Uburyo bukoreshwa cyane muburyo bwa aluminium piston nuburyo bwa metero ya gravit graviting. By'umwihariko, icyuma kigezweho cyatangiye gutunganywa nibikoresho bya mashini ya CNC, bishobora kwemeza ubunini buke bwuzuye, umusaruro mwinshi nigiciro gito. Kuri cavit igoye ya piston, intoki yicyuma irashobora kugabanywamo ibice bitatu, bitanu cyangwa birindwi kugirango bibumbwe, bikaba bigoye kandi ntibiramba. Ubu buryo bwo gukwega imbaraga rimwe na rimwe butanga inenge nko gucamo ibice bishyushye, imyenge, pinholes, hamwe nubusa bwa piston yambaye ubusa.

Muri moteri ikomejwe, pisitori ya aluminiyumu yimpimbano irashobora gukoreshwa, yatunganije ibinyampeke, gukwirakwiza ibyuma neza, gukwirakwiza imbaraga, ibyuma byiza hamwe nubushuhe bwiza. Ubushyuhe bwa piston rero buri munsi yubwa gravit casting. Piston ifite uburebure burebure hamwe nubukomezi bwiza, bufite akamaro ko kugabanya imihangayiko. Nyamara, hypereutectic aluminium-silicon ivanze irimo silikoni irenga 18% ntabwo ikwiriye guhimbwa kubera ubugome bwabo, kandi guhimba bikunda gutera impagarara zisigaye muri piston. Kubwibyo, inzira yo guhimba, cyane cyane ubushyuhe bwa nyuma bwo guhimba hamwe nubushyuhe bwo kuvura ubushyuhe bigomba kuba bikwiye, kandi ibyinshi mubice muri piston yahimbwe mugihe cyo gukoreshwa biterwa no guhangayika. Guhimba bifite ibisabwa bikomeye kumiterere ya piston nigiciro kinini.

Amazi yo guhimba yapfuye yatangiye gukoreshwa mu musaruro hafi y’Intambara ya Kabiri y'Isi Yose, kandi yazamuwe mu ntera kandi ikoreshwa mu buryo butandukanye mu bihugu bitandukanye ku isi. Yageze ku iterambere ryihuse mu myaka icumi ishize. igihugu cyanjye cyatangiye gushyira mubikorwa iki gikorwa mu 1958 kandi gifite amateka yimyaka 40.

Amazi apfa kwibeshya ni ugusuka umubare munini wibyuma byamazi mubibumbano byicyuma, kanda igitutu, kugirango icyuma gisukuye cyuzuze umwobo kumuvuduko muto cyane ugereranije no gupfa, hanyuma koroha kandi igakomera mukibazo kugirango ubone ubucucike imiterere. Ibicuruzwa bitagabanije akavuyo, kugabanuka kwinshi nizindi nenge. Iyi nzira ifite ibiranga gukina no guhimba.
