A signal plate for detecting revolutions, fitted to the camshaft, is provided with two signal generating means per cylinder; a cylinder identifying signal is added before said two signals; and two sensors are so arranged as to have a phase difference from the detection of said projection. Bit patterns are prepared from the outputs of these two sensors correspondingly to individual cylinders, and cylinder identification is accomplished according to the combination of these patterns. The phase difference here is so set that the number of signals detected by the second sensor (sub-crank angle sensor, hereinafter abbreviated SCAS), out of said two sensors, between signals detected by the first sensor (base crank angle sensor, hereinafter abbreviated to BCAS), can be one of three kinds. A signal from a BCAS signal input means is received, and the number of signals generated is measured by a signal counting means. Further a SCAS signal is received by a SCAS signal input means, and bit patterns are generated by a bit preparing means. Cylinder identification is performed according to a bit pattern for cylinder identification from a cylinder identification criterion storage means, another bit pattern generated by said bit preparing means and the number of signals generated by the signal counting means.

    摘要: When a throttle is fully open, a maximum torque set value is corrected based on the ratio between the maximum air volume set value under fully-open throttle conditions and the actual maximum air volume detected by an intake air volume meter such as an air flow sensor. Based on the corrected maximum torque set value, both the relation between the degree of accelerator opening and target torque and the relation between the target torque (target air volume) and the degree target throttle opening are corrected. Thus, even when various types of disturbances relating to torque error are generated, such as variations in air density generated in association with variations in temperature or altitude, variations over time such as contaminations of throttle chambers, or difference between machines such as engine bodies or auxiliary machines, it is possible to generate actual torque with respect to a target torque with a high degree of accuracy, while maintaining a desired relation between the degree of accelerator opening and the throttle opening.

    摘要: According to one embodiment of the invention, a purge quantity is controlled in proportion to an air quantity sucked into an internal combustion engine. During normal operation of the engine, a purge air-fuel ratio is calculated according to a purge rate and an air-fuel feedback control quantity. During transient operation of the engine, a target air-fuel ratio feedback control quantity is calculated according to the purge rate and the purge air-fuel ratio. When the difference between the air-fuel ratio feedback control quantity and the target air-fuel ratio feedback control quantity is greater than a predetermined value, the air-fuel ratio feedback control quantity is corrected to the target air-fuel ratio feedback control quantity. An undue fluctuation in air-fuel ratio of a fuel mixture supplied to cylinders occurring upon rapid fluctuation in purge rate can be suppressed.
