Engine and magnetic filter thereof

Abstract

The invention discloses a magnetic filter for an engine. The magnetic filter for the engine comprises a shell body and an end cover installed on an opening of the shell body, an oil inlet duct and an oil outlet duct are formed in the end cover, a magnetic filter element which is used for attracting ferromagnetic impurities is arranged in an inner cavity of the shell body, a plurality of channels are formed in the magnetic filter element, one end of each channel is communicated with the oil inlet duct, and the other end of each channel is communicated with the oil outlet duct. Therefore, due to the fact that the magnetic filter is arranged, residual ferromagnetic impurities in engine oil can be completely removed, the cleanliness degree of the engine oil is improved, and the lubrication effect of the engine oil is ensured; meanwhile, due to the fact that the magnetic filter element of the magnetic filter is arranged in the shell body, the magnetic field produced by the magnetic filter element is shielded through the shell body, interference of the magnetic field on other electronic devices is avoided, and safety performance of a whole vehicle is improved. The invention further discloses the engine with the magnetic filter.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a magnetic filter for the engine. The invention also relates to an engine comprising the above-mentioned magnetic filter. Background technique [0002] During the operation of the engine, it is necessary to filter the impurities in the oil through the oil filter to avoid damage to the internal structure of the engine. [0003] Traditional engines generally use paper filter element oil filters, such as figure 1 As shown, the oil pumped out from the oil pan by the oil pump 11 enters the paper grid surface of the filter element from the oil inlet of the filter 12 at a certain pressure (0.3-0.4Mpa), and enters after being filtered by the filter element. The center pipe flows into the main oil gallery 13 of the engine from the oil outlet (ie the central threaded hole) to perform lubrication. When the engine is started cold, or the filter element is blocked, and ...

Problems solved by technology

[0006] However, in the actual use of the above-mentioned oil filter, since the magnet is installed on the housing, most of the magnetic field generated by the magnet is shielded by the metal housing, the utilization rate of the magnetic field is low, and the adsorption effect of ferromagnetic impurities is relatively poor; at the same time, During the driving process of the vehicle, with the vibration of the vehicle body, the magnet and the shell will continue to rub against each other, which will easily cause oil leakage or fall off of the shell, which will affect the service life; The operation of electronic equipment on the vehicle that poses a potential hazard to the normal operation of the vehicle
