The chemical kinetics of cyclopentanone, an attractive fuel for spark ignition engines, was studied in a double-diaphragm, heated shock tube at pressures near 10atm over the temperature range of 1173-1416K. A fuel concentration of 0.5% was chosen to investigate the pressure, emission, and carbon monoxide time-histories during cyclopentanone pyrolysis in argon. 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.
