Abstract (en)

[origin: WO2011116768A1] There is described a dosing system for cylinder lubrication oil for large diesel engine cylinders (5), e.g. in marine engines (32), and including: a central lubricating oil supply, e.g. a central pump station (1);a supply line (31) and a return line (33) to/from the lubricating oil supply for circulating the lubricating oil;a number of injectors (6) corresponding to the number of cylinders in the engine or a multiple thereof, and which are adapted to inject cylinder lubricating oil into an associated cylinder via a nozzle aperture (20), and which via branch lines (7, 15, 16) are connected with the supply and return lines;opening/closing valve units (3) provided in the branch lines (15, 16) between the injectors (6) and the supply and return lines; and a control unit(25) controlling each opening/closing valve unit (3). In order to achieve a flexible central control of injected amount of oil and precise control of timing, the system is designed such that the opening/closing valve units (3) have a first inlet (P) and a first outlet (R) which may connect a first chamber (22) behind a spring-biased closing member (18) in the injectors with the supply line (31) and the return line (33), respectively. The injector (6) further has a second chamber (24) in front of the closing member (18) of the injector, where the second chamber is connected with a branch line (7) connecting the second chamber (24) of the injector with the supply line (31).The control unit (25) is at least connected with the opening/closing valve units (3).
