Abstract

A combustion control apparatus for an internal combustion engine that switches combustion modes at the proper timing. At the time of switching from a stratified-charge combustion mode to a homogeneous-charge combustion mode, the angle of an EGR valve is changed to the angle needed for the homogeneous-charge combustion mode first. When a predetermined delay time elapses after a request for switching the combustion mode has been made, substantial mode switching is carried out. The delay time is set based on engine speed and engine load.
