Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/199443
Kind Code:
A1
Abstract:
In the present invention, a target air quantity for achieving a required torque is calculated on the basis of the required torque using a virtual air-fuel ratio. The virtual air-fuel ratio is changed from a first air-fuel ratio to a second air-fuel ratio in response to the fulfillment of conditions for switching from operation using the first air-fuel ratio to operation using the second air-fuel ratio. After the virtual air-fuel ratio has been changed from the first air-fuel ratio to the second air-fuel ratio, a target air-fuel ratio is switched from the first air-fuel ratio to the second air-fuel ratio. Further, after the virtual air-fuel ratio has been changed from the first air-fuel ratio to the second air-fuel ratio, a target valve timing is switched from a first valve timing to a second valve timing.
