CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

The present invention provides a control device applied to an internal combustion engine having a supercharger and a control value. The supercharger contains an opening-area control member that changes an amount of energy of the exhaust gas entered into the supercharger by controlling an opening-area of an approach zone. The control valve changes an amount of energy of the exhaust gas entered into the supercharger by controlling a valve-opening degree. The control device has a control means that gives an instruction to the opening-area control member so as to change the opening-area of the approach zone based on a target difference in the valve-opening degree and a parameter relating to a response-time length, when an instruction is given to the control valve at an predetermined instruction time point so as to change the valve-opening degree by the target difference.
