Control apparatus for internal combustion engine |
摘要 |
An object of the present invention is that after return from fuel cut, an oxygen storage amount in a catalyst in an exhaust path and an oxygen storage amount in a catalyst in an exhaust gas recirculating path are promptly adjusted to be in appropriate states, respectively. A control apparatus for an internal combustion engine of the present invention controls the internal combustion engine including a recirculating gas generating cylinder and a recirculating gas nongenerating cylinder. The control apparatus includes: an exhaust gas recirculating path for connecting the exhaust path through which exhaust gas only in the recirculating gas generating cylinder is delivered and an intake system; a recirculating catalyst provided on the exhaust gas recirculating path; and rich control means that performs rich control for controlling an air-fuel ratio to be temporarily richer than a theoretical air-fuel ratio when fuel injection is restarted after return from the fuel cut. The rich control means includes air-fuel ratio control means that controls an air-fuel ratio in the recirculating gas generating cylinder to be richer than an air-fuel ratio in the recirculating gas nongenerating cylinder when the rich control and an exhaust gas recirculation by the exhaust gas recirculating path are simultaneously performed. |
