ABSTRACT:
An improved engine ignition system for a marine engine or the like, which provides reliable start-up capability and running protection. The system detects the actual rotational speed of the engine and provides an electrical signal that is proportional to the measured speed, and selectively advances the ignition timing characteristic, and also controls overall engine speed to prevent engine damage that may be caused by an overspeed condition. The system advances the ignition timing characteristic during warm-up until a predetermined temperature is achieved, and also advances the ignition timing characteristic for a predetermined time period during initial running. The system utilizes the power of the battery during start-up to supplement the power that is generated by the stator coil which normally supplies all of the necessary power for the control circuitry of the ignition system.
