摘要： A hand-held power tool comprising an internal combustion engine (4), a working tool (6), a centrifugal clutch (8), and a control system (10) is disclosed. 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). The control system (10) is configured to deactivate the speed limitation controller (14) upon sensing at least one acceleration at a level above the limitation speed and sensing at least one deceleration at a level above the limitation speed, such that the engine (4) is rotatable above the limitation speed to drive the working tool (6).

摘要： A maximum value of a discharge current from a capacitor 13, detected by a primary-side current detection means 24 disposed at a grounded end of the capacitor 13, is controlled such as not to exceed a predetermined first control value Y1. The first control value Y1 is derived based on magnetic saturation of a primary winding 3, with the control being performed by controlling the on-off state of an energy injection switching means 20. As a result, magnetic saturation of the primary winding 3 can be prevented, and the reliability of an ignition apparatus which incorporates an energy injection circuit 6 can be increased.

摘要： When a normal operation is detected by a self-interruption signal source and a first transistor is on, if an on-signal is inputted to an IN terminal, a second transistor is turned on and a third transistor is turned off. Accordingly, an IGBT is turned on. In this state, if an abnormality is detected by the self-interruption signal source, the second transistor is turned off and the third transistor is turned on. Accordingly, a gate terminal of the IGBT is connected to an emitter terminal via the first and third transistors, and charges accumulated by gate capacitance of the IGBT are rapidly discharged. Consequently, if a comparator detects that a collector voltage of the IGBT has exceeded a predetermined voltage, the first transistor is turned off, and gradual interruption in which the charges accumulated by the gate capacitance are gradually released by a resistor is performed.

摘要翻译： 当通过自我中断信号源检测到正常操作并且第一晶体管导通时，如果导通信号被输入到IN端子，则第二晶体管导通并且第三晶体管截止。 相应地，IGBT导通。 在这种状态下，如果自我中断信号源检测到异常，则第二晶体管截止并且第三晶体管导通。 因此，IGBT的栅极端子经由第一晶体管和第三晶体管连接到发射极端子，并且由IGBT的栅极电容累积的电荷被快速放电。 因此，如果比较器检测到IGBT的集电极电压已经超过预定电压，则第一晶体管截止，并且由栅极电容累积的电荷通过电阻器逐渐释放的逐渐中断被执行。

摘要： An ignition system and a method for inhibiting ignition spark discharge at a spark gap at an inappropriate point in time are proposed. The method is characterized by the detection of spark breakaway and/or failed ignition and, in response thereto, by the generation of a conductive path by an ignition spark at the spark gap at an appropriate point in time.

摘要： A safety system for engine powered machinery having a fuel cut functionality to promote more rapid shutdown of the rotating parts of the engine powered machinery. In one aspect, the system is implemented as a wiring harness disposed exclusively on the engine which simultaneously disables one or more ignition coils and prevents a fuel-air mixer from supplying a mixture of air and fuel to the engine upon activation of a safety switch. In alternate aspects, the system further comprises a stator brake which is activated by the safety switch to provide additional braking torque on the engine. These features bring the machinery to a rapid halt, further enhancing safety.
