Air filter for automobile engine

Abstract

The invention provides an air filter for an automobile engine. The air filter comprises a filter body, a first filter element, a second filter element, a first end cover and a second end cover. A round partition plate is arranged in the filter body. The interior of the filter body is partitioned into a first cavity and a second cavity through the partition plate. The first filter element is arranged in the first cavity. The first cavity is partitioned into a first filter chamber and a second filter chamber through the first filter element. An air guiding pipe is arranged in the first filter chamber. The air guiding pipe comprises multiple U-shaped pipe bodies which are arranged in an equally-spaced manner. Any two adjacent U-shaped pipe bodies are connected through a semicircular bent joint. The U-shaped pipe bodies and the semicircular bent joints are each provided with ventilation holes. The first filter element comprises two cylindrical segments and a corrugated segment connecting the two cylindrical segments. The second filter element is arranged in the second cavity. The second cavity is partitioned into a third filter chamber and a fourth filter chamber through the second filter element. Air guiding holes enabling the second filter chamber to communicate with the fourth filter chamber are formed in the partition plate. According to the air filter, air is filtered through multiple channels; air filtering efficiency and filtering cleanliness are improved; and the air supplying requirement of the engine is met.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to an air filter for automobile engines. Background technique [0002] At present, most of the air filters of automobile engines use paper filters. There are many ways to maintain and remove paper filter elements, such as holding high-pressure gas at a 45-degree angle to remove dust in the paper filter. In this method, the filter element of the paper filter must be removed from the car, and the dust particles embedded in the depth of the filter medium cannot be cleaned out. It is inevitable that the filter element will fail early due to dust embedding, which will increase the fuel consumption of the engine. Thereby, the work of the engine is time-consuming and laborious, and the replacement cycle of the filter element is shortened, requiring frequent replacement of new filter elements. In the prior art, there are disadvantages such as difficult dust removal, time-consuming and ...

Problems solved by technology

In this method, the filter element of the paper filter must be removed from the car, and the dust particles embedded in the depth of the filter medium cannot be cleaned out. It is inevitable that the filter element will fail early due to dust embedding, which will increase the fuel consumption of the engine.

As a result, the work of the engine is time-consuming and laborious, and the replacement cycle of the filter element is shortened, requiring frequent replacement of new filter elements

The existing technology has the disadvantages of difficult dust removal, time-consuming and labor-intensive work, and high maintenance costs.
