Method and system for cylinder liner

Systems and methods for forming a plurality of valleys (201) on an inner circumferential surface (121) of a cylinder liner (107) to achieve a uniform oil film thickness are disclosed. In one aspect, an internal combustion engine (101) includes: a piston (113); and a cylinder liner (107) surrounding...

Zusammenfassung:	Systems and methods for forming a plurality of valleys (201) on an inner circumferential surface (121) of a cylinder liner (107) to achieve a uniform oil film thickness are disclosed. In one aspect, an internal combustion engine (101) includes: a piston (113); and a cylinder liner (107) surrounding the piston (113), in which the cylinder liner (107) has a plurality of valleys (201) on an inner circumferential surface (121) of the cylinder liner (107), and in which the plurality of valleys (201) are formed at a frequency of 7 to 14 valleys per millimeter (mm), having a depth of at least 1 micron ([mu] m). 公开了用于在气缸套(107)的内圆周表面(121)上形成多个谷(201)以获得均匀油膜厚度的系统和方法。在一个方面，一种内燃发动机(101)包括：活塞(113)；以及包围活塞(113)的气缸套(107)，其中，气缸套(107)具有在气缸套(107)的内圆周表面(121)上的多个谷(201)，并且其中，多个谷(201)形成为每毫米(mm)7至14个谷的频率，具有至少1微米(μm)的深度。
