An ignition device for a motor unit with an internal combustion engine provided with a piston, a combustion chamber with a spark plug, a crankshaft driven by the piston, an intake port supplying combustion air to the combustion chamber, an exhaust for removing combustion gases from the combustion chamber, a signal generator driven by the crankshaft and emitting for one crankshaft revolution an alternating voltage signal, has an ignition unit that triggers a spark at the spark plug at a preselectable timing. The ignition unit is a module separate from the motor unit. An alternating voltage signal generated by the signal generator is supplied to the ignition unit as an information signal sufficient for operating the internal combustion engine. The alternating voltage signal is supplied to a first unit for energy processing and to a second unit for processing information for control of the internal combustion engine.
An ignition device for a motor unit comprising an internal combustion engine, wherein the internal combustion engine of the motor unit comprises a piston, a combustion chamber with a spark plug, a crankshaft that is driven in rotation by the piston, an intake port for supplying combustion air into the combustion chamber, an exhaust for removing combustion gases from the combustion chamber, an alternator that is driven in rotation by the crankshaft and attached to the motor unit, wherein the alternator supplies electric energy to electric consumers and, for one crankshaft revolution, emits sequential alternating voltage signals;
