The phenomenological characterization of the liquid phase penetration on the diesel spray through the combustion chamber is very important to prevent and to reduce the pollution emission on the heavy duty Diesel engines as well as new combustion chambers design, for this reason, this work has concentrated on the characterization of the macroscopic behavior of the liquid phase penetration of diesel spray. The main purpose of this research is to define the influence of the nozzle hole diameter, injection pressure, gas density and temperature in diesel spray penetration on evaporating conditions. The results show that the nozzle hole diameter and thermodynamics properties as the gas density and temperature have a significant effect on the liquid phase penetration, while the injection pressure has no significant effect on the maximum liquid phase penetration. Schematic diagrams and main components of the equipment, experimental layout for imaging tests, instantaneous spray images, example of the liquid phase penetration for different nozzle holes, injection pressures, different gas density and temperature are presented in the paper.
