Engine air filter

Abstract

The invention relates to the technical field of engine air filters, in particular to an engine air filter which comprises a filter element installation assembly and a filter element assembly, the filter element assembly is arranged in the filter element installation assembly in a sleeved mode, and the filter element installation assembly comprises a filter element installation sleeve. When air flow enters the inner cavity of the air velocity adjusting pipe and passes through the reserved annular flow guide cavity, the air flow can pass through the surfaces of the elliptic cylinders, and due to the fact that the elliptic cylinders are ellipsoids, the air flow passes through the surfaces of the elliptic cylinders and penetrates through the annular flow guide cavity, direct-current air flow can be blocked, the blowing direction of the air flow is dispersed, and the air velocity adjusting effect is improved. The heat dissipation effect of airflow is improved, when the airflow passes through the air filter, the dispersion range of the airflow is increased, the airflow is prevented from directly entering the inner cavity of the air filter, and through the arrangement, the exhausted air can be further filtered, so that the filter element can work more effectively for a longer time during use, and the service life of the filter element is prolonged. The period of replacing the filter element is avoided.

Description

technical field [0001] The invention relates to the technical field of engine air filters, in particular to an engine air filter. Background technique [0002] The air filter is a device that filters the impurities in the air through the filter element of the air filter. It is generally used in the filtration system of the engine. When the engine does power, it needs to suck clean air from the air filter, and mix the clean air and fuel in the engine. The combustion in the combustion chamber does work. If the air does not pass through the air filter element, the dust suspended in the air is sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. The main function of the air filter is to protect the cylinder, piston and piston ring of the engine, prolong the The service life of the engine is an important part of the vehicle.

AI Technical Summary

Problems solved by technology

[0003] When the engine sucks air into the air filter, the external air is quickly sucked into the air filter due to the huge negative pressure generated by the cylinder of the engine, and during the rapid flow of air, the high-frequency vibration generated by the air makes the air filter housing or The internal parts of the air filter resonate with it, causing the air filter to generate a lot of noise, and the heat generated by the engine is accumulated in the air filter, causing the temperature of the air filter to rise, which will affect the internal airtightness. The short passage distance makes the air flow directly into the engine, which will make the air flow entering the interior arrive quickly, so that the internal impurity removal effect is not good, and the flow control of the air flow is also very difficult
