Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/103548
Kind Code:
A1
Abstract:
The invention relates to a control device for an internal combustion engine that includes a turbocharger, and an actuator that changes a turbocharging pressure by regulating exhaust energy for use in drive of the turbocharger. When a target torque is increased during execution of a lean burn operation, the control device switches an operation mode of the internal combustion engine from the lean burn operation to a stoichiometric operation. When the operation mode switching is performed in a turbocharging state, the control device determines whether a target torque is within a range of a torque realizable under the lean air-fuel ratio. When the target torque is within the range, the control device operates the actuator so as to keep the turbocharging pressure at a magnitude equal to or larger than a magnitude at a time point at which the operation mode is switched.
