Description
Technical Field
The invention belongs to the technical field of internal combustion engines, and particularly relates to a distributed independent lubrication engine test device.
Background
The high temperature and high pressure generated by the cylinder cause each main part to be under high temperature and strong impact pressure. Therefore, cooling and lubrication become very important issues in engine operation. Although the cooling system can be responsible for a portion of the cooling task, the cooling of the moving parts is primarily undertaken by the lubrication system. The friction surfaces of each moving part of the engine are influenced by huge impact force, so that the difficulty of lubrication is increased, and the lubricating oil works under severe conditions.
In addition, the quality of the lubricating oil is constantly affected by other factors and varies. For example, fuel can be led into the lubricating oil through a certain channel to dilute the lubricating oil, thereby reducing the lubricating effect. After the carbon deposit adhered on the cylinder and the piston is mixed into the lubricating oil, the lubricating oil is polluted and deteriorated; sulfur oxides in fuel oil often form acids with water in the lubricant oil, degrading the lubricant oil; the metal particles ground by the friction surface of the part in motion must also enter the lubricating oil. Lubricating oil is continuously evaporated, diluted, polluted and combusted in work, and accurate oil product analysis is required. Passing engine tests is the most direct and accurate method for testing the actual cooling and lubricating effects of lubricating oil. And the method is also an effective method for evaluating and analyzing the friction and the abrasion loss of parts and the service life of lubricating oil by regularly collecting oil samples in the test process. However, in the conventional engine test device, the engine is used as a whole for examination, and the actual required lubricating oil quantity in a cylinder cover and a machine body cannot be accurately analyzed, so that the problems of over-lubrication or insufficient lubrication and cooling of the engine are caused. Therefore, it is required to develop a test device capable of accurately measuring the amount of lubricating oil and analyzing the amount of frictional wear based thereon.
