Construction of piston-rings-liner assembly of contemporary engines of low and medium power secures a long time reliable operation. In the case of engines of higher output, e.g. marine and railway ones still occur failures caused by improper collaboration of piston rings and cylinder liner. One can mention variations in collaboration surface and difficulties with supply and proper distribution of lubricating oil over the entire surface of cylinder liner among the most important ones. Changes in value of parameters characteristic for compression ring and cylinder liner collaboration that occur during engine run have been analyzed in the following study. Attention has been paid to the ability of ring contact with the liner, especially those features that cause the formation of light slots between ring face and liner surface. Drafts presented in the paper show the results of compression ring pressure distribution and the geometry of light slots carried out for technical data of the earth moving machine engine. Simulation computations take into account both the effect of engine operation cycle phase and selected stages of its run as well.
