Claims26
A cylinder block for an engine, having a cylinder;
- and a separately made liner for said cylinder, the material of said liner being composed at least in part of a hypoeutectic aluminum-containing material having silicon carbide particles dispersed therein;
- wherein said block is composed at least in part of a hypoeutectic aluminum-containing substance.
A method of making a cylinder block for an engine, comprising the steps of:
- providing a cylinder block having a cylinder and composed at least in part of a hypoeutectic aluminum containing substance;
- providing a hypoeutectic aluminum-containing material having silicon carbide particles dispersed therein;
- and
- processing said material to form a liner for said cylinder, the processing step including casting said liner from said material.
