The invention relates to a lubrication oil pump (1) for dosing a pre-settable amount of a cylinder lubrication oil (2) to a lubricating quill-opening of a cylinder of an internal combustion engine, in particular a two stroke large diesel engine. Said lubrication oil pump (1) comprising a housing (3) with a main hydraulic cylinder section (4) having a first axial end surface (5) and a second axial end surface (6), and further comprising a primary piston section (7) within the hydraulic cylinder section (4). According to the invention, the primary piston section (7) includes an injection bore (8) for receiving an injection piston (9) in such a way, that the injection bore (8) and the injection piston (9) arranged therein form a lubricating volume (V) for dosing the pre-settable amount of the cylinder lubrication oil (2) und are relatively movable with respect to each other along a cylinder axis (10). In addition, the invention relates to a cylinder lubricating arrangement and an internal combustion engine with
