ABSTRACT:
A control apparatus for an internal combustion engine that includes right and left banks, first and second catalysts provided in the right and left exhaust pipes, respectively, and a downstream catalyst provided in a common exhaust pipe downstream of the upstream catalysts is adapted to alternately switch execution of catalyst degradation minimization and execution of fuel cut between the two banks if at least one of the temperature of the first catalyst and temperature of the second catalyst is higher than a predetermined value during deceleration of the internal combustion engine.
