摘要： The present system aims to detect, in an initial phase, the scuffing resultant from the contact between the piston and the liner in reciprocating medium and large engines, of two and four strokes. The system operates based on the roughness of the piston's surface (2), as a function of the piston's stroke (1) through the distance sensors radially distributed (3), calculating the medium roughness and comparing it with the standard reference medium roughness. When the deviations found in the roughness increase above a predetermined value, the system produces an audible warning signal, indicating which cylinder is affected, therefore avoiding the failure of the liner and the piston. The system also assesses the state of the contact surfaces of the piston rings and their lubrication, as well as the piston's deflection. Using the acquired data it is possible to vary the operating parameters of the engines, such parameters being lubrication or load rate.
