Buffering and dispersing device for large-displacement tail gas of automobile

Abstract

The invention discloses a buffering and discharging device for large-displacement tail gas of an automobile and relates to the technical field of automobile tail gas. The buffering and discharging device comprises a first exhaust box, a second exhaust box and a connecting pipe, and the first exhaust box and the second exhaust box are fixedly installed. First air outlet pipes are fixedly connectedto the two side faces of the first exhaust box correspondingly, and second air outlet pipes are fixedly connected to the two side faces of the second exhaust box. Due to the fact that a control switchand a diversion pipe are arranged, a gas flow meter is used for monitoring the flow of tail gas in the connecting pipe in real time, a controller is matched for starting a motor, then a closing plateis driven to move, the closing state of the diversion pipe can be changed, when the automobile generates much tail gas, the two exhaust boxes can be promoted to work at the same time, the tail gas isdispersed, the phenomenon that the content of impurities in the tail gas is too high, and the impurities are finally attached to the inner wall of an exhaust pipe is avoided, the exhaust pipe of theautomobile is protected, and therefore the service life of the exhaust pipe is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust, in particular to a large-displacement automobile exhaust buffering and dispersing device. Background technique [0002] Automobile exhaust is the exhaust gas produced by the use of automobiles. It contains hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. Exhaust gas not only directly endangers human health, but also has a profound impact on the environment in which human beings live. The sulfur dioxide in the tail gas has a strong pungent smell, and when it reaches a certain concentration, it will easily lead to the occurrence of "acid rain", cause soil and water acidification, and affect the growth of crops and forests. [0003] In the prior art, the speed of the engine speed will determine the exhaust emission of the vehicle. When the vehicle is running on the ro...

Sulfur dioxide in the tail gas has a strong pungent smell, and when it reaches a certain concentration, it will easily lead to the occurrence of "acid rain", causing acidification of soil and water sources, affecting the growth of crops and forests

[0003] In the prior art, the speed of the engine speed will determine the exhaust emission of the vehicle. When the vehicle is running on the road at high speed, the exhaust emission is usually more than that in urban areas, and most automobiles are usually equipped with only one Exhaust pipe, when the car is at high speed for a long time, the exhaust gas emitted is too much, which will cause the impurities contained in the exhaust gas to adhere to the inner wall of the exhaust pipe, thus affecting the service life of the exhaust pipe, and will also give People's driving poses a certain threat
