Ihame ryakazi ryuburyo butatu bwa catalitike ihindura ni: mugihe ubushyuhe bwinshi bwumuriro wimodoka unyuze mugikoresho cyo kweza, isuku mumashanyarazi atatu ya catalitike ihindura ibikorwa byubwoko butatu bwa gaze CO, hydrocarbone na NOx, kugirango iteze imbere okiside - kugabanya reaction ya chimique, aho okiside ya CO mubushuhe bwa gaze karuboni; Hydrocarbone ihindura amazi (H2O) na dioxyde de carbone ku bushyuhe bwinshi; NOx yagabanutse kuri azote na ogisijeni. Ubwoko butatu bwa gaze yangiza muri gaze itagira ingaruka, kugirango umwuka wimodoka ushobora kwezwa. Dufate ko hakiri ogisijeni iboneka, igipimo cya peteroli yo mu kirere irumvikana.
Bitewe n'ubuziranenge bwa peteroli mu Bushinwa, lisansi irimo sulfure, fosifore na antiknock agent MMT irimo manganese. Ibi bikoresho bigize imiti bizakora uruganda rukora imiti hejuru ya ogisijeni ya ogisijeni no imbere mu buryo butatu bwa catalitiki ihindura hamwe na gaze ya gaze isohoka nyuma yo gutwikwa. Byongeye kandi, bitewe nubushoferi bubi bwo gutwara, cyangwa gutwara igihe kirekire mumihanda yuzuye, moteri ikunze kuba mumuriro utuzuye, bizatera karubone mumashanyarazi ya ogisijeni hamwe na catalitike yinzira eshatu. Byongeye kandi, uduce twinshi tw’igihugu dukoresha lisansi ya Ethanol, ifite ingaruka zikomeye zo gukora isuku, izahanagura igipimo mu cyumba cyaka ariko ntigishobora kubora no gutwikwa, bityo hamwe n’imyuka y’imyanda y’imyanda, iyi myanda nayo izashyirwa hejuru y’icyuma cya ogisijeni hamwe n’imihindagurikire y’inzira eshatu. Biterwa nibintu byinshi bituma imodoka nyuma yo gutwara mumirometero mike, usibye kwirundanya kwa karubone mumatara yo gufata hamwe nicyumba cyaka, bizanatera sensor ya ogisijeni hamwe nuburyo butatu bwa catalitiki ihindura uburozi, guhagarika inzira ya catalitike ihindagurika hamwe na EGR valve ihagarikwa nubutaka bwangiritse hamwe nibindi byananiranye, bikaviramo kwiyongera kwamavuta, kugabanuka no kugabanuka.
Imashini gakondo ibungabungwa isanzwe igarukira gusa kubikorwa byibanze byo gusiga amavuta, sisitemu yo gufata hamwe na sisitemu yo gutanga lisansi, ariko ntishobora kuzuza ibisabwa byuzuye byo kubungabunga moteri igezweho yo gusiga amavuta, sisitemu yo gufata, sisitemu yo gutanga lisansi hamwe na sisitemu yo gusohora, cyane cyane ibisabwa byo kubungabunga imyuka ihumanya ikirere. Kubwibyo, niyo ikinyabiziga cyaba igihe kirekire gisanzwe gisanzwe, biragoye kwirinda ibibazo byavuzwe haruguru.
Mu gusubiza ayo makosa, ingamba zafashwe n’ibigo byita ku busanzwe ni ugusimbuza ibyuma bya ogisijeni hamwe n’ibice bitatu bya catalitiki ihindura. Ariko, kubera ikibazo cyigiciro cyo gusimburwa, amakimbirane hagati yinganda zita kubakiriya arakomeza. By'umwihariko abadafite ubuzima bwa serivisi bwo gusimbuza ibyuma bya ogisijeni hamwe na catalitike ihindura inzira eshatu, akenshi usanga byibandwaho mu makimbirane, abakiriya benshi ndetse bavuga ko ikibazo ari ubwiza bw’imodoka.
