Inter-cylinder bore coolant passage for enhanced cavitation protection in an engine block

An engine block assembly utilized within a liquid-cooled engine, the engine block assembly comprising:

• an anti-cavitation engine block, comprising:
• a first cylinder having a first cylinder centerline;
• a second cylinder having a second cylinder centerline;
• an inter-cylinder wall section located between the first cylinder and the second cylinder, as taken along a longitudinal axis perpendicular to the first cylinder centerline and to the second cylinder centerline;
• and
• an anti-cavitation passage formed through the inter-cylinder wall section that extends between the first cylinder and the second cylinder;
• a cylinder liner inserted into the first cylinder and having an outer circumferential surface toward which the anti-cavitation passage opens;
• and
• a water jacket extending at least partially around the outer circumferential surface of the cylinder liner;
• wherein the anti-cavitation passage is formed through the inter-cylinder wall section at a location adjacent a region of thrust displacement of the cylinder liner, as taken axially along the first cylinder centerline, and enables a flow of liquid coolant in the water jacket therethrough to deter cavitation within the water jacket adjacent the region of thrust displacement of the cylinder liner during operation of the liquid-cooled engine.
