Abstract

An abnormality determination device for an internal combustion engine (1) is provided. The internal combustion engine (1) includes a NOx purification catalyst (41) and a reducing agent supply mechanism (200). The abnormality determination device includes a NOx sensor (150) and an electronic control unit (80). The electronic control unit (80) is configured to determine, as an abnormality determination processing, that a concentration of the urea water is an abnormal concentration in a case where a difference between a first NOx amount and a second NOx amount detected by the NOx sensor (150) is equal to or lower than a predetermined value and in a case where a difference between a first exhaust gas temperature and a second exhaust gas temperature exceeds a predetermined temperature.
