(54) Two-stroke combustion engine cylinder


(57) The access to the internal areas (6) of closed transfer ports (4, 4a) and their edges (11, 11a) is solved to allow the precise working and the checking of channel shape precision in the two-stroke combustion engine cylinder.
This is achieved if the cylinder is arranged of the upper and lower bodies (1 and 2) while the separating plane (7) of both bodies (1 and 2) is placed between the upper edge (9) of the exhaust channel (10) and the lower edges (11) of the side closed transfer ports (4). Both bodies (1 and 2) can be connected by either a demountable method (by means of screws) or a fixed arrangement (e.g., by bonding, welding, etc.).
