Description

technical field [0001] The invention belongs to the field of internal combustion engines, and in particular relates to an internal combustion engine cylinder simulation device and a control method. Background technique [0002] In modern industry, there is friction between any two contact surfaces. The friction will cause wear and reduce the working accuracy of the device. In severe cases, it will even cause machine damage. In order to reduce wear and heat and prolong the service life of the machine, it is necessary to Lubricant is added between the two contact surfaces to reduce friction. Fluid lubrication is the most common lubrication method. The two friction surfaces are completely separated by a layer of lubricating oil film of 1.5-2 microns. The friction is generated from the internal friction between lubricating oil molecules, which effectively reduces wear and improves working performance. Fluid lubrication is widely used in various fields. Gears, bearings, pistons ...

AI Technical Summary

Problems solved by technology

In the actual work project, the temperature and pressure in the cylinder are very high, the working conditions are harsh, and the load impact is strong, which will easily lead to thinning of the lubricating oil film. Too thin oil film will lead to direct contact between the piston and the cylinder wall, and the wear and heat will increase sharply after working for a period of time. Cause damage to the diesel engine; and when the oil film is too thick, it will reduce the bearing capacity of the equipment, making it unable to work stably, and in severe cases, it will cause oil leakage and severe energy loss
