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.
Claims16
A urea water agitation control device for an exhaust gas purifying device which supplies a urea water into an exhaust gas, the urea water agitation control device comprising:
- a controller including a computer processor for executing instructions such that the controller is at least configured to control a pump agitating the urea water stored in a storage tank;
- and
- a temperature sensor configured to detect a temperature of the urea water, wherein
- the controller is configured to operate the pump in a specified period which includes at least a part of a period in which a urea water temperature detected by the temperature sensor is kept at an eutectic point and the urea water temperature detected by the temperature sensor is higher than an ambient temperature so that the urea water radiates a latent heat of solidification.
A urea water agitation control device for an exhaust gas purifying device which supplies a urea water into an exhaust gas, the urea water agitation control device comprising:
- a controller including a computer processor for executing instructions for controlling a pump agitating the urea water stored in a storage tank, wherein the controller is configured to execute processing of:
- acquiring a urea water temperature of the urea water and an ambient temperature;
- and
- operating the pump in a specified period which includes at least a part of a period in which the urea water temperature is kept at an eutectic point and higher than the ambient temperature.
