Abstract

A process for casting a cylinder block blank made of light alloy provided with a cylinder barrel reinforced around its cylinder bore with a reinforcing tubular body and a crankcase provided continuous to the cylinder bore, which includes placing the reinforcing tubular body in a first cavity formed for shaping a cylinder barrel at the lower portion of a mold which is formed at its upper portion with a second cavity for shaping a crankcase communicating with the first cavity, and pouring a light alloy molten metal from the lower portion of the first cavity into the first and second cavities while simultaneously venting gas from the first and second cavities.
