Nonlinear automobile exhaust pipe with inner wall self-cleaning function

Abstract

The invention discloses a nonlinear automobile exhaust pipe with an inner wall self-cleaning function, and belongs to the field of automobile exhaust pipes. According to the nonlinear automobile exhaust pipe with the inner wall self-cleaning function, according to the internal shape of a nonlinear exhaust pipe body, auxiliary in-situ rotating frames and linear cleaners, and main in-situ rotating frames and bulk cleaners are correspondingly arranged in a linear area and a bent area inside the nonlinear exhaust pipe body respectively, when tail gas flows in the nonlinear exhaust pipe body, the auxiliary in-situ rotating frames and the main in-situ rotating frames are impacted through tail gas flow to rotate, and then the linear cleaners and the bulk cleaners are driven to carry out targetedcleaning on corresponding areas of the inner wall of the nonlinear exhaust pipe body respectively, so that particles attached to the inner wall of the nonlinear exhaust pipe body are comprehensively and effectively removed, the particles are discharged out of the nonlinear exhaust pipe body along with the tail gas flow, therefore the comprehensive cleaning process of the inner wall of the nonlinear exhaust pipe body is automatically achieved, and the normal exhaust process is ensured.

Description

technical field [0001] The invention relates to the field of automobile exhaust pipes, in particular to a non-linear automobile exhaust pipe with inner wall self-cleaning function. Background technique [0002] The automobile exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter for controlling the emission of engine pollutants is also installed in the exhaust system. The trachea generally includes a front exhaust pipe and a rear exhaust pipe. In terms of the role of the automobile exhaust pipe on the automobile body, it plays the role of shock absorption and noise reduction, and prolongs the life of the exhaust muffler system. Its main working principle is to divert the airflow through multiple channels. These diversions only see friction and collision with each other to gradually reduce the flow velocity of the airflow. Such repeated cyc...

Problems solved by technology

[0004] The composition of solid suspended particles in the exhaust gas is very complex and has strong adsorption capacity, which can adsorb various metal dusts, strong carcinogens, benzopyrene, and pathogenic microorganisms. Therefore, when the exhaust gas is discharged, the solid suspended particles in the exhaust gas It will also adhere to the inside of the exhaust pipe. Long-term accumulation will easily lead to the blockage of the exhaust pipe, thereby affecting the normal exhaust of the exhaust pipe. Moreover, the exhaust pipe of a car is generally non-linear, which belongs to the form of multi-channel shunting. The installation path on the surface affects its curvature, so it is more difficult to clean the particles on the inner wall
