ABSTRACT:
Electronically controlled fuel injectors are capable of complex injection control methods, such as split injection. A calibration code assigned to each injector is used by a logic controller to determine calibrated energizing times based on raw energizing times determined by the engine control unit. Each injector may be individually calibrated to compensate for injector variability, and facilitate balanced power output from each cylinder.
