Disclosed is a combustion controller which can provide control to a homogeneous charge compression ignition engine for allowing a premixed combustion region and a main combustion region (diffusion combustion region) to occur in a combustion chamber. The controller controls the premixed combustion region in terms of the required amount of heat and adjusts the fuel injection pattern for the premixed combustion region, i.e., the ratio of the amount of injected fuel between a first injection and a second injection in the premixed combustion region, thereby continuously changing the degree of premixing (the amount of premixed combustion) in the premixed combustion region. This allows for implementing an appropriate combustion pattern depending on the running status of the engine, thus ensuring improved exhaust gas emission and sufficient engine torque. |
