Abstract

The invention discloses a pressure relief system for an engine supercharger. The pressure relief system comprises a supercharger body and an intercooler, wherein one end of the supercharger body is provided with an intercooler gas inlet tube in a communication mode; the other end of the intercooler gas inlet tube communicates with one end of the intercooler; the other end of the intercooler is provided with an intercooler gas outlet tube in the communication mode; the other end of the supercharge body is provided with a gas inlet tube in the communication mode; a pressure relief valve is arranged between the other end of the gas inlet tube and the other end of the intercooler gas outlet tube; one end of the pressure relief valve is provided with a pressure relief valve gas inlet tube in the communication mode; and the pressure relief valve gas inlet tube is fixedly connected to the intercooler gas outlet tube through a fixing mechanism. According to the pressure relief system disclosedby the invention, the pressure relief valve is separated from the supercharger body, and the pressure relief valve is independently arranged between the intercooler and the supercharger body gas inlet tube, so that the pressure relief purpose can be realized, an after-pressing or before-pressing channel does not need to cast in the supercharger body, the inner wall of an outlet of a pressing shell is smooth, gas flow is smooth, and noises can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an engine supercharger pressure relief system. Background technique [0002] At present, superchargers are usually used in automobiles for the purpose of increasing the amount of gas charged, increasing power, improving economy, and improving emissions. After being pressurized by the supercharger, the air enters the cylinder of the engine for combustion. When the car suddenly closes the accelerator and slows down, the opening of the throttle valve becomes smaller, but the impeller of the supercharger has inertia and continues to run at high speed. The pipeline in front of the throttle valve There is a sudden increase in pressure. [0003] In the prior art, most of the pressure relief valve integrated superchargers are used. The pressure relief valve is integrated in the supercharger. The valve opens, and the high-pressure gas in the post-pressurization pipeline of t...
