Abstract

A two-stroke engine having a combustion chamber (3) configured in a cylinder (2) is disclosed. The combustion chamber is delimited by a reciprocating piston (5). The two-stroke engine includes at least one transfer channel (10, 11) configured in the cylinder and fluidly connecting the combustion chamber and a crankcase (4). The transfer channel is delimited by a set wall (19) with respect to the interior space (18) of the cylinder at least over a portion of its longitudinal extent. The set wall may be held with respect to the interior space of the cylinder by a device configured with the cylinder as one part. A method for manufacturing the two-stroke engine provides that the cylinder is produced in the pressure-cast die process and a set wall is pushed into the cylinder between the cylinder interior space and the transfer channels and is thereafter fixed via a holding element.
