LIGHT ALLOY PISTON

摘要

In a light alloy piston for use in diesel engines for an indirect fuel injection, a body of fibrous material is embedded in the cast piston head and is formed with a shallow combustion recess. In order to improve the conduction of heat outside the portion formed with the combustion recess, the body of fibrous material has a larger height on the side that is formed with the combustion recess than in the remaining portion of the piston head.
