Abstract

A phenomenological model based on the use of multiple zones is described and compared with other experimental and analytical work. This multizone model is used to examine the effect on emissions of increasing the oxygen concentration in the intake air of a compression-ignition, direct-injection engine. It is concluded that O₂-enriched air could only be useful if combined with other modifications such as auxiliary gas injection, split injection, and exhaust gas recirculation.
