Investigations of oxygen-enriched and CO2 dilution combustion on the laminar burning velocity and auto-ignition for 'downsizing' engine application.

Résumé

The oxygen-enriched combustion has a great interest for industrial applications, since membrane separation technology can be achieved. One of the objectives of this work is to provide unique data of the laminar burning velocity for oxygen-enriched combustion of iso-octane/air mixture for varied dilution (by air or CO2) cases. The isooctane was mixed with a mixture of O2, CO2 and N2. The volume fraction of O2 was varied from 21% to 29% and CO2 was varied from 0% to 28%. By using detail kinetics mechanism with Senkin tool, auto-ignition delay was investigated for the same mixtures to get better understanding of the engine knock. Theoretically, with the increase of O2, the increase of laminar burning velocities prevents knock apparitions, meanwhile, the decrease of auto-ignition delay favourite knock events, inversely with the increase of CO2.
