Dual Combustion Cycle (also known as the limited pressure or mixed or Sabathe cycle) is a thermal cycle that is a combination of the Otto cycle and the Diesel cycle. Heat is added partly at constant volume and partly at constant pressure, the advantage of which is that more time is available for the fuel to completely combust. Because of lagging characteristics of fuel this cycle is invariably used for diesel and hot spot ignition engines.

The dual cycle consists of following operations:

1. Adiabatic compression
2. Addition of heat at constant volume.
3. Addition of heat at constant pressure.
4. Adiabatic expansion.
5. Rejection of heat at constant volume.
