FIELD: engines and pumps.
SUBSTANCE: proposed fuel injector comprises body with flange at its rear for attachment of fuel valve to engine cylinder cover, elongated atomiser with axial bore and closed front part, valve needle elastically displacing to interact with valve seat and to control fuel flow into said atomiser. Outlets are distributed over atomiser length so that to make their axes align with atomiser central channel axis. Hollow cover rod can displace together with valve needle and axially shift between up position and down position in atomiser central bore for opening and closing of said outlets. Cover rod comprises orifices corresponding to outlets to communicate all outlets and rod inner cavity in lifted position as well as shutting off of all outlets and rod inner cavity in closed position. Cover rod may not rotate relative to atomiser and fuel valve body.
EFFECT: optimum performances.
