List of old and new concepts of ICE thermodynamic improvements considering realistic limits of both mechanical and thermal stress and pollutant emissions, especially new concepts of combustion (HCCI-like), piston motion control, consequences of downsizing, possibilities of waste heat recovery and heat regeneration. Methods of simulation for conceptual optimization in hierarchy of procedures. Importance of transparency for conceptual approach. Computerized T-s diagram. References to methods of higher order of precision using 1-D, Q-D and 3-D models, modularized thermodynamics using GT Suite elements for unconventional engine cycles.Examples of results, considering limits of isochoric-like combustion, high levels of turbocharging, bottoming cycles for waste/heat recovery and heat regeneration assessment. Conclusions for further development.
