    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 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: The invention relates to a method and a device for bi-directional single-wire data transmission of information between a control device (2) and at least one peripheral device (3). The inventive method comprises the following steps: generating a first current flow from the control device (2) to the peripheral device (3) during first windows of time via a single-wire line (4) for transmitting a voltage-coded or current-coded piece of information from the control device (2) to the peripheral device (3); and/or generating a second current flow from the peripheral device (3) to the control device (2) during second windows of time via the single-wire line (4) for retransmitting a voltage-coded or current-coded piece of information from the peripheral device (3) to the control device (2); whereby the first and second windows of time do not overlap; and/or generating information that should be additionally transmitted or retransmitted in first and/or second windows of time and that is transmitted as digital or as analog signals by modulating the current or the voltage of the single-wire line (4) and that are evaluated in the control device (2) or the peripheral device (3).

    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.
