ABSTRACT:
A piston assembly for an internal combustion engine includes a piston having at least one annular compression ring groove within which is disposed a plurality of split piston rings. Each of the rings includes a ring gap and the rings are arranged in the groove with the respective gaps angularly misaligned and with adjacent flat surfaces of the rings contacting one another so as to close the gaps to prevent fluids from passing through the gaps when the piston operates in its cylinder bore.
