Mixed/Dual Cycle

Mixed/Dual Cycle

The dual combustion cycle (also known as the limited pressure or mixed cycle, Trinkler cycle, Seiliger cycle or Sabathe cycle) is a thermal cycle that is a combination of the Otto cycle and the Diesel cycle, first introduced by Russian-German engineer Gustav Trinkler. 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 T-s and P-V diagrams are given below:

The dual cycle consists of following operations:

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