Amandla okuqhuba ukuthuthukiswa kobuchwepheshe bendandatho ye-piston avela ezicini ezimbili: Okokuqala, ukuthuthukiswa kwawo wonke umshini kukhuthaza inqubekelaphambili yobuchwepheshe bendandatho ye-piston. Njengoba izinga lokucwaninga elizimele kanye nentuthuko yawo wonke umshini lithuthuka, ubuchwepheshe beringi ye-piston nabo buzothuthuka. Okwesibili, izinkampani zamasongo e-piston zithatha umzila wobuchwepheshe obuphezulu futhi zikhuthaza ngenkuthalo ukusetshenziswa kobuchwepheshe obusha ukuqedela imishini. Umkhuba wokuthuthukiswa kobuchwepheshe wemboni ye-piston ring eminyakeni yamuva nje ukwenza insimbi yezinto ezibonakalayo, indandatho ye-piston ibe mncane, kanye nokwelashwa kwendawo ephezulu.

Ubuchwepheshe obusha baseChina bezindandatho zepiston busesesigabeni sokuhlola. Nakuba ubuchwepheshe obuhlukahlukene ngokwabo buvuthiwe, ucwaningo oluningi nokuhlola kuyadingeka ukuze kusetshenziswe emasongweni e-piston. Ubuchwepheshe obusha obuhlukahlukene bunobuhle kanye nebubi bazo, futhi okubalulekile ukuxazulula izinkinga zekhwalithi. Izinkampani zamaringi e-piston ngokuyisisekelo zithembele ekwethulweni kobuchwepheshe bangaphandle ukuze zithuthukise izinga lazo lobuchwepheshe.

Njengoba indandatho ye-piston ingeyona nje ingxenye eyinhloko yenjini, kodwa futhi enye yezingxenye ezinzima zokungqubuzana enjinini, indandatho yepiston iyadingeka ukuze ibe nokuncibilika okuphezulu nokumelana nokugqoka. Ukufuna izinto ezintsha kanye nezinqubo ezintsha zokwelashwa kwendawo sekuyinto okugxilwe kuyo kakhulu embonini ye-piston ring ukuze kuhlangatshezwane nezidingo zemakethe zesikhathi esizayo. Amasongo e-piston ezinjini zendabuko zezimoto zikadizili ngokuvamile asebenzisa i-ductile iron ne-alloy cast iron, kanti amasongo e-piston ezinjini zikaphethiloli ngokuvamile asebenzisa insimbi.

Ngenxa yokuthuthukiswa kwezinjini zezimoto ekuqondeni kwamandla aphezulu, ukuphuma okuphezulu nesisindo esincane, izindandatho ze-piston ziba mncane futhi zibe lula, okudinga amasongo e-piston ukuze abe namandla aphezulu. Esikhathini esedlule, izindandatho zensimbi zensimbi ezazisetshenziswa kakhulu ezinjinini zikaphethiloli zenziwa kancane kancane Emkhakheni wezinjini ze-diesel, ezinye izinjini ze-diesel zaqala ukusebenzisa izindandatho zamafutha ensimbi. Uma kuqhathaniswa namasongo ensimbi, amasongo ensimbi ayidingi inqubo yokulingisa, anesisindo esincane, futhi anezindlela ezilula zokucubungula. Abakhiqizi abajwayelekile batshale imali ekuthuthukiseni nasekukhiqizeni izindandatho zensimbi ezintsha. Ingxenye yamasongo ensimbi asetshenziswa embonini yezimoto zikadizili nayo iphezulu kakhulu.

Ukwanda kokuthunyelwa kwe-piston ring kuyisizathu esibalulekile sokwanda kokuthengiswa kweringi ye-piston. Ngenxa yobuningi bekhono lokukhiqiza laseShayina lamasongo e-piston namanani entengo emikhiqizo aphansi uma kuqhathaniswa, izinkampani eziningi eNingizimu-mpumalanga ye-Asia, eMpumalanga Ephakathi, e-Afrika, eRussia nakwamanye amazwe nasezifundeni zihehe izinkampani eziningi ukuthi zithenge eChina. Ngaphezu kwalokho, izinkampani ezivela eYurophu, e-United States, eJapane, eNingizimu Korea nakwamanye amazwe zisebenzisa abasebenzi baseChina abashibhile ukuze badlulisele ukukhiqizwa kwamasongo e-piston aphansi naphakathi nendawo eChina. Lokhu kulethe amathuba entuthuko angakaze abonwe ezinkampanini zamaringi zama-piston aseShayina.
