<p>PROBLEM TO BE SOLVED: To provide an exhaust purification device of an internal combustion engine capable of efficiently removing a product material produced due to an additive agent added to exhaust with a relatively simple configuration.SOLUTION: An exhaust purification device of an internal combustion engine introduces urea water 5 which is an additive agent, together with exhaust 1 exhausted from a diesel engine 60, into exhaust post-processing means (for example, a selective reduction catalyst 12). The exhaust purification device comprises: additive agent supply means (a urea water spray nozzle 21) which has a supply port 21a to supply the urea water 5 to the exhaust 1; and a condensate water supply device 30 which supplies condensate water 6 produced by condensing an intake air or the exhaust of the diesel engine 60 to a position close to the supply port 21a of the urea water spray nozzle 21.</p> |
