Patent ID: 7395148

Claim:
A fuel injection controller for a multiple-cylinder internal combustion engine of a compression ignition type, wherein a fuel injection valve of the internal combustion engine is operated on the basis of detection result of a detection means for detecting pressure in a combustion chamber of a part of the cylinders to control an ignition timing of each cylinder toward a target ignition timing, the fuel injection controller comprising: a part-of-cylinders control means for operating an injection timing of the part of the cylinders on the basis of the detection result by the detection means in the part of the cylinders to feedback control an ignition timing computed on the basis of the detection result toward the target ignition timing; and an other-cylinders control means for operating injection timings of other cylinders in such a way as to bring torques produced by combustion in the other cylinders in agreement with a torque produced by combustion in the part of the cylinders at a time of the feedback control performed by the part-of-cylinders control means, thereby controlling ignition timings of the other cylinders in such a way as to be in agreement with the ignition timing of the part of the cylinders.
