The engine (4) has a clutch-in speed, above which the engine (4) drives the working tool (6). The control system (10) comprises a rotation speed sensor (12), and a speed limitation controller (14), which is configured to limit an engine speed at a limitation speed below the clutch-in speed. It is active or activated during a starting procedure of the internal combustion engine (4).

摘要： In at least some implementations, an ignition system for a light-duty combustion engine includes a charge winding, a microcontroller and a power supply sub-circuit. The sub-circuit is coupled to both the charge winding and the microcontroller and includes a first power supply switch, a power supply capacitor and a power supply zener. The sub- circuit is arranged to turn off the first power supply switch so that charging of the power supply capacitor stops when the charge on the power supply capacitor exceeds the breakdown voltage on the power supply zener. In at least some implementations, the power supply capacitor may power the microcontroller and the power supply sub-circuit may limit or reduce the amount of electrical energy taken from the induced AC voltage of the charge winding to a level that is still able to sufficiently power the microcontroller yet saves energy for use elsewhere in the system.

摘要： Ignition systems of the kind used to ignite a difficult-to-ignite fuel oil by using energy stored in a capacitor at a breakdown for creating an ignition arc at the electrodes of a spark plug, designed to preclude interference of contaminants with conduction of an ignition arc across an established current path between the electrodes of the spark plug. An air gap and a sparkplug are connected in series, wherein the sparkplug produces an ignition arc in a fuel to be ignited. A first high voltage power supply develops a first direct current voltage across the capacitor, which is supplied as a voltage across the air gap and the spark plug. A second high voltage power supply supplies a second pulsed voltage across the air gap and the spark plug, wherein thesecond pulsed voltage is substantially higher than the first direct current voltage, and the second pulsedvoltage jumps the gap of the air gap and thus initiates an ignition arc, and the first direct current voltage is current limiting thereby allowing the capacitor voltage to approach zero, and thus allowing the air gap to cease conducting, thereby allowing the cycle to repeat itself. A diode is positioned between the second pulsed voltage and the capacitor of the first high voltage power supply to isolate the capacitor from the second pulsed voltage.
