Abstract:
In order to supply a reducing agent to two NOx catalysts arranged in series in an appropriate manner, normal control in which an additive agent of an amount according to an amount of NOx flowing into an upstream side NOx catalyst is added from an upstream side of the upstream side NOx catalyst, and decrease control in which when an amount of ammonia adsorbed to a downstream side NOx catalyst exceeds a predetermined upper limit amount in cases where the two NOx catalysts have been activated, an amount of additive agent to be added from a first addition valve is made smaller than the amount of additive agent to be added at the time of the normal control, are carried out.

Claim (Index 4):
The exhaust gas purification apparatus for an internal combustion engine as set forth in  claim 2 , wherein\n in said decrease control, said controller is further configured to set the amount of the additive agent to be added from said first addition valve to an amount in which a sum of the NOx reduction rates in said first NOx catalyst and said second NOx catalyst becomes equal to or larger than a reduction rate threshold value.
