High-efficiency hybrid cycle

The high-efficiency hybrid cycle (HEHC) is a new 4-stroke thermodynamic cycle combining elements of the Otto cycle, Diesel cycle, Atkinson cycle and Rankine cycle.^[1]

HEHC engines

The 3rd generation design of the Liquidpiston Engine currently in development is the only engine currently designed around the HEHC. It is a rotary combustion engine.^[2]
