ABSTRACT:
A closed-deck cylinder block of a light alloy such as an aluminum alloy for use in a water-cooled internal combustion engine includes a cylinder-defining portion having a plurality of cylinder bores defined therein, and a crankcase-defining portion integral with the cylinder-defining portion. The cylinder-defining portion includes a water jacket extending substantially the entire length of each of the cylinder bores and defined by an inner side wall, and outer side wall spaced therefrom, and a bottom wall interconnecting the inner and outer side walls. The bottom wall has a wall thickness substantially equal to at least one of the wall thicknesses of the inner and outer side walls. The wall thicknesses of the inner and outer side walls are substantially equal to each other.
