Diagnostics of the lubrication system and cylinder piston group of automobile diesel.

The problems of estimating the periodicity of engine oil replacement in high-powered internal combustion engines during operation. A principle possible is shown to estimate and predict variations of cleaning motor oil properties based on the analysis of the dynamics of variations in the level of oil in the crankcase of a diesel engine. Theoretical and experimental substantiations are given for the method of diagnosing the cylinder-piston group and engine lubrication system based on the parameters of the volume and viscosity oil in the engine crankcase.
