| Research Abstract |
To construct the comprehensive reaction model that can predict the ignition timing in the homogeneous charge compression ignition(HCCI) engine cycles, ignition delay times(τ) were measured in a newly produced high-pressure shock tube. The reaction models for heptane, iso-octane, and toluene ignitions were updated by using the rate coefficients determined experimentally and theoretically for the key reactions. These model calculations could reproduce the observed. in the wide pressure range. However, the ignition delay times for two-component mixtures of these hydrocarbon fuels could not be reproduced by the reaction models constructed by combining each mechanism. These disagreements are caused by the cross reactions, which are the reactions between the radical intermediates, so elucidation of the cross reactions is a challenge for the future.
