A magnetic oil pan for automobiles

Abstract

The invention provides an automobile magnetic oil pan, and belongs to the technical field of engines. The automobile magnetic oil pan solves the technical problems that an existing oil pan is poor in scrap iron removal effect, cannot perform magnetization on engine oil and the like. According to the automobile magnetic oil pan, a magnetic layer is arranged on the inner wall of the oil pan, an oil baffle is arranged on the upper portion of the oil pan, and an antimagnetic structure used for shielding a magnetic field generated by the magnetic layer is arranged between the oil baffle and the bottom of the oil pan. The automobile magnetic oil pan has the advantages of being good in scrap iron removal effect, can perform magnetization on engine oil and the like.

Description

technical field [0001] The invention belongs to the technical field of engines and relates to an automobile magnetic oil pan. Background technique [0002] The oil pan is located at the lower part of the engine and can be disassembled to seal the crankcase as an oil storage tank. The oil sump is the lower half of the crankcase, also known as the lower crankcase. Its function is to close the crankcase as the outer shell of the oil storage tank, prevent impurities from entering, and collect and store the lubricating oil that flows back from the friction surfaces of the engine. Part of the heat prevents the lubricating oil from oxidizing. [0003] At present, more than 90% of the main working parts of the engine, such as crankshaft, camshaft, rocker arm, piston ring and various bearings, are made of ferrous materials. When the engine is working, these moving parts will inevitably wear and tear, and the metal debris produced by the wear will circulate with the oil, causing con...

AI Technical Summary

Problems solved by technology

When the engine is working, these moving parts will inevitably wear and tear, and the metal debris produced by the wear will circulate with the oil, causing continuous wear to the engine and seriously affecting the service life of the engine parts

As an oil storage device, the oil pan is also the flow center of the entire oil cycle, and most of the debris is brought to the oil pan by the oil circulation; the existing technology generally adopts the adsorption of magnetic oil drain bolt gaskets or oil filter elements However, these two technologies have the following three disadvantages: 1. The better the filtering effect is, the better the filtering effect is by relying solely on the oil filter to absorb the metal debris in the oil, that is, the debris adsorbed on the filter element The more debris, the poorer the oil passing ability; 2. When the filter paper absorbs too much and the oil pressure is too high, when the bypass valve is opened, the oil flowing into the engine through the bypass valve will not be filtered, and it will easily be filtered by the filter element. 3. The area of ​​the oil pan is relatively large. When the oil falls back to the oil pan, the probability of metal debris touching the magnet at the oil drain bolt is small. Most debris contained in the oil does not filter

[0005] In the patent [CN201218122Y], a magnetic bolt for an automobile engine oil pan is disclosed, which includes a magnet and a bolt seat, and the magnet and the bolt seat are connected to each other through an anti-magnet body. The positive fit connection can achieve the technical purpose of reducing costs and improving strength, but it is impossible for all iron filings in the oil to pass through the magnetic bolts, resulting in incomplete cleaning of iron filings
