The present invention even when the humidity of the intake air is high, while suppressing the deposits in the combustion chamber and the exhaust port, to provide an exhaust purification device which can purify NO
X-contained in exhaust.
An exhaust purification device of an internal combustion engine is provided in the exhaust passage 26, and the
the NO
X storing catalyst 30 for reducing the NO
X-by reducing agent is supplied. Exhaust purification device, when the humidity of the intake air detected by the humidity sensor 20 is a predetermined value or more, than when it is less than the predetermined value, supplying reducing agent to the NO
X storing catalyst 30 in the fuel injection valve 4a~4d as well as reduce the amount of fuel to be injected in order to, the fuel addition valve 5 provided in the exhaust passage 26 to increase the amount of fuel to be injected.
