The ignition system for providing spark ignition to the cylinders of an internal combustion engine includes a generator assembly adapted to be mounted on said engine. This generator assembly includes a magneto adapted to be driven in response to the operation of the engine to provide output power and a timing unit including at least one rotatable unit driven in timing relationship to the operation of said engine. A control assembly is removably mounted on the generator assembly and incorporates an ignition control circuit connected to receive power from the magneto and operative in response to the timing unit to provide spark ignition to specific cylinders of the internal combustion engine. The control assembly is removable from the generator assembly without altering the timing relationship between rotatable unit and engine.

Modular, programmable high energy ignition system

The ignition control box assembly is adapted to be retrofit onto an internal combustion engine and to maintain a hose for the engine against movement in all directions while providing electrical shielding for transformer assemblies mounted within the control box. A metallic chamber wall is formed integrally with back, top and bottom walls for an open sided housing, and extends from the backwall into the housing to form two separate compartments. The compartments are electrically shielded by two spaced metal walls formed by the chamber wall and the air gap provided by an open ended chamber defined by the chamber wall which extends angularly and vertically across the housing. The open side of the housing is closed and sealed by a removable closure assembly.

Ignition control box assembly for internal combustion engine

The overspeed ignition system includes trigger means operative in timed relation to the speed of an internal combustion engine. A controlled switching means operates under the control of the trigger means to pass pulses of energy to a spark ignition unit. An overspeed cutout assembly is provided between the controlled switching means and the spark ignition unit to sense the time interval between the pulses of energy passed by the controlled switching means. When this time interval is less than an internal timed lockout interval determined by the overspeed cutout assembly, the cutout assembly blocks the pulses of energy to the spark ignition unit. The trigger means is formed by a trigger pulse generating assembly having a rotor of circular cross section symmetrically mounted for rotation relative to at least one trigger coil. The rotor is differentially magnetized to prevent pulses of energy from passing to the spark ignition unit when the engine rotates in a reverse direction. This rotor is part of a novel flux conducting flywheel unit which forms part of the flux path for the rotor to enhance the pulse generating capability of the trigger pulse generating assembly.

Overspeed ignition system

An ignition system for use with spark ignited engines wherein the ignition system is compact and mounted beneath the associated flywheel. The ignition system includes a manually actuated timing ring for manually advancing the firing point, and includes a rotor essentially in the form of a spiral having a discrete discontinuity on its periphery for providing enhanced safety features.

Breakerless ignition control system

An electronic ignition control system including one coil assembly having a high number of turns to charge the associated capacitors to a desired level when the speed of the engine is low, and another coil assembly having a low number of turns to charge the capacitors to a desired level when the speed of the engine is high to thereby provide energy at a suitable level to fire the associated spark plugs. The system also includes means for regulating the voltage supplied by the alternator coils to a battery and thus preventing the battery from overcharging; and, means are provided for driving a tachometer proportionally to the firing pulses supplied to the spark plugs.
