A fuel injection system comprising a fuel injection nozzle having a fuel injection orifice, and a vibrator for producing atomization of the fuel injected by the nozzle, the nozzle being equipped at the inlet side of the orifice with a fuel retaining valve which is arranged to normally close the orifice and thus prevent the injection of fuel by the nozzle and which is adapted to move away from the orifice when the vibrator is activated and thus allow the injection of fuel by the nozzle, the nozzle being provided with a mechanical stop device so positioned at a distance from the orifice and in the path of the valve as to limit the maximum possible travel of the valve away from the orifice to that giving a maximum predetermined amount of fuel injection by the system. |
