Document Type and Number:
WIPO Patent Application WO/2022/209707
Kind Code:
A1
Abstract:
An ECU (60) comprises: an index calculation unit for calculating a first index representing a margin of knocking resistance, and a second index representing required ignition energy required for normal ignition as indexes relating to fuel properties; a first control unit for setting a target in-cylinder temperature on the basis of the first index, and controlling the in-cylinder temperature on the basis of the target in-cylinder temperature, as in-cylinder temperature control for controlling the in-cylinder temperature immediately before combustion; and a second control unit for setting a target EGR rate on the basis of the second index, and controlling the EGR rate on the basis of the target EGR rate, as EGR control for controlling the EGR rate by an EGR device.
