Diagnostics in place is used for on-the-go monitoring of internal combustion engine condition in tractors. When an engine is running, motor oil is continuously interacting with the engine processes, which is why change in motor oil quality is used as the criterion of such interaction. This research used two diagnostic methods: oil spectrometry to detect the content of wear products in used oil as well as the content of silicon, sodium, and metals from oil additives; and spot check to determine the total contamination of oil, its water content, and dispersancy. Studies found out the characteristic indicators of change in the engine’s technical condition. The authors were able to obtain dependencies that can be used to find out the diameter of additive diffusion spots, the radii of contamination / additive / pure oil zones. The paper establishes how oil quality correlates with the technical condition of the engine. A combined analysis of two oil and ICE assembly diagnosis methods produced the reference values for oil spot checks.
