Abstract: The present application relates to rib structure on cylinder block. A cylinder block having a top surface, an inner bottom surface, a cylinder opening on the top surface, and a head boss positioned on the top surface, centered on a first axis, and configured to engage with a fastener at an initial position, which defines a first depth. The cylinder block includes a first main boss positioned on the inner bottom surface, centered on a second axis, and configured to engage with a first main fastener at a first end position, which defines a second depth. The cylinder block includes a second main boss positioned on the inner bottom surface and configured to engage with a second main fastener at a second end position, which defines a third depth. The cylinder block includes a first rib path extending from the first depth to the second depth and a second rib path extending from the first depth to the third depth.
