A Study on Entrainment Characteristics in Diesel Spray

- Effects of Fuel Injection Pressure on Spray Characteristics -

Abstract

The purpose of this report is to grasp the entrainment characteristics in diesel sprays. Here, shadowgraph photography, scattered light photography and analysis of free spray in noncombustible field was carried out by using a constant volume vessel. As the result of measurement using shadowgraph photography and scattered light photography, it was found that spray volume is larger with the rise of fuel injection pressure, and spray volume of evaporation field is larger than that of non evaporation field.
