detailed description

In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The noise generated by the airflow in a certain section of the intake pipe is generally of a fixed frequency. The air intake system of automobiles is generally arranged in the front section of the engine compartment. Due to the layout and space constraints of the engine compartment parts, the intake pipes will have different lengths. In addition to a certain intake system design, a certain resonant cavity is used on the intake pipeline to eliminate certain frequency noises. This method can effectively avoid specific noise to a certain extent.

One end of the air conduit 3 is connected, and the other end of the rear air intake conduit 3 is connected to the intake port of the turbocharger.

Optionally, a corrugated pipeline 7 for preventing vibration is provided on the front intake duct 1 .

Optionally, three quarter-wavelength tube cavities 4 are also provided on the front intake duct 1 for eliminating frequencies in three different frequency bands.

Optionally, there is a resonant cavity 5 at the lower end of the middle air intake duct 2 for eliminating frequencies of different frequency bands, and the resonant cavity 5 is further divided into two cavities for eliminating noise of different frequencies.

Optionally, the front intake duct 1 , the middle intake duct 2 and the rear intake duct 3 are connected by clamps.

The embodiment of the utility model also provides an automobile, including the air intake pipeline as described above.

The foregoing is a preferred embodiment of the present utility model, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can be made without departing from the principle of the present utility model. Retouching should also be regarded as the scope of protection of the present utility model.
