Abstract: Ignition system for an internal-combustion engine, in particular for use in a chain saw or the like, comprising a magnetically conducting core supporting a charging winding and a triggering winding, a flywheel having at least one magnetic field generating member and adapted to cooperate with the magnetically conducting core to cause, when passing, voltages to be induced in the windings, and an electronic switch means adapted to trigger, in response to a trigger pulse generated by the triggering winding, the discharge of a capacitor, which has been charged by a voltage generated in the charging winding, via the primary of an ignition coil the secondary of which comprises a spark plug. The ignition system comprises an additional winding which is provided and disposed so that during its normal rotational movement the flywheel first passes said additional winding before turning in over the legs of the magnetically conducting core, the voltage induced in the additional winding being used to prevent trigger pulses from reaching the switch means if the direction of rotation of the engine is the opposite to the normal one.

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.

Abstract: An electronic ignition system replacing corresponding stock circuitry but utilizing the stock magneto and ignition coil provided with the engine of a sport vehicle, such as a jet ski or snowmobile, to provide improved performance. A timing circuit is provided as part of the ignition circuitry to enable a trigger pulse of a predetermined duration to be delivered to the ignition coil and further, to inhibit subsequent trigger pulses limiting the engine speed below a determined rpm limit. The timing circuitry uses an over-temperature switch connecting a capacitance to lengthen the inhibit time period reducing the maximum rpm limit. A holeshot switch connected across the over-temperature switch lowers the rpm limit while the throttle is held in the full speed position. Compensated pickup circuitry, automatic battery connect/disconnect, low impedance kill switch circuitry and an impedance protected tachometer output is provided to enhance the performance and features of the ignition systems of sport vehicles.

Abstract: An ignition method and system for internal combustion engines, especially in lawn mowers or chain saws, in which a magneto induces a plurality of alternating voltage half-waves for each engine revolution to charge an energy-storing element and to discharge it by a switch controlled by the primary coil of an ignition transformer. The switch is actuated when the first half-wave of each revolution reaches a trigger threshold. The ignition system induces the charging alternating voltage dependent upon the rotary position of the engine for the energy storage element and for discharging it via the switch for firing the spark synchronously with the alternating voltage. The system has a timer module which responds to the alternating voltage by producing a signal to block the ignition switch for the duration of a time interval which corresponds to a top speed limit of the internal combustion engine.

Abstract: An electronic ignition module for an internal-combustion engine that is supplied with sparking energy from a rotating magnet includes a switchable semiconductor device through which current in the primary of an ignition coil is to be conducted. A portion of a circuit in the module senses a time when voltage across the semiconductor device approaches a maximum value, and produces a signal at that time that switches the semiconductor device out of conduction. A positive-feedback circuit is connected to increase the switching speed of the semiconductor device. The semiconductor device is protected against AC voltages of a polarity opposite to that of the conducting direction of the semiconductor device, and is caused to advance switching time in response to increased voltages associated with high engine speed. A temperature-sensitive resistor performs temperature compensation on the module in response to the temperature of a hot engine to permit restart of the engine if it is stopped briefly.

Abstract: An engine igniter has a reference signal coil which generates an advance-side reference signal and a lag-side reference signal during a half-cycle of the alternating current output of a generator. An ignition timing control circuit determines the direction of rotation of the engine based on the polarity of the alternating current when the reference signals are generated. The ignition timing control circuit controls the ignition timing of an ignition circuit, using the lag-side reference signal as a reference at low engine speeds and using the advance-side reference signal as a reference at high engine speeds. When the engine begins to rotate in reverse, the ignition timing control circuit prevents ignition and stops reverse rotation.

Abstract: An engine ignition control system comprising an ignition circuit of capacitor charge-discharge type is disclosed in which the ignition timing is determined by controlling the charge-discharge cycle of a capacitor by an output signal from an engine speed detection circuit. An overspeed control circuit stops the ignition when a detection output signal of the engine speed detection circuit exceeds a reference voltage level corresponding to a set engine speed. A slowing down control circuit is actuated in response to an engine slowing down operation start switch for realizing a hypothetical condition substantially equivalent to the one in which the engine speed detection circuit detects an engine speed higher than the actual engine speed thereby to accomplish engine slowing down operation by (a) increasing the reference voltage level gradually, or (b) increasing the output signal level of the engine speed detection circuit stepwise.

Abstract: An ignition system for four cycle engines generates a first pulse when the crankshaft revolves by a first setting angle from a base position. The second pulse is generated when the crankshaft revolves to a second setting angle which is larger than the first setting by the angle difference between cylinders. The third pulse is generated at the position of a third setting angle which is between the first setting angle and the second setting angle in the position of the crankshaft when the crankshaft revolves twice. The generation of the first and second pulses is stopped or inhibited during the generation of the third pulse, allowing the first pulse to fade away.
