| titleOfInvention | Exhaust gas purification device for internal combustion engine |
| abstract | An exhaust purification device for an internal combustion engine is provided that can accurately determine whether or not deposits adhering to a mixing member need to be melted and removed. An exhaust emission control device for an internal combustion engine includes a selective reduction catalyst for selectively reducing nitrogen oxides contained in exhaust gas discharged from the internal combustion engine, and urea reduction in an exhaust passage upstream of the selective reduction catalyst. Supplied from a reducing agent supply means for supplying the agent, a stirring mixer for promoting mixing of the exhaust gas flowing in the exhaust passage and the urea reducing agent supplied by the reducing agent supply means, and the reducing agent supply means A deposit amount estimating means for estimating the deposit amount of the deposit generated by the urea reducing agent being deposited on the stirring mixer, the deposit amount estimating means, from the total amount of urea reducing agent supplied from the reducing agent supply means, The consumption amount of the urea reducing agent used for the reduction of nitrogen oxides and the adsorption amount of the urea reducing agent adsorbed on the selective reduction catalyst are subtracted to obtain a deposit accumulation amount.
