Oil filter anti-counterfeiting and service life diagnosis system

Abstract

The invention relates to an oil filter anti-counterfeiting and service life diagnosis system. The diagnosis system comprises a data acquisition subsystem, a data processing subsystem and a display subsystem, and is characterized in that the data acquisition subsystem comprises an oil filter differential pressure sensor, an oil temperature sensor and a rotating speed sensor, the oil filter differential pressure sensor is used for acquiring the oil pressure drop before and after an oil filter at an operating state in real time, the oil temperature sensor is used for acquiring the oil temperature before the oil filter at the operating state, and the rotating speed sensor is used for acquiring the rotating speed of an internal combustion engine at an operating state in real time; acquired oil pressure drop data is compared with an oil pressure drop standard threshold value at a corresponding operating condition, if the oil pressure drop data does not fall in an oil pressure drop standard threshold value range, a diagnosis result is fed back to the display subsystem and an alarm is given. The oil filter anti-counterfeiting and service life diagnosis system is complete in function, not only has a blocking alarm function, but also has a breakdown or leakage alarm function and a leakage alarm function.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an anti-counterfeit and service life diagnosis system for an oil filter. Background technique [0002] At present, the engine has moving parts such as pistons. Engine lubricating oil is used to reduce the friction resistance of these mechanical parts to prevent wear and tear. To keep the engine oil clean and protect the engine, the oil filter plays a vital role. Engine parts will wear and produce metal shavings during operation. When replenishing engine oil, fine dust and sand will also enter from the oil filling port. These metal shavings and dust will accelerate the wear of parts such as the crankshaft, bearings, cylinder liners and pistons in the engine. In addition, when the engine is running at high temperature, the engine oil produces glue-like organic matter due to chemical changes. These glue-like organic matter will stick to moving parts and increase resistance. In order...

AI Technical Summary

Problems solved by technology

[0004] The alarm devices or maintenance indicators in the prior art are either complicated in structure and require substantial modification of the existing filter device, or have imperfect functions and can only display the opening state of the bypass valve but cannot provide breakdown or leakage alarms and anti-counterfeiting functions. or frequent false positives

In short, not a good and accurate display of filter life status
