Abstract
Improving the reliability of tractor engines is an important task for the country's economy. The problem situation is a significant difference between the existing indicators of engine reliability and those possible with optimal parameters of the lubrication system. The aim of the study was to increase the reliability and durability of tractor engines by improving the prevention and tuning of the lubrication system. The paper presents the results of bench and operational studies of the developed oil level controller, as one of the options for tuning tools that provide the optimal oil level in the crankcase of an automotive engine. The intensity of oil aging and the reliability of the engine are largely determined by the frequency of refilling and changing the oil. As a result of the tests, it was found that the developed ROOM provides proportional compensation for the loss of oil from the crankcase. Comparative data on the performance of diesels with and without an oil level regulator are presented. According to the results of operational studies, their results largely confirm the results of experimental studies. A decrease in the intensity of changes in the technical condition of the crankshaft bearings, judging by the oil pressure, occurred by more than 20 %. The decrease in the intensity of changes in the technical condition of the cylinder-piston group, judging by the oil consumption for carbon monoxide, occurred by more than 50 %. The average temperature decreased by 2.5%, which reduced the intensity of aging of the oil and its resource increased by an average of 6.2-16.2 %. Based on the results of the comparison, conclusions are drawn on the effectiveness of this type of tuning of the diesel lubrication system.
