Abstract
An engine block assembly utilized within a liquid-cooled engine includes an anti-cavitation engine block having a first cylinder, a second cylinder, and an inter-cylinder wall section located between the first and second cylinders. An anti-cavitation passage is formed through the inter-cylinder wall section that extends between the first cylinder and the second cylinder. A cylinder liner is inserted into the first cylinder and has an outer circumferential surface toward which the anti-cavitation passage opens. A water jacket extends at least partially around the outer circumferential surface of the cylinder liner. 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 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.
