In the exhaust emission control system of an internal combustion engine, NOx selective reduction catalyst 15, the engine is located in an exhaust passage, an aqueous solution of urea stored in the urea aqueous solution tank 20, for selectively reducing the NOx NOx selective reduction catalyst (15 ) it is supplied to the. The concentration of the urea aqueous solution in the NOx sensor 41 is provided in the NOx selective reduction catalyst 15 downstream of the engine exhaust passage to detect the NOx conversion efficiency of the NOx selective reduction catalyst 15, the urea aqueous solution tank 20 is detected It is estimated from the NOx. Exhaust emission control system and method make it possible to detect the concentration of the urea aqueous solution with a reduced cost.
