摘要： A control system for a low cost, light duty combustion engine, where the control system generally utilizes an engine speed input signal and independent operating sequences to determine a desired ignition timing. There are several independent operating sequences, each one of which is designed to optimally control the engine under certain conditions. These operating sequences include a Cranking sequence, a Warm Up sequence, a Normal Mode sequence, an Acceleration sequence, a Come Down sequence, a Recovery Bump sequence, and a Part Throttle sequence. During idling conditions, the Normal Mode sequence uses rapid changes in the ignition timing to maintain the engine speed in a small, idle engine speed range. By utilizing these operational sequences, the control system improves the performance of a low cost, light duty engine across a wide array of conditions.

摘要： A kill-switch control circuit for use with a light-duty combustion engine determines whether to execute a controlled shut down method or an immediate shut down method in response to kill-switch activation. The selection of a shut down method is made, at least in part, by using engine speed readings and by counting engine revolutions. The controlled shut down method utilizes ignition timing delay and/or spark ratio techniques to quickly bring the engine to a stop, yet does so in a controlled manner that avoids backfiring and other undesirable effects. Conversely, the immediate shut down method abruptly stops sending a current to the spark plug.

摘要： A controlled slow down apparatus and method for use in the event that a light-duty combustion engine has entered a state of excessive speeds or auto-ignition. The controlled slow down method is preferably initiated when the engine speed exceeds an activation speed for a predetermined number of engine revolutions. Once initiated, the controlled slow down method uses a combination of ignition timing and spark ratio manipulations in order to disrupt the auto-ignition conditions and slow down the engine in a controlled manner. Preferably, the controlled slow down method is only one part of an overall ignition control method, and can be incorporated within or utilized by one of a number of different ignition timing methods known in the art.

摘要： A method and system for operating an engine wherein ignition of the engine is activated according to a predetermined timing schedule that references engine speed, and the ignition is suppressed above a predetermined engine speed threshold to allow engine speed to fall below the predetermined engine speed threshold. Thereafter, ignition is reactivated according to timing that is retarded relative to the predetermined timing schedule for a predetermined number of engine revolutions substantially when the engine speed has fallen below the predetermined engine speed threshold, thereby mitigating undesirable spikes in combustion chamber maximum pressure.

摘要： A capacitor discharge engine ignition system that includes an ignition coil having a primary winding and a secondary winding for coupling to an engine ignition spark plug. A first electronic switch has primary current conducting electrodes in circuit with an ignition charge storage capacitor and the primary winding of the ignition coil, and a control electrode responsive to trigger signals for operatively connecting the ignition charge storage capacitor to discharge through the primary winding of the ignition coil. A charge/trigger coil arrangement generates periodic signals in synchronism with operation of the engine. The charge coil generates a charge signal to charge the ignition charge storage capacitor, while the trigger coil generates a trigger signal for triggering discharge of the capacitor through the ignition coil. An electronic circuit for controlling timing of the trigger signal as a function of engine speed includes a second electronic switch having primary current conducting electrodes operatively connected to the control electrode of the first electronic switch, and a control electrode. An RC circuit, including a resistor and a capacitor, is operatively connected to the charge coil and the control electrode of the second electronic switch to prevent application of the trigger signal to the control electrode of the first electronic switch during occurrence of the charge signal, and thereby controlling timing of application of the trigger signal to the control electrode of the first electronic switch as a function of engine speed.
