several safety valves on it. The first pressure cooker only had one safety valve, but it often happens that the pressure is too high and it explodes. Later pressure cookers added various other safety valves, and the current pressure cookers basically have more than 3 insurances.
