Method for operating two-stroke engine

The invention relates to a method for operating a two-stroke engine, wherein the two-stroke engine has a cylinder and a crankcase. A combustion chamber bounded by the piston is formed in the cylinder. The piston drives rotation of a crankshaft rotatably disposed in a crankcase. An electromagnetic fuel valve is provided that controls an amount of fuel supplied into the intake passage via the outlet opening. In order to control the fuel valve, a control device is provided. The quasi-stationary state of the two-stroke engine is a state in which the throttle element shifts less than 10% of the maximum shift amount of the throttle element within a crankshaft angle of 360 degrees. According to the invention, the control of the fuel valve after the start-up process is carried out in the quasi-stationary state in such a way that the fuel valve is opened and closed just once in each group for uninterrupted successive groups of successive turns of the crankshaft. Here, each group comprises 2 to 20 turns of the cranksha
