置。[Claims for Utility Model Registration] Based on input signals from various sensors installed in an internal combustion engine having a supercharger, an abnormality in the supercharger is determined and information regarding the abnormal part of the engine is output. This is a diagnostic device for a fuel feeder, and an input signal stability determination device that determines whether input signals from a rack sensor that detects displacement of a fuel rack, an engine output sensor, an engine rotation speed sensor, and a supercharger rotation speed sensor are stable. a standard rotation speed calculation means for calculating a standard rotation speed of the supercharger based on stable input signals from the rack sensor, the engine output sensor, and the engine rotation speed sensor; A rotation speed deviation calculation means for calculating a deviation by subtracting the standard rotation speed from the measured rotation speed represented by the input signal, and determining whether the deviation calculated by the rotation speed deviation calculation means is below a predetermined tolerance value. A supercharger characterized in that a rotation speed deviation determination means is provided, and information regarding an abnormal part of the engine is obtained based on the determination results of the input signal stability determination means and the rotation speed deviation determination means. Diagnostic equipment.
