摘要： A two-stroke engine has a cylinder wherein a piston is journalled for reciprocating movement. The piston delimits a combustion chamber configured in the cylinder. The engine has an outlet from the combustion chamber and a transfer channel which opens at an inlet opening into the crankcase and at a transfer window in the combustion chamber. The piston drives a crankshaft via a connecting rod. The crankshaft is rotatably journalled in the crankcase. At least one control element for the inlet opening is connected to the crankshaft so as to rotate therewith.The control element is so arranged that the inlet opening is at least partially closed thereby in at least one operating state of the engine during the downward stroke of the piston at least 5° crankshaft angle after the opening of the transfer window.
