Analysis of Spatial Dispersion Characteristics of Improved Conical Sprays

The macro-characteristics of conical and improved conical sprays were analyzed using laser sheet and high speed camera. The injection pressure was 14.7, 24.5 or 34.3 MPa and the chamber pressure was 0.098, 0.98 or 1.96 MPa, where the amount of injected fuel was 28.5 mg per cycle, and the injection frequency was 8.3 Hz. As a result, at atmospheric pressure, both of the conical spray and improved conical spray have a conical pattern, but at high chamber pressure, the sprays become three dimensional. The penetration of the improved conical spray was about 25% stronger than that of the conical spray.
