Air filter of automobile engine

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 component of the automotive 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 extend the life of the engine. With the enhancement of people's environmental awareness, the lightweight design of the entire vehicle has become one of the important measures for vehicle energy conservation and emission reduction. The layout of the engine compartment is developing in the direction of compactness. Therefore, in the design process of the air filter, not only Pay attention to its filtration efficiency, ensure sufficient air intake, and minimize the size of the air filter. [0003] As attached figure 1 As shown in the figure, ...

AI Technical Summary

Problems solved by technology

In this patented technical solution, the first casing is designed to be conical in whole or in part. Compared with the existing cylindrical structure or square structure casing, it can effectively use the inner space of the engine compartment, making the engine compartment narrow The internal space is reasonably arranged; however, the patented technical solution does not involve the filter element structure, and only the use of a conical structure shell cannot solve the problem that the air filter is large in size and unfavorable for the layout of the engine compartment, and it is of great importance to improve the air filter. The filtration efficiency of the filter is powerless
