抄録

A Pulsed Flame Jet (PFJ), formerly referred to as Pulsed Combustion Jet, has a great potential to enhance ignition and burning rate in lean fuel-air mixtures. In order to investigate the ignition mechanism of PFJ, radicals in the jets were measured. CH emission in the jet issuing into the combustion chamber, where the lean mixture was filled, was measured using a band-pass filter and a time-gated intensified CCD camera. OH radical in the jet issuing into the air was measured by PLIF (Planar Laser-Induced Fluorescence). In the tests, methane-air mixtures were used, and PLIF images were obtained in the plane perpendicular to the jet axis as well as in the plane of the jet axis. Then the variation of CH emission and OH fluorescence area and their intensity in the jet were revealed.
