Internal combustion engine i.e. single cylinder two-stroke engine, operating method, involves controlling engine in operating state that is high rotational speed range, in which rotational speed of engine lies above nominal rotation speed

摘要

The method involves providing an electromagnetic valve (18) for supplying fuel and combustion air and an ignition module (20) for ignition of mixture in a combustion chamber (5). An internal combustion engine i.e. two-stroke engine (1), is controlled in an operating condition such that number of burns is less than number of engine cycles. The operating state is a high rotational speed range, in which rotational speed of the engine lies above nominal rotation speed and below a number of revolutions in a regulation range.
