For the diesel cycle, heat input is given by the process of :

  • A.constant volume
  • B.constant pressure
  • C.constant temperature
  • D.Adiabatic

Answer: B

In the Diesel cycle heat is supplied at constant pressure.

The air standard Diesel cycle has isentropic compression, heat addition at constant pressure while the piston moves, isentropic expansion, and heat rejection at constant volume.

Constant volume heat addition belongs to the Otto cycle. Constant temperature heat addition belongs to the Carnot cycle, and the adiabatic processes are the compression and expansion strokes, where no heat is exchanged.
