Abstract
A cylinder block includes a cylinder block body and a load path structure. The cylinder block body defines a first cylinder block upper bore. The load path structure includes a first support rib having a first support rib body interfacing with the first cylinder block upper bore. The load path structure is configured to transfer a load from the first cylinder block upper bore along a non-linear path within the cylinder block body away from the first cylinder block upper bore.

A cylinder block comprising:
- a cylinder block body defining a first cylinder block upper bore;
- a first lower portion of a first cylinder;
- a second lower portion of a second cylinder;
- and
- a load path structure comprising a first support rib having a first support rib body interfacing with the first cylinder block upper bore and a beam extending outward from the first support rib body and having a first end positioned adjacent an end surface of the cylinder block and a second end, opposite the first end, located away from the first end, the load path structure being configured to transfer a load from the first cylinder block upper bore along a non-linear path within the cylinder block body away from the first cylinder block upper bore, the first support rib aligned with a vertical axis that extends between the first lower portion of the first cylinder and the second lower portion of the second cylinder.
A cylinder block comprising:
- a cylinder block body defining a first cylinder block upper bore and a second cylinder block upper bore;
- a first lower portion of a first cylinder;
- a second lower portion of a second cylinder;
- a load path structure comprising:
- a first support rib having a first support rib body interfacing with the first cylinder block upper bore and a first beam extending outward from the first support rib body and having a first beam first end positioned adjacent an end surface of the cylinder block body and a first beam second end, opposite the first end, located away from the first end, the first support rib extending away from the cylinder block body in a direction that is parallel to the first cylinder block upper bore, the first support rib aligned with a vertical axis that extends between the first lower portion of the first cylinder and the second lower portion of the second cylinder, and
- a second support rib having a second support rib body interfacing with the second cylinder block upper bore and a second beam extending outward from the second support rib body and having a second beam first end positioned adjacent the end surface of the cylinder block body and a second beam second end, opposite the first end, located away from the first end, the second support rib extending away from the cylinder block body in a direction that is parallel to the second cylinder block upper bore;
- and
- a cylinder skirt portion extending between the first support rib body and the second support rib body, the cylinder skirt portion being recessed relative to the first support rib and the second support rib.
