摘要： When a catalytic converter is to be warmed up, a required efficiency (ηtag) for internal combustion engine control is set to a value within a range of less than 1, 1 representing a value when the conversion catalyst is not to be warmed up. The value is increased with an increase in delay of an open-close timing (VT) of an intake valve (steps S130 to S160). A delayed amount of a target ignition timing (IT*) is decreased with an increase in required efficiency (ηtag closer to the value 1; steps S170 and S180).

摘要： Disclosed is a control device applied to an internal combustion engine provided with a fuel vapor treatment system for treating collected fuel vapor by purging the collected fuel vapor into intake air downstream from an air flowmeter (6) and an exhaust gas recirculation system for recirculating part of exhaust gas in the intake air using intake negative pressure. An electronic control unit (22) performs an advance correction corresponding to the exhaust gas recirculation quantity regarding the MBT ignition timing and the knock limit ignition timing, and corrects the volumetric efficiency of the internal combustion engine, which is used for the calculation of the advance correction quantity used for the advance correction, according to the purge air quantity. Consequently, regardless of the decrease of the exhaust gas recirculation quantity caused by the implementation of a large quantity of purge, the appropriate advance corrections of the MBT ignition timing and the knock limit ignition timing become possible.
