Abstract The running-in of cylinder liner-piston rings (CLPRs) is the most important process that must be performed before a marine diesel engine can operated. quality directly affects reliability CLPR. surface texture CLPR has been proven to significantly affect its lubrication performance. In this study, tribological behavior during investigated. Three types textures are generated on via lase...

A novel scuffing methodology was developed utilising variable specimen geometry to replicate numerically modelled top compression ring contact pressures (4–62 MPa) from a 12.8-litre heavy duty diesel engine as function of stroke position. Scuffing grade 250 cast iron induced by reciprocating sliding (TE77) against drip lubricated (PAO4) 52100 rectangular operating at 15 Hz and 311 N normal load...

A new engine block with optical access has been designed and manufactured capable of running up to 3000 r/min the same specification as unmodified engine. The window allowed full length liner over a width 25 mm investigate lubricant flow cavitation at contact point between rings cylinder-liner. In addition, it good into combustion chamber allow charged flow, spray visualisation measurements usi...
