I-Piston Ring yindandatho yensimbi efakwe ku-piston groove. Kunezinhlobo ezimbili zama-piston izindandatho: ukukhala kwendandatho kanye nendandatho kawoyela. Indandatho yokucindezela ingasetshenziswa ukubeka uphawu igesi ehlanganisiwe yengxube egumbini lokuhlanganisa. Indandatho kawoyela isetshenziselwa ukuklama uwoyela owengeziwe kwisilinda.
I-Piston Ring uhlobo lwentengiso yensimbi enensimbi enoguquko olukhulu lwangaphandle lwangaphandle. Kuhlanganiswe kwi-groove yonyaka ehambelana nephrofayili. Izindandatho ze-piston ezivunayo zincike emngceleni wengcindezi phakathi kwegesi noma uketshezi ukwakha uphawu phakathi kombuthano wangaphandle wendandatho nesilinda kanye ne-groove eyodwa.
Indandatho yePiston iyingxenye ebalulekile yenjini yamafutha. Ivala igesi kaphethiloli kanye nesilinda, i-piston kanye nodonga lwe-cylinder. Izinjini zezimoto ezivame ukusetshenziswa zinezinhlobo ezimbili zenjini yedizili nephethiloli, ngenxa yokusebenza kwalo kwamafutha kuhlukile, ukusetshenziswa kwendandatho ye-piston kungukuphola, izidingo zensimbi eziphakemeyo ngokuzithandela, okuhlotshiswe nge-chron, iplanethi ye-chrome, i-nitring ye-chrome, Ukubekwa ngokomzimba, ukuhlanganiswa komhlaba, i-zinc mangese phosphating ukwelashwa, ukuze umsebenzi wanda kwendandatho uthuthuke kakhulu
