Ke loiloi i ke kūlana ʻenehana o ke kaʻa i kūʻai ʻia, poina pinepine mākou e nānā i ka hana o ka catalytic converter. I kēia manawa, nui nā mea kūʻai hewa ʻole e hāʻawi ana i nā kaʻa me nā mea hoʻololi catalytic pōʻino a i ʻole.

Ke loiloi i ke kūlana ʻenehana o ke kaʻa i kūʻai ʻia, poina pinepine mākou e nānā i ka hana o ka catalytic converter. I kēia manawa, nui nā mea kūʻai hewa ʻole e hāʻawi ana i nā kaʻa me nā mea hoʻololi catalytic pōʻino a i ʻole. Inā i ka wā o ka ʻike loea o ke kaʻa e ʻike ʻia he hemahema kēia mea hana, ʻaʻole ʻae ʻia ke kaʻa e hana.

ʻAʻohe diagnostics piha o ke kūlana o ka catalyst hiki iā mākou iho, pono mākou e hoʻohana e nā mechanics kūpono. Kiʻi na Robert Quiatek

ʻO ka catalyst kahi mea kaʻa, ʻo ke ʻano o ia mea paʻakikī ke ʻike iā ʻoe iho. He mea paʻakikī ke ʻike ʻia, aia ma lalo o ke kaʻa, hūnā maʻamau ma hope o ke kino. Eia nō naʻe, i ke kūʻai ʻana i kahi kaʻa i hoʻohana ʻia, pono e lawe i kekahi manawa e nānā i kēia mea o ke kaʻa, no ka mea he mea maʻamau ke kumukūʻai no ka hoʻoponopono ʻana. ʻO ka hana mua paha e nānā inā hoʻokomo maoli ʻia ka catalytic converter i loko o ke kaʻa. Eia naʻe, pono ʻoe e komo i loko o ke kahawai e hana ai. Aia ma kekahi mau kaʻa e hoʻokomo ʻia kahi ʻāpana o ka paipu ma kahi o ka catalytic converter. ʻAʻole pono ʻoe e lilo i mechanic akamai e ʻike i kahi "hoʻololi" i ka maka. ʻO kaʻoiaʻiʻo, ʻo ka nele o kahi catalyst ʻaʻole ia e kāpae i ka hiki ʻana o kāna hui ma hope, akā pono mākou e noʻonoʻo i nā kumukūʻai, ʻo ia ka mea maʻamau mai kahi mau haneli a ʻoi aku ma mua o 2 zł.

E nānā i ke kūlana o ka catalytic converter!

Mana pono

ʻIke maʻalahi ka pōʻino Catalyst ma ke ana ʻana i ke kiʻekiʻe o ka ʻawaʻawa, wehewehe ʻo Wojciech Kulesza, kahi mea loiloi PZMot laikini. - ʻIke pinepine ʻia nā hōʻailona o kona hiki ʻole i ka wā e hana ai ke kaʻa. ʻO ka pau ʻana o ka mana, ka walaʻau ʻana o ka ʻenekini nui, a i ʻole nā ​​​​pilikia hoʻomaka ʻana he hōʻailona ia ʻaʻole holo pono ka catalytic converter.

No ka hana pono ʻana, koi ʻia kahi ʻano i wehewehe ʻia o ka hui ʻana o ka wahie-ea. ʻO ka lakio maikaʻi loa o ka ea me ka ʻaila he 14,75:1. ʻO nā mea hoʻoheheʻe i hoʻopaʻa ʻia e ka lolouila wale nō e hiki ke hāʻawi i nā ʻano kikoʻī i ana ʻia o ka hui ʻana, no laila ʻoi aku ka maikaʻi o nā catalysts no nā kaʻa i lako i ka wahie ma mua o ka carburetor. Hana ʻia kekahi hana koʻikoʻi e ka lambda probe i loko o ka ʻōnaehana hoʻopau ma hope o ka catalyst. Hoʻopili ia i ke ʻano o nā kinoea hoʻopau a hoʻouna i nā hōʻailona i ke kamepiula hoʻokele injection. Inā pōʻino ka catalytic converter, paʻakikī ke ʻike me ka maka ʻōlohelohe. Eia nō naʻe, ʻo ka hoʻomalu ʻana i nā kinoea hoʻopau e puka mai ana mai ka paipu hoʻopau e haʻi nui iā mākou. ʻO ka mea nui loa ka pākēneka o carbon monoxide (CO) i loko o nā kinoea hoʻopau. I loko o kahi kaʻa me ka ʻole o ka catalytic converter a i ʻole me ka catalyst pohō, aia ia mai ka 1,5 a hiki i ka 4 pakeneka. ʻO kahi catalyst maikaʻi e hoʻemi i kēia lakio ma kahi o 0,03% a i ʻole haʻahaʻa iki.

