Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/156210
Kind Code:
A1
Abstract:
An internal combustion engine according to the present invention is provided with a supercharger, an air bypass valve, a wastegate valve, and an EGR device. In addition, the internal combustion engine comprises an ISC passage that connects the upstream side and the downstream side of a throttle valve in an intake passage and an ISC valve that regulates the amount of air that flows through the ISC passage. A control device according to the present invention performs valve opening control in which the opening degree of the ISC valve is set to be larger than a standard opening degree when the required torque that is required from the internal combustion engine is smaller than an estimated torque that the internal combustion engine is capable of generating, and fully opens the air bypass valve and wastegate valve during a fixed period after the valve opening control when an EGR valve of the low-pressure EGR device is open during the execution of the valve opening control.
