Air intake and exhaust pipe structure of automobile engine

Abstract

The invention discloses an air intake and exhaust pipe structure of an automobile engine; the air intake and exhaust pipe structure of the automobile engine comprises an air intake pipe connected withan air filter and an air exhaust pipe connected with a silencer; the air intake pipe comprises an air intake main pipe connected with the air filter, a three-port joint connected with the air intakemain pipe, an air intake branch pipe I connected with the three-port joint and an air intake branch pipe II connected with the three-port joint; the height of the opening of the air intake branch pipeII is higher than that of the opening of the air intake branch pipe I; a fan is arranged in the pipe of the air intake branch pipe I; the three-port joint comprises a first joining channel, a secondjoining channel and a third joining channel which are connected mutually; the first joining channel is connected with the air intake main pipe, the second joining channel is connected with the air intake branch pipe I, the third joining channel is connected with the air intake branch pipe II, and the junction of the second joining channel and the third joining channel is provided with a curved surface blocking piece. The air intake and exhaust pipe structure provided by the invention is capable of avoiding entering water in the engine effectively.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an intake and exhaust pipe structure of an automobile engine. Background technique [0002] A car is a non-track-bearing vehicle driven by power and having 4 or more wheels. [0003] It has been more than 100 years since the first automobile was invented, and automobiles have gradually entered the lives of the people; with the popularity of automobiles, many shortcomings of automobiles have become increasingly apparent; one of the many shortcomings is that once the automobile engine enters water, it will be seriously damaged. Especially in cities after heavy rain, there will be many car failures caused by engine water. [0004] Although there are already plans on the market to improve the wading ability of the car by setting two air intake ports, one high and one low, but the existing solutions all prevent water ingress by sealing the lower air intake port with a seal, but due to the ...

[0003] It has been more than 100 years since the first automobile was invented, and automobiles have gradually entered the lives of the people; with the popularity of automobiles, many shortcomings of automobiles have become increasingly apparent; one of the many shortcomings is that once the automobile engine enters water, it will be seriously damaged. Especially in cities after heavy rain, there will be many car failures caused by engine water

[0004] Although there are already plans on the market to improve the wading ability of the car by setting two air intake ports, one high and one low, but the existing solutions all prevent water ingress by sealing the lower air intake port with a seal, but due to the The air pipe will vibrate with the vibration of the engine, and the seal used to seal the air intake pipe is very easy to loosen, and the loose seal is likely to fail to seal completely. At this time, the external water can easily pass through the poorly sealed seal. into the engine, causing engine damage
