摘要： To create an internal combustion engine including a crankcase and a cylinder, wherein a piston is guided in the cylinder to perform a stroke movement and movably defines a combustion chamber, and wherein at least one transfer channel, through which ignition mixture is guided from the crankcase into the combustion chamber, is arranged in the cylinder, which leads to a further improvement of the exhaust gas quality and/or of the fuel consumption, in particular for creating an improved metering of ignition mixture into the fuel chamber, it is proposed for the piston to encompass a lower piston edge, which interacts with at least one counter body such that an inlet cross section of the transfer channel for the inflow of the ignition mixture from the crankcase into the transfer channel can be controlled by the stroke movement of the piston by the lower piston edge.
