Example Embodiment

[0028] figure 1 with 2 The structure and installation position of the structure of the known cylinder liner 2 are shown. For this reason figure 1 A part of it depicts a cylinder housing 1 of an internal combustion engine that is not shown further, also called a cylinder housing. A wet cylinder liner 2 directly circulated by the coolant is installed in the cylinder housing 1, and a piston 3 reciprocating in the cylinder liner is guided on a working surface 4. The cylinder liner 2 is fitted into the receiving portion 7 or the guide portion 8 of the cylinder housing 1 by means of a flange 5 and an axially offset from this on the outer side 6. In order to effectively seal the coolant space 9, sealing rings 10, 11 are arranged offset from the flange 5 and in the area of ​​the guide 8. figure 2 Two cylinder liners 2 arranged in the direction of the longitudinal axis 13 of the cylinder housing 1 in the cylinder housing 1 are shown. The center distance of the two cylinder liners is S ...

Abstract

The invention relates to a cylinder liner (2) of a cylinder of an internal combustion engine, in which cylinder liner an oscillating piston (3) is guided on a running surface (4), wherein the cylinder liner (2) is fixed vertically by means of a collar (5) between a cylinder housing (1) and a cylinder head. The wet cylinder liner (2) comprises an outer side (6) which deviates from a circular shape and/or a rotationally asymmetrical outer contour of the collar (5). The cylinder liner (2) is fitted in a positionally oriented manner in a corresponding receptacle of the cylinder housing (1).

Description

technical field [0001] The invention relates to a cylinder liner for a cylinder of an internal combustion engine according to the features of the respective preambles of claims 1 and 2 . Background technique [0002] The cylinder liner has the task of minimizing wear as a friction partner of the piston rings, dissipating the heat of combustion and improving the mechanical stability of the system during operation while minimizing deformations caused by operation. According to the function, it can be divided into wet type and dry type cylinder liner. [0003] The wet cylinder liner has a flange by means of which the bushing is fixed vertically in the engine block or cylinder housing. The rotationally symmetrical outer contour of the cylinder liner including the flange determines the minimum cylinder spacing. The wet bushing is pushed into the cylinder housing into a correspondingly formed receptacle for this purpose. Sealing rings are used for coolant and oil sealing. To d...
