ABSTRACT:
The present invention relates to improvements in internal combustion engines by the utilization of sintered silicon carbide for the fabrication of certain engine components wherein the silicon carbide starting material used to produce the sintered components is in an ultra-fine form. The engine components comprise the valve train and the power assembly. The valve train is comprised of the valve guides, valves, valve caps, rocker arms, valve spring retainer rings, push rods and tappets (lifters). The power assembly is comprised of cylinder lines, valve seats, exhaust port liners, exhaust manifold, flames plates, pistons, piston rings, piston pins and connecting rods.
