ABSTRACT:
A cylinder discriminating device includes a ratio computing device for computing the ratio between the periods of signal generation over predetermined two sections, a signal group discriminating device for discriminating a predetermined group of signals, and a signal discriminating device for discriminating a predetermined signal from the group of signals. Thus, the cylinder discriminating device can be provided which does not provide erroneous decision in cylinder discrimination in a signal generating device in a single system, but can shorten the time required for cylinder discrimination to effect inherent control for each cylinder.
