ABSTRACT:
A trigger system for spark-fired internal combustion engines includes a plurality of magnets mounted in a structure that rotates in a timed relationship with the engine. One magnet is provided for each cylinder in the engine. All of the magnets except one have the same pole face exposed to couple inductively with a sensing coil, while the remaining magnet has an exposed pole of opposite polarity. The sensing coil is doubly wound and the resulting two coils are connected in opposite senses. The outputs of the two coils are taken to a decoding unit which produces an output of one pulse per magnet. Those pulses are substantially identical, regardless of magnet polarity, and are used to fire the spark plugs at the appropriate times. The decoding unit also produces a unique pulse which identifies the magnet of opposite polarity. That pulse is used to identify a selected cylider in the engine, such as the No. 1 cylinder. In this manner, the firing of all of the spark plugs, and the identification of the cylinders, are controlled using a single magnet for each cylinder.
