摘要： PROBLEM TO BE SOLVED: To accurately diagnose abnormalities of a reducing agent feeder. SOLUTION: A diagnostic device is provided with a fuel supply system, a temperature detection means, and a diagnostic means. The fuel supply system is provided with a fuel-adding valve arranged in an exhaust system of an internal combustion engine, and the temperature detection means detects the temperature in proximity to the injection hole of the fuel-adding valve. The diagnostic means diagnoses the abnormalities of the fuel supply system based on the temperature detected by the temperature detection means. Because of this setup, since the amount of reduction in temperature in proximity to the injection hole of the fuel-adding valve, which is uniquely in correlation with a fuel supply amount, is detected as a parameter, the diagnostic precision in the diagnosis of the abnormalities of the fuel supply system can be improved.
