an oil filter

Abstract

The invention discloses an engine oil filter. The engine oil filter comprises a shell body. The shell body is divided into a first cavity, a second cavity, a third cavity and a fourth cavity, wherein the first cavity, the second cavity, the third cavity and the fourth cavity are communicated in sequence. The shell body is connected with an oil inlet pipe and an oil output pipe. The oil inlet pipe is communicated with the first cavity. The oil outlet pipe is communicated with the fourth cavity. A primary strainer is arranged in the first cavity. A first separator, a second separator and a filtering body are arranged in the second cavity. The first separator and the second separator are respectively of a conical pipe shape. The first separator and the second separator are arranged in the second cavity in a spaced mode, so that the inner portion of the second cavity is divided into a filtering cavity, a separation cavity and a sediment cavity. The filtering body is arranged in the filtering cavity. An oil inlet of the second cavity is arranged in the entry position of the side face of a column section of the separation cavity. A filter element is arranged in the third cavity. A permanent magnet is arranged on the side wall of the fourth cavity. The engine oil filter is high in filtering performance, and capable of well filtering out impurities in oil in a relatively complete mode. By the adoption of the engine oil filter, the engine oil does not need to be replaced until the running distance is 100000km.

Description

technical field [0001] The invention relates to an engine oil filtering device, in particular to a filter for filtering lubricating engine oil for automobiles. Background technique [0002] After the lubricating oil of the engine has been working for a period of time, there will be metal shavings and other impurities generated by the friction of engine parts; in addition, there will be foreign impurities, such as dust in the air entering the crankcase through the breathing pipe, fuel filler, etc.; and engine oil The colloids produced by itself, the products of the oxidation process of the engine oil itself, such as various organic acids, coke pitch and carbides will enter the lubricating oil passage with the engine oil. These impurities will promote the wear of parts, corrode parts or seize moving parts. Therefore, an oil filter must be added in the lubrication system of the engine to filter out the above-mentioned harmful impurities present in the oil, protect the main eng...

Problems solved by technology

[0003] However, most of the existing oil filters have defects such as poor filtering effect and inability to completely remove impurities in the oil, which need to be further improved
