Abstract
A control apparatus for a premixed compression ignition type internal combustion engine having, a fuel injection valve for supplying a fuel into a combustion chamber of the engine, an operational condition detecting unit for detecting the operational condition of the engine, and a fuel injection control unit for controlling the fuel injection valve on the basis of the results of the detection carried out by the operational condition detecting unit, the fuel injection control unit controlling the fuel injection valve so that the supplying of a fuel to the combustion chamber is finished at least before a piston reaches a compression top dead center. The control apparatus includes an air supply unit for supplying pressurized air to the combustion chamber, and an air quantity control unit for controlling the air supply unit. The air quantity control unit controls a supply rate of the pressurized air so that the combustion of a gaseous mixture by self-ignition is carried out by a compression effect of the piston of the engine when the piston is in the vicinity of a compression top dead center. This control apparatus secures an output corresponding to the time of a high-load operation of the engine as the reduction of NOx is effected.
