Detection device for engine oil performance of engine

Abstract

The invention provides a detection device for engine oil performance of an engine, belonging to the technical field of measurement and solving the problems of single physical and chemical parameter and incapability of scientifically and rationally judging the quality of the engine oil existing in the conventional engine oil detection method. The detection device for the engine oil performance of the engine comprises a capacitive sensor for detecting capacitance of the engine oil, an infrared sensor for detecting clarity of the engine oil, a display unit for displaying a result and a processor, wherein the processor is electrically connected with all the capacitive sensor, the infrared sensor and the display unit and can be used for analyzing signals input by the capacitive sensor and the infrared sensor and transmitting an analysis and processing result to the display unit. The physical and chemical parameters such as viscosity of the engine oil, moisture, open flash point, acid value, iron content and n-pentane insoluble substance are effectively and comprehensively evaluated by the capacitive sensor and the infrared sensor of the detection device for the engine oil performance of the engine, so that the detection device has the advantages of complete detection parameters, scientific and rational method and accurate result.

Description

technical field [0001] The invention belongs to the technical field of measurement or testing, and relates to a method for measuring chemical or physical properties of materials, in particular to a performance detection device for engine oil. Background technique [0002] An engine is a machine that converts other forms of energy into another energy, usually chemical energy into mechanical energy. It is widely used in devices such as automobiles, generators and ships. [0003] Engine oil, that is, engine lubricating oil, can lubricate, clean, cool, seal, and reduce wear on the engine. The engine is the heart of the car. There are many metal surfaces that rub against each other in the engine. These parts move fast and the environment is poor. The working temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life. [0004] Obviously, it is very important to scient...

AI Technical Summary

Problems solved by technology

The above-mentioned devices may all be able to detect a certain physical and chemical parameter of the engine oil, but there are the following defects: 1. It is necessary to take a sample for detection, but it cannot detect the engine oil in the engine in real time or intermittently, so that the driver cannot know the quality of the engine oil in time, and there are still problems. Missed Oil Change Problems

2. The physical and chemical parameters of the detection engine oil are single, and the quality of the engine oil cannot be judged scientifically and reasonably
