Abstract

The invention relates to a cylinder block (1) for an internal combustion engine, consisting of: an upper part (2) comprising a plurality of cylindrical bores (3) which are aligned along a longitudinal axis and a water sleeve (3) which surrounds the bores; and a lower part (4) such as a skirt, which defines a space for a crankshaft mechanism. The inventive cylinder block (1) comprises two longitudinal faces which are disposed on either side of the line of cylindrical bores (3) and at least one of said faces is equipped with at least one shell assembly, said shell assembly forming chambers which are not connected to one another and comprising an outer common wall which extends continuously along part of the length of one longitudinal face. The invention also relates to an internal combustion engine comprising one such cylinder block, as well as a moulding method for producing such cylinder blocks.
