<p>A block casting (10) for an internal combustion engine and method of its manufacture provide reduced engine block size and weight, and/or increased engine displacement, through cylinder-forming walls (11, 21) that decrease in thickness from minimal explosion-resistant thicknesses (11a, 21a) at the combustion chamber ends (12a) of the cylinders to reduced thicknesses (11b, 21b) at their other ends.</p> |
