Engine with carbon deposit resistant component

摘要

Carbon deposits on engine components can negatively affect engine performance. An engine of the present disclosure includes at least one carbon deposit resistant engine component attached to an engine housing. The engine component includes at least one relatively high surface tension surface that is a non-contact wear surface and to which a relatively low surface tension coating is attached. The relatively low surface tension coating has a surface tension at least one of equal to and less than 30 dyne/cm.
