Abstract

The invention relates to a method for producing a cylinder (10, 110) for a two-stroke engine, comprising the following steps: producing a casting core (30, 130), wherein a central core slide (31, 131) for the cylinder chamber (11, 111) and at least one salt core (33, 133) for an overflow channel (18, 19; 118, 119) are produced and the at least one salt core (33, 133) is connected to the central core slide (31, 131), inserting the casting core (30, 130) into a casting mold, casting the cylinder (10, 110) in a die-casting process, removing the central core slide (31, 131) from the cylinder (10, 110), wherein the at least one salt core (33, 133) is separated from the central core slide (31, 131), and flushing the at least one salt core (33, 133) out of the cylinder (10, 110). The invention further relates to a casting core (30, 130) for such a method.
