Abstract

This paper presents a direct photographic imaging and image processing system for the analysis and characterization of diesel sprays. A high-resolution CCD camera with a flash light source is used to capture the spray images through an optically accessible, constant volume chamber. A set of macroscopic characteristic parameters of the sprays including tip penetration, near and far field angles, spray tip velocity and average fuel area density are derived from the images. Experimental work was undertaken on a common rail fuel injection rig. The relationships between the spray characteristics and corresponding injection conditions are presented and discussed
