Two-piece compression piston ring of an internal combustion engine
A compression ring assembly for a piston of an internal combustion engine includes a first compression ring and a second compression ring, with the second compression ring overlaid adjacent to and in abutting engagement with the first compression ring. When both the first compression ring and the se...

| description | A compression ring assembly for a piston of an internal combustion engine includes a first compression ring and a second compression ring, with the second compression ring overlaid adjacent to and in abutting engagement with the first compression ring. When both the first compression ring and the second compression ring are uncompressed and in a free state, the second compression ring includes an outer second ring diameter that is greater than an outer first ring diameter of the first compression ring. Additionally, the first compression ring includes a first radial width that is greater than a second radial width of the second compression ring. A first gap of the first compression ring is positioned relative to a second gap of the second compression ring in a non-overlapping orientation. |
