Description
Technical Field
The invention relates to the technical field of engines, in particular to an engine oil measuring dipstick and an oil pan.
Background
During operation of the engine, a large amount of scrap iron is inevitably generated due to friction and abrasion, and most of the scrap iron is mixed into engine oil. If these pieces of scrap iron are not separated from the engine oil but continue to be re-transported to the respective lubrication sites with the circulation of the engine oil, not only does lubrication function but also machine wear is accelerated. At present, people adopt a method of adding magnetic materials on certain parts to magnetically absorb and separate scrap iron in advance besides filtering and separating the scrap iron by using a filter so as to achieve the aim of purifying engine oil.
A dipstick is a component that is inserted into the oil in the crankcase (also known as the sump) of an engine to measure and monitor the amount of oil (known as the oil level). After the front part of the oil dipstick is wrapped with a layer of magnetic material, scrap iron can be separated from engine oil and magnetically attracted on the magnetic material at the front end of the oil dipstick. When the oil level of the engine oil is checked by extracting the oil scale, scrap iron magnetically attracted at the front end of the oil scale can be removed. The effect is better. However, since the cross section of the magnetic material is larger than the cross section of the dipstick itself, it is nearly as large as the diameter of the dipstick hole (in this case, the dipstick hole) into which the dipstick is inserted. In this way, when the oil scale with a large amount of iron filings magnetically attracted to the front part is pulled out, the iron filings attracted to the front periphery of the oil scale are scraped by the inner edge of the scale hole, and a part of the iron filings are inevitably scraped off and fall back into the engine oil (because the end is relatively small) except for a part of the iron filings pushed onto the end of the oil scale due to the attraction of magnetic force. The scrap iron falling back into the engine oil is gathered together to form a lump (because the scrap iron is magnetized and is attracted to each other). Once these clumped pieces of scrap iron re-enter the filter with the circulating engine oil, it is more likely to clog the filter. The engine oil supply required by engine lubrication is seriously insufficient, accidents are easy to occur, and the service life of the engine is shortened; if the problem of the oil supply amount is solved by increasing the oil pressure, the problem of parts such as a water tank, an oil pipe and the like is crushed.
