Estimating the term…
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.
An internal combustion engine comprising a crankcase and comprising a cylinder, wherein a piston is guided in the cylinder so as to be able 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, characterized in that the piston encompasses an upper 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 means of the stroke movement of the piston by means of the lower piston edge.
A method for operating an internal combustion engine comprising a crankcase and comprising a cylinder, wherein a piston carries out a stroke movement in the cylinder and thus 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, characterized in that the piston is embodied with a lower piston edge, which interacts with at least one counter body, so that an inlet cross section of the transfer channel is controlled by means of the stroke movement of the piston by means of the lower piston edge for the entry of the ignition mixture from the crankcase into the transfer channel.
