Moteri ikeneye kunyunyuza umwuka mwinshi mugihe cyakazi.Niba umwuka utayungurujwe, umukungugu uhagaritswe mukirere uzanyunyuzwa muri silinderi, bizihutisha kwambara kwitsinda rya piston na silinderi.Ibice binini byinjira hagati ya piston na silinderi birashobora gutera "gukurura silinderi" ikomeye, ikomeye cyane mubikorwa byumye kandi byumucanga.Akayunguruzo ko mu kirere gashyizwe imbere ya carburetor cyangwa umuyoboro ufata kugirango ushungure umukungugu n'umucanga mu kirere, urebe ko umwuka uhagije kandi usukuye winjira muri silinderi
Ukurikije ihame ryo kuyungurura, akayunguruzo ko mu kirere gashobora kugabanywamo ubwoko bwa filteri, ubwoko bwa centrifugal, ubwoko bwogeramo amavuta nubwoko bwa compte.
Mugihe cyo kubungabunga, impapuro zungurura impapuro ntizigomba guhanagurwa mumavuta, bitabaye ibyo ibintu byo kuyungurura impapuro bizananirana, kandi biroroshye guteza impanuka yihuta.Mugihe cyo kubungabunga, gusa uburyo bwo kunyeganyega, uburyo bworoshye bwo gukuraho brush (gukaraba hejuru yiminkanyari) cyangwa uburyo bwo guhumeka ikirere gishobora gukoreshwa gusa mugukuraho umukungugu numwanda bifatanye hejuru yikintu cyo kuyungurura impapuro.Kubice biyungurura igice, umukungugu mubice bikusanya ivumbi, ibyuma hamwe numuyoboro wa cyclone bigomba kuvaho mugihe.Nubwo ishobora kubungabungwa neza buri gihe, impapuro zungurura ibintu ntizishobora kugarura neza imikorere yumwimerere, kandi imbaraga zo gufata ikirere ziziyongera.Kubwibyo, muri rusange, mugihe impapuro zungurura ibintu bigomba kubungabungwa kunshuro ya kane, bigomba gusimburwa nibintu bishya byungurura.Niba impapuro zungurura ibintu zacitse, zisobekeranye, cyangwa impapuro zo kuyungurura hamwe numutwe wanyuma wangiritse, bigomba guhita bisimburwa.
