Efficiency Curves comparing HEHC, Otto (typical for a gasoline engine) and Diesel thermodynamic cycles

The figure shown above was generated by calculating efficiencies of air-standard thermodynamic cycles. The efficiencies may also be expressed as the equations:
Using this analysis, the thermodynamic efficiency of the HEHC cycle is shown to be ~ 37% greater than Otto / Diesel cycles. Note, for a more in-depth analysis, please download our paper presented at the 2005 ASME conference on Internal Combustion Engines, from the Information page.



This high efficiency cycle can be implemented with the proposed LiquidPiston Engine Concept.
