Abstract
An exhaust gas purification system includes a dosing control unit that controls a supply module to supply urea water between a dosing valve and a urea tank in order to remove urea water accumulated in the dosing valve, when receiving a diesel particulate filter regeneration authorization request from an engine control unit, and then transmits the authorization to the engine control unit, when determining that an NHamount of a selective reduction catalyst is less than or equal to a prescribed value.
