FIELD: engine building.
SUBSTANCE: invention relates to the engine building. Cylinder-piston group of marine crosshead low-speed motor (LSM) contains cylinder bushing (1) with piston (2), in corresponding grooves of which there are piston rings. Stem (4) connects piston (2) with dross (7) and is located with possibility of movement in hole of horizontal partition (9). Partition (9) is located below cylinder bushing (1). At the same time rod (4) consists of two parts with possibility of disassembly, wherein length of lower part of rod (4), which it is connected to LSM slider (7), is greater than height of piston (2) to height of piston ring. On inner surface of partition (9) there are projections arranged along circumference, diameter of which is equal to inner diameter of cylinder bushing (1).
EFFECT: technical result consists in improvement of engine repairability.
