Abstract
An anti-cavitation engine block includes a first cylinder having a first cylinder centerline, a second cylinder having a second cylinder centerline, and a first inter-cylinder wall section located between the first cylinder and the second cylinder along an axis perpendicular to the first and second cylinder centerlines. A first plurality of anti-cavitation channels is formed in the first inter-cylinder wall section. A cylinder liner is inserted into the first cylinder and has an outer circumferential surface toward which the first plurality of anti-cavitation channels open. A water jacket extends at least partially around the outer circumferential surface of the cylinder liner. The first plurality of anti-cavitation channels increase local radial thicknesses of the water jacket to deter cavitation within the water jacket and adjacent the cylinder liner during engine operation.
