The influence of fuel preheating on the evaporation curve of the
droplets should also be considered in this discussion. Preheating
adds a significant amount of energy to the fuel with respect to
the total energy needed for evaporation. As a result, the volatility
of the droplets is higher when they are injected into the combustion
chamber. Compared to the evaporation time, however, the
heat-up time of a droplet is relatively short and the wet bulb temperature
is reached quickly [43]. The total evaporation time of the
fuel droplets is therefore expected to be hardly affected by the preheating
temperature