ʻO ka maʻiʻo o nā pūhui ʻē aʻe (nitrogen oxides, hydrocarbons a me carbon dioxide) kahi hopena o ka nui o CO. ʻO ka nānā ʻana ma ke kahua diagnostic e hōʻike i nā hewa i ʻike ʻia, a e ʻike ka maka i hoʻomaʻamaʻa ʻia o ka mechanic i kahi pōʻino mechanical.

"I ke kūʻai ʻana i kahi kaʻa i hoʻohana ʻia, pono nō hoʻi e nīnau i ka mea kūʻai aku inā ua hoʻololi ʻia nā mea hana ma mua," wahi a Wojciech Kulesza, kahi mea loiloi PZMot laikini. - ʻOi aku ka lōʻihi o nā catalysts hou, akā ʻoi aku ka nui o nā mea hana e hoʻololi iā lākou ma hope o 120-150 tausani mau kilomita. ʻOiaʻiʻo, hiki i nā catalysts ke lōʻihi a hiki i 250 mau kilomita me ka ʻole, akā i ka wā e hoʻoholo ai e kūʻai i kahi kaʻa me ka mile mile kiʻekiʻe ma ka mika, pono e noʻonoʻo kekahi e pono ke hoʻololi koke ʻia ka catalyst ma muli o ke kapa.

Nā rula pili nui

E akahele me ka wahie - ʻo ka liʻiliʻi loa o ka ʻaila alakaʻi hiki ke hoʻopau mau i ka catalytic converter. He mea maʻalahi ke hana hewa, ʻoiai ke hoʻopiha ʻoe i ka pahu.

Mai ho'āʻo e hoʻomaka i ke kaʻa me ke ʻano "haʻaheo".

E ho'āʻo e hoʻohana i nā keʻena kinoea i hōʻoia ʻia kahi maikaʻi o ka wahie. ʻO ka wahie haumia a haʻahaʻa haʻahaʻa e alakaʻi i ka hoʻoheheʻe ʻana o ka catalytic liner ma muli o ke kiʻekiʻe o ka hana ʻana. ʻO ka mahana hana kūpono no ka catalyst ma kahi o 600°C, me ka wahie haumia hiki ke hiki i 900°C.

E nānā mau i ke ʻano o nā ʻūhā. ʻO ka loaʻa ʻole o kahi huna ahi i loko o kekahi o nā cylinders e alakaʻi i ka ʻaila unburned e komo i ka ʻōnaehana exhaust, e hoʻoheheʻe i ka catalyst.

Hiki ke hōʻino ʻia inā kuʻi ʻo ia i ka pōhaku, ka pā, etc.

ʻAʻole hiki ke hoʻomaloʻo koke i ka catalyst, e hana ana, no ka laʻana, i ka wā e holo ai i loko o kahi puddle hohonu.

E nānā ma mua o kou kūʻai ʻana

ʻO Wojciech Kulesza, ka mea loiloi PZMot laikini

- Ma mua o ke kūʻai ʻana i kaʻa i hoʻohana ʻia, pono e nānā i ke ʻano o ka paipu hoʻopau. Inā he lepo loa a uhi ʻia paha i ka ʻehu, he hōʻailona ʻoiaʻiʻo kēia o ka hemahema o ka ʻōnaehana hoʻopau, ʻoi aku ka catalytic converter. He mea maʻalahi hoʻi ke nānā inā ua hoʻololi ʻia ka catalytic converter i kēia manawa, akā pono kēia i ke kaʻa e hele i ke kahawai. E huki nā mea hana hou i ka manaʻo me kona helehelena hou a me ka pepa metala ʻālohilohi, no laila ua maʻalahi ke hoʻohālikelike i nā hōʻoia a ka mea kūʻai aku me ka ʻoiaʻiʻo. E nānā pū mākou i ka catalyst no nā hōʻailona o ka pōʻino mechanical. ʻO nā māhā a i ʻole nā ​​piko paha e hōʻike ana ua paʻi ʻia, a pohā paha kāna mea hoʻokomo keramika.
