Abstract

A computer analysis has been developed for studying the energy and exergy performance of an indirect-injection, naturally-aspirated diesel engine operating under transient load or speed conditions and covering the operating profile of both industrial and automotive engines. The model is validated at steady-state operation and incorporates many novel features for simulating the transient response and analyzing all of the engine availability terms. The analysis reveals via multiple diagrams how the exergy properties of the diesel-engine subsystems vary according to the engine cycles for various speed and load changes. The diagrams also show the current-speed response. In addition, the effects of operating parameters such as the intensity of the applied change or heat loss to the walls are described from first- and second-law perspectives.
