ABSTRACT:
A detection system and method for determining the phase relationship between a crankshaft and one or more independently phase shiftable camshafts which the system integrates into camshaft and cylinder identification sensors for determining both cam location for variable cam phasing, and for generating a cylinder identification signal uniquely identifying one of the cylinders, for sequential fuel injection, thus reducing: (i) the number of sensors needed to operate the system to a single crankshaft sensor and a single sensor for each camshaft; and (ii) the number of high-speed inputs needed on the on-board engine control unit microprocessor. The number of sensing teeth on the independent cam wheels vary depending upon the number of cylinders and the number of independently phase shiftable camshafts in the engine. Each sensing tooth is associated with one of the engine's cylinders and one cam wheel contains an extra cylinder identification tooth associated with a selected cylinder.
