Embodiment Construction

[0028] figure 1 and 2 The construction and installation position of the structure of the known cylinder liner 2 are shown. for this in figure 1 Part of it depicts the cylinder housing 1 , also referred to as the cylinder housing, of the internal combustion engine, which is not shown further. A wet cylinder liner 2 , in which a reciprocating piston 3 is guided on a running surface 4 , is inserted into the cylinder housing 1 , through which the coolant directly circulates. The cylinder liner 2 is fitted into the receptacle 7 or the guide 8 of the cylinder housing 1 with the flange 5 and axially offset therefrom on the outer side 6 . In order to effectively seal off the coolant space 9 , sealing rings 10 , 11 are arranged offset from the flange 5 and in the region of the guide 8 . figure 2 Shows two cylinder liners 2 arranged in the cylinder housing 1 in the direction of the longitudinal axis 13 of the cylinder housing 1 , the center distance S of the two cylinder liners M ...

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...
