ABSTRACT:
The absolute angular position of an internal combustion engine is determined by monitoring engine intake manifold pressure at a strategic position in the manifold affected most significantly by the intake event of a predetermined cylinder. A significant or maximum depression in manifold pressure over each engine cycle then is indicative of the intake stroke of the predetermined cylinder.
