Air filter for efficient engine

Abstract

The invention provides an air filter for an efficient engine. The air filter comprises a filter drum, a first end cover, a second end cover and a controller. An inner filter drum, a first filter element and a second filter element are arranged in a first cavity, the inner filter drum is arranged in the first filter element, and the first filter element is arranged in the second filter element. A second cavity is divided by the inner filter drum, the first filter element and the second filter element into a first filter cavity, a second filter cavity, a third filter cavity and a fourth filter cavity. An air inlet is communicated with the first filter cavity, and an air outlet is communicated with the fourth filter cavity. Filter holes are distributed in the inner filter drum, and a first detecting device for detecting the thickness of dust on the inner filter drum is arranged on the inner filter drum, and connected with the controller. A water guide pipe is arranged in the inner filter drum, spray heads are distributed on the water guide pipe, and flow valves are arranged in the spray heads. Water is sprayed through the spray heads, therefore, a large number of impurities in the air can be removed, and the inner filter drum can be cleaned and is prevented from being blocked; the air is filtered thoroughly, and the air supply needs of the engine are met.

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
