Abstract

In internal combustion engines, lean-burn is particularly attractive for minimizing pollutant emissions, in particular NOx, with a concomitant improvement in fuel economy. A Pulsed Flame Jet (PFJ) has a great potential to enhance ignition reliability and burning rate in lean fuel-air mixtures. In this study, two-dimensional images of OH radical in the jet of PFJ were obtained using a Planar Laser-Induced Fluorescence (PLIF) technique. The effects of equivalence ratio of the mixture in the cavity, cavity volume, and orifice diameter on the variation of OH fluorescence area in the jet and their intensity were revealed quantitatively.
