<p>A cylinder lubricating device (1) for a diesel multi cylinder engine with two-stroke is disclosed. A diesel multi cylinder engine with two-stroke comprises a reciprocating piston (120) with a piston ring which slides on the inner surface of a cylinder liner (111) in each cylinder (110). The cylinder lubricating device (1) spreads lubricants on the surface of the cylinder liner (111) at an accurate amount through a plurality of injection parts (112) arranged at the same height around the cylinder (110) based on a reciprocating motion of the piston (120). The cylinder lubricating device (1) comprises a plurality of piston pumps with injection plungers (30) which slide from a start position (S) to a finish position (E) in an injection cylinder (20); a common drive (31) with linear actuators (41, 46) for driving the injection plungers (30) at the same time; and the injection plunger (30) which has an overall stroke from the start position (S) to the finish position (E). The diameter of the injection cylinder is formed to provide the lubricants at the accurate amount as the injection plunger (30) moves from the start position to the finish position through partial strokes of various time slots.</p> |
