Problems solved by technology

The temperature of the exhaust gas directly discharged from the automobile engine is extremely high, and it needs to be treated by the muffler and the purifier before being discharged. When these high-temperature gases flow through the purifier and the muffler, the temperature of the purifier and the muffler will rise sharply. It will greatly accelerate the oxidation rate of the internal components of the purifier and muffler, resulting in a reduction in the service life of the purifier and muffler

Embodiment 1

[0020] refer to Figure 1-2 , a kind of automobile exhaust gas pretreatment receiving pipe, comprising exhaust gas receiving pipe 1, the side wall of exhaust gas receiving pipe 1 is provided with chute 2, the inner chute 2 is sealed and slidably connected with spool 5, and the chute 2 is equipped with driving sled 5. The driving device for moving back and forth. The inner bottom of the chute 2 is provided with an exhaust hole 21. The exhaust hole 21 can facilitate the sliding plug 5 to move back and forth without hindrance. The side wall of the slide plug 5 is fixedly connected with a telescopic air bag 6, and the tail gas receiving pipe 1 is fixedly connected with a one-way liquid discharge pipe 7 and a one-way liquid return pipe 8 communicating with the telescopic air bag 6, and the one-way liquid discharge pipe 7 is connected with the one-way liquid return pipe 8. A liquid storage cylinder 9 is commonly communicated between the liquid return pipes 8 .

Abstract

The invention discloses an automobile tail gas pretreatment receiving pipe. The automobile tail gas pretreatment receiving pipe comprises a tail gas receiving pipe body, and a sliding groove is formedin the side wall of the tail gas receiving pipe body. A sliding plug is connected into the sliding groove in a sealed and sliding mode, and a driving device for driving the sliding plug to move backand forth is arranged in the sliding groove. An exhaust hole is formed in the inner bottom of the sliding groove. A telescopic air bag is fixedly connected to the side wall of the sliding plug, a one-way liquid discharging pipe and a one-way liquid returning pipe which communicate with the telescopic air bag are fixedly connected to the tail gas receiving pipe body, and a liquid storage barrel jointly communicates with the position between the one-way liquid discharging pipe and the one-way liquid returning pipe. By the arrangement of the driving device, the driving device is operated throughkinetic energy generated during tail gas emission, so that the sliding plug is driven to move back and forth in the sliding groove, and cooling liquid can circularly flow in one direction along the pipe. Therefore, the temperature of tail gas is reduced, and damage caused by high temperature to a purifier or a silencer is avoided.

Description

technical field [0001] The invention relates to the related technical field of auto parts, in particular to an automobile exhaust gas pretreatment receiving pipe. Background technique [0002] The exhaust system of a car often includes components such as air ducts, exhaust purifiers, mufflers, and exhaust pipes. The temperature of the exhaust gas directly discharged from the automobile engine is extremely high, and it needs to be treated by the muffler and the purifier before being discharged. When these high-temperature gases flow through the purifier and the muffler, the temperature of the purifier and the muffler will rise sharply. It will greatly accelerate the oxidation rate of the internal components of the purifier and muffler, resulting in a reduction in the service life of the purifier and muffler. Accordingly, this application document proposes an automobile exhaust gas pretreatment receiving pipe. Contents of the invention [0003] The object of the present in...
