Abstract (en)

[origin: WO9720136A1] A method for retaining and recalling technical data associated with a solenoid-operated fuel injector (10) improves engine emissions. Each fuel injector is tested to generate technical data specifications relating to the fuel injector. The technical data specifications are then transferred (46) to the fuel injector (10), such as by using a laser marking system to mark the injector with a bar code (44) containing the technical data specifications. The technical data specifications can then be read from the fuel injector such as by using a scanner. The recalled technical data specifications are then provided to a vehicle computer. The vehicle computer adjusts for variations between fuel injectors to collapse variability of injectors to a single, centered injector flow.
