摘要：

A simplified irreversible model has been proposed for the air standard Diesel cycle. Global thermal and friction losses have been lumped into an equivalent friction term. Optimization of the cycle has been performed for power output as well as for thermal efficiency with respect to compression ratio and cutoff ratio, The optimum values of these ratios compare well with standard values used in real Diesel engines. The cycle also demonstrates a loop-shaped power vs efficiency curve as is exhibited by real heat engines. (C) 2000 Elsevier Science Ltd. All rights reserved.
