  This study presents an analysis of a quantum mechanical formulation of the
Carnot like cycle using diatomic molecules, i.e., the Morse oscillator, as the
working substance. The generalized model with an arbitrary one dimensional
potential is used to obtain the important performance parameters such as the
efficiency, the power output, and the optimal region of the engine by
considering well width L moving with a finite speed. The optimal efficiency,
the maximum power output, and dimensionless power ranges of the working
substance was also determined. The results obtained in this work are found to
agree with those obtained for similar engine but with different working
substance.
