摘要： A cylinder identifying apparatus for an internal combustion engine including a rotary signal generator, a measuring device, a calculating device and an identifying device. The rotary signal generator generates, in synchronism with a rotation of the engine, a signal having first positional pulses, each corresponding to one of a plurality of cylinders of the engine, and a second positional pulse corresponding to a specific one of the cylinders. The measuring device measures the time periods between the beginning of each contiguous pulse, as well as the time periods representing the width of each of the pulses. The calculating device then calculates ratios of each of the time periods representing the widths of the pulses to their corresponding time period of the time periods representing the time between the beginning of each contiguous pulse. These ratios are then normalized. The identifying device then identifies one of the cylinders by comparing the normalized values to a reference value, and then is able to identify the other cylinders because the sequence of the cylinders is known.

摘要： An internal combustion engine control apparatus for performing the timing control such as ignition and fuel injection timing control with high accuracy even in a transient operation state such as acceleration or deceleration. A ratio between a first interval period extending from a first reference position to a second reference position and a second interval period extending from a second reference position to the first reference position is determined. A correcting coefficient is calculated on the basis of the ratio. By using this correcting coefficient, the predicted reference position period is calculated, on the basis of which the timing control is performed.
