Iquka ntoni indibano yepiston?
Ipiston inesithsaba sepiston, intloko yepiston kunye nesiketi sepiston:
1. Isithsaba sePiston siyinxalenye ebalulekileyo yegumbi lokutsha, elihlala lisenziwa kwiimilo ezahlukeneyo. Umzekelo, isithsaba se-piston ye-injini yepetroli ithatha kakhulu umphezulu osicaba okanye umphezulu we-concave, ukwenzela ukuba igumbi lokutsha lihlangane kunye nendawo encinci yokulahla ubushushu;
2. Inxalenye phakathi kwesithsaba sepiston kunye neyona ndawo iphantsi yepiston ring groove ibizwa ngokuba yintloko yepiston, esetyenziselwa ukuthwala uxinzelelo lwegesi, ukuthintela ukuvuza komoya, kunye nokudlulisa ubushushu kudonga lwesilinda ngeringi yepiston. Intloko yepiston isikwe ngeegrooves ezininzi zokubeka umsesane wepiston;
3. Zonke iindawo ezingaphantsi kwe-piston ring groove zibizwa ngokuba yi-piston skirt, esetyenziselwa ukukhokela i-piston ukwenza i-reciprocating motion kwi-cylinder kunye ne-bear side pressure.
