Imbaraga za elastike zimpeta ya piston nikintu cyingenzi kigira ingaruka kumavuta yo guterwa numuyoboro usohoka. Ubworoherane bwimpeta ya piston burashobora kugenzurwa nigeragezwa ryimpeshyi cyangwa uburyo bwo kugereranya. Muri iki gihe, impeta ya piston ishaje nimpeta ya piston irashobora gushirwaho hamwe, kandi igitutu gishobora gukoreshwa uhereye hejuru ukoresheje intoki. Niba ibyambu byimpeta bishaje bihuye kandi ibyambu bishya byimpeta biracyafite icyuho kinini, bivuze ko impeta ya piston ifite elastique mbi. Reba aho uhurira no gufunga impeta ya piston hamwe na silinderi: Shira impeta ya piston iringaniye mumurongo wa silinderi, shyira itara munsi yimpeta ya piston, hanyuma ushyiremo ingabo yumucyo kugirango urebe urumuri rutemba hamwe na kashe ya impeta ya piston mumurongo wa silinderi.

Icyifuzo rusange muri rusange nuko mugihe upimye icyuho cyurumuri rwa piston nimpeta yubunini, ntigomba kurenga 0.03mm. Impeta ya piston irazunguruka kubera kunyeganyega mugihe ikora. Ibi ni ibintu bisanzwe. Moteri imaze gushiraho silinderi nshya mugihe ushyira piston ihuza inteko. Igihe cyose impeta ya piston igabanijwemo impande zagenwe, gufungura impeta za piston ntizizunguruka ngo zuzuzanye. Iyo silinderi ikora ellipse na taper kubera kwambara igice cyangwa kwambara cyane kwa piston, birashoboka ko gufungura impeta ya piston bihindukirira icyerekezo kimwe kugeza kuri ellipse. Kuberako muri iki gihe, kubera ellipse yumurongo wa silinderi, kwaguka kwifunguye rya piston birabujijwe kuzunguruka, bigatuma gufungura impeta bigenda byuzura buhoro buhoro, gaze iramanuka epfo, kandi amavuta ya moteri arahunga hejuru arasohoka.

Iyo inkoni ihuza igoretse kandi igahinduka, gutandukanya piston na silinderi ni binini cyane, kandi ikinyuranyo cyo gufungura impeta ya piston nini cyane, gishobora no gutera umwuka, bigatuma kwimura impeta ya piston bigakora a couple. EQ6100-1 moteri ya piston impeta yo gusimbuza igihe: hagati yo kuvugurura moteri ebyiri, imodoka ikora ibirometero 80.000, ibyo bikaba bihwanye na 0.15mm yimyenda ya silinderi, cyangwa icyuho cyanyuma cyimpeta ya piston irenga 2mm; imbaraga za moteri Imikorere iragabanuka cyane, gukoresha lisansi namavuta yo kwisiga byiyongera cyane, icyuma cyumuriro gikunda kubikwa na karubone, kandi impeta ya piston iracika. Mugihe uhitamo impeta ya piston, impeta ya piston yo murwego rumwe na piston igomba gukoreshwa.
