Ihinduranya rya catalitiki nigikoresho cyingenzi cyo kweza hanze cyashyizwe muri sisitemu yo kuzimya, gishobora guhindura imyuka yangiza nka CO, HC na NOx ivuye muri gaze isohoka ikabamo dioxyde de carbone itagira ingaruka, amazi na azote binyuze muri okiside no kugabanya.Iyo gazi yubushyuhe bwo hejuru yubushyuhe inyuze murwego rwo kweza, umukozi woza muri catalizator azamura ibikorwa bya CO, HC na NOx kandi abateze imbere gukora imiti igabanya ubukana bwa okiside, aho CO iba okiside itagira ibara kandi gaze ya gaze karuboni idafite ubumara ku bushyuhe bwinshi;Ibicuruzwa bya HC bihindurwamo amazi (H20) na dioxyde de carbone ku bushyuhe bwinshi;NOx yagabanutse kuri azote na ogisijeni.Imyuka itatu yangiza ihinduka imyuka itagira ingaruka, kugirango gaze umurizo isukure.

Igice cyabatwara igice cya catalizator nigice cyibikoresho bya ceramic, byashyizwe mumiyoboro idasanzwe.Yitwa umwikorezi kuko ititabira reaction ya catalitiki, ahubwo itwikiriwe na platine, rhodium, palladium nibindi byuma byagaciro.Irashobora guhindura HC na CO muri gaze yuzuye mumazi na CO2, ikabora NOx muri azote na ogisijeni.HC na CO ni imyuka yubumara.Guhumeka cyane bizaganisha ku rupfu, mugihe NOX izahita itera umwotsi wa fotokome.

Mugihe cyimikorere isanzwe ya catalitike ihindura, kubera ubwinshi bwubushyuhe bwa reaction buterwa na okiside reaction, imikorere ya catalitike ihindura irashobora kugenzurwa no kugereranya itandukaniro ryubushyuhe.Ubushyuhe bwo gusohoka bwa catalitike ihindura igomba kuba byibuze 10 ~ 15% kurenza ubushyuhe bwinjira.Kubisanzwe bisanzwe bya catalitiki ihindura, ubushyuhe bwo gusohoka bwa catalitike ihindura igomba kuba hejuru ya 20 ~ 25% kurenza ubushyuhe bwinjira.

Icyuma cya Honeycomb cataliste cataliste ifite ibyiza byo gutwika vuba, ingano ntoya, imbaraga za mashini nyinshi, imbaraga zirwanya ubushyuhe, nibindi. Ikoreshwa cyane mumapikipiki no mumodoka (moteri ya lisansi na moteri ya mazutu).Turashobora kuzuza ibyuka bihumanya Euro II, Euro III, Euro IV, Euro V, EPA na CARB.
