摘要： A compression detection apparatus for determining which one of a pair of phase-opposed cylinders is under compression has a capacitive probe coupled to both ends of the secondary winding of an ignition coil servicing both spark plugs of the pair of cylinders. Phase and magnitude of the voltage signal appearing on the capacitive probe line are processed by a single comparator for determining which on of the pair of cylinders is under compression.
