摘要： This invention determines whether or not an internal combustion engine is not performing combustion. If the determined result is that the internal combustion engine is not performing combustion, a maximum in-cylinder pressure Pmax during motoring is identified by an in-cylinder pressure sensor, and a crank angle θPmax corresponding to the maximum in-cylinder pressure Pmax is detected by a crank angle sensor. Further, a reference crank angle θPmaxtgt corresponding to the engine speed and the engine load factor is identified, and θPmax is corrected so as to become θPmaxtgt. Furthermore, the relation between a signal of the crank angle sensor and a crank angle (measured value) corresponding to the signal is corrected so that a measured value of the crank angle corresponding to Pmax becomes the post-correction crank angle.

摘要： An engine control apparatus includes a stack detecting unit, a count processing unit, a stack value storage control unit, and an abnormality determination unit. The abnormality determination unit determines that a sensor has a stack abnormality when a count value by the count processing unit becomes equal to or more than an abnormality determination threshold. When maximum value of the detected value of the sensor detected during a determination period is lower than a value stored in a storage unit and a stack state has not been detected by the stack detecting unit during the determination period, the count processing unit does not count up a counter and does not reset the counter.

摘要： An apparatus for determining an air-fuel ratio imbalance among cylinders based on an output value of an air-fuel ratio sensor, an imbalance determination parameter which becomes larger or smaller as a difference among air-fuel ratios becomes larger, and performs determining an air-fuel ratio imbalance among cylinders based on a result of a comparison between the imbalance determination parameter and a imbalance determination threshold. The determining apparatus calculates a purge correction coefficient which compensates for a change in the air-fuel ratio due to an evaporated fuel gas which is generated in a fuel tank, while the evaporated fuel gas is being introduced into an intake passage, and corrects a fuel injection amount with the purge correction coefficient FPG.
