Abstract
In this work, the performance of a standard air diesel cycle has been studied by using finite time thermodynamics along with determination of specific heat. The latter parameter has been determined as a function of temperature and compression ratio. Both output power and thermal efficiency at different cutoff ratios have been taken into consideration. The results show that, the power initially increased fast and reached to a maximum value at each cutoff ratio, followed by decreased with a slower rate and reached to a minimum value at each cutoff ratio. The maximum power was larger for smaller cutoff ratio. The maximum power and thermal efficiency were obtained 4.51 kW (for cutoff 1.3) and 0.61 (for cutoff ratio 1.5), respectively under reversible condition. The results can be used to design a real diesel with a high thermal efficiency and power. Index Terms— Diesel cycle, Friction, power, Thermal efficiency, specific heat
