Lean-burn spark ignition engines have the attribute of minimizing the emission of NOx and, concomitantly, maximizing fuel economy. For combustion in lean fuel-air mixtures, achievement of adequate reliability of ignition and sufficiently high burning rate requires special devices. The most effective among them is the injection of active radicals by means of the Pulsed Flame Jet (PFJ) ignition system. Presented here is an experimental proof of the action of OH radical produced by such an ignition system in a swirl flow with varying the spark discharge mode in the cavity of the PFJ igniter. The measuring apparatus used for this purpose was based on the Planar Laser-Induced Fluorescence (PLIF) method, and the effects of the spark discharge mode in the cavity of the PFJ igniter on the variation of OH fluerencence area in the jet and its intensity were revealed quantitatively.
