Document Type and Number:

WIPO Patent Application WO/2011/074302

Kind Code:

A1

Abstract:

Provided is a control device for an internal-combustion engine provided with a throttle valve installed in an intake path. A full intake air amount, which is the intake air amount corresponding to when the throttle valve is fully open, is calculated in accordance with engine revolution speed, and a theoretical intake air amount, which corresponds to when engine exhaust gas does not recirculate to a combustion chamber, is calculated in accordance with the full intake air amount and an intake pressure. An actual intake air amount of the engine is detected or estimated, and an exhaust gas recirculation rate is calculated using the theoretical intake air amount and the actual intake air amount. The engine is controlled using the calculated exhaust gas recirculation rate.
