Outline of Final Research Achievements |
It is extensively known that higher hydrocarbon fuels used for automobile and jet engines exhibit cool and hot flames, so-called, multi-stage oxidations. Clarification of multi-stage oxidations are essential for solving knocking and combustion instabilities which limit further improvements of engine efficiencies. In this study, reaction zone of the low-temperature oxidation was successfully separated from multiple weak flames of n-heptane using an original method, "flame chromatography," i.e., a micro flow reactor with a controlled temperature profile (MFR). A separated steady cool flame from multiple weak flames of n-heptane was stabilized for the first time and chemical structure of single cool flame in MFR was clarified by species measurements. Essential information on the capabilities of the current reaction kinetics in predicting low-temperature oxidations and issues of their improvements.
