Ubusobanuro nyamukuru bwuruhererekane rwibihe ni ugukwirakwiza ingufu ziva muri crankshaft kugirango utware uburyo bwa valve ya moteri yimodoka kugirango tumenye neza ko piston ya silinderi ya moteri yimodoka ishobora kuzuza imirongo ine yo gufata, gutwikwa, akazi, no kunanirwa, kugirango tumenye imikorere isanzwe ya moteri yimodoka. Akazi, sisitemu yose igizwe nibikoresho, iminyururu nibikoresho bikurura. Muri byo, hydraulic tensioner irashobora guhita ihindura imbaraga zoguhagarika umutima, kugirango impagarara zuruhererekane zihamye, ntabwo umutekano gusa nubwizerwe byatejwe imbere kurwego runaka, ariko kandi no gukoresha moteri, Igiciro cyo kubungabunga cyaragabanutse a byinshi, bishobora gusobanurwa nkinyungu nyinshi muburyo bumwe.

Nibihe bimenyetso biranga urunigi rurerure?

Muri rusange, urunigi rwigihe ntiruzacika, ruzaramba gusa. Niba urunigi rurerure, hazabaho ibintu bidasanzwe, nkurumuri rwamakosa rwaka, urusaku rudasanzwe rugaragara iyo rudakora, kandi urunigi ruzasimbuka amenyo nyuma yo kuramba. Bizangiza kandi moteri hejuru ya valve. Kubera impagarara, nyuma yumunyururu urambuye, umutambiko uzunguruka hanze kandi ukomeze gukomera urunigi. Iyo impagarike ihinduwe kumupaka, urunigi ntirushobora guhinduka niba rurambuye, kandi rugomba gusimburwa muriki gihe.

Nibirometero bingahe bikwiye guhinduka?

Birashobora kuvugwa ko ubuzima bwa serivisi bwigihe cyigihe kirekire. Imodoka zimwe ntizikeneye gusimburwa mugihe zavanyweho, kandi imodoka zimwe zigomba gusimburwa niba zitarenze kilometero 100.000. Bitabaye ibyo, imodoka ntishobora gukoreshwa mubisanzwe. Ubuzima bwa serivisi bwurutonde rwibihe muri rusange ni kilometero 150.000 kugeza 200.000. Niba imodoka iremerewe igihe kinini kumuvuduko mwinshi, igomba kugenzurwa mumyaka 5 cyangwa kilometero 75.000. Niba yambaye cyane cyangwa yangiritse, igomba gusimburwa mugihe. Niba utwaye neza witonze kandi umutwaro ku modoka ugereranije ni muto, ubuzima bwa serivisi bwumunyururu buzaba burebure.

Muri rusange, kwizerwa kumurongo wigihe ni hejuru cyane. Biracyaterwa nibidukikije byo gutwara nibindi bintu byingenzi byo hanze. Igenzurwa ku gihe ukurikije ibihe byo gukoresha n’ibidukikije, igasimburwa igihe bibaye ngombwa.
