ABSTRACT:
A method for adjusting the on-time of each hydraulically-actuated fuel injector within a hydraulically-actuated fuel injection system is disclosed. At least two spray tests are performed on the fuel injector prior to its installation in a fuel injection system. The fuel injector is marked with a bar-code capable of representing these results. Immediately prior to installing the fuel injector into the fuel injection system, the bar-code on the fuel injector is scanned and the results of the spray tests are stored in a memory unit accessible to the electronic control module. These results are used to develop a unique electronic trim solution for the fuel injector. The performance of the fuel injector is then adjusted using the electronic trim solution to enable the performance of the fuel injector to approach that of a nominal injector.
