The fundamental problem with wide application of the Wankel engine is to assure oil film continuity on trochoidal cylinder bearing surface. For the sake of considerable difference between curvature radius of the apex seal sliding surface and the trochoidal cylinder the oil film can be generated on the short fragment of the apex seal. However there is certain field of maneuver in the apex seal shape determination which allows to approach close radiuses of curvature of both elements in the areas where the highest gas forces load is occurred. In the paper simulation of the revised apex seal oil film parameters are presented. Author described also the test stand which is going to be used for experimental verification of the simulation results. Conclusions refer to possibility of replacement the constant radius shape of the apex seal sliding surface with shape that consist of two different curvatures.
