Diesel Cycle
The Diesel cycle is an ideal air standard cycle which consists of four processes:
- 1 to 2: Isentropic compression
- 2 to 3: Reversible constant pressure heating
- 3 to 4: Isentropic expansion
- 4 to 1: Reversible constant volume cooling
and cut-off ratio,
, as:
The thermal efficiency of an Diesel cycle with a perfect gas as working fluid is:

n=
= a constant depending on specific heat capacity
