Abstract
The structural changes of the ultrafine compounds and removal of impurities and resins from the operating oils are necessary to increase the efficiency of the in-place repair of tractor engines under the action of the repair-recovery compounds, tribo-preparations. It was revealed as a result of the electron microscopy that the tribo-compounds consisting of molybdenum disulfide, cuprum, and phosphorus modifies its chemical composition, which decreases after being exposed to ammonium hydroxide. To neutralize the action of the oxidation products in the operating engine oil, carbonic acid diamide capable of enlarging the resins, asphaltenes, carbenes, and carboide dissolved in the oil is added into the tribo-preparation composition. Adding the structure lubricating composition to operating engine oil enlarges the impurities' particle size from 0.1–0.5 to 10–20 μm, so that they can be easily removed by the centrifuges included into the lubrication system of the combustion engine. According to the results of evaluation of the antiwear properties of the lubricating compositions consisting of the operating oil with the admixture of the unstructured and structured tribo-preparation, the reduction of the wear spot by 50% in favor of the latter is specified. The comparative bench tests of the repair and recovery compounds before and after structuring showed a high recovery effect of the second (structured) composition.
