摘要： An internal combustion engine wherein when an aqueous urea solution should be fed from an aqueous urea solution feed valve (8), a feed pump (9) is operated forward and aqueous urea solution in an aqueous urea solution tank (4) is fed through an aqueous urea solution feed passage (10) into the aqueous urea solution feed valve (8). When ceasing the feed of aqueous urea solution from the aqueous urea solution feed valve (8), the feed pump (9) is operated in reverse whereby the ammonia gas generated in the aqueous urea solution tank (4) is drawn through a ammonia gas feed pipe (11) into the aqueous urea solution feed passage (10). Next, when the feed pump (9) is operated forward, the ammonia gas drawn into the aqueous urea solution feed path (10) is ejected from the aqueous urea solution feed valve (8).

摘要： In an internal combustion engine, an NOx selective reduction catalyst (15) is arranged in the engine exhaust passage, and the amount of deposition of the HC deposited at the NOx selective reduction catalyst (15) is estimated. When the estimated HC deposition amount exceeds a predetermined allowable deposition amount, the NOx selective reduction catalyst (15) is raised in temperature to make the deposited HC desorb from the NOx selective reduction catalyst (15), and thereby the NOx selective reduction catalyst (15) from HC poisoning is restored.

摘要： In an internal combustion engine, an NOx selective reduction catalyst (15) is arranged in the engine exhaust passage and a urea aqueous solution stored in a urea aqueous solution tank (20) is fed to the NOx selective reduction catalyst (15) where the NOx is selectively reduced. Opening and closing of the urea aqueous solution refill port (40) of the urea aqueous solution tank (20) are detected and it is judged if the urea aqueous solution is refilled in the urea aqueous solution tank (20). When it is judged that the NOx purification rate has fallen to an allowable level or less at the time of engine operation right after the urea aqueous solution is refilled in the urea aqueous solution tank (20), it is judged that the refilled urea aqueous solution is abnormal.
