A high-efficiency engine air filter

Abstract

The present invention proposes an air filter for high-efficiency engines, which includes a filter cartridge, a first end cover, a second end cover, and a controller; The filter cartridge is set inside the first filter element, and the first filter element is set inside the second filter element. The inner filter cartridge, the first filter element and the second filter element divide the second cavity into the first filter cavity, the second filter cavity and the third filter cavity and the fourth filter chamber, the air inlet is connected to the first filter chamber, and the air outlet is connected to the fourth filter chamber; filter holes are distributed on the inner filter cartridge, and the first filter for detecting the thickness of dust on the inner filter cartridge is arranged on the inner filter cartridge The detection device, the first detection device is connected with the controller, the inner filter cylinder is provided with a water pipe, the water pipe is distributed with a nozzle, and the nozzle is provided with a flow valve. The invention can not only remove a large amount of impurities in the air by spraying water from the nozzle, but also clean the inner filter cartridge to prevent the inner filter cartridge from being clogged, thoroughly filter the air, and meet the air supply demand of the engine.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to an air filter for high-efficiency engines. Background technique [0002] In order for the engine to function properly, a large amount of pure air must be drawn in. If the substances harmful to the engine in the air (dust, colloid, aluminum oxide, iron oxide, etc.) are inhaled, the cylinder and piston components will increase the burden, causing abnormal wear, and even mixing with the engine oil, causing greater wear , resulting in deterioration of engine performance and shortened life. The role of the car air filter is to provide clean air for the engine to prevent the engine from inhaling air with impurity particles and causing wear and tear. [0003] At present, most of the air filter elements on the air filter used by the engine are composed of a sealing ring, an upper end cover, an outer protection net, a filter paper, an inner protection net and a lower end cover lamp....

AI Technical Summary

Problems solved by technology

[0003] At present, most of the air filter elements on the air filter used by the engine are composed of a sealing ring, an upper end cover, an outer protection net, a filter paper, an inner protection net and a lower end cover lamp. Most of the existing inner and outer protection nets are made of The most important thing is to weld the connection mesh or vertically bite the mesh. The mesh of this structure is easy to cause waste of raw materials when cutting, and cannot completely filter out the particles in the air. The efficiency is low. After long-term use, the impurities on the filter element Not easy to clean
