Torn and folded metal (TFM) on honed cylinder bore surfaces has been observed and studied for decades. However, there is no objective and quantitative method for ranking the severity of TFM. Studies on its effect on the scuffing resistance of a cylinder bore and piston skirt/piston ring are ...
The surface used for calculation of the correction factors and contact stiffness curve is a typical HDDE plateau honed cylinder liner surface. The time dependent homogenized Reynolds equation in 1D with the correction factors implemented can be written as [22]:(1)∂∂x(a11ρ12η∂p∂x)...
should be performed centered in this region. Here, and according to the right-hand panel ofFigure 5andFigure 7, the best conditions to run-in the engine used in this study would be at medium to high engine speeds, without much influence from varying the cylinder pressure, as the generation...
