Problems solved by technology

However, the traditional engine test device cannot evaluate the engine as a whole, and cannot accurately analyze the amount of lubricating oil actually required in the cylinder head and body, resulting in over-lubrication or insufficient lubrication and cooling of the engine.

Abstract

The invention provides a distributed independent lubricating engine testing device. The distributed independent lubricating engine testing device comprises a dynamometer, an engine, an ECU, an upper independent lubricating system and a lower independent lubricating system. The dynamometer is connected with the engine. The engine is internally provided with an oil bottom shell, an engine body, a cylinder cover, a gas distribution mechanism and an engine valve cover sequentially from bottom to top. A pipeline at one end of the upper independent lubricating system is connected to the gas distribution mechanism, and a pipeline at the other end of the upper independent lubricating system is connected to the cylinder cover. A pipeline at one end of the lower independent lubricating system is connected to the engine body, and a pipeline at the other end of the lower independent lubricating system is connected to the oil bottom shell. The upper independent lubricating system and the lower independent lubricating system are both in signal connection with the ECU. According to the distributed independent lubricating engine testing device, the upper portion and the lower portion of the engineare separated, and the changes of the lubricating oil demands, the lubricating oil consumption amounts, the part frictional wear states and the lubricating oil quality of the upper portion and the lower portion of the engine along with the working condition and the operation time can be measured and evaluated more accurately and independently.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, in particular to a distributed independent lubricating engine test device. Background technique [0002] The heat load and mechanical load of the engine are relatively high when it is working. The high temperature and high pressure generated by the cylinder make the main components under high temperature and strong impact pressure. Therefore, cooling and lubrication have become very important issues in engine operation. Although the cooling system can undertake part of the cooling task, the cooling of moving parts is mainly undertaken by the lubrication system. The friction surfaces of the moving parts of the engine are affected by the huge impact force, which increases the difficulty of lubrication and causes the lubricating oil to work under very harsh conditions. [0003] In addition, the quality of lubricating oil is also subject to the constant influence of other factor...
