More Information
Summary:A combustion control device is configured to control combustion in a combustion chamber of a compression ignition engine. An index detection unit is configured to detect multiple combustion state indices each indicating a combustion state in the combustion chamber. The multiple combustion state indices may include an ignition time point and an MFB50 time point, at which a combustion mass rate becomes 50% of total. A determination unit is configured to select a combustion state index from the multiple combustion state indices based on a determination condition such as an operation state of the engine. A control unit is configured to manipulate a parameter of the combustion state such as a fuel injection time point, at which a fuel injection valve injects fuel, so as to control the combustion state index at a target value.
