| Outline of Final Research Achievements |
As a result of the ignition and combustion experiment of premixed mixture by the non-equilibrium plasma, the pressure rise became fast. Just after the spark discharge in the igniter, the flame was maintained in the plug hole, and then a large amount of flame flowed out from the plug hole. As a result, the spread of the flame has become faster. Also a result of emission analysis of a non-equilibrium plasma discharge, was similar to the emission spectrum of normal spark ignition. Therefore, there exists no unique combustion acceleration effect from the non-equilibrium plasma discharge.
In addition, the pulsed flame jet (PFJ) was used for controlling the combustion of homogeneous charge compression ignition (HCCI) combustion. It was shown that PFJ was effective to control in the ignition and the expansion of the operation area.
