Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lubricating oil pump, a lubricating oil pump, a cylinder lubrication system, and an internal combustion engine,

The present invention relates to a cylinder lubrication pump for dosing cylinder lubricating oil into a lubricating quill-opening of a cylinder of an internal combustion engine, particularly a slow-running two-stroke large diesel engine, as well as a cylinder lubrication arrangement And in particular to an internal combustion engine according to the preamble of each independent claim.

Large diesel engines are often used as power units for ships and the like, for example in static operation to drive large generators for generating power. Here, in general, the engine is constantly operating over a significant period of time, which has high demands on operational reliability and availability. For this reason, with respect to the driver, the long intervals between services, low grade wear and, in particular, the economical use of driving materials and fuel is an important standard for machine operation. Among other things, the behavior of the pistons of slow-moving diesel engines of these large bores is also a direct determinant of operating costs and therefore economic viability, through the length of service intervals, availability and consumption of lubricants. Therefore, complex problems associated with lubrication of large diesel engines are increasing in importance.

In large diesel engines, but also in such engines, piston lubrication is carried out by a reciprocating piston or cylinder wall lubrication device, whereby the lubricant minimizes friction between the piston and the running surface and therefore wears the running surface and the piston ring And is applied to the running surface of the cylinder wall for minimization. Thus, for modern engines, such as the RTA engine of Waertsilae, for example, the operating surface wear is less than 0.05 mm per 1,000 hours of operating time. The amount of lubricant delivered should be less than about 1.3 g / kWh, especially for cost reasons, and wear should be minimized at the same time.

An entirely different solution is known for the lubrication system for lubrication of the running surface as well as for the actual operation of the lubrication apparatus itself and also for the lubrication method. A lubricating device is therefore known in which a lubricating oil is applied to a running piston passing through a lubricant opening through a plurality of lubricant openings received in the circumferential direction of the cylinder wall and the lubricant is also distributed axially as well as axially by the piston ring have.

In addition to the manner in which the lubricant is applied to the running surface of the cylinder wall, the dosing of the lubricant is an important point. A wide variety of different oil injection pumps are known in the art for this purpose. Lubricating Cylinders of the Internal Combustion Engine To ensure an even oil distribution of the Qilo, known oil injection pumps include a working piston which drives a specific number of input plungers connected to or attached to the operating pistons. A closing plunger is configured to be drivable in the dosing space so as to reciprocate in the delivery and return strokes over the working movement along the plunger axis. In the return stroke, a preset amount of lubricant is filled into the input space of the top portion of the plunger. Upon receipt of the injection signal, the working piston starts to move and the lubricating oil is pressurized by the plunger driven by the operating piston and the lubricating oil is supplied to each lubricating quill from each input space.

These known cylinder oil injection pumps are described in the examples as CH 673 506, DE 197 43 955 B4, or EP 1 386 063 A1, all of which are very complicated in structure and cause a relatively high price of the pump.

A two-stroke marine diesel engine requires pulsed lubricant flow that is accurately timed, metered, and transported separately to various points around the periphery of each engine cylinder. Since each engine cylinder requires its own pump, such a pump must be made as simple and reliable as possible and at the lowest possible price. In order to meet this need, other pump proposals use only a single piston to carry multiple streams, but in this case it is not possible to guarantee a separate flow to each injection site of the engine cylinder.

It is an object of the present invention to propose an improved cylinder oil injection pump for injecting a cylinder lubricating oil which is thus simple in construction of the oil injection pump and more reliable as a pump known from the state of the art, resulting in considerable cost savings. It is also an object of the present invention to provide an improved internal combustion engine having such a cylinder lubrication arrangement as well as an improved cylinder lubrication arrangement comprising an improved cylinder oil dispensing pump.
