Abstract
A two-stroke engine having a combustion chamber ( ) configured in a cylinder ( ) is disclosed. The combustion chamber is delimited by a reciprocating piston ( ). The two-stroke engine includes at least one transfer channel ( ) configured in the cylinder and fluidly connecting the combustion chamber and a crankcase ( ). The transfer channel is delimited by a set wall ( ) with respect to the interior space ( ) 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.
