Abstract
A cylinder block for a water-cooled internal combustion engine has a top deck, a cylinder wall structure defining a row of cylinder bores, and a water jacket wall structure defining a water jacket around the cylinder bores. The jacket wall structure has a plurality of cylinder head bolt bosses each formed with a bolt hole for a cylinder head bolt for fastening a cylinder head on the top deck of the cylinder block. At least one of the head bolt bosses is a terminal head bolt boss which is formed at an end portion of the cylinder block, and which is connected, by a rib, with the cylinder wall structure and the top deck to prevent stress concentration and cracks.
