ABSTRACT:
An early cylinder identification method and system using pulsewidth encoding are provided for use in a variable camshaft timing equipped engine. The method includes generating multiple signal pulses, each signal pulse having a unique length and being associated with one of the engine cylinders. The method also includes measuring the length of a signal pulse, and identifying the engine cylinder associated with the signal pulse based on the measured length of the signal pulse. A system includes a specially designed sensor wheel and control logic for performing the method.
