Two constant volume and two reversible adiabatic process
Diesel cycle is called constant pressure cycle because the heat addition process in diesel cycle is done at constant pressure whereas petrol cycle is called constant volume cycle (Otto Cycle) as here the heat addition is done at constant volume. (Heat rejection in both the cycles is done at constant volume).
Constant volume cycle involves Two constant volume and two reversible adiabatic process.
