Iki cyumweru, Rymax Rwanda yatangije ku mugaragaro Porogaramu nshya yo gukurikirana imiterere y’amavuta (Oil Condition Monitoring Program), itangiriye kuri Mota Engil, umwe mu bafatanyabikorwa bacu bakomeye mu bikorwa by’ubucuruzi n’inganda.

Uruganda Africa Lubricant Manufacturing Company Ltd (ALMC) rwateguye amahugurwa mu Rwanda agamije gufasha abakanishi, abacuruzi n’abashoramari kumenya no gukoresha neza amavuta ya Rymax, bityo bongere ubumenyi bwabo n’amahirwe yo gutera imbere mu bucuruzi.

Mubiganiro byacu bya blog 'imyumvire y'abantu ku modoka' turasesengura ibitekerezo bitandukanye byimodoka. Turareba icyo imodoka zisobanura kubantu, icyo imodoka zizwiho na siporo yimodoka zihari, nuburyo zifata imodoka zabo mubihugu bitandukanye. Iki gihe Yvette aravuga kubyerekeye imyumvire y'abantu ku modoka mu Rwanda. Ari mu Rwanda akaba atuye Kigali.

Imodoka y’amasiganwa isaba amavuta no kwitabawaho byihariye butandukanye n’imodoka zisanzwe. Nubwo imodoka zisanzwe zikorewe gukoreshwa umunsi kumunsi, aho inyungu nk’imikoreshereze ya lisansi no kukora neza bigira uruhare runini, imodoka y’amasiganwa ifite intego yo gutanga imbaraga nyinshi mu buryo bwihariye. Akenshi, amashini, amapine, moteri, susipansiyo, imbere, n’imikorere ya aerodinamike byakosowe kugira ngo habeho umusaruro mwiza. Ubusanzwe ibikoresho bikoresha mu modoka y’amasiganwa bikenera kurindwa cyane kandi bisaba amavuta meza bishoboka. Gukoresha amavuta afite ibipimo bitandukanye gato n’ibisabwa bishobora gutera igihombo mu mikorere cyangwa kugera ku bice byangiritse.

Imodoka z’amasiganwa zitandukaniye cyane n’imodoka zisanzwe, cyane cyane ku bijyanye n’imikoreshereze y’amavuta. Imodoka zisanzwe zagenewe gukoreshwa buri munsi, aho imikoreshereze y’ibikomoka kuri peteroli (fuel economy) n’imodoka itanga ihumure ari iby'ingenzi. Ariko imodoka y’amasiganwa yo iba yarakozwe hagamijwe gutanga umusaruro n’umusaruro ku rugero rwo hejuru, igakoreshwa ku mugambi runaka.

Buri muruganda rw’imodoka rwemera guhindura amavuta nyuma y’ibilometero runaka. Amavuta afite inshingano zitandukanye, nka kurinda, gusukura, no gukonjesha moteri. Ariko se, ni ibihe bishobora kubaho iyo utubahirije igihe cyo guhindura amavuta cyangwa se ukaba utahindura amavuta ya moteri na gato? Dore ibyakurikiraho:

Mu myaka mirongo itandatu ishize, guhindura amavuta ya moteri ku modoka z'amakamyo byakorwaga kenshi buri 800 – 1000 km.

Mu bijyanye no gufata neza imodoka yawe, gukoresha amavuta ya moteri akwiye ni ingenzi cyane. Abakunzi b’imodoka bazi ko amavuta meza ashobora kongera igihe moteri imara no kuyifasha gukora neza. Ariko iyo ushakisha inama ku mavuta ya moteri kuri internet, ushobora gusanga amakuru anyuranye, rimwe na rimwe ahabanye. None se ni gute wahitamo ukuri hagati y’ibihimbano? Iyo ukurikije amakuru atari yo, ushobora kwangiza moteri yawe bigatuma ugira igihombo gikomeye. Muri iyi nkuru, turasesengura imyumvire itariyo y'ingenzi itanu ku mavuta ya moteri kugira ngo umenye ukuri n’ibihimbano.

SAE 5W-30. SAE 10W-40. Ayo magambo asobanuye iki?

Twebwe kuri Rymax twishimiye gutangaza ubufatanye bwacu na Adwuma Ye, umuryango w’abagiraneza ukora ubudacogora mu kuzamura imibereho y’imiryango itishoboye muri Gana. Ubufatanye bwacu bugamije gushyigikira imbaraga za Adwuma Ye mu gutanga amahirwe yo kwiga, ubuvuzi, n’izindi serivisi zingenzi ku bakeneye ubufasha.

Muri iki gihe, hari ubwoko bwinshi bw’amavuta ya grease aboneka ku isoko, buri bwoko bukaba bwakozwe hagamijwe gukemura ibibazo bitandukanye. Kugira ubumenyi bw’ibanze kuri grease no ku ikoreshwa ryayo ni ingenzi mu gufata umwanzuro ukwiye. Mbere yo gutangira, ni byiza gusobanukirwa neza grease icyo ari cyo.

Transmission bivuze agasanduku k’amasenge (gearbox) gakoresha amasenge n’urusobe rw’amasenge kugira ngo habeho guhindura umuvuduko n’imbaraga (torque) bivuye kuri moteri bijya ku mapine y’imodoka (wheels). Transmission fluid ni amavuta akoreshwa mu gusiga no kurinda ibice bigize transmission y’imodoka kugira ngo ikore neza.

Nk'uko amazina yabyo abyerekana, amavuta y'imodoka ziremereye (akoreshwa mu gutwara ibicuruzwa, ubuhinzi cyangwa ubucukuzi bw’amabuye y’agaciro, azwi nka HDDEO’s) n’amavuta y’imodoka zisanzwe akoreshwa mu modoka z’abantu bafite intego zitandukanye. Ariko se, ni irihe tandukaniro mu miterere y’aya mavuta, kandi kuki ibisabwa ku mavuta akoreshwa mu mashini ziremereye bitandukanye n’ibisabwa ku mavuta y’imodoka zisanzwe?

Hari impaka nyinshi ku bijyanye n’icyaba cyiza hagati yo gukoresha azote cyangwa umwuka usanzwe mu mapine. Gukoresha azote bizwiho inyungu zimwe nk’izamara igihe kinini ifasha kugumana umuvuduko w’ipine udahinduka cyane, guhindagurika gake bitewe n’ubushyuhe, ndetse no kugabanya ikoreshwa ry’ibikomoka kuri peteroli.

Amavuta ya feri ni ubwoko bw’amavuta ya hydraulic akoreshwa muri feri za hydraulic no muri clutch za hydraulic mu modoka. Afite inshingano zo guhindura imbaraga mo umuvuduko no kongera imbaraga zo guhagarika imodoka. Mu magambo make, iyo ukandagije akaguru kuri pedali ya feri, amavuta ya feri ahindura iyo mbaraga mo umuvuduko, ugahita woherezwa kuri feri y’imbere n’iy’inyuma, bityo imodoka igahagarara. Ibi bishoboka ku amavuta kuko ntaburyo bwo kuyegeranya ngo abe mato buhari.
