The paper deals with the computer simulation of the Diesel fuel spray combustion under the similar conditions as in Diesel engines. A mathematical model of the spray propulsion and combustion is treated which allows the observation of the phenomena in the spray during its movement through air. Fuel droplets of the spray are vaporized due to the transfer of heat from hot air. In a certain moment when required conditions are met selfignition of mixture occurs. In order to determine the points where selfignitions occurs first, we have introduced the term “ignition probability” referring to the local air ratio and fuel dispersion in the spray.
