Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of internal combustion engine lubrication, and in particular relates to an auxiliary lubrication device for an internal combustion engine. Background Art
[0002] The internal combustion engine provides power support for the equipment and is the core assembly component of the equipment. Through practical application, it is found that the wear of the internal combustion engine follows a certain pattern. The wear pattern shows that the most serious wear period of the internal combustion engine is three minutes after the internal combustion engine is started and turned off. This is mainly because the lubricating oil on the body of the internal combustion engine returns to the oil pan under its own weight when the internal combustion engine is shut down. When the internal combustion engine is started, it takes about three minutes for the oil pump to suck the oil and press the lubricating oil to each friction surface. These three minutes are operated without good lubrication, which will aggravate the wear of the lubricating surfaces of the internal combustion engine. The wear during this period is the most serious. Similarly, when the internal combustion engine is turned off, the oil pump stops supplying oil to the lubricating surface of the body. At this time, due to the inertia, the crankshaft is still rotating. Under the action of inertia, the moving parts are delayed for about three minutes to stop. Working under high temperature and without lubrication, the amount of wear increases linearly. Utility Model Content
