ABSTRACT:
A hollow valve is used as an inlet or exhaust valve in an internal combustion engine. A hollow valve has a valve head and a valve stem. A cavity extends from the valve head to the valve stem. A low melting point alloy in solid is inserted into the cavity and occupies 1/4 to 1/3 of the cavity in volume. During operation of the engine, the alloy is melted, thereby cooling the valve.
