Vaporization Characteristics and Liquid-Phase Penetration for Multi-Component Fuels 2004-01-0529

The maximum liquid-phase penetration and vaporization behavior was investigated by using simultaneous measurement for mie-scattered light images and shadowgraph ones. The objective of this study was to analyze effect of variant parameters (injection pressure, ambient gas condition and fuel temperature) and fuel properties on vaporization behavior, and to investigate liquid phase penetration for the single- and multi-component fuels. The experiments were conducted in a constant-volume vessel with optical access. Fuel was injected into the vessel with electronically controlled common rail injector. It was observed that: • Liquid phase length is influenced by fuel properties, boiling point temperature, density and viscosity, etc. • The injection pressure has a little effect on the liquid phase length. • High-boiling point fuel within the multi-component fuel controls liquid phase length. • The difference in vaporization rate among the multi-component fuels with a different mass fraction gradually grow smaller with rising fuel temperature and ambient gas one. • Batch distillation characteristics of multi-component fuel are more apparent at low ambient temperature.
