Amavuta yakoresheje he kuri mazutu ya mazutu ajya he? Igice cyacyo kijya kucyumba cyo gutwika kubera gufatanya amavuta kandi gitwikwa cyangwa ngo gitwike karubone, ikindi gice kiva mu mwanya kashe idakomera. Amavuta ya mazutu muri rusange yinjiye mucyumba cyo gutwika binyuze mu cyuho kiri hagati ya Piston Impeta ya Piston na Cheove Groove, kandi ikinamico hagati ya valve na duct. Impamvu itaziguye yo guhunga ni impeta yambere ya piston murwego rwo hejuru hafi yimigabane yacyo ibitonyanga bikabije, bizofatamo libricant hejuru yurugereko rwo gutwika. Kubwibyo, ibisobanuro hagati yimpeta ya piston na piston, ubushobozi bwa peteroli yo gukosora impeta ya piston, igitutu cyurugereko rwa Viston, igitutu cyurugereko rwo gutwika kandi urusyo rwamavuta rufitanye isano rya hafi nibikoresho bya peteroli.

Mubihe bifatika, viscosity yamavuta yakoreshejwe ni make cyane, igice cyihuta nubushyuhe bwa silinderi burenze urugero, umubare wibice bya kabiri bikambara cyane, amavuta Urwego ni hejuru cyane, nibindi. bizatuma ibicuruzwa byiyongera. Bitewe no kunyeganyega inkoni ihuza, kwiruka kwa piston byatewe no kwihanganira umubiri ntabwo byujuje ibyangombwa (ikimenyetso ni uruhande rwa banki ya piston kurundi ruhande skirt igaragara ko cylinder liner na piston bambara ibimenyetso), nibyo nimpamvu yingenzi yo kwiyongera mumavuta yamavuta.

Guhuza impamvu zavuzwe haruguru, urashobora kugenzura ibijyanye no gukoresha amavuta muburyo butandukanye hagati yicyunamo cya Piston Impeta na Piston, umuvuduko wicyumba, nibindi urashobora kandi gukoresha impeta yangiritse, bikagira ingaruka zigaragara mugugabanya ibiyobyabwenge.
