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 of an ECU controls an injector so as to start an initial fuel injection when a crank angle corresponds to an initial fuel injection start time, i.e., a time when a piston 4 arrives at such a position that the fuel injected from the injector reaches a lip 7 but falls short of reaching a bore wall face 3a of a cylinder 3, and terminate a final injection when the crank angle corresponds to a final fuel injection end time, i.e., a time when the piston 4 arrives at such a position that the fuel injected from the injector reaches the lip 7 but falls short of reaching a region below the lip 7 in a cavity 6a. |
