摘要：The invention makes the identification of defects possible in a fuel injectionsystem comprising a fuel accumulator (12), a continuously operating high-pressure pump(10) and a fuel pressure control valve (14). By evaluating the high-frequency portion ofthe fuel pressure course in the fuel accumulator (12), it can be indicated with a highprobability which of the components are defective, whereby this is assisted, in particular,by additional evaluations performed during a diagnostic method.
