Embodiment Construction

[0046] figure 1 A schematic representation of an embodiment of a lubricating device according to the invention in combination with a large diesel engine is shown. The lubricating device is indicated generally with reference numeral 1 , while the large diesel engine is generally indicated with reference numeral 10 .

[0047] In the following description, reference is made by way of example to an embodiment in which the large diesel engine 10 is designed as a large two-stroke diesel engine 10 with longitudinal scavenging. Since these large diesel engines 10 are known in the art, a detailed description is not required. Furthermore, reference is made by way of example to the application of the large diesel engine 10 as the main propulsion unit of a ship or watercraft.

[0048] Of course, the present invention is not limited to this particular type of large diesel engine 10 . In particular, the large diesel engine 10 may be any type of large diesel engine, as these are used eg a...

Abstract

The invention proposes a lubrication arrangement for a large diesel engine, in particular to the lubrication arrangement for the lubrication of cylinders (11) of a large diesel engine (10), comprisinga reservoir (2) for a lubricant, a lubrication device (3) for being mounted to the large diesel engine (10), and a supply line (4) connecting the reservoir (2) with an inlet (31) of the lubrication device (3) for delivering the lubricant from the reservoir (2) to the lubrication device (3), wherein the lubrication device (3) comprises a plurality of injection pumps (32) for delivering the lubricant into the cylinders (11), and wherein a feed pump (5) is provided, which is arranged to pressurize the lubricant in the supply line (4), so that the lubricant is supplied with an overpressure to theinlet (31) of the lubrication device (3). In addition, a combination of a lubrication arrangement and a large diesel engine is proposed.

Description

technical field [0001] The invention relates to a lubricating device for cylinder lubrication of a large diesel engine and the combination of the lubricating device and the large diesel engine. Background technique [0002] Large diesel engines, which can be designed as two-stroke or four-stroke engines (e.g. as large two-stroke diesel engines with longitudinal scavenging), are often used as main propulsion units for ships, or also in stationary operation, e.g. Used to drive large generators to generate electricity. Here, the engine is usually operated constantly over a considerable period of time, which places high demands on operational reliability and availability. For this reason, long predictable intervals between maintenance, low wear and economical use of fuel and operating materials are core criteria for engine operation for operators. [0003] Especially in view of the increasing demands on environmental protection, the operation of large diesel engines is becomin...
