Abstract

The chemical kinetics of cyclopentanone, an attractive fuel for spark ignition engines, was studied in a double-diaphragm, heated shock tube at pressures of 1, 6, and 8atm over the temperature range of 1105-1327K. A stoichiometric fuel-oxygen mixture with a fuel concentration of 0.1% was chosen to investigate the pressure, emission, and carbon monoxide time-histories during cyclopentanone oxidation. CO mole fractions were measured behind reflected shock waves with a continuous wave distributed feedback quantum cascade laser at 2183.22cm-1, with no interference from other intermediates. Measured values were compared to two recent chemical kinetic mechanisms. Models slightly under predict the rate and over predict the total concentration of CO formed during the exothermic process, over the entire temperature ranged investigated. However, at higher pressures, the modeled CO time histories for both mechanisms predict very well the amount of CO formed, and the rate at which it is produced.
