Abstract

At least one transfer channel (9, 29) is formed in the cylinder wall (4, 24) of the cylinder (1, 21) for a two-stroke engine. The transfer channel (9, 29) is closed to the cylinder outer side (5, 25) by a cover (10, 30). The method for making the cylinder (1, 21) provides that the cover (10, 30) is assembled in a first step on the cylinder (1, 21) and, in a second step, the cylinder bore (3, 23) is machined.
