Problems solved by technology
The pressure of the gas discharged from the engine is usually the same, but when passing through the two exhaust pipes, due to the difference in design between the two, it will cause different back pressures when the gas circulates in the two exhaust pipes. The back pressure of the engine will cause the air pressure to be unbalanced, which will in turn affect the exhaust condition and power performance of the engine, and even affect the running performance of the entire car.

Embodiment Construction
[0013] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0014] Such as figure 1 As shown, the automobile exhaust pipe of the present invention comprises a left exhaust pipe 1 and a right exhaust pipe 2, and each of the left exhaust pipe 1 and the right exhaust pipe 2 has four air inlets 4, which are used to receive exhaust from the engine. gas.
[0015] The left and right exhaust pipes are close to each other in the middle until they touch and connect as a whole. The specific structure is as follows: figure 2 As shown, it is approximately X-shaped. The part where the two are in contact is provided with a hole 3 on the inner side wall of the left exhaust pipe 1, and the same hole 3 is also provided on the opposite side wall of the right exhaust pipe 2, as image 3 As shown, ...

The invention provides a car exhaust pipe, belongs to the field of car fittings, and solves the problem of affecting the normal operation of an engine due to the unbalanced return pressure of the traditional car exhaust pipe. The car exhaust pipe comprises a left exhaust pipe and a right exhaust pipe, wherein a communicating part for connecting the left exhaust pipe with the right exhaust pipe and communicating the atmospheric pressure in the left exhaust pipe and the right exhaust pipe is arranged between the left exhaust pipe and the right exhaust pipe. According to the car exhaust pipe, due to the arrangement of the communicating part, the gases in the left exhaust pipe and the right exhaust pipe can mutually circulate, so that the atmospheric pressure are the same, and the return pressure are also balanced. Therefore, the running state of the engine is prevented from being affected due to different return pressure.
Description
technical field [0001] The invention belongs to the field of auto parts, and relates to an automobile exhaust pipe, in particular to an automobile exhaust pipe with balanced air pressure at an air outlet. Background technique [0002] The exhaust pipe is a very common exhaust component on the car. Its air inlet is connected with the gas exhausted from the engine and discharged from the outlet of the exhaust pipe. Existing automobile exhaust pipes usually include a left exhaust pipe and a right exhaust pipe, both of which are independent and usually each have four air inlets for respectively receiving gases discharged from the engine. The pressure of the gas discharged from the engine is usually the same, but when passing through the two exhaust pipes, due to the difference in design between the two, it will cause different back pressures when the gas circulates in the two exhaust pipes. The back pressure of the engine will cause the air pressure to be unbalanced, which will...
