Beschreibung
Zusammenfassung:	An abnormality determination device which is capable of shortening a time period required for performing abnormality determination of a plurality of devices, in a state in which the supply of evaporated fuel to an intake system is stopped, as a whole, thereby making it possible to increase the frequency of execution of the determination, and improve the throughput of an evaporated fuel processor for processing evaporated fuel. When first and second execution conditions are satisfied, respectively, first and second determination operations for determining the abnormalities of first and second devices, respectively, are performed in the state in which the supply of evaporated fuel is stopped. In a case where the first determination operation is completed, when the second execution condition has been satisfied, the second determination operation is started with the supply of evaporated fuel being held in the stopped state.
