Indandatho yePiston yindandatho yesinyithi efakwe kwi-groove yepiston. Kukho iintlobo ezimbini zeendandatho zepiston: indandatho yoxinzelelo kunye nendandatho yeoyile. Indandatho yoxinzelelo ingasetyenziselwa ukuvala igesi yomxube ovuthayo kwigumbi lokutsha. Indandatho yeoyile isetyenziselwa ukukrazula ioyile engaphezulu kwisilinda.
Indandatho yepiston luhlobo lwendandatho yesinyithi elastiki ene-deformation enkulu yangaphandle. Idityaniswe kwi-groove ejikelezayo ehambelana neprofayili. Indandatho yepiston ejikelezayo nejikajikayo ixhomekeke kumahluko woxinzelelo phakathi kwegesi okanye ulwelo ukwenza uphawu phakathi kwesangqa sangaphandle sendandatho kunye nesilinda kunye necala elinye lendandatho kunye ne-groove.
Indandatho yepiston yinxalenye ephambili yenjini yepetroli. Ivala igesi yepetroli kunye nesilinda, ipiston kunye nodonga lwesilinda. Iinjini zeemoto ezisetyenziswa rhoqo zineentlobo ezimbini zeenjini zedizili kunye nepetroli, ngenxa yokuba ukusebenza kwayo kwamafutha kwahlukile, ukusetyenziswa kweendandatho zepiston akufani, indandatho yepiston yokuqala ngokuyila, kodwa ngenkqubela phambili yetekhnoloji, indandatho yepiston enamandla aphezulu yazalwa, kwaye ngokuphuculwa okuqhubekayo komsebenzi wenjini, iimfuno zokusingqongileyo, iintlobo ngeentlobo zezicelo zonyango lomphezulu ophezulu, ezifana nokutshiza ngobushushu, i-electroplating, i-chrome plating, i-Gas nitriding, i-physical deposition, i-surface coating, i-zinc manganese phosphating treatment, ukuze umsebenzi wendandatho yepiston uphuculwe kakhulu.
