CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

A control apparatus for an internal combustion engine (10) in the present invention includes a DPF (28) installed in an exhaust passage (16) and a DOC (26) installed in the exhaust passage (16) on the upstream side of the DPF (28). The control apparatus changes an engine control parameter so as to facilitate NO 2 -based regeneration when it is determined that an operating state in which the NO 2 -based regeneration speed is higher than a predetermined threshold value is established during operation of the internal combustion engine (10).
