FIBER REINFORCED CERAMIC MATRIX COMPOSITE PISTON AND CYLINDER/SLEEVE FOR AN INTERNAL COMBUSTION ENGINE |
摘要 |
<p>This invention discloses a "ceramic" piston and cylinder/sleeve pair for an internal combustion engine. The pair has low coefficients of thermal expansion for closer parts tolerances without danger of seizing and/or breakage/cracking from dissimilar part expansions. A piston is formed of a structural fiber reinforced ceramic matrix composite material and then a combined first erosion-resistant and self-lubricating material is applied to a surface of a skirt portion of the piston. A cylinder/sleeve is formed of a structural fiber reinforced ceramic matrix composite material and then a second combined erosion-resistant and self-lubricating material is applied to the surface of the cylinder/sleeve.</p> |
