a b s t r a c tIgnition delay times of dimethyl carbonate DMC were measured using low-and high-pressure shock tubes and in a rapid compression machine (RCM). In this way, the effect of fuel concentration (0.75% and 1.75%), pressure (2.0, 20, and 40 atm) and equivalence ratio (0.5, 1.0, 2.0) on ignition delay times was studied experimentally and by model ing. Experiments cover the temperature range of (795-1585 K). Several models from literature were used to perform simulations, thus their performances to predict the present experimental data was examined. Furthermore, the effect of the thermodynamic data of the CH 3 O(C = O) Ȯ radical species and the fuel consumption reaction CH 3 O(C = O)OCH 3 CH 3 O(C = O) Ȯ + CH 3 , on the simulations of the ignition delay times of DMC was analyzed using the different models. Reaction path and sensitivity analyses were carried out with the final model to present an in-depth analysis of the oxidation of DMC under the different conditions studied. The final model used AramcoMech 2.0 as the base mechanism and included a DMC sub-mechanism available in literature to which the reaction CH 3 O(C = O)OCH 3 CH 3 O(C = O) Ȯ + CH 3 was modified. Good agreement is observed between calculated and experimental data. The model was also validated using available experimental data from flow reactors and opposed flow diffusion and laminar premixed flames studies showing an overall good performance. To this end, studies addressing the thermal decomposition [4-6] , 17 photolysis  and oxidation of DMC have been reported in the lit-18 erature. 19 Sinha and Thomson  measured species concentrations across 20 DMC/air and propane/DMC/air opposed flow diffusion flames.
