ABSTRACT:
The present invention judges whether an internal combustion engine is operated by a special operation method in which a fuel cut is performed more frequently than predefined depending on the operation of an accelerator pedal. The present invention provides a shorter purge resumption period subsequently to recovery from a fuel cut when it is judged that the internal combustion engine is operated by the special operation method than when it is judged that the internal combustion engine is not operated by the special operation method. The purge resumption period is a period during which a purge gas flow rate is lower than during a steady operation.
