A cooling device for a reducing agent injection module, includes a reducing agent injection module installed in an exhaust pipe to inject a reducing agent into the exhaust pipe and having a module cooling channel therein through which a coolant flows to cool the reducing agent injection module, a coolant pump configured to supply the coolant to the module cooling channel, a coolant circulation line including a coolant supply line and a coolant recovery line to connect the coolant pump and the module cooling channel, and a coolant recovery portion installed in the coolant recovery line to store the coolant flowing through the reducing agent injection module and positioned higher than the reducing agent injection module along a gravitational direction.

Cooling device for reductant spray module, and selective engine cooling sytem having same

A selective catalytic reduction system includes a reducing agent injection module installed in an exhaust pipe through which an exhaust gas is discharged from an engine and configured to inject a reducing agent into the exhaust pipe, a temperature calculator configured to calculate a temperature of the reducing agent injection module using temperature-related information of the reducing agent injection module, and a temperature controller configured to control to increase a reducing agent injection amount of the reducing agent injection module when the calculated temperature.
