Embodiment Construction

[0054] according to figure 1 The illustrated piston-cylinder arrangement 2 of a large engine 1 or compressor comprises a cylinder 20 and a piston 3 . The cylinder block 20 has a cylinder liner 17 delimiting a cylinder interior space 18 . The piston 3 has a piston top 5 and a piston bottom 6 . The piston jacket surface 4 , the piston upper side 5 and the piston underside 6 delimit a piston body 8 . The piston body 8 can comprise several parts, for example it can comprise a piston head 38 and a piston skirt 39 . The piston body 8 can be at least partially provided with a hollow space 40 through which coolant can be introduced into the piston body 8 . The piston 3 comprises a lubricant collecting device 7 arranged in the piston inner space. The lubricant collecting means 7 comprises a recess 11 at the piston jacket surface 4 and a channel 9 for receiving a lubricant-containing gas 10 . The channel 9 adjoins the recess 11 in the piston body 8 , so that a lubricant-containing ...

Abstract

The invention relates to a piston cylinder device (2) for an internal combustion engine and a large-scale engine. The internal combustion engine is particularly a large-scale engine (1) or a compressor. The piston cylinder device includes a cylinder body (20) and a piston (3), wherein the cylinder body (20) is provided with a cylinder sleeve (17) which defines the internal space (18) of the cylinder body, and the piston (3) is provided with a piston sheath surface (4), a piston upper side (5), and a piston lower side (6). The piston (3) includes a lubricant collecting device (7) arranged in the internal space of the piston. The lubricant collecting device (7) includes a recessed part (11) at the piston sheath surface (4) and a channel (9) for receiving the gas (10) containing lubricant agent, wherein the channel (9) is adjacent to the recessed part (11) in the piston body (8) so that the gas (10) containing lubricant agent can pass through the channel (9) to be led into a storing device (13).

Description

technical field [0001] The invention relates to a piston-cylinder arrangement with a lubricant collecting device according to the preamble of claim 1 . The invention also relates to internal combustion engines, in particular large engines having a piston-cylinder arrangement including a lubricant collection arrangement. Background technique [0002] Large engines, in particular in the embodiment of large diesel engines which can be designed as two-stroke or four-stroke internal combustion engines, are often used as marine drive units or can also be used for stationary operations, for example, for driving large generators to generate electrical energy. In this regard, large engines are operated for a considerable period of time in a continuous mode of operation which leads to high demands on operational safety and effectiveness. For this purpose, in particular long intervals between maintenance, low wear and economical handling of operating materials are central criteria fo...
