Problems solved by technology

Therefore, the working space or scavenging space where the distribution system is located, and engine operating conditions such as cylinder liner wall temperature, engine load, efficiency of the cylinder liner cooling system all contribute to changing the viscosity of the lubricant at the time of injection , thus having a negative impact on the performance of the lubrication system

Embodiment Construction

[0051] figure 1 A schematic diagram of a cylinder 3 of a large engine is shown, comprising a cylinder head hereinafter denoted with reference number 1 . The cylinder head 1 is particularly suitable for large diesel engines which are mainly designed as two-stroke diesel internal combustion engines with direct-flow scavenging. The basic components of a large engine generally having a plurality of cylinders 3 are known per se.

[0052] The cylinder head 1 comprises a top region 5 and a side region 6 which delimit a combustion chamber 7 of a cylinder 3 in the mounted state, as figure 1 shown. In this regard, in the mounted state the top region 5 of the cylinder head 1 forms a boundary surface of the combustion chamber 7 which is arranged opposite the piston end face 41 and perpendicular to the axis A-A of the cylinder head 1, as figure 2 shown. The side region 6 adjoins the top region 5 and, according to the illustration, the upper part of the side region 6 leading into the t...

Abstract

The invention provides a cylinder lubricating device. A lubricant injection device (30, 60, 130) for an internal combustion engine comprising a lubricant distribution element (31, 61, 131) for supplying lubricant to the lubricant distribution element (31, 61, 131) passages (32, 62, 132) and inlets (33, 63, 133) for receiving lubricant from a lubricant supply (34, 64, 134). The lubricant distribution element (31, 61, 131) comprises openings (35, 65, 135) for distributing lubricant onto the surface of the cylinder liner (8) or piston (4), the openings (35, 65, 135) can be closed by closing elements (36, 66, 136) to interrupt the lubricant supply. The lubricant injection device also includes a lubricant heating element (38, 68, 138) for heating the lubricant in the passage (32, 62, 132).

Description

technical field [0001] The invention relates to a cylinder lubricating device for a large engine, especially a large diesel engine. Background technique [0002] Various types of cylinder lubricating devices have been constructed for internal combustion engines used in the automotive field or for large engines. [0003] Particularly in the case of large diesel engines, which can be designed as two-stroke or four-stroke internal combustion engines, large engines are often used as drive units for ships or also for stationary operations, for example for driving large generators for generating electrical energy. In this respect, large engines are usually operated for a considerable period of time, which places high demands on the operational safety and availability of such engines. During particularly long maintenance intervals, low wear and economical handling of running supply items are therefore core criteria. [0004] When the engine is running, the piston slides along the...
