For example, extended ignition helps prolong the time that the engine run. On the other hand, fast ignition offers higher power gain. Another important aspect is the pollution caused by an undesirable chemical reaction determined by the ignition profile. Based on a procedure developed in an earlier article, we examined the impact of different theoretical PSD distributions on the thermal ignition profile. We have compared different particle size distributions (PSD) of polydispersed fuel spray with normal distribution with various means, each with the same amount of fuel volume. Our results reveal a significant dependency of thermal ignition on the PSD distribution. Systems that consist of only low radii droplets do not reach ignition, while systems with only high radii take a long time to establish ignition. Moreover, the change in droplet means radius shows an unexpected result of a double hump in the maximums temperature of the combustion process.
