Abstract

The invention discloses an air filter of an automobile engine, which is used for solving the problems that the volume of the air filter is large and the effective filtering area of a filtering core is small in the prior art. The air filter comprises an upper shell, a lower shell and the filtering core, wherein the outer side wall of the upper shell is provided with an air outlet of the air filter; the outer side wall of the lower shell is provided with an air inlet of the air filter. The air filter is characterized in that an airflow buffering belt is arranged between the upper shell and the lower shell; the filtering core is arranged in a cavity of the lower shell; the lower shell and the filtering core are respectively in a conical structure. The air filter disclosed by the invention has the advantages that not only can the filtering efficiency of the air filter be improved and can the NVH (Noise Vibration and Harshness) performances of a vehicle are improved, but also the distribution of an engine cabin of the vehicle is easy.

Description

technical field

[0001] The invention relates to an air filter, in particular to an air filter for an automobile engine, and belongs to the technical field of combustion engines. Background technique

[0002] The air filter is an important part of the automobile power system. Its main function is to filter air impurities, deliver clean fresh air to the engine intake system, reduce the wear of the cylinder, piston and piston ring, and prolong the life of the engine. With the enhancement of people's awareness of environmental protection, the current vehicle lightweight design has become one of the important measures for vehicle energy saving and emission reduction, and the layout of the engine compartment is developing in the direction of compactness. Therefore, not only Pay attention to its filtration efficiency, ensure sufficient air intake, and minimize the volume of the air filter.

[0003] as attached figure 1 As shown, the existing air filter housing is a split structur...
