ABSTRACT:
A crank angle detecting apparatus for an internal combustion engine. A crank rotor rotates integrally with the engine crankshaft, and the crank rotor is marked with a pattern of indicia. Certain indicia demarcate a number of equal segments into which the crankshaft rotor is divided. Other indicia uniquely identify each segment. In one embodiment, no two adjacent segments have the same pattern of segment-identifying indicia. In another embodiment, no three adjacent segments have the same pattern of segment-identifying indicia. A detector senses the indicia as the indicia pass by the detector. A cam rotor rotates integrally with the engine cam shaft. The cam rotor is also marked with indicia, and a detector is positioned to detect the cam rotor indicia as they pass by. Based on signals from the detector, an ECU can determine the position of the crankshaft with respect to the engine cycle.
