ABSTRACT:
A transmitting device is operative for transmitting a rotational force from a crankshaft to a camshaft. A rotational phase adjusting device is operative for adjusting a relative rotational phase between the crankshaft and the camshaft. A crank angle sensor is operative for detecting a rotational angle of the crankshaft, and outputting a rotational angle detection signal indicative thereof. At least one signal inducing member is provided on the camshaft. A cam angle sensor cooperating with the signal inducing member is operative for outputting a cam signal each time the camshaft reaches a predetermined rotational angle. A phase controlling device is operative for monitoring a phase difference between the cam signal and the rotational angle detection signal determined while an arbitrarily-chosen angle of the crankshaft is used as a reference, and for determining an amount of the adjustment by the rotational phase adjusting device so that the monitored phase difference will be equal to a target value. A cylinder discriminating device is operative for setting a discrimination angular range with respect to the rotational angle detection signal outputted by the crank angle sensor. The discrimination angular range is smaller than an angle of 360 degrees of the crankshaft and greater than at least an angular range corresponding to a range of the phase adjustable by the rotational phase adjusting device. The cylinder discrimination device is also operative for discriminating cylinders on the basis of a presence and an absence of the cam signal synchronous with the discrimination angular range.
