The physical properties of the fuel, such as density, viscosity, surface tension, and bulk modulus of elasticity, affect many aspects of the diesel injection process. The effects of these fuel properties on the fuel pressure in the high-pressure line, rate of injection, leakage, spray penetration, and droplet size distribution were determined experimentally. The mechanism of spray development was investigated by injecting the fuel into a high-pressure chamber. A pulsed Malvern drop-size analyzer, based on Fraunhofer diffraction, was utilized to determine droplet size ranges for various fuels.
