Abstract
A cylinder identification device has an intake cam sensor and an exhaust cam sensor which output signals indicative of a rotation angle of the camshaft. The levels of the output signals are varied according to the rotation angle of the crankshaft. The cylinder identification is conducted based on an order of combination variation of the output signal levels. The changing positions of the output signal levels of at least one of the intake cam sensor and the exhaust cam sensor are arranged in such a manner to correspond to positions or right before positions in which the fuel can be initially injected at the time of the engine starting. Thus, the cylinder identification device can identify the initial cylinder in a short period, into which the fuel is initially injected at the time of the engine starting, whereby the startability of the engine is enhanced.
