ABSTRACT:
An improved feedback control system for an engine that employs only a single sensor associated with only one cylinder of the engine. Cylinder-to-cylinder adjustments are made based upon measurement of the differences in crankshaft speed during a portion of the compression stroke for each cylinder so as to provide an accurate indication of air flow to the individual cylinders.
