Abstract
A fuel injection device having three concentric streams of air for the atomization of fuel sprayed onto a sleeve by an injector facing into the sleeve. The inner and outer streams of air are imparted with swirl in opposite direction, while the central stream of air is free of swirl. The two inner streams of air atomize the fuel as a result of shear forces, while the outer stream of air forms a stable recirculation region in a combustion chamber into which the fuel injector device extends.
