Abstract
A combustion engine is provided that includes an engine block with a fiber material in a resin. The engine block defines a piston bore and a bore liner positioned within the piston bore and includes a substrate and a coating positioned on an interior surface of the substrate. An exterior surface of the substrate defines a retention feature.
Claims20
A combustion engine, comprising:
- an engine block comprising a fiber material in a resin, the engine block defining a wall between adjacent piston bores;
- one or more reinforcement inserts positioned within the wall between adjacent piston bores, wherein the one or more reinforcement inserts are coated with the fiber material and the resin such that the one or more reinforcement inserts are substantially surrounded by the fiber material and the resin;
- and
- a bore liner positioned within each piston bore, wherein each of the bore liners comprises a substrate having an interior surface on which a coating is positioned and an exterior surface defining a retention feature that extends into the wall between adjacent piston bores.

A combustion engine, comprising:
- an engine block substantially comprising a fiber material within a resin, the engine block defining a deck face, a plurality of piston bores, one or more walls between the piston bores, and a bulk head;
- and
- a plurality of reinforcement inserts positioned in the one or more walls between the piston bores, wherein the inserts are substantially surrounded by the fiber material in the resin.
A method of forming a combustion engine, comprising:
- providing a mold for forming an engine block;
- positioning a plurality of bore liners that each define a retention feature within the mold;
- positioning one or more reinforcement inserts within the mold between adjacent bore liners;
- injecting a fiber material and a resin into the mold, wherein the fiber material and the resin substantially surround the reinforcement inserts;
- and
- solidifying the resin to form the engine block.
