A nozzle for injection of liquid fuel directly into cylinder of combustion engine and film atomization of fuel has a body, normally closed sprinkler of valve type that comprises injecting seat end outer surface of which is normal to its axis of symmetry, and injecting needle with rack shutoff cone, spring that provides tightness of sprinkling. The injecting needle in the base of back locking cone has coaxial cylindrical nozzle with diameter smaller than diameter of the base of back locking cone, and transition from the base of back locking cone to cylindrical nozzle is implemented in inner radius, at that length of the nozzle is larger than diameter of the base of back locking cone. |
