ʻO ka mea ʻike oxygen (Lambda probe)
Nā mea
ʻO kahi sensor oxygen (OC), ʻike ʻia hoʻi he lambda probe, e ana i ka nui o ka oxygen i loko o nā kinoea hoʻopau ma ka hoʻouna ʻana i kahi hōʻailona i ka ʻāpana hoʻokele engine (ECU).
Aia i hea ka mea ʻike oxygen
Hoʻokomo ʻia ka mea ʻike oxygen mua DK1 i loko o ka exhaust manifold a i ʻole i ka paipu hoʻopau mua ma mua o ka mea hoʻololi catalytic. E like me kāu e ʻike ai, ʻo ka catalytic converter ka ʻāpana nui o ka ʻōnaehana hoʻokuʻu kaʻa.
Hoʻokomo ʻia ka hope lambda probe DK2 i loko o ka exhaust ma hope o ka catalytic converter.
Ma nā ʻenekini 4-cylinder, ua hoʻokomo ʻia ma kahi o ʻelua mau ʻimi lambda. Loaʻa nā ʻenekini V6 a me V8 i ʻehā mau mea ʻike O2.
Hoʻohana ka ECU i ka hōʻailona mai ka sensor oxygen mua e hoʻoponopono i ka hui ʻana o ka ea / wahie ma ka hoʻohui ʻana a hōʻemi paha i ka nui o ka wahie.
Hoʻohana ʻia ka hōʻailona sensor oxygen hope e kāohi i ka hana o ka catalytic converter. I nā kaʻa hou, ma kahi o ka lambda probe mua, hoʻohana ʻia kahi mea ʻike ea-wahie. Hana like, akā me ka pololei.
Pehea e hana ai kahi mea ʻike oxygen
Nui nā ʻano o ka ʻimi lambda, akā no ka maʻalahi, ma kēia ʻatikala mākou e noʻonoʻo wale i nā mea ʻike oxygen maʻamau e hoʻoulu ai i ka volta.
E like me ka manaʻo o ka inoa, hoʻohua ka uila e hoʻohua ai i ka oxygen sensor i kahi liʻiliʻi liʻiliʻi e like me ka ʻokoʻa o ka nui o ka oxygen i loko o ke kinoea hoʻopau a me ke kinoea hoʻopau.
No ka hana kūpono, pono e hoʻomehana ʻia ka probe lambda i kahi mahana. Loaʻa i kahi mea ʻike maʻamau i kēia manawa kahi mea hoʻomehana uila i hoʻohana ʻia e ka ECU mīkini.
Ke wiwi ka huila wahie-ea (FA) e komo ana i ka enekini (ka wahie li'ili'i a me ka nui o ka ea), nui aku ka oxygen i loko o nā kinoea ho'opau, a ho'opuka ka mea 'ike oxygen i ka uila li'ili'i loa (0,1-0,2 V).
Inā waiwai ka wahie (ʻoi aku ka nui o ka wahie a ʻaʻole lawa ka ea), he emi ka oxygen i koe i loko o ka exhaust, no laila e hoʻonui ka mea ʻike i ka uila (e pili ana i 0,9V).
Hoʻoponopono lākiō ea-wahie
ʻO ka mea ʻike oxygen mua ke kuleana no ka mālama ʻana i ka ratio maikaʻi loa o ka ea / wahie no ka ʻenekini, ʻo ia ka mea ma kahi o 14,7:1 a i ʻole 14,7 ʻāpana ea i 1 ʻāpana wahie.
Hoʻoponopono ka ʻāpana hoʻomalu i ke ʻano o ka hui ʻana o ka ea-wahie e pili ana i ka ʻikepili mai ka mea ʻike oxygen mua. Ke ʻike ka ʻimi lambda mua i nā pae oxygen kiʻekiʻe, manaʻo ka ECU e holo wikiwiki ana ka mīkini (ʻaʻole lawa ka wahie) a no laila hoʻohui i ka wahie.
Ke haʻahaʻa ka pae o ka oxygen i loko o ka pauku, manaʻo ka ECU e holo waiwai ana ka mīkini (nui loa ka wahie) a hoʻemi i ka lako wahie.
Ke hoʻomau nei kēia kaʻina hana. Ke hoʻololi mau nei ka lolouila ʻenekini ma waena o nā huila wīwī a waiwai hoʻi no ka mālama ʻana i ka lakio ea/wahie maikaʻi loa. Kapa ʻia kēia kaʻina hana i pani pani ʻia.
Inā ʻoe e nānā i ka hōʻailona puʻupuʻu o ka oxygen sensor mua, aia ia mai ka 0,2 volts (lean) a hiki i ka 0,9 volts (waiwai).
