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.

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.

Selective engine block channeling for enhanced cavitation protection

A thermal displacement compensation assembly for an engine system including a cylinder head and an exhaust manifold coupled to the cylinder head. The thermal displacement assembly includes a bracket configured to be operatively coupled to cylinder head and to the exhaust manifold and a multi-layer coupler. The multi-layer coupler is configured to be disposed between the bracket and the cylinder head, wherein a first component of the coupler is configured to slide with respect to a second component of the coupler such that relative movement between the bracket and one of the cylinder head and exhaust manifold is enabled by relative movement of the first component with the second component of the multi-layer coupler.
