A method for calculation of the fuel jet evolution in the open combustion chambers of diesels is created. The method can take into account the impact of the rising edge of the hydro-pulse of injection pressure and the feeding of the jet with the atomized fuel and makes it possible to improve the precision of calculation of the fuel jet range. The experimental studies of the influence of the injection pressure, air charge density and diameter of the atomizing openings as well as of the thermal and gas-dynamical effect of air charge upon the fuel jet evolution are performed.
