Two-Stroke Engine

A two-stroke engine comprising:

• a cylinder with a combustion chamber disposed therein;
• a piston reciprocatingly supported in the cylinder and delimiting the combustion chamber;
• a crankshaft rotatably supported in a crankcase and driven by the piston;
• at least one transfer passage connecting the crankcase in at least one position of the piston with the combustion chamber, wherein the transfer passage has a piston-controlled transfer port that opens into the combustion chamber and an opening that opens into the crankcase;
• a mixture inlet that opens into the crankcase;
• an outlet provided at the combustion chamber;
• wherein the transfer port and the opening are displaced relative to each other in a circumferential direction of the cylinder;
• wherein at least one wall section of the transfer passage forms an undercut when viewed from the crankcase in a direction of a longitudinal cylinder axis of the cylinder;
• wherein the at least one wall section is delimited by a separate component that is inserted into the cylinder from a side facing the crankcase.
