A cylinder identifying apparatus comprising a crank angle sensor detecting a crank angle of a combustion engine having a plurality of cylinders, a cylinder identifying means identifying a cylinder to be controlled by an output signal from the crank angle sensor , a cranking judging means detecting a cranking state of the combustion engine , and an erroneous cylinder identification preventing means detecting starting of cranking of the combustion engine by an output from the cranking judging means, and circumventing the cylinder identification by the cylinder identifying means until a predetermined time passes after starting the cranking, whereby the cylinder to be controlled is securely identified at time of cranking, and erroneous detection, erroneous control, and detection delay are prevented.
