Abstract
A urea water agitation control device has an agitation control portion and a temperature sensor which detects a temperature of a urea water. The agitation control portion operates an agitation portion in a specified period which includes a part of a period in which the urea water temperature detected by the temperature sensor is kept at a eutectic point and the urea water radiates a latent heat of solidification.
