ʻIkepili hope-oxygen

I kēia mau lā, hoʻolako ʻia nā kaʻa me ʻelua mau mea ʻike oxygen, hoʻokahi ma mua o ka catalyst ala ʻekolu a ʻo kekahi ma hope. ʻO ka hana o ke alo ka ʻike ʻana i ka ratio o ka ea-wahie o ka mīkini ma lalo o nā kūlana hana like ʻole, a i ka manawa like, hoʻoponopono ke kamepiula i ka nui o ka wahie a helu i ka manawa hoʻāla e like me kēia hōʻailona. ʻO ka hope ka mea nui e hoʻāʻo i ka hana o ka catalytic converter ʻekolu ala! Ie ka hoohuli ana o ka catalyst. He kumu koʻikoʻi ia e hoʻāʻo ai inā hana maʻamau ka catalyst ala ʻekolu (maikaʻi a maikaʻi ʻole paha) ma ka hoʻohālikelike ʻana me ka ʻikepili o ka sensor oxygen mua.

Hoʻohana ka mea ʻike oxygen i ke kumu Nernst.

ʻO kāna mea nui he paipu ceramic ZrO2 porous, he electrolyte paʻa, a ua hoʻopaʻa ʻia kona mau ʻaoʻao ʻelua me nā electrodes Pt porous. Ma kekahi mahana, ma muli o ka ʻokoʻa o ka oxygen ma nā ʻaoʻao ʻelua, ua hoʻopili ʻia nā molekole oxygen ma ka ʻaoʻao kiʻekiʻe (i loko o 4 o ka pahu ceramic) ma ka electrode platinum a hui pū ʻia me nā electrons (4e) e hana i nā ion oxygen O2- , ka mea e hana i ka electrode hoʻopiʻi maikaʻi, a O2- ions neʻe i ka haʻahaʻa-oxygen kaʻaoʻao kuʻina (exhaust kinoea aoao) ma o ka oxygen ion hakahaka i loko o ka electrolyte, e hana i ka electrode hoʻopiʻi ʻino, ʻo ia hoʻi, hoʻokumu ʻia kahi ʻokoʻa.

Ke haʻahaʻa ka lakio ea-wahie (hui waiwai), emi ka oxygen i loko o ke kinoea hoʻopau, no laila he liʻiliʻi nā ion oxygen ma waho o ka paipu ceramic, e hana ana i ka ikaika electromotive ma kahi o 1.0V;

Ke like ka lakio ea-wahie me 14.7, ʻo ka ikaika electromotive i hana ʻia ma nā ʻaoʻao o loko a me waho o ka paipu ceramic he 0.4V ~ 0.5V, ʻo ia ka mana electromotive kuhikuhi;

Ke kiʻekiʻe ka lākiō ea-wahie (lean hui), kiʻekiʻe ka ʻike o ka oxygen i loko o ke kinoea hoʻopau, a ʻo ka ʻokoʻa o ka ʻokoʻa o ka oxygen i loko a ma waho o ka pahu ceramic he liʻiliʻi, no laila ua haʻahaʻa loa ka ikaika electromotive a kokoke i ka ʻole. .

ʻO ka mea ʻike oxygen wela:

-Heated oxygen sensor he ikaika ke alakaʻi kū'ē;

-ʻAʻole ia e hilinaʻi i ka mahana wela, a hiki ke hana e like me ka mea maʻamau ma lalo o ka haʻahaʻa haʻahaʻa a me ka wela haʻahaʻa haʻahaʻa;

-E komo koke i ka mana pani pani ma hope o ka hoʻomaka.
