Cylinder liner wear measurement
WebSep 15, 2024 · The estimation of cylinder liner wear by collecting radioactive wear debris from retrieved lubricant does not reflect the wear information at different locations [7], [8]. Therefore, a more precise method of cylinder liner wear measurement during running-in is to evaluate the surface topography changes [9], [10]. Gara et al. measured the ... WebSeveral approaches have been developed to measure instantaneous friction between the piston assembly and cylinder in internal combustion (IC) engines, such as floating-liner, reciprocating liner, instantaneous mean effective pressure (IMEP), fixed sleeve, and (P-ω) method and tribological bench tests. However, the “floating-liner method” and the …
