The issues of complex car design based on the latest achievements in material science, electronics and all kinds of applied applications in special software devices, which use elements of artificial intelligence and artificial neural networks in control and management systems, should be considered in combination with consideration of many important issues and first of all in relation to variants of power supply of normal engine operation, whether it is electric engine or any of the internal engine variants.At one time the invented variants of the rotary engine began to be put into practice, but the automobile manufacturers were not able to get any operational effect with such engines. More recently, research has been going on in the area of rotary engines operating according to the OTO thermodynamic cycle, which the author of this book wants to examine.
