| description | PROBLEM TO BE SOLVED: To provide an exhaust purification system capable of preventing clogging in a reducing agent injection valve caused by the solidification of an aqueous urea solution before it happens, and preventing the decline of exhaust purification efficiency in an internal combustion engine.SOLUTION: The exhaust purification system with a DPF, a reducing agent injection valve, and an SCR catalyst in order from the exhaust upstream side includes: a condition establishment determination unit for determining whether there is a risk of solidification of an aqueous urea solution after an internal combustion engine is stopped, when the internal combustion engine is stopped or in assuming that the internal combustion engine is stopped during the operation of the internal combustion engine; and a driver notification unit for giving notice to a driver on the basis of the determination result of the condition establishment determination unit. |
