Abstract
The ignition delay of a suspended fuel droplet in high ambient temperature was experimentally investigated. The fuel oils used in the experiment were 9 light cycle oils and 10 marine diesel fuels. The effect of ambient temperature on ignition delay was observed.
The result shows that there is a good relationship between ignition delay and evaporation time of the oils under higher ambient temperatures. The ignition delay increases with a decrease in the ambient temperature. For lower temperatures, the ignition delay increases step-wise. The ignition temperatures of the light cycle oils are higher than those of marine diesel fuels.
