ABSTRACT:
A solid-state, push rod actuated breakerless ignition system is disclosed that is particularly suitable for use as original equipment or an after market upgrade for many industrial engines of the type having a cam-operated push rod actuated ignition. The apparatus includes a base for mounting to the engine, a rocker arm movably mounted to the base for periodic actuation by the cam lobe and having a first transducer element fixably located thereon for movement in an arm path, a second transducer element mounted in predetermined relation to the base proximate the arm path, and a circuit for producing an electrical trigger signal in response to the movement of the first transducer element to a predetermined spatial relation with the second transducer element, the combustion being initiated in response to the trigger signal.
