The object is a finishing treatment technology of the ICEs parts; the aim - the improvement of the operational characteristics of ICEs; methods - the system analysis of the processes taken place in the contact zone being under abrasive treatment; Dron - 2, Neofot - 21, REM - EVM, ARS - 4, a microanalyser "Camebax", a profilograph - a roughness indicator PMT - 3, Reotest - 2; theoretical and practical results - an important scientific problem based on the interaction of the abrasive tools with treated surface and a layer "lubricating and cooling technological fluid + dispersion products" is solved; analytical dependences forecasting the quality of the surface layer, removal of metal, roughness and treatment time for obtaining necessary data depending on the qualities of the abrasive, lubricating and cooling technological fluid are defined; they are offered new compositions of the abrasive instrument, pastes and LCTF with perfected feature, and are given practical recommendations for their industrialintroduction that provides: increasing to longevity of the details ICEs on 10 - 15 %; increasing to capacity finish operation details ICEs on 10 - 15 %; the reduction to prime cost of the fabrication abrasive instrument, pastes and LCTF at the average in three times; innovation - a generalized model of different methods of abrasive finishing treatment for analytical defining the influence of composition and qualities of lubricating and cooling technological fluid on the technological system efficiency is suggested for the first time; the abrasive treatment method based on lubricating and cooling technological fluid containing silicon is proposed; in comparison with existed methods our generalized approach ensures the formation of the surface film with shear modulus of treated material resulted in the formation of dislocation structures with cold-work hardening metal and improvement of parts' operational characteristics; analytical solution of two surfaces interaction problem divided by a layer "lubricating and cooling technological fluid + dispersion products"; the worded recommendations on the further development got in work scientific and practical result; introduction - "1-st Donetsk Car Repair Plant", "Gorlovsky Car Repair Plant", "Stirol", "Santarm" (Russia); field of application - machine building, repair and instrument manufacture plants.
