用于运行带有内燃机的手持式工作器械的方法
摘要：
本发明涉及一种用于运行带有内燃机的手持式工作器械的方法，手持式工作器械具有内燃机(8)，其经由离心力离合器(24)驱动工作器械的至少一个工具。离心力离合器在下接合转速(nu)与上接合转速(no)之间延伸的接合转速范围(nK)中接合。内燃机(8)具有燃料供应装置、点火装置、控制装置(41)和用于检测内燃机(8)的转速(n)的器件。用于运行手持式工作器械的方法设置成，内燃机(8)的转速变化过程在接合转速范围(nK)中被监控且当转速变化过程在规定的时间段(Δt)上与规定的转速变化过程一致时将发出用于驱动工具的在运行功率(P1)中的功率(P)提高到提高的功率(P2,P3)上。
摘要（英）：

A handheld work apparatus has a combustion engine which drives a tool of the work apparatus via a centrifugal clutch. The centrifugal clutch couples in an engagement rotational speed range (nK) which extends between a lower engagement rotational speed (nu) and an upper engagement rotational speed (no). The engine has a fuel supply device, an ignition device, a control device and a device for detecting the rotational speed (n) of the engine. A method for operating the handheld work apparatus makes provision for the rotational speed profile of the combustion engine to be monitored in the engagement rotational speed range (nK) and for the power (P) output for driving the tool to be increased from an operating power (P1) to an increased power (P2, P3) when the rotational speed profile corresponds with a predetermined rotational speed profile over a predetermined period of time (Δt).
