Piston anulum est metallum anulum inserta in Piston sulcus. Sunt duo genera Piston Annulorum: compressionem Orbis et oleum circulum. Et compressio anulus potest ad signare combustible mixturam Gas in combustione cubiculum. Et oleum anulum adhibetur ad rade excessus oleum de cylindro.
Piston anulus est quaedam metallum elastica anulum cum magna exteriori expansion deformatio. Convenerunt in annularis sulcus respondens ad profile. Reciprocating et rotating Piston annulos confidunt in pressura differentia inter Gas aut liquidum ad formare sigillum inter exteriores circulus circulum et cylindrum et latus circuli et sulcus.
Piston anulus est core pars cibus engine. Sigils cibus Gas cum cylindri Piston et cylindri murum. Commonly used automotive engines have two kinds of diesel and gasoline engine, due to its fuel performance is different, the use of piston rings are not the same, the early piston ring by casting, but with the progress of technology, steel high power piston ring was born, and with the continuous improvement of engine function, environmental requirements, a variety of advanced surface treatment applications, such as thermal spraying, electroplating, chrome plating, Gas nitriding, corporalis depositionem, superficiem coating, cadmiae manganese phosphaiving curatio, ut munus in Piston anulus est valde melius
