ABSTRACT:
A fuel injection device for an internal combustion engine comprises an electrically controlled injector having a body removably connected in a passage opening into an engine induction passage. The body has a nose of reduced diameter. A cap is fitted on the nose of the injector and formed with a fuel jet outlet opening. The cap and nose of the injector define an air chamber. Lateral openings of the cap communicate the air chamber with a space formed between the cap and the wall of the passage, connected to an air source. A spacer plate is retained between the cap and the nose and formed with a central calibrated hole surrounding an outlet of the injector for constituting a calibrated fuel and air jet outlet passage. The spacer plate is retained between the nose and the cap in a predetermined position.
