운전조건에 따른 D.I. 디젤기관의 분무·화염의 특성에 관한 연구 (배경산란광그림자사진법에 의한 해석)

A Study on the Characteristics of D. I. Diesel Spray·Flame in Operating Condition (Analysis by Diffused Background Illumination Method)

Optically accessible D. I. diesel engine with a rectangular combustion chamber was constructed to visualize the behaviors of sprays and flames in the combustion camber with the close conditions of pressure and temperature in an actual engine. The behaviors of sprays and flames in the combustion chamber as the operating conditions of this engine were photographed with high speed camera by Diffused Background Illumination Method. With photographs taken by this method, behavior of spray droplets injected into the combustion chamber, ignition points, and flame propagation were observed and analyzed at a time-and space-dependent fashion.
