This paper shows that the visible observations of emulsified aspects by a Liquid-Liquid Injection Technique (L. I. T.) are applicable for the evaluation of engine performance. To contribute information for a square combustion chamber design and the engine performance, we studied the visible observations of emulsified spray aspects by using an optical-transmissivity of positive images. The L. I. T. makes use of momentary photo-images by 35 mm camera without the need for high-speed photography. It captures the forced swirling flow in positive film images which show the fuel-air mixing behavior as an intensity of scattering radiation. A relationship between the visible observation results of air-fuel mixing formation and engine performance was confirmed. This study clarified that the L. I. T. and the optical-transmissivity technique is practical and useful for the visible observation of mixture formation.
