Akayunguruzo ka moteri nikintu cyingenzi mumodoka hamwe na sisitemu zitandukanye zo gutwika imbere. Igikorwa cyibanze ni ugushungura neza umwanda, kwemeza ibidukikije bikora neza kandi bihamye muri moteri. Nka "umunyezamu" wa powertrain, akayunguruzo gahindura imikorere ya moteri, igihe cyo kubaho, hamwe nubwizerwe bwibinyabiziga muri rusange.
Ubwa mbere, akayunguruzo ko mu kirere gashinzwe gukumira ivumbi, amabyi, hamwe n’ibintu biva mu kirere byinjira mu cyumba cyaka. Niba utwo duhumekero duto twinjiye mu muriro udafunguye, birashobora kwihutisha kwambara kuri silinderi no ku mpeta za piston, ndetse bigatera no kubitsa valve, bikagabanya gukora neza. Imashini zigezweho - moteri yimikorere isaba umwuka mwinshi cyane. Akayunguruzo keza - gashobora kuzamura ubukungu bwa peteroli no kugabanya ibyuka bihumanya.
Icya kabiri, akayunguruzo k'amavuta kagumana isuku ya sisitemu yo gusiga ukuraho imyanda, colloide, na oxyde mumavuta ya moteri. Iyo moteri ikora, guterana hagati yimuka ibyara umwanda mwinshi. Niba ibyo bihumanya bigenda bikwirakwira cyangwa bifashe, birashobora gutera kunanirwa gukomeye. Guhindura buri gihe amavuta yo kuyungurura nigipimo cyingenzi cyo kongera ubuzima bwa moteri. Byongeye kandi, akayunguruzo ka lisansi gakuraho ubushuhe, colloide, hamwe nuduce duto twa mazutu na lisansi, bikarinda inshinge gufunga umurongo wa lisansi. Iyi mikorere irahambaye cyane mubidukikije bya - byiza bya peteroli, birinda neza moteri ya moteri no gutakaza ingufu.
Muri make, moteri ya filteri itanga uburinzi bwuzuye kuri powertrain binyuze muburyo bwo kwirwanaho. Kwirengagiza gufata neza filteri birashobora kuvamo amafaranga menshi yo gusana, mugihe kugenzura buri gihe kuyungurura no kuyisimbuza nibyingenzi kugirango ibinyabiziga bikore neza kandi bifite umutekano.
