Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2020/179500
Kind Code:
A1
Abstract:
This control device (70) has a supercharge switching means (71A) for switching the number of superchargers used for supercharge control. A total loss torque estimation system (71B) is provided for estimating the total loss torque caused by falling in supercharge in a switching transition period directly after switching the number of superchargers. A first required torque calculating means (71C) is provided for calculating a first required torque according to the estimated total loss torque. An injection start time correction amount calculating means (71D) is provided for calculating an injection start time correction amount on the basis of the calculated first required torque. An injection start time changing means (71E) is provided for causing the injection start time of a fuel to be earlier than a normal injection timing on the basis of the calculated injection start time correction amount.
