Abstract
An ECU includes: an index calculation unit calculating, as indices relating to fuel properties, a first index that indicates a degree of anti-knocking margin and a second index that indicates required ignition energy required for normal ignition; a first control unit for setting a target in-cylinder temperature based on the first index and controlling an in-cylinder temperature based on the target in-cylinder temperature, as an in-cylinder temperature control for controlling the in-cylinder temperature immediately before combustion; and a second control unit for setting a target EGR rate based on the second index and controlling an EGR rate based on the target EGR rate as an EGR control performed by an EGR device for controlling the EGR rate.
