External electric heating and slight impurity removing system for oil pan

Abstract

The invention discloses an external electric heating and slight impurity removing system for an oil pan and solves the technical problems of how to heat engine oil and slightly remove impurities in the engine oil safely and the like in the prior art. The external electric heating and slight impurity removing system for the oil pan comprises an external heating mechanism, through which the engine oil is heated safely, of the oil pan and a slight impurity removing system. The external heating mechanism comprises a sensor which senses the temperature of the engine oil, an ECU with a decision-making function and a decision-making executing mechanism. The slight impurity removing system comprises an electric heating wire which generates action of a magnetic field, an impurity collecting grooveand a drain hole. The electric heating wire has both heating and magnetic field generating actions. The external electric heating and slight impurity removing system improves the oil fluid temperaturelifting speed during cold start of an engine and adsorbs fine scrap iron to play a cleaning role. An existing engine mechanism needs not to be changed in a large scope, so that the implementing difficulty is reduced and the external electric heating and slight impurity removing system is safer.

Description

technical field [0001] The invention relates to the field of automobile engines, in particular to an engine oil pan. Background technique [0002] The oil pan is located at the lower part of the engine, and its function is to seal the crankcase as the shell of the oil storage tank, prevent impurities from entering, collect and store the lubricating oil flowing back from the friction surfaces of the diesel engine, and prevent the lubricating oil from oxidizing. In the cold winter area, due to the low temperature, the overall performance of the engine lubricating oil is reduced, and the gap between the parts is large, there is a large amount of mechanical loss when the vehicle is cold started, the parts are severely worn, and iron filings are easily generated, which accelerates the vehicle's speed. damage. [0003] After the engine stops working, the lubricating oil will flow to the bottom of the oil pan. At low temperature, its viscosity is high and its fluidity is poor, so ...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the above scheme is that the vehicle engine takes a long time to warm up and the heating speed is slow, resulting in waste of oil; the price of low-temperature and high-fluidity lubricating oil is relatively high, which increases the cost of use
