Problems solved by technology

Such injections run the risk of the scavenging being able to carry away part of the lubricating oil, thus risking insufficient lubrication, or alternatively, the risk of requiring a greater consumption of lubricating oil

Embodiment Construction

[0032] according to figure 1 The illustrated system of the invention is shown as an arrangement with three injection units / valves, however, the number is not limited to three. The injection unit consists of a dosing unit mounted directly on each individual valve. Each cylinder of the engine has a corresponding system connected to it.

[0033] Dosing unit (which is in figure 2shown more clearly in ) consists of piston 1, which may have a differential piston as shown. When the system is depressurized, the piston is held to the left by the spring 1'. When valve 3 is opened, pressurized oil is supplied from a pump (not shown) to compartment 5 via pressurized pipe 17, thereby causing the piston to move to the right, the oil moved by the right end of the piston passes through pressure valve 7 via The conveying pipes 9 , 24 and 28 lead to the compartment 30 before reaching the nozzle needle 18 and further lead through the nozzle pipe 12 of the nozzle 11 . The function of the va...

Abstract

There is described a dosing system for cylinder lubrication oil for large diesel motors, e.g. in marine engines. The system has a supply pipe and a return pipe provided with each their valve (3, 27), and which are connected with a central supply pump. This comprises a number of injection units that are connected with the said pipes. Each unit comprises a number of injection nozzles for injecting at least one compact lubricating oil jet on the cylinder surface in an associated cylinder, as atomisation of the lubricating oil jet through the injection nozzle is avoided to the greatest possible extent, a piston (1) provided at a rearmost part of the nozzle rod, and a controllable motor (37) which via a screw (33) is connected with the piston (1) in order thereby to adjust the pump stroke / position of the piston (1). Furthermore, the system comprises a cental computer for controlling the valves (3, 27) and the motor (37) so that precise control of the amount of oil and precise timing are achieved.

Description

[0001] This divisional application is a divisional application based on the Chinese patent application with application number 200580024579.4 (its international application number is PCT / DK2005 / 000386), the application date is June 14, 2005, and the invention title is "Controllable Supply System" . technical field [0002] The present invention relates to a method of operating a dosing system for cylinder lubricating oil of a large diesel engine, such as a marine engine, having a supply pipe and a return pipe each with a valve and connected to a central feed pump, and having A number of injection units corresponding to the number of lubrication points in each cylinder and connected to said pipe, each unit comprising: [0003] - Injection nozzles for each lubrication point for injecting lubricating oil into the associated cylinders, said injection nozzles comprising a valve needle and a compartment in front of said valve needle, which abuts at the rear on on the compression sp...
