Piston-cylinder set for reciprocating internal-combustion engines, especially Otto and diesel engines

摘要: To avoid the necessity of piston rings in a piston-cylinder set, it is prsed that cylinder liner be surrounded by band consisting fiber composite whose thermal expansion radial direction less than liner, impediment to presented varying over length housing; constructed with cap head facing combustion chamber and an essentially cylindrical skirt adjacent bearing surface, force-transmitting core contains for pin spherical pressure pad; connection rotationally symmetrical piston's longitudinal axis provided above connected at lower edge core, but otherwise no contact between except area connection; both fabricated from ceramic material.
