COMBINATION OF PISTON RINGS AND COMBINED STRUCTURE OF PISTON AND PISTON RINGS

A combination of piston rings assembled to a piston includes a first compression ring, a second compression ring, a third compression ring and an oil ring. When an axial width of the first compression ring is h1(1), an axial width of the second compression ring is hl(2), an axial width of the third...

Zusammenfassung:	A combination of piston rings assembled to a piston includes a first compression ring, a second compression ring, a third compression ring and an oil ring. When an axial width of the first compression ring is h1(1), an axial width of the second compression ring is hl(2), an axial width of the third compression ring is hl(3) and an axial width of the oil ring is h1(4), h1(1) ≥ h1(2) and h1(1) ≥ h1(3), and when hl(TOTAL) = h1(1) + h1(2) + h1(3) + h1(4), h1(TOTAL) ≥ 3.1 mm.
