A method for measuring engine lubricating oil consumption value

Abstract

The invention provides a method for measuring the lubricating oil consumption value of an engine. The method involves a gas supply module, an oil mist main generating module, an oil mist collecting module and an oil mist analyzing and measuring module. The gas supply module is a power output module involved in the method, gas output by the gas supply module enters the oil mist generating module, and lubricating oil conveyed by an oil conveying pipe is changed from the continuous liquid state to the particle state and then enters the oil mist collecting module. A glass slide is arranged at the outlet of the oil mist collecting module so that particle oil mist small in size or flowing velocity on the glass slide can be analyzed and measured. The lubricating oil consumption characteristic can be judged according to the final experiment result, and the lubricating oil consumption value under a certain working condition is calculated; in addition, the lubricating oil consumption value under an unknown working condition can be predicted according to the consumption characteristic of lubricating oil, and the lubricating oil supply amount of the engine is preset.

Description

technical field [0001] The invention relates to a method for measuring engine lubricating oil consumption value, which belongs to the field of engines. Background technique [0002] During the working process of the engine, the use of lubricating oil is essential. On the one hand, the lubricating oil can take away the heat generated by certain parts during the transportation process; on the other hand, and the most important aspect, the lubricating oil can separate two parts that are moving relative to each other through the bearing capacity of the oil film. to reduce friction loss. However, there are not many studies on the properties of lubricating oil in the process of engine operation, and it is impossible to make a reasonable prediction of the engine lubricating oil consumption value fundamentally, which greatly increases the engine during the working process due to slippage. Insufficient oil supply causes scuffing of the cylinder or excessive oil supply causes a larg...

Problems solved by technology

Although the methods mentioned above can play a certain role in the research of lubricating oil consumption, the theoretical calculation in the laboratory stage is separated from its own working environment, and cannot comprehensively analyze the lubricating oil consumption.

Moreover, the analysis method of the test bench often requires a real vehicle or ship to work continuously for more than 20 hours, which consumes a lot of manpower, material resources, and financial resources for a real car or ship.
