Abstract
When, in a coexistence region where stratified combustion by a spray-guide method (SG combustion) and stratified combustion by a wall-guide method (WG combustion) are both practicable, a change from the SG combustion to the WG combustion is carried out, an ECU obtains point b giving a set of a fuel injection timing and an ignition timing capable of achieving the same target torque as a target torque in the SG combustion before the change, by the WG combustion, and changes the fuel injection timing and ignition timing stepwise from point a within an SG region to point b within a WG region, jumping across a misfire region, and then continuously to point c giving an optimal set of a fuel injection timing and an ignition timing corresponding to an MBT.
