Title:
内燃機関の制御装置
Document Type and Number:
Japanese Patent JP5741678
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To stabilize combustion while suppressing torque fluctuation by ISC valve control.SOLUTION: An internal combustion engine includes a supercharger, an air bypass valve, a waste gate valve, and an EGR device. The internal combustion engine further includes: an ISC passage for interconnecting an upstream side and a downstream side of a throttle valve in an intake passage; and an ISC valve for controlling the amount of air flowing in the ISC passage. When torque required for the internal combustion engine is smaller than estimation torque that may occur in the internal combustion engine, a control device performs valve opening control to make an opening of the ISC valve larger than a reference opening, and when an EGR valve of the low pressure EGR device is opened during execution of the valve opening control, the control device closes the air bypass valve and the waste gate valve for a certain period after the valve opening control is completed.
