摘要： A fourth cylinder is mounted with a cylinder pressure sensor. The injection timing of the fourth cylinder is operated so as to feedback control the ignition timing of the fourth cylinder, which is detected by the cylinder pressure sensor, to a target ignition timing. The ignition timings of the first cylinder to the third cylinder are indirectly controlled by operating the injection timings so as to make output torques produced by combustion in the first cylinder to the third cylinder correspond to an output torque produced by combustion in the fourth cylinder.

摘要： An abnormality determination device of a cylinder pressure sensor calculates a gain (sensing sensitivity coefficient) and an offset (bias) indicating an output characteristic of the cylinder pressure sensor. The device determines existence or nonexistence of an abnormality in the gain and the offset respectively. When the device determines that the abnormality exists, the device performs failsafe processing set in modes different from each other between the case of the abnormality in the gain and the case of the abnormality in the offset. As the failsafe processing in the case of the abnormality in the gain, the device performs processing for substantially prohibiting usage of a sensor value of the cylinder pressure sensor in control (fuel injection timing control) by using an alternative value (specified value) instead of the sensor value of the cylinder pressure sensor.
