Claim:
A portable handheld work apparatus comprising: a work tool; an internal combustion engine for driving the work tool; said engine including a crankshaft; said engine further including a cylinder and a piston conjointly delimiting a combustion chamber for driving said crankshaft in rotation; an ignition module; a spark plug connected to said ignition module and held in said cylinder to deliver an ignition spark to a compressed air/fuel mixture in said cylinder when driven via said ignition module at an ignition time point in a predetermined crankshaft angular position to ignite said compressed air/fuel mixture to drive said piston; a short circuit line connected to said ignition module for switching off the ignition; said short circuit line being configured as a bus line; a plurality of components connected to said bus line; and, said ignition module being a master for controlling the data traffic on said bus line so as to permit a data communication only when a pregiven minimum crankshaft angular distance (A, B) is present at an ignition time point (Z 1 , Z 2 ) determined by said ignition module.
