Summary:

This paper redraws and shows the pressure volume Pv- diagram and the T-S diagram of the Carnot cycle, Otto engine, and turbocharged Zhou Engine. It imitates the thermodynamic analysis of steam or gas turbines, takes into account the transport-work, and rederives the ideal thermal efficiency formula of Otto engines, which is much different from the current one. It is found that the current thermodynamics of internal combustion (IC) engines neglected the transport-work and the entropy increase in the exhaust pipe, overvalued the ideal thermal efficiency, and is a wrong line in the temperature entropy (T-S) diagram. In particular, the entropy increase in the exhaust pipe hides and wastes a lot of mechanical energy, which the turbocharged Zhou Engine can recycle
