    摘要: [Problem] To provide a reducing agent supply apparatus that can quickly melt urea aqueous solution solidified in a reducing agent injection valve to allow early start of the injection control of urea aqueous solution, a method for controlling the reducing agent supply apparatus, and an exhaust gas purification apparatus.[Means for Resolution] reducing agent supply apparatus, including: a storage tank for storing liquid reducing agent; a pump for pumping the reducing agent; a reducing agent injection valve for injecting the reducing agent pumped by the pump in an exhaust pipe of an internal combustion engine; and a reducing agent passage connecting the pump to the reducing agent injection valve, wherein, when the internal combustion engine stops, a purge process of collecting the reducing agent in the reducing agent passage into the storage tank is performed, and wherein, on part of the reducing agent passage, a siphon function portion is provided for, even when, at the start of the internal combustion engine, the reducing agent injection valve is in injection failure due to solidification of the reducing agent in the reducing agent injection valve, causing some of the reducing agent to reach the reducing agent injection valve after the start of the pump to cause the solidified reducing agent to melt.
