Zusammenfassung:	For providing a combustion control device capable of decreasing unburned HC caused by a fuel attaching to a bore wall of a cylinder and unburned HC/CO produced by excessive diffusion of the fuel in premixed charge compression ignition combustion, an injector control unit controls an injector so as to start an initial fuel injection when a crank angle corresponds to an initial fuel injection start time when a piston arrives at such a position that the fuel injected from the injector reaches a lip but falls short of reaching a bore wall face of a cylinder, and terminate a final injection when the crank angle corresponds to a final fuel injection end time, when the piston arrives at such a position that the fuel injected from the injector reaches the lip but falls short of reaching a region below the lip in a cavity.
