发明名称 Portable hand-held power tool having a data connection for diagnostic purposes
摘要 A power tool has a drive unit arranged in a tool housing. The drive unit has an internal combustion engine with a cylinder provided with a combustion chamber. A spark plug is arranged at the cylinder. A piston is connected to a crankshaft and reciprocates within the cylinder and delimits the combustion chamber. A central control unit controls the drive unit and has a microprocessor and an ignition control unit, wherein the central control unit is connected by the ignition control unit to the spark plug and triggers a spark at the spark plug as a function of a rotary speed of the crankshaft at an appropriate ignition timing. A data storage device is connected to the central control unit. An energy supply unit provides electric energy. An interface enables, from outside the tool housing, external data access to data of the central control unit.
