The ion current detecting means includes a plurality of ion current detecting circuits for detecting ion currents in the engine cylinders belonging to a plurality of cylinder groups. The engine cylinders belonging to each cylinder group are so selected as not to be controlled in succession for ignition.

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.
