Paper Abstract

Optically accessible D.I Diesel engine with a rectangular combustion chamber was constructed to visualize the behavior of sprays and flames in the combustion chamber with close conditions of pressure and temperature of actual engine. The behaviors of sprays and flames in the combustion chamber at compression stroke and expansion stroke in accordance with operating conditions were photographed with high speed camera by Back Illumination Scattering Method and Schlieren method. With photographs taken by these methods, behavior of evaporating sprays and spray droplets, ignition points, the flame propagation were observed and analyzed at a time- and space-dependent fashion with image processor.
