Akayunguruzo ko mu kirere ni umuryango wa silinderi ihumeka umwuka mwiza.Igikorwa cyayo ni ugukuraho umukungugu nindi mwanda mwuka winjira muri silinderi kugirango ugabanye kwambara ibice bitandukanye muri silinderi.Ibi bigomba gukurura ibitekerezo byabakozi.

Kuberako umukungugu munini ugizwe na quartz nuduce twinshi, iyo zinjiye muri silinderi, bizatera kwambara cyane ibice nkuko abrasives yongewe kuri buri gice cyo guhuza silinderi.Ibizamini byagaragaje ko niba amashanyarazi ya mazutu adashyizwemo akayunguruzo ko mu kirere, ingaruka ni: kwambara silinderi byikubye inshuro 8, kwambara piston byiyongera inshuro 3, no kwambara impeta ya piston yongerewe inshuro 9.

Birashobora kugaragara ko akayunguruzo ko mu kirere gafite uruhare runini mubuzima bwumurimo wa moteri ya mazutu, kandi akayunguruzo ko mu kirere ntikemerewe gukurwa uko bishakiye mugihe cyo kuyikoresha.Muri icyo gihe, akayunguruzo ko mu kirere kagomba gusukurwa no kubungabungwa mu gihe ukurikije ingano y’umukungugu uri mu kirere aho ikoreshwa kugira ngo urugi rugende neza, byujuje ibisabwa na moteri ya mazutu yashyizweho umwuka wo gufata, kandi wirinde kunanirwa kwinshi guterwa nawo (Nkugusenyera intege nke, imbaraga zidahagije, umwotsi wumukara uturuka, nibindi).
