There are two of the most interesting cars diagnostic technologies: tribodiagnostics and vibration diagnostics. The basis of tribodiagnostics is monitoring of wear of friction units on the analysis of wear of particles in lubricating system and quality control of lubricating oil during operation. Mechanisms and systems of internal combustion produce vibrations, and it is used in vibration diagnostics.
The main parameters of the diagnosis of cars, namely wear and engine oil quality control are: number of wear particles per unit of volume of grease and their chemical composition. The size and shape of the particles and their change in the course of operation, allow us to estimate the intensity and mechanism of wear that makes it possible to propose a number of recommendations to prevent the wear crash at a very early stage of their origin and development due to the high sensitivity of the methods and technical means.
