Original abstract
When using rotary motors such as a Wankel engine, gas leakage due to imperfect sealing between the rotor’s apex and the combustion chamber often occurs. The most problematic point in designing the sealing is the dynamic and the pressure load on the apex seal. The aim of this article is to describe the forces acting on the apex seal, which are necessary to know for the optimal design of the sealing mechanism. The investigation shows that the effect of the apex seal spring and force generated by this spring is significant for correct sealing of the rotary engine. In the future, we should try to find a way of designing the sealing mechanism based on the results of advanced simulations, which have not yet been created.
