Abstract (en)
[origin: EP0718492A1] An electromagnetic fuel injector (10) for the discharge of discrete spray streams (16,18) of fuel to separate intake valves of an internal combustion engine is disclosed. The injector has a valve member (50) moveable between open and closed positions with respect to a valve seat (52) and includes a fuel director plate (20) having fuel injector orifices (19) extending through said director plate which are aligned so that discrete streams (16,18) of fuel depart from the injector plate when said valve is open. The fuel injector also includes an air director plate (90) for discharging pressurized, atomization air. The director plate has a central opening (120) for the passage of the discrete fuel streams and a first group of associated atomizing air orifices (116), at predetermined locations, and oriented to direct atomizing air towards the fuel streams to impinge thereon and produce a finely atomized fuel spray. A second group of associated atomizing air orifices (118) directs atomizing air between the fuel streams to maintain separation thereof. <IMAGE> <IMAGE>
