Wankel rotary piston engine cycle: Analysis and calculation taking into account the composition of combustion products

The Wankel rotary piston engine has been known since 1956. It has been used in practice, e.g. by Mazda. It is still in use after correction of shortcomings, as it has undeniable advantages over the crank engine. It must be said that despite the large number of publications on the subject, it is difficult to find a reliable analysis of how to calculate it. The present paper outlines analysis and calculation of the Wankel rotary piston engine, as well as calculation of composition of combustion products at application of different fuels.
