ʻO ke kumu hana o ka catalytic converter ʻekolu ala: i ka wā e hoʻopau ai ka wela kiʻekiʻe o ke kaʻa ma o ka mea hoʻomaʻemaʻe, e hoʻomaikaʻi ka mea hoʻomaʻemaʻe i ka ʻekolu ala catalytic converter i ka hana o nā ʻano ʻekolu o ke kinoea CO, hydrocarbons a me NOx, e hoʻoikaika ai i kāna oxidation - hoʻemi i ka hopena kemika, kahi e lilo ai ka CO oxidation ma ke kiʻekiʻe i carbon dioxide, non-toxic; Hoʻoheʻe ʻia nā hydrocarbons i ka wai (H2O) a me carbon dioxide ma nā wela kiʻekiʻe; Hoʻemi ʻia ka NOx i ka nitrogen a me ka oxygen. ʻEkolu ʻano kinoea ʻino i loko o ke kinoea kino ʻole, i hiki ke hoʻomaʻemaʻe ʻia ka pauka kaʻa. Ke manaʻo nei aia ka loaʻa ʻana o ka oxygen, kūpono ka ratio ea-wahie.
Ma muli o ka maikaʻi ʻole o ka wahie ma Kina, aia ka sulfur, phosphorus a me ka MMT antiknock agent he manganese. ʻO kēia mau mea kemika e hana i nā mea paʻakikī ma luna o ka ʻili o ka mea ʻike oxygen a i loko o ka mea hoʻololi catalytic ʻekolu me ka hoʻokuʻu ʻia ʻana o ke kinoea ma hope o ka puhi ʻana. Eia kekahi, ma muli o nā hana hoʻokele maikaʻi ʻole o ka mea hoʻokele, a i ʻole ka lōʻihi o ke kaʻa ʻana ma nā alanui congested, pinepine ka mīkini i kahi kūlana hoʻopau ʻole, kahi e hoʻohui ai i ke kalapona i loko o ka oxygen sensor a me ʻekolu ala catalytic converter. Eia kekahi, he nui nā wahi o ka ʻāina e hoʻohana i ka ethanol gasoline, he ikaika ka hoʻomaʻemaʻe ʻana, e hoʻomaʻemaʻe i ka unahi i loko o ke keʻena kuni akā ʻaʻole hiki ke decompose a puhi, no laila me ka hoʻokuʻu ʻia ʻana o ke kinoea ʻōpala, e waiho pū ʻia kēia mau lepo ma luna o ka ʻili o ka sensor oxygen a me ka catalytic converter ʻekolu. Ma muli o nā kumu he nui e hana ai ke kaʻa ma hope o ke kaʻa ʻana no kahi mau mile, me ka hoʻohui ʻana i ke kalapona i loko o ka valve intake a me ke keʻena puhi ahi, e hoʻokau pū ʻia ka sensor oxygen a me nā ala ʻekolu catalytic converter poisoning failure, ʻekolu ala catalytic converter blockage a me EGR valve i hoʻopaʻa ʻia e ka sediment paʻa a me nā hemahema ʻē aʻe, ka hopena o ka hoʻonui ʻana i ka hana o ka mīkini.
ʻO ka mālama maʻamau o ka mīkini kuʻuna i kaupalena ʻia i ka mālama kumu o ka ʻōnaehana lubrication, ʻōnaehana intake a me ka ʻōnaehana hoʻolako wahie, akā ʻaʻole hiki ke hoʻokō i nā koi o ka mālama piha ʻana o ka ʻōnaehana lubrication mīkini hou, ʻōnaehana intake, ʻōnaehana lako wahie a me nā ʻōnaehana exhaust, ʻoi aku ka pono o ka mālama ʻana o ka ʻōnaehana hoʻokuʻu.

I ka pane ʻana i ia mau hewa, ʻo nā hana i hana ʻia e nā ʻoihana mālama e hoʻololi i nā mea ʻike oxygen a me nā mea hoʻololi catalytic ʻekolu.
