Cylinder liner wear measurement
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 … WebThe KONGSBERG cylinder liner monitoring system monitors the piston running performance by measuring the temperature of the upper part of the cylinder liners. Increased friction between the piston rings and the cylinder liner creates an elevated temperature level leading to abnormal liner wear and potential piston ring breakage. …
