ABSTRACT:
A modular electronic ignition system for use in internal combustion engines is provided using latching Hall effect sensing devices. Two permanent magnets are affixed to a non-ferrous member mounted to the camshaft which extends through a seal in the timing cover. A sensing module comprising the Hall effect devices is arranged annularly or angularly about the magnet containing member and senses the magnetic field as the magnets pass the Hall effect devices. Dwell time is controlled by the angular distance at which the magnets are placed from each other. The output of the Hall effect devices drives application specific integrated circuits which provide low level switching of ignition coil primaries. The modular design allows for a low part count, a simplified EMI shielding arrangement, and easy removal and replacement of system components.
