Appeal No. 96-3202 Application No. 08/183,464 APPENDIX 1. A low friction valve train actuating at least one valve in an internal combustion engine comprising: a cam shaft having at least one cam; and a tappet contacting said at least one cam and valve, said at least one cam and tappet having outer surfaces with an open porosity; and a solid film lubricant impregnated and anchored in said open porosity, said solid film lubricant being stable to temperatures at about 700°F to retain a low coefficient of friction and promote rapid formation of a stable oil film to reduce friction therebetween in an oil starved environment. 14. A low friction valve train actuating at least one valve in an internal combustion engine comprising: a cam shaft having at least one cam with a base portion and lobe portion, said base and lobe portions having outer surfaces treated such that the treated surfaces have an open porosity; a tappet having an outer surface treated such that the treated surface has an open porosity, said tappet further including a wear resistant insert secured to said tappet and contacting said at least one cam; and a solid film lubricant impregnated and anchored in said open porosity of said treated surfaces of said base portion and said lobe portion and said tappet, said solid film 1Page: Previous 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 NextLast modified: November 3, 2007
