Embodiment Construction
[0057] The specific details of the engine, the cylinder lubricating device and the method for controlling the injection of lubricating fluid injected into the cylinders of the engine according to the present invention will be described below through exemplary embodiments.
[0058] The present invention relates to an engine cylinder lubricating device 1, which is used for a crosshead large-scale two-stroke diesel engine 100, and the engine can constitute a main propulsion system of a ship or a fixed power generating engine. refer to Image 6 with 7 , the engine 100 has a plurality of cylinders 100 (a part of one cylinder is in Image 6 shown in ), typically three to fourteen cylinders 110 arranged in a line, but other arrangements or numbers of cylinders 110 are possible. Each cylinder 110 is provided with a cylinder liner 111 forming an inner surface of the cylinder 110 . In a large two-stroke engine 100, the cylinder bore (bore) is typically between 250mm and 1200mm. The ...

A cylinder lubricating device for a large two-stroke diesel multi-cylinder engine operating at low speed, in which a reciprocating piston having a piston ring sliding on the inner surface of the cylinder liner is arranged in each cylinder of the engine, whereby the cylinder lubricating device targets the piston Each reciprocation of the cylinder provides accurately metered cylinder lubricating oil to the inner surface of the cylinder liner through multiple injection points, and the injection points are distributed at equal heights around the cylinder circumference; the cylinder lubrication device includes multiple piston pumps with metering plungers, and a common drive comprising a linear actuator for simultaneously driving all dosing plungers having a predetermined full stroke between a start position (S) and an end position (E) in which the dosing cylinder The diameter is set to deliver a precise dose by moving the dosing plunger within a small fraction of the maximum stroke, so that the dosing plunger can move from the start position in part of the stroke before the dosing plunger needs to return to the start position Multiple moves in the direction of the end position.
Description
technical field [0001] The present invention relates to a cylinder lubrication arrangement for a large, low-speed operating two-stroke diesel engine, and to a method of operating a cylinder lubrication system. [0002] More preferably, the present invention relates to a cylinder lubrication device for a large low-speed running two-stroke diesel engine having a plurality of piston pumps driven simultaneously by a common drive. [0003] The present invention also relates to a hydraulically activated cylinder lubricator and a method of operating control for dosing cylinder oil as specified by the engine designer and as a function of engine operating conditions, load and user demand. Background technique [0004] In the field of large two-stroke diesel engines with crossheads, such as are used in power plants or as prime movers for marine vessels, the cylinders and pistons of the engines require particularly precise and extensive lubrication. Typically, such engines run on the ...
