This article describes the basic principles for determining the trajectory of the apex seals of Wankel rotary engines. An attempt is made as the Wankel engine seems to be the convenient as the burning hydrogen fuel engine. The main advantage is particularly intensive cooling. The main disadvantage is high pollution of combustion gases. Analyzing the working constructions it is possible to find the main sources of pollution. After all it seems that specific work of rotating piston seals are the main reason of usage big volume of lubrication oil. But part of lubrication oil is burnt together with the fuel increasing the pollution. Even using hydrogen as fuel it remains difficult to meet EURO V regulations of combustion gases pollution made by transport vehicles. Every possibility of volume reduction of lubrication oil is important. In the article the trajectories of apex seals are discussed. As the mathematical model of trajectory a special formula of trochoid was chosen. The main advantages of the chosen form of mathematical equation are applications of two main parameters: curve size parameter and dimensionless curve parameter. These two parameters decided about convenience in changing volume of internal combustion engines and comparisons of performance characteristic of different Wankel engines. In other publications connected with Wankel motors more complicated mathematic formulas are still used.
