Abstract (English):
Based on the exact solution of the Navier-Stokes equations, pressure was calculated in the immediate vicinity of the comer point of the piston ring acting on the lubricant side, graphs of pressure versus distance from the comer point were plotted, and based on the calculations, recommendations were made to design organizations and ship mechanics on preventing breakages in comer pieces rings. In the review part, the topical issues of analysis of piston rings defects of ship diesel engines arising during operation are reviewed, materials on the arrangement of ship diesel engines and parts of the cylinder-piston group and drawings of these mechanisms and parts are presented, and an analysis of piston ring breakdowns has been performed.