Ke hoʻomaka anuanu ke kaʻa, ʻaʻole wela piha ka sensor oxygen mua a ʻaʻole hoʻohana ka ECU i ka hōʻailona DC1 e hoʻoponopono i ka lawe ʻana i ka wahie. Ua kapa ʻia kēia ʻano hana open loop. Aia wale nō ke hoʻomehana ʻia ka mea ʻike e hele ai ka ʻōnaehana hoʻokele wahie i ke ʻano pani.
I loko o nā kaʻa hou, ma kahi o kahi mea ʻike oxygen maʻamau, ua hoʻokomo ʻia kahi mea ʻike ākea ākea ea-wahie. ʻOkoʻa ka hana ʻana o ka ʻenekini lākiō ea/wahie, akā he kumu like ia: e hoʻoholo inā he waiwai a wīwī paha ka hui ʻana o ka ea/wahie e komo ana i ka ʻenekini.
ʻOi aku ka pololei a hiki ke ana i kahi ākea ākea.
Mīkini uila o hope
Hoʻokomo ʻia ka mea ʻike oxygen hope a i lalo paha i ka pauka ma hope o ka mea hoʻololi catalytic. He ana ia i ka nui o ka oxygen i loko o nā kinoea pau e waiho ana i ka catalyst. Hoʻohana ʻia ka hōʻailona mai ka probe lambda hope e nānā i ka pono o ka mea hoʻololi.
Hoʻohālikelike ka mea hoʻoponopono i nā hōʻailona mai ka mua a me ka hope O2 sensors. Ma muli o nā hōʻailona ʻelua, ʻike ka ECU i ka maikaʻi o ka hana ʻana o ka catalytic converter. Inā hāʻule ka catalytic converter, hoʻohuli ka ECU i ke kukui "Check Engine" e hōʻike iā ʻoe.
Hiki ke nānā ʻia ka sensor oxygen hope me kahi scanner diagnostic, kahi adapter ELM327 me ka polokalamu Torque, a i ʻole kahi oscilloscope.
ʻIke ʻia ʻo Oxygen Sensor
ʻO ka ʻimi lambda mua ma mua o ka mea hoʻololi catalytic i kapa ʻia ʻo ka "upstream" sensor a i ʻole sensor 1.
ʻO ka mea ʻike hope i hoʻokomo ʻia ma hope o ka mea hoʻololi catalytic i kapa ʻia ʻo ka sensor lalo a i ʻole sensor 2.
Hoʻokahi wale nō poloka (bank 4/bank 1). No laila, ma kahi ʻenekini 1-cylinder inline, ʻo ka huaʻōlelo "bank 4 sensor 1" pili wale i ka sensor oxygen mua. "Bank 1 Sensor 1" - hope oxygen sensor.
E heluhelu hou: He aha ka Bank 1, Bank 2, Sensor 1, Sensor 2?
Loaʻa i ka mīkini V6 a i ʻole V8 ʻelua poloka (a i ʻole ʻelua ʻāpana o kēlā "V"). ʻO ka maʻamau, kapa ʻia ka poloka cylinder i loko o ka cylinder #1 ʻo "bank 1".
ʻOkoʻa ka wehewehe ʻana o nā mea hana kaʻa ʻokoʻa i ka Bank 1 a me ka Bank 2. No ka ʻike ʻana i kahi o ka panakō 1 a me ka panakō 2 ma kāu kaʻa, hiki iā ʻoe ke nānā i ka makahiki, hana, hoʻohālike, a me ka nui o ka mīkini ma kāu manual hoʻoponopono a i ʻole Google.
Ke hoʻololi nei i ka mea ʻike oxygen
He mea maʻamau nā pilikia sensor oxygen. Hiki i ka ʻimi lambda hewa ke alakaʻi i ka hoʻonui ʻana i ka wahie, hoʻonui i nā hoʻokuʻu a me nā pilikia kaʻa like ʻole (rpm drop, poor acceleration, rev float, etc.). Inā hemahema ka ʻike oxygen, pono e hoʻololi ʻia.
Ma ka hapanui o nā kaʻa, hoʻololi i ka DC he hana maʻalahi. Inā makemake ʻoe e hoʻololi iā ʻoe iho i ka mea ʻike oxygen, me kahi mākaukau a me kahi manual hoʻoponopono, ʻaʻole ia he paʻakikī, akā pono paha ʻoe i kahi mea hoʻohui kūikawā no ka sensor (kiʻi ʻia).
I kekahi manawa paʻakikī paha ka wehe ʻana i kahi probe lambda kahiko, no ka mea, ʻeleʻele pinepine ia.
ʻO kekahi mea ʻē aʻe e hoʻomanaʻo ʻia, ua ʻike ʻia kekahi mau kaʻa i nā pilikia me nā mea ʻike oxygen hou.
No ka laʻana, aia nā hōʻike o kahi sensor oxygen aftermarket e hoʻopilikia ana i kekahi mau mīkini Chrysler. Inā maopopo ʻole ʻoe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mea ʻike kumu.
