1. Indima yePiston
I-piston i-piston yinxalenye ebalulekileyo ye-injini yedieli yaseMarine, imisebenzi ephambili ibandakanya:

Itywina: ethintela igumbi lokuhlambela kwi-gesi yokudibanisa kwi-cranksest kwaye ugcine uxinzelelo lokucinezelwa.

Utshintshelo lobushushu: Yenza ubushushu be-piston ukuya eludongeni lwe-cylinder ukuya kunceda ukupholisa.

Ulawulo lweoyile: Lungisa isixa seoyile esithambisa i-oyile kwi-sylinder dooll ukuthintela ioyile eninzi ukungena kwigumbi lokudibana.

Inkxaso: Kunciphisa ukungqubana nokunxiba phakathi kwe-piston kunye nodonga lwesilinda.

I-2. Uhlobo lwe-piston iringi
I-ring yegesi (iringi yokunyanzelwa): isetyenziselwa ukutywina i-gesing gesi yokudibanisa ukukhusela ukuvuza.

Iringi yeoli: ilawula ioyile ethambisayo kudonga lwesilinda ukunqanda ioyile engaphezulu kokungena kwigumbi lokudibana.

I-3. Izixhobo kunye nemveliso
Izixhobo: Izinto ezisetyenziswa ngokuqhelekileyo ziquka i-iron, i-alloy, intsimbi, njl njl.

Inkqubo yokwenza imveliso: Ukucamngca ngokuchanekileyo, unyango lobushushu kunye nonyango oluphezulu (njengokubekwa kwe-chrome, i-nit) zihlala zisetyenziselwa ukuphucula ukusebenza.
