ABSTRACT:
A cylinder block comprises an upper section having a plurality of engine cylinder bores therein, the upper section having first and second oppositely disposed wall members, and a skirt section having a cavity defining a crankcase for an engine crankshaft, the skirt section having first and second oppositely disposed walls which are integral to and in straight alignment with the first and second wall members of the upper section, respectively, thereby effectively preventing noise radiation from the skirt section and improving the torsional and flexural rigidities of the cylinder block.
