Abstract:
1. A method for controlling an injector in a fuel cell system, said method comprising: setting an injector pulse width for at least one predetermined duty cycle; determining an injector close time for the at least one predetermined duty cycle based on the injector pulse width; changing the injector pulse width for the at least one predetermined duty cycle; determining an injector close time for the at least one predetermined duty cycle based on the changed injector pulse width; repeating the step of changing the injector pulse width for the at least one predetermined duty cycle such that a variety of injector pulse widths are used for the at least one predetermined duty cycle; repeating the step of determining injector close time for the at least one predetermined duty cycle each time the injector pulse width is varied such that injector close time is determined for each of the variety of injector pulse widths for the at least one predetermined duty cycle; determining an error for the at least one predetermined duty cycle for each of the injector pulse widths used; and using the injector pulse width with the lowest error for the at least one predetermined duty cycle.
