Beschreibung
Zusammenfassung:	A urea water supply system (10) which performs permission determination by a control device based on a first parameter includes a cooling water temperature sensor (24), and a control device (20) is configured to be able to store a result of the permission determination, and when a system control is restarted after the system control is stopped and a stop period (Δt) is elapsed, it performs a shortening setting to shorten a time required for the permission determination based on the determination result stored at a time when the system is stopped and a cooling water temperature (T5) immediately after restarting.
