Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2015059490
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of improving drivability, as a flow rate control valve can be stably driven by properly controlling driving means driving the flow rate control valve with a duty ratio according to an operating state of the internal combustion engine.SOLUTION: A control portion 14f restricts a duty ratio in energizing a first solenoid valve 19, a second solenoid valve 27 or a third solenoid valve 36, to a restricted duty ratio as a first duty ratio according to pressure difference between an upstream pressure and a downstream pressure of a turbine bypass valve 16, a waist gate valve 24 or a compressor bypass valve 29 set by a setting portion 14e, and keeps the turbine bypass valve 16, the waist gate valve 24 or the compressor bypass valve 29 at a full-close position.
