ABSTRACT:
An aluminum alloy cylinder block for use in a water-cooled internal combustion engine has a cylinder with a bore into which a piston is to be movably fitted. A water jacket provided on the outer side wall of the cylinder is adapted to allow the passage of water therein for cooling the engine. The depth of the water jacket from the top of the cylinder block is preferably from 0.2 to 0.5 times the length of the cylinder. A crank case has a side wall connected to the bottom of the water jacket, and a cylinder rib extends from the inside of the side wall of the crank case toward the water jacket.
