Cylinder Liner Honed Surface Optimisation - a Manufacture-Characterisation-Function Study
Paper i proceeding, 2007

In order to comply with increasingly stringent emission standards, engine manufacturers strive to reduce the oil consumption and frictional losses. One of the major contributors to it is the cylinder liner surface. Therefore, it is important to investigate what are the optimal machining parameters to manufacture liner topography with an optimal function. Numerous liners were slide honed, varying the base honing pressure and plateau honing time. The samples of the liners were measured on stylus and interferometer, and characterized by 2D and 3D parameters. The interference measurements were inputted in a flow simulation program and the mean oil flow and hydrodynamic shear stress were calculated for different nominal separations between the ring and liner. The analytical results show that a relatively low base honing pressure and longer plateau honing time give a surface with the lowest mean oil flow and the highest shear stress. A good correlation among the oil flow, shear stress, base honing pressure, Sa, Sk, Svk, and other roughness parameters was also found.
