EFFICIENCY AND COMPRESSION RATIO OF A FIN ITE-TIME DIESEL CYCLE

Within the context of finite-time thermodynamics, we propose a Diesel- cycle model. In this model, we consider instantaneous adiabats and we take all the cycle's time evolution as only ascribed to the isobaric h eating and the isochoric cooling processes. The results we obtain for the efficiency and the compression ratio of the cycle are in accordanc e with typical real values of these quantities. Our results improve th ose reported by H.S. Leff for the same cycle.
