Embodiment Construction

[0018] The invention will now be described in more detail with reference to the accompanying drawings.

[0019] exist figure 1 In , a part of an engine block 1 of an internal combustion engine is shown. Although only one cylinder is shown, the engine can include any reasonable number of cylinders, for example arranged in an inline configuration or in a V configuration. The engine is a large four-stroke internal combustion engine, such as an engine used in a power plant or a main or auxiliary engine of a ship. The invention is applicable to both compression ignition engines and spark ignition engines.

[0020] The cylinder liner 2 is arranged in the engine block 1 . The main part of the cylinder liner 2 is located inside the engine block 1 , but a part of the cylinder liner 2 extends above the engine block 1 and protrudes outwards so that it can be supported against the top surface of the engine block 1 . The engine block 1 comprises a first support surface 8a parallel to t...

Abstract

An engine block arrangement in a reciprocating piston internal combustion engine, the arrangement comprising an engine block (1), a cylinder liner (2) being arranged inside the engine block (1), a lubricating oil chamber (6) being arranged between the cylinder liner (2) and the engine block (1), and means (3, 4) for introducing lubricating oil into the lubricating oil chamber (6). The invention also concerns a method for preventing fretting.

Description

technical field [0001] The invention relates to an engine block arrangement in a reciprocating piston internal combustion engine, the arrangement comprising an engine block and a cylinder liner arranged in the engine block, as defined in the preamble of claim 1 . The invention also relates to a method according to the preamble of claim 8 for preventing abrasion of the contact surfaces between a cylinder liner and an engine block. Background technique [0002] Abrasion refers to wear caused when two surfaces move relative to each other by very small amplitudes. A common cause of abrasion is vibration under load. Erosion is a common problem in internal combustion engines in which the contact surfaces between the cylinder liner and the engine block move relative to each other. These small movements are mainly caused by the movement of the piston and the pressure change in the cylinder. [0003] In Japanese patent application JP59200043A the problem of abrasion of cylinder li...
