Abstract
The tendencies of cylinder surface topography changes during “zero-wear” process are mentioned. It is proved that the assessment of amplitude parameter of worn cylinder surface is sufficient to monitor the shape of the amplitude distribution (material ratio curve). The information that the standard deviation height of fine part resulted from wear process is proportional to maximum height of worn surface is very important. It is possible to obtain simulated worn surface profiles when the horizontal parameters of their fine parts are known. The presented above technique can be extended into worn cylinder surfaces measured in three dimensions. The last part of paper is devoted to prediction of the local cylinder linear wear, determined as change of amplitude parameter. This procedure is based on the linear dependence between volumetric wear and initial material volume of the cylinder surface topography. The new models were successfully used for a large number of cylinder liners after ‘zero-wear’ process in internal combustion engines.
