A combustion chamber (12) is formed in a cylinder (11) of the engine (10) and is delimited by a piston (13) which drives a crankshaft (14) in rotation. A spark plug (16) is held in the cylinder (11) and is driven by an ignition module (20) to ignite a compressed air/fuel mixture in the combustion chamber (12) to drive the piston (13). A short circuit line (21) is provided on the ignition module (20) for switching off the ignition. The short circuit line (21) is configured as a bus line (30) in order to make available, in a simple manner, a plurality of further operating parameters to the ignition module. An external control apparatus (23, 24) and/or sensors (25, 26) are connected to the bus line (30).

摘要： 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.
