Abstract

The high-speed photography system, constant volume bomb system, corresponding control system, and data acquisition system were used to collect the spray properties of air-assisted injection diesel and kerosene. The spray characteristics of diesel and kerosene at the same jet impulse width, injection impulse width, oil-gas interval impulse width, and injection pressure were compared and analyzed. The results show that under the same test conditions, the penetration length of diesel is larger than that of kerosene. As the injection impulse width and oil-gas interval change, the spray changes. The spray cone angle of kerosene is proportional to the injection impulse width and inversely proportional to the jet impulse width, which is the same as diesel. Moreover, the spray penetration length and spray cone angle of the two fuels are in direct ratio to the injection pressure. In addition, the cone angle of diesel spray is generally smaller than that of kerosene spray under the same pressure.
