The dual cycle is used to model a real engine because it

  • A.Removes the need for a compression process
  • B.Assumes no heat rejection at all
  • C.Adds heat by both processes
  • D.Adds heat only at constant temperature

Answer: C

Real combustion begins rapidly near top dead centre and continues as the piston descends, so neither idealisation alone fits. Splitting the heat addition between the two processes gives a closer match to the indicator diagram an actual engine produces.
