I-Piston Ring yintsimbi yentsimbi efakwe kwi-piston groove.Kukho iindidi ezimbini zamakhonkco episton: iringi yokucinezela kunye neringi yeoli.Iringi yokucinezela ingasetyenziselwa ukutywina igesi yomxube ovuthayo kwigumbi lokutsha.Iringi yeoli isetyenziselwa ukukhuhla ioyile engaphezulu kwicylinder.
Umsesane wepiston luhlobo lweringi yentsimbi eneelastiki enoguquko olukhulu lwangaphandle.Ihlanganiswe kwi-groove ye-annular ehambelana neprofayili.Amakhonkco episton abuyelayo kunye ajikelezayo axhomekeke kumahluko woxinzelelo phakathi kwegesi okanye ulwelo ukwenza itywina phakathi kwesangqa sangaphandle sendandatho kunye nesilinda kunye necala elinye lomsesane kunye negroove.
Iringi yepiston yinxalenye engundoqo ye-injini yamafutha.Itywina igesi yamafutha kunye necylinder, ipiston kunye nodonga lwesilinda.Iinjini zemoto ezisetyenziswa ngokuqhelekileyo zineentlobo ezimbini ze-diesel kunye ne-injini yepetroli, ngenxa yokusebenza kwayo kwamafutha yahlukile, ukusetyenziswa kwamakhonkco episton akufani, i-ringe yokuqala yepiston ngokuphosa, kodwa ngenkqubela phambili yobuchwepheshe, intsimbi yentsimbi ephezulu yazalwa, kunye nokuphuculwa okuqhubekayo komsebenzi we-injini, iimfuno zokusingqongileyo, iinkqubo ezahlukeneyo zonyango oluphezulu, ezifana nokutshiza nge-thermal, i-electroplating, i-chrome plating, i-nitriding yegesi, ukubekwa komzimba, ukugquma komhlaba, unyango lwe-zinc manganese phosphating, umsebenzi weringi piston uphuculwe kakhulu
