N2 - The numerical investigations of liquid fuel ignition by local energy source - focused flow of light emission were conducted by using the developed physical and mathematical models. Features of high-speed processes of heat and mass transfer were established at ignition of three most typical types of liquid fuels (benzine, kerosene, diesel fuel) within the concerned system. The characteristic location of the zone of oxidation basic reaction in the immediate vicinity of the liquid fuel evaporation surface was determined. Minimal values of the energy density of focused radiant flux, when the main integral characteristic of studying process (ignition time delay td) is less than 1s, were calculated. Correlations which are limited for implementation of ignition condition were established. They are the correlations of the fraction of focused radiation source energy supplied to liquid fuel and expended for its evaporation.
