Abstract
The development of a modern high-speed, energy-efficient and reliable diesel engine requires high-quality lubrication of all friction parts in general and parts of the cylinder-piston group (CPG) in particular. The relevance of this research is due to the insufficient study of the process of oil jet supply of CPG parts, implemented in combined lubrication systems of modern high-speed four-stroke engines and significantly affecting the processes of friction, wear and scuffing of parts of this group. The analysis of previously performed works in this area has shown the feasibility of not only setting up an experiment, but also using computational modeling in order to increase the informativity of the results obtained. The aim of the study was to determine the coordinates of the point of ejection of the oil jet from the gap of the rotating connecting rod bearing. According to the accepted working hypothesis, the point of ejection of the oil jet was the geometric place of the maximum gap in the connecting rod bearing. To calculate the angular coordinate of this point, we used the method of composing and solving equations of plane motion of a solid body. As a result of the research, an analytical expression of the desired coordinate was obtained and its value was calculated during the working cycle for the conditions of the nominal operating mode of the research object - a high-speed universal air-cooled diesel engine 1CH 8.5/8.0 (TMZ-450D). Ensuring the reliability and increasing the accuracy of the results of the study is confirmed by comparison with the calculated data obtained by the method of classical dynamics of piston engines. The array of calculated values of the coordinate of the oil jet ejection point from the gap of the rotating connecting rod bearing of the diesel engine, defined in this paper, will be used for debugging the developed tool for calculating modeling of the oil jet feed process and subsequent optimization of the conditions of lubrication, friction and wear of CPG parts on this basis.
