ABSTRACT:
The rotational position detecting apparatus for an internal combustion engine includes a rotational angle sensor outputting a rotation angle signal indicative of a rotational angle of the internal combustion engine, an in-cylinder pressure sensor outputting an in-cylinder pressure signal indicative of an in-cylinder pressure of a cylinder of the internal combustion engine, and a reference rotational position detecting section which detects a specific rotational angle of the internal combustion engine at which the in-cylinder pressure becomes a predetermined reference pressure under a predetermined running condition of the internal combustion engine, and determines the detected specific rotational angle as a reference rotational position of the internal combustion engine. The reference rotational position detecting section detects the specific rotational angle at least a predetermined number of times, and determines an average value of the detected specific rotational angle as the reference rotational position.
