ANALYSIS OF THE EFFICIENCY OF RAPID-TESTS TO DETERMINE THE TIME TO REPLACE USED ENGINE OIL

Abstract

The article presents the results of the analysis of the effectiveness of express tests for monitoring the current state of engine oil during the period of its operation in an internal combustion engine and determining the limit state of used engine oil. The results of diagnostics by physicochemical, rheological and optical methods of changing the state of fresh motor oil from the lubrication system of a diesel internal combustion engine at regular mileage intervals are presented. A software product project is proposed in the form of a mobile application for diagnosing the state of engine oil in the lubrication system of an internal combustion engine based on paper chromatography using a drop test, which will allow individual motorists to determine the need to replace used engine oil and, as a result, increase the period services of tribocouplings of a motor vehicle and will increase their overhaul period.
