Visualization by the liquid injection technique, in which liquid fuel is injected into another liquid, was applied to an investigation of the spray developing processes in a small direct injection diesel engine. The injector was newly designed to obtain spray characteristics similar to a diesel spray in a high-pressure atmosphere. The spray injected into water by this injector has a penetration and break-up length similar to the diesel spray. The behavior of the spray in a swirling water flow was investigated. Sprays with different break-up lengths show different behavior in the same swirling water flow. The spray with a higher injection pressure shows a larger spray angle, a lower dispersion by the swirling flow before impingement with the combustion chamber wall, but wider distribution along the wall after the impingement.
