The experimental and theoretical analyses of fuel spray motion in a side-injection combustion system, which is used to control fuel spray motion with air swirl for dynamic fuel-air mixture formation, were shown in this paper. Experimental studies on the fuel spray motion with air swirl in a constant-volume test rig by means of high-speed photographic observation, and theoretical analyses of fuel spray motion in a combustion chamber using CFD multi-dimensional model, and of fuel velocity, spray motion in a combustion chamber using CFD multi-dimensional model, and of fuel velocity, spray trajectory, and excess air ratio in the fuel spray were carried out. From these studies, important results on the characteristics of fuel spray motion and dispersion in side-injection combustion systems were obtained and the usefulness of CFD multi-dimensional analysis for improving spray dispersion in the combustion chamber was shown.
