In order to study the effects of liquid fuel volatility on the structures and characteristics of propagating spray flames, the temperature fluctuations when a spray flame passes a fine thermocouple have been measured for three liquid fuels with different volatility. In the same time with the temperature measurement, aspects of the propagating flame were filmed using a high-speed video camera. For low volatility fuels (decane and hexadecane), the flame propagating velocity and flame-zone thickness were founded to change slightly, respectively, although the fuel supply quantity changed greatly. For a high volatility fuel (hexan). however, the flame propagating velocity took a remarkable peak value and then decreased as the fuel supply quantity increased. The flame-zone thickness became small as the fuel volatility increased.
