Abstract
An engine cycle simulation which included the second law of thermodynamics was used to examine the engine performance and the thermodynamic characteristics of a spark ignition engine as functions of the oxygen inlet concentration. A wide range of oxygen inlet concentrations (12% to 40% by volume) was considered. For oxygen inlet concentrations less than 21%(v), EGR was used, and for oxygen inlet concentrations greater than 21%(v), oxygen enriched inlet air was used. Two EGR configurations were considered: (1) cooled and (2) adiabatic. In general, engine efficiencies decreased, heat transfer increased, nitric oxide emissions increased, and the destruction of availability (exergy) decreased as the oxygen concentration increased.
