| Outline of Final Research Achievements |
In this study, we focused on a microflow reactor (MFR) as a method to capture the ignition phenomenon occurring in a reciprocating engine and examined a method to easily estimate the ignition delay time. Specifically, we proposed an estimation method that combines ignition position information and ignition delay time using "Livengood - Wu integral." We conducted experiments using a mixed fuel of normal heptane and iso-octane, which is a standard fuel for evaluating knocking in engine. As a result of these experiments, it is possible to obtain an ignition photograph even with very lean premixture in MFR, that is difficult to obtain in other numerical calculations and experiments. This leads that it is possible to estimate the ignition delay time under the super lean burn condition.
