Title:
CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2012251464
Kind Code:
A
Abstract:

To provide a control apparatus for an internal combustion engine that can suppress a sudden change of an engine rotation speed caused by the change of an operating angle of an intake valve.

When the working angle of the intake valve is increased in accordance with a deficiency in a working fluid pressure of a VVT mechanism 9, an electronic control unit 1 corrects an opening degree of a throttle valve 7 so as to increase an intake air amount, and thereby suppressing the intake air amount from decreasing in accordance with the increase in the working angle with a valve timing of the intake valve retarded, and hence suppressing a fall in the engine rotational speed.
