Problems connected with the circumferential distribution of compression ring pressure against the deformed cylinder wall during engine run were presented in this paper. In particular, division of the resultant force pressing the ring against the wall into component connected with ring own elasticity and the one originated from gas pressure was carried out and the influence of each force at individual phases of engine run was evaluated as well. The relationship allowing calculation of the circumferential ring pressure was also established. The paper contains figures and drafts obtained in a course of exemplary calculations of compression ring pressure concerning a running bulldozer engine. These figures show the areas of cylinder wall where so called light slots can appear. Conclusions resulting from the carried out simulation tests are discussed in Summary. The need for further investigations mentioned in presented study was shown as well.
