Abstract:
1. A method of in-situ forming a low friction coating on a cylinder wall of an internal combustion engine, said method comprising: providing a lubricant to a region within said engine defined by said cylinder wall; introducing a solid lubricant additive comprising at least one of molybdenum disulfide and tungsten disulfide to said region; and traversing a piston along a reciprocating path defined by said cylinder wall such that movement of said piston is substantially limited along a reciprocating direction within a region defined by said cylinder wall such that a tribochemical interaction between a portion of said solid lubricant additive that is carried by said lubricant and situated between said cylinder wall and said piston forms a protective layer on said cylinder wall.
