The lubrication problems of wear, friction, oil consumption and scuffing in internal combustion engines are closely related with the oil-film thickness between piston rings and cylinder liners. The piston rings usually operate under the condition of starved lubrication for the pack slide. We analyze on the oil-film characteristics of a piston ring pack, taking account of the interaction between rings. The experiments to examine the oil-film behaviour of ring specimens sliding under oil starvation are conducted using reciprocating test equipment. The oil-film characteristics of starved lubrication are clarified from the results of calculations and experiments.
