Abstract: A two-stroke engine has a cylinder with a combustion chamber delimited by a reciprocating piston, wherein the piston drives in rotation a crankshaft, and wherein a spark plug projects into the combustion chamber and ignites a fuel/air mixture. The two-stroke engine further has devices for supplying fuel and combustion air to the combustion chamber and a control unit that determines the ignition timing based on an ignition map. The ignition map indicates the ignition timing as a function of the engine speed for at least one first and one second operating states and for at least one first and one second engine speed ranges. The engine is controlled in that for an engine cycle the ignition timing is set in the second operating state at least within the first engine speed range based on the engine speed and on the number of engine cycles since the last combustion.

A controller in the ignition circuit determines the state of the stop switch by evaluating signals on the state of the internal combustion engine, corresponding information data is generated, and a corresponding stop flag is set and/or enabled. Depending on this information, the activation of the ignition switch, that controls ignition spark, is either blocked or enabled by the controller.

Abstract: An electrical ignition for internal combustion engines having coils and a magnetic generator that rotates synchronously with the engine. The generator's magnetic field passes periodically through the coils and induces a sequence of corresponding alternating-voltage half-waves.
