Ihame ry'imikorere rya "catalytic converter" y'inzira eshatu ni iri: iyo ubushyuhe bwinshi bw'imyotsi iva mu modoka inyuze mu gikoresho cyo kuyisukura, "cleaner" iri muri "catalytic converter" y'inzira eshatu izongera imikorere y'ubwoko butatu bwa gaze CO, hidrokaboni na NOx, kugira ngo irusheho gukora neza, aho "oxidation" ya CO ku bushyuhe bwinshi iba gaze ya dioxyde de carbone idafite ibara, idahumanya; Hydrocarbons zigahinduka amazi (H2O) na dioxyde de carbone ku bushyuhe bwinshi; NOx igabanywa ikaba azote na ogisijeni. Ubwoko butatu bwa gaze mbi buhinduka gaze idahumanya, kugira ngo imyuka iva mu modoka ishobore gusukurwa. Dufashe ko hakiri ogisijeni, igipimo cy'umwuka na lisansi kirakwiye.
Bitewe n’ubwiza bubi bwa lisansi mu Bushinwa, lisansi irimo sulfur, fosifore na MMT irimo manganese. Ibi bice by’imiti bizakora chemical complexes ku buso bwa sensor ya ogisijeni no mu cyuma gihindura umwuka mu buryo butatu hamwe n’umwuka usohoka nyuma yo gushya. Byongeye kandi, bitewe n’ingeso mbi z’umushoferi zo gutwara imodoka, cyangwa gutwara imodoka igihe kirekire mu mihanda yuzuye, moteri ikunze kuba idashyushye neza, ibyo bikabyara carbon nyinshi muri sensor ya ogisijeni na converter ya catalytic y’uburyo butatu. Byongeye kandi, uduce twinshi tw’igihugu dukoresha lisansi ya etanoli, ifite ubushobozi bwo gusukura cyane, isukura ingano mu cyumba gitwika ariko ntishobora kubora no gutwika, bityo iyo imyuka ihumanya iva mu kirere, iyi myanda izashyirwa no ku buso bwa sensor ya ogisijeni na converter ya catalytic y’uburyo butatu. Biterwa n'ibintu byinshi bituma imodoka imaze kugenda ibirometero byinshi, uretse ubwinshi bwa karubone mu cyuma gitwara abagenzi n'icyumba cyo gutwika, bizanatera ikibazo cyo kunanirwa kwa ogisijeni n'uburozi bwa three-way catalytic converter, kuziba kwa three-way catalytic converter na valve ya EGR ifunzwe n'amazi yafashwe n'ibindi bibazo, bigatera imikorere mibi ya moteri, bigatuma ikoreshwa ry'ibikomoka kuri lisansi ryiyongera, ingufu zigabanuka n'imyuka isohoka irenze urugero n'ibindi bibazo.
Gusana moteri mu buryo busanzwe bigarukira gusa ku kubungabunga sisitemu yo gusiga amavuta, sisitemu yo kwinjira n'iy'ibikomoka kuri lisansi, ariko ntibishobora kuzuza ibisabwa byose byo kubungabunga sisitemu yo gusiga amavuta igezweho, sisitemu yo kwinjira, sisitemu yo gutanga lisansi n'iy'imyuka isohora umwuka, cyane cyane ibisabwa mu kubungabunga sisitemu yo kugenzura imyuka ihumanya. Kubwibyo, nubwo imodoka yaba ikora neza igihe kirekire, biragoye kwirinda ibibazo byavuzwe haruguru.
Mu gusubiza amakosa nk'ayo, ingamba zifatwa n'ibigo bibungabunga ibidukikije ubusanzwe ni ugusimbuza ibikoresho bipima umwuka wa ogisijeni n'ibikoresho bihindura umwuka wa ogisijeni mu buryo butatu. Ariko, kubera ikibazo cy'ikiguzi cyo gusimbuza, amakimbirane hagati y'ibigo bibungabunga ibidukikije n'abakiriya arakomeje. Cyane cyane ayo adashingiye ku gihe cyo gusimbuza ibikoresho bipima umwuka wa ogisijeni n'ibikoresho bihindura umwuka wa ogisijeni mu buryo butatu, akenshi ni yo akunze kuba intandaro y'amakimbirane, abakiriya benshi ndetse bavuga ko ikibazo giterwa n'ubwiza bw'imodoka.
