Abstract
A control apparatus for an internal combustion engine determines, based on an output value of the downstream air-fuel ratio sensor, an air-fuel ratio of a gas flowing into the catalyst that is set to either a 'target rich ratio' or a 'target lean ratio', and determines a fuel injection amount. Disclosed is an evaporated fuel purge section for introducing an evaporated fuel generated in a fuel tank into an intake passage. The purge section starts the purge when the target air-fuel ratio is set to the target rich ratio at a purge execution condition satisfied time point at which a state has changed from a state in which the purge execution condition is unsatisfied to a state in which it is satisfied, and does not start the purge when the target air-fuel ratio is set to the target lean air-fuel ratio at the purge execution condition satisfied time point.
