Abstract
An engine piston-pin sliding structure includes a piston pin slidably engaged into a pin boss of an engine piston and having a base and a hard carbon coating formed on the base so as to define a sliding surface slidable over a bearing surface of the pin boss and a lubricant interposed between the sliding surface of the piston pin and the bearing surface of the pin boss. The hard carbon coating contains 25 atomic % or less of hydrogen, and the lubricant contains at least one of an ashless fatty-ester friction modifier and an ashless aliphatic-amine friction modifier.
