Problems solved by technology

If the air pressure fluctuates too much, it will affect the engine intake effect and increase the intake noise
[0003] At present, the traditional air filter is not designed with an adjustable cavity structure, which may cause excessive fluctuations in air pressure in the air filter housing, unstable air flow field, and even turbulent flow, which affects the intake air volume and further affects the engine. performance
In addition, excessive air pressure fluctuations will also generate large intake noise, which will affect the NVH performance of the vehicle.

Abstract

The invention relates to an air filter of an automobile. The air filter of the automobile comprises a lower shell, wherein the top of the lower shell is provided with an upper shell through a latch structure and a clip; a filter element is arranged in the upper shell and the lower shell; a partition is arranged at one end of the lower shell; an adjusting valve is arranged in the middle of the partition; and an adjustable cavity is formed between the partition and the lower shell. The air filter of the automobile is compact and reasonable in structure and is high in filtering efficiency; and by the adjustable cavity, the size of the whole air filter can be changed by adjusting the opening of the valve according to actual flowing speed of fed air, and the purposes of reducing air pressure fluctuation, improving the air feeding effect and reducing air feeding noise are achieved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a volume-adjustable automotive air filter used in a vehicle air intake system. Background technique [0002] As the main component of the automobile air intake system, the air filter is required to provide clean and dry air to the engine, with high filtration efficiency and without adding too much resistance to air flow. When the engine is running, the intake process is intermittent, which causes the air to vibrate in the air filter housing. If the air pressure fluctuates too much, it will affect the engine intake effect and increase the intake noise. [0003] At present, the traditional air filter is not designed with an adjustable cavity structure, which may cause excessive fluctuations in air pressure in the air filter housing, unstable air flow field, and even turbulent flow, which affects the intake air volume and further affects the engine. performance. In addition, exce...
