    • The invention is directed to an ignition circuit for an internal combustion engine in a portable handheld work apparatus wherein a work tool is driven via a clutch. The ignition circuit includes an ignition time point control which connects a spark plug via a switch to a voltage source in order to trigger an ignition spark. The spark plug is mounted in the combustion chamber of the engine. This connection takes place in dependence upon the crankshaft angle and the rpm of the engine. In order to prevent damage to the clutch because of a blocked work tool, a test value counter driven via a rpm gate circuit is provided. The test value counter increments its value in the pregiven rpm window of the gate circuit with each rotation of the crankshaft and the content of the test value counter is compared to a pregiven limit value by a comparator. The output of the comparator activates a rpm-reducing protective circuit and the output of the comparator indicates reaching or exceeding the limit value.
    • 本发明涉及一种便携式手持式工作装置中用于内燃机的点火电路,其中通过离合器驱动作业工具。 点火电路包括点火时间点控制,其通过开关将火花塞连接到电压源以触发点火火花。 火花塞安装在发动机的燃烧室中。 这种连接取决于发动机的曲轴角度和转速。 为了防止由于工作工具被堵塞而对离合器造成损坏,提供了通过rpm门电路驱动的测试值计数器。 测试值计数器在曲轴的每次旋转时增加门电路的预定转速窗口中的值,并通过比较器将测试值计数器的内容与预定极限值进行比较。 比较器的输出启动减速保护电路,比较器的输出指示达到或超过极限值。
