Ihame ryakazi ryuburyo butatu bwa catalitike ihindura ni: mugihe ubushyuhe bwo hejuru bwumuduga wimodoka ukoresheje igikoresho cyo kweza, isuku mumashanyarazi atatu ya catalitike ihindura ibikorwa byubwoko butatu bwa gaze CO, hydrocarbone na NOx, guteza imbere okiside - kugabanya imiti ya chimique, aho okiside ya CO ku bushyuhe bwo hejuru ihinduka ibara, gaze ya gaze karuboni idafite uburozi; 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 ntishobora kubora no gutwikwa, bityo hamwe n’imyuka y’imyanda, imyanda nayo izashyirwa kuri ubuso bwa sensor ya ogisijeni hamwe na bitatu bya catalitike ihindura. Biterwa nibintu byinshi bituma imodoka nyuma yo gutwara mugihe cyibirometero, usibye kwirundanya kwa karubone muri valve yinjira no mucyumba cyaka, bizanatera sensor ya ogisijeni hamwe n’uburyo butatu bwa catalitike ihindura uburozi, inzira eshatu guhagarika catalitike ihagarika hamwe na valve ya EGR ihagarikwa nubutaka bwatsinzwe nibindi byananiranye, bikavamo gukora moteri idasanzwe, bigatuma ikoreshwa rya lisansi ryiyongera, kugabanuka kwamashanyarazi hamwe numuriro urenze ibisanzwe nibindi bibazo.
Imashini gakondo ibungabungwa bigarukira 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 na sisitemu yo kuzimya, cyane cyane ibisabwa byo kubungabunga sisitemu yo kugenzura ibyuka bihumanya. 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.
