Method and circuit arrangement for setting an injection strategy for an injector of a fuel cell system

Abstract

A method for setting an injection strategy for an injector (1) by way of PWM signals in order to inject fuel in a fuel cell system (2), has the steps of: setting an injection frequency to a predefinable first value within a predefinable value range with a predefinable pulse duration in the PWM signal using a setting unit (3), and adjusting the injection frequency to a predefinable second value, different from the first value, within the predefinable value range using an adjustment unit (4), wherein the pulse duration of the PWM signal is kept constant in order to change a duty cycle of the PWM signal of the injection strategy. A corresponding circuit arrangement (8), a fuel cell system (2) and a computer program (9) are also described herein.
