Indandatho yePiston iyindandatho yensimbi efakwe emseleni wepiston. Kunezinhlobo ezimbili zamasongo episton: indandatho yokucindezela kanye nendandatho kawoyela. Indandatho yokucindezela ingasetshenziswa ukuvala igesi exubile evuthayo ekamelweni lokushisa. Indandatho kawoyela isetshenziselwa ukuklwebha uwoyela owengeziwe kusilinda.
Indandatho yepiston uhlobo lwendandatho yensimbi enwebekayo enokuguquguquka okukhulu kokunwebeka kwangaphandle. Ihlanganiswe emseleni ojikelezayo ohambisana nephrofayili. Amasongo episton aphindaphindayo najikelezayo ancike ekwehlukeni kwengcindezi phakathi kwegesi noma uketshezi ukuze akhe uphawu phakathi kwendilinga yangaphandle yendandatho nesilinda kanye nohlangothi olulodwa lwendandatho nomsele.
Indandatho yepiston iyingxenye eyinhloko yenjini kaphethiloli. Ivala igesi kaphethiloli kanye nesilinda, i-piston kanye nodonga lwesilinda. Izinjini zezimoto ezisetshenziswa kakhulu zinezinhlobo ezimbili zenjini yedizili nephethiloli, ngenxa yokuthi ukusebenza kwayo kukaphethiloli kuhlukile, ukusetshenziswa kwamasongo episton akufani, indandatho yepiston yokuqala ngokukhipha, kodwa ngentuthuko yobuchwepheshe, kwazalwa indandatho yepiston enamandla aphezulu, futhi ngokuthuthuka okuqhubekayo komsebenzi wenjini, izidingo zemvelo, izinhlelo ezahlukene zokwelapha ubuso obuphambili, njengokufutha ngokushisa, i-electroplating, i-chrome plating, i-Gas nitriding, i-physical deposition, i-surface coating, i-zinc manganese phosphating treatment, ukuze umsebenzi wendandatho yepiston uthuthuke kakhulu.
