Imikorere ya moteri ya mazutu irangizwa na buri silinderi nayo, imbaraga rero zikora kuri crankshaft nazo zigenda zisimburana kandi zitaringanijwe. Kugirango wohereze izo mbaraga neza, kuzunguruka kwa crankshaft ubwabyo bigomba kuba bihamye. Kugirango ihamye, igikonjo kigomba kuringanizwa. Crankshaft ijyanye no gutunganya umubare wa silinderi.

Kuri crankshafts ya moteri eshatu-, enye-, eshanu, na karindwi-ya moteri ya mazutu, uburemere buringaniye burasabwa kugirango igikonjo kibone uburemere buringaniye. Ingano nuburyo byuburemere buringaniye bibarwa mugihe cyo gushushanya. Ibyinshi muburemere buringaniye bwa crankshafts bihujwe na crankshaft mugihe uhimba cyangwa utera. Muri imwe. Nyamara, uburemere buringaniye bwa moteri ya mazutu ihindurwamo crankshaft. Bitewe nubunini bugereranije bwubwoko buringaniye, gufunga bolt bikoreshwa mugihe umwanya wo kwishyiriraho udahagije.

Kuri moteri ihagaritse itandatu ya moteri ya mazutu ifite inguni ya 120, ingaruka zingana ni nziza. Birasa nkaho bidakenewe gushiraho uburemere buringaniye. Nyamara, iyi mpirimbanyi nigisubizo cyimbaraga za inertia kumurongo wa crankshaft cyangwa silinderi. Kubijyanye na moteri ya mazutu, haracyari imbaraga nyinshi zidafite imbaraga, rimwe na rimwe bigatuma imiyoboro nyamukuru iremererwa cyane cyangwa blok ya silinderi ikanyeganyega.

Kugirango wirinde kunanirwa gutya, buri gice cya crankshaft gifite imbaraga nini zidafite imbaraga, kuburyo haracyariho kuringaniza. Kuburemere buringaniye bufatanye na bolts, mugihe igikonjo gikeneye kuba hasi, uburemere buringaniye bugomba gukurwaho kandi bugashyirwaho ikimenyetso kugirango wirinde kwishyiriraho nabi kutavunika umunzani mugihe wongeye kugarura.
