Problems solved by technology

[0007] However, at present, the quality evaluation of engine oil mainly uses the physical and chemical indicators of engine oil, which cannot truly reflect the actual volatilization of engine oil during vehicle operation and the actual impact of volatilized engine oil on the engine, so it cannot accurately evaluate whether the engine oil is suitable for the application.

Abstract

The invention relates to an engine oil adaptability detecting method. The method comprises the following steps of: accessing an oil and gas separation device between a vehicle oil and gas separation system and an intake manifold; executing alternating load operation, wherein in the alternating load operation, the oil and gas separation device collects the engine oil discharged from the vehicle oiland gas separation system to the intake manifold; and determining whether the engine oil is suitable for the vehicle or not based on the collected engine oil amount. The engine oil adaptability detecting method can accurately evaluate whether the engine oil is suitable for an applied vehicle or not.

Description

Technical field [0001] The invention relates to a simulation test method and device for lubricating oil, in particular to a method and device for detecting engine oil adaptability. Background technique [0002] As a standard for comprehensively evaluating the quality of lubricating oil, countries around the world are basically in agreement and have established a quality standard system consisting of four parts: physical and chemical indicators of lubricating oil, simulation test, bench test and driving test. [0003] The physical and chemical indicators to measure the basic performance of lubricants include: kinematic viscosity, low temperature dynamic viscosity, viscosity index, flash point, pour point, high temperature and high shear viscosity, evaporation loss, sediment, moisture, foam, carbon residue, sulfate ash, Element content, etc. These physical and chemical indicators are just the most basic indicators for measuring lubricants. [0004] The simulation tests mainly include...
