Abstract
A fuel injection installation method includes detecting an actuation timing of a first valve of a fuel injector, detecting an actuation timing of a second valve of the fuel injector, detecting a return timing of the first valve of the fuel injector, and detecting a return timing of the second valve of the fuel injector. The method includes, for one or more fuel injection events, modifying at least one of: a maximum amplitude of solenoid current, an average amplitude of solenoid current, a start time of solenoid current, an end time of solenoid current, or a total time of solenoid current. The modification is based on the actuation timing of the first valve, the actuation timing of the second valve, the return timing of the first valve, and the return timing of the second valve, and may be performed for installation of the fuel injector.
