ABSTRACT:
A method for retaining and recalling technical data associated with a solenoid-operated fuel injector 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 to a memory means, such as an EEPROM memory chip, which is attached to the fuel injector. The injector then carries its unique technical data specifications. The technical data specifications can then be read from the fuel injector and the recalled technical data specifications are 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.
