Problems solved by technology

Through the comparison of the test and test data, it is known that the resonant cavity and the 1 / 4 insertion tube do not improve the exhaust sound of the pressure relief valve, so the existing conventional air intake noise reduction methods cannot solve the problem of the exhaust sound of the pressure relief valve

Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see Figure 1 to Figure 3 , the exhaust muffler structure of the automobile pressure relief valve shown includes pressure relief valve exhaust pipe 3 and air filter outlet pipe 1. The interface 11, the other end of the exhaust pipe 3 of the pressure relief valve is used for fixed connection with the pressure relief valve, which is not shown in the figure. It also includes a muffler pipe 2 arranged in the exhaust pipe 3 of the pressure relief valve. The material of the muffler pipe 2 is die steel, which is low in cost and has a certain rigidity, which satisfies the operating conditions of the vehicle. The outer diameter of the muffler pipe 2 matches the inner diameter of the exhaust pipe 3 of the pressure relief valve. One end of the muffler pipe 2 facing the interface 11 is inserted into the interface 11, and the inner hole at the other end is a tapered hole ...

Abstract

The invention discloses an exhaust and noise elimination structure of a pressure release valve of an automobile. The exhaust and noise elimination structure comprises a pressure release valve exhaust pipe and an air filter air outlet pipe. A connector connected with one end of the pressure release valve exhaust pipe is formed in the air filter air outlet pipe. The other end of the pressure release valve exhaust pipe is used for being fixedly connected with the pressure release valve. The exhaust and noise elimination structure further comprises a noise elimination pipe arranged in the pressure release valve exhaust pipe. The outer diameter of the noise elimination pipe is matched with the inner diameter of the pressure release valve exhaust pipe. The end, facing the connector, of the noise elimination pipe is inserted into the connector, an inner hole in the other end of the noise elimination pipe is a conic hole with the diameter being gradually shrunk inwards from an end opening, and the angle of the conic hole is 45-75 degrees. The exhaust and noise elimination structure can reduce noise generated when the pressure release valve of the automobile exhausts air.

Description

technical field [0001] The invention relates to a muffler for an automobile air intake system, in particular to an exhaust muffler structure for a pressure relief valve of an automobile. Background technique [0002] As a high-efficiency, energy-saving and environment-friendly product, the turbocharged engine is becoming more and more popular. However, the noise problem of turbocharged engines is also becoming more and more prominent. When the turbo starts to work, it compresses a large amount of air and pushes it into the combustion chamber of the engine through the throttle body, but when the driver releases the accelerator pedal, the throttle closes, but the blades of the turbo will not stop working immediately. There is still residual compressed air in the intake pipe between the turbine and the throttle body. If this air is not discharged in time, the strong pressure will cause damage to the throttle body and the turbine blades, and when the accelerator pedal is steppe...
