A back pressure exhaust pipe capable of generating electricity

Abstract

The invention provides a back-pressure exhausting pipe capable of generating power, belongs to the technical field of automobiles, and solves technical problems that an existing back-pressure exhausting pipe is poor in back pressure effect, and energy of exhausted gas cannot be utilized completely. The back-pressure exhausting pipe capable of generating power comprises a front-segment pipe connected with an engine, a rear-segment pipe connected with a silencer, a first manifold and a second manifold. The inlets of the first manifold and second manifold are both communicated with the outlet of the front-segment pipe, and the outlets of the first manifold and second manifold are communicated with the inlet of the rear-segment pipe; an impeller is arranged in the first manifold and is connected to an engine, and a shutter capable of closing the inlet of the second manifold is arranged in the second manifold. The back-pressure exhausting pipe has the advantages of good back pressure effect, complete use of the energy of the exhausted gas and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an exhaust pipe, in particular to a back pressure exhaust pipe capable of generating electricity. Background technique [0002] The automobile referred to in this article refers to the automobile whose main output power is the internal combustion engine. It is discharged out of the car through the exhaust pipe, which not only wastes energy, but also has an impact on the environment. [0003] The main resistance in the exhaust pipe of a car comes from two aspects. One is the friction force of the inner wall of the exhaust pipe on the fluid. When manufacturing the exhaust pipe, it should be made into a shape with a smooth inner wall and the direction of the airflow. The pressure of the airflow in the trachea, the back pressure exhaust pipe is a kind of exhaust pipe that uses the airflow pressure to improve the exhaust performance of the car, thereby improving the characteristics...

AI Technical Summary

Problems solved by technology

[0005] In the patent (CN101612897A), a car with an electric drive device is disclosed, including a wind generator installed in the exhaust pipe. The wind generator adopts a permanent magnet generator, and its address is installed on the chassis of the car. There are several permanent magnets evenly distributed on the outer circle, and there are several wind blades inside the rotating shaft cylinder, which use the wind energy from the exhaust exhaust of the automobile to generate wind power, and then use the motor installed on the wheels to boost the car forward, but the wind power generation The device will hinder the exhaust of the exhaust pipe of the car, especially at high speeds, hindering the smooth flow of the exhaust air, which will cause the power and emission of the engine to deteriorate
