Cov tsheb fais fab puas muaj catalytic converters?

Hauv tsab xov xwm no, peb tshawb xyuas seb EVs puas muaj catalytic converters thiab seb lawv puas xav tau.

Catalytic converters yog muaj nyob rau hauv roj av powered tsheb los txo lub tsheb emissions. Txawm li cas los xij, lub tsheb fais fab tsis siv roj av, yog li lawv puas tseem xav tau? Cov lus nug zoo li no tuaj yeem nug thaum piv cov tsheb hluav taws xob (EV) nrog cov roj av.

Cov lus teb yog tsis muaj, piv txwv li tsis muaj catalytic converters nyob rau hauv hluav taws xob tsheb. Qhov laj thawj yog tias lawv tsis xav tau lawv. Tab sis vim li cas ho tsis?

Cov tsheb fais fab puas muaj lub catalytic converter?

Cov lus nug tseem ceeb uas tsab xov xwm no hais txog yog seb lub tsheb fais fab puas muaj lub catalytic converter. Cov lus teb tsis yog, vim hais tias cov tsheb fais fab tsis muaj catalytic converters.

Hybrid tsheb yog ib qho kev zam tsuas yog vim tias lawv tsis muaj hluav taws xob tag nrho thiab muaj lub tshuab hluav taws xob sab hauv. Txawm li cas los xij, peb yuav ua tib zoo saib vim li cas lawv tsis ua, thiab qhov tshwm sim ntawm qhov tsis muaj cov hloov pauv catalytic. Ua ntej, peb yuav tsum paub tias lub catalytic converter ua li cas.

Nco ntsoov: Txawm hais tias tsab xov xwm no yog hais txog cov tsheb fais fab, cov lus nug ntawm seb puas xav tau lub catalytic converter thiab lwm yam ntaub ntawv hais txog lawv siv sib npaug rau cov tsheb fais fab feem ntau.

Catalytic converters ua dab tsi

Lub catalytic converter yog ib qho cuab yeej uas pab txo cov pa phem los ntawm lub cav tsheb. Nws tau ntxiv rau lub tsheb cov yeeb nkab uas yog ib feem ntawm nws qhov tso pa tawm. Nws sab nrauv muaj cov catalyst uas hloov cov pa roj los ntawm lub cav (CO-HC-NOx) mus rau cov roj uas muaj kev nyab xeeb dua (CO₂-H₂ON₂), uas ces muab pov rau saum huab cua (saib daim duab hauv qab no). [2]

Cov roj uas tsim los ntawm lub cav yog hydrocarbons, oxides ntawm nitrogen thiab carbon monoxide. Kev ua haujlwm ntawm catalytic converter yog qhov tseem ceeb vim tias carbon monoxide yog tshuaj lom. Cov qe ntshav liab nqus cov pa no thiab tiv thaiv kom tsis txhob nqus cov pa oxygen xav tau los txhawb txoj sia. [3]

Nyob rau hauv luv luv, nws lub hom phiaj yog ua kom lub tsheb emissions tsawg teeb meem rau peb noj qab haus huv thiab ib puag ncig. Cov pa hluav taws xob kawg (tom qab catalysis) yog carbon dioxide, dej thiab nitrogen. Cov pa roj carbon dioxide kuj tsis muaj teeb meem, tab sis tsawg dua li carbon monoxide.

Kev cai lij choj

Muaj lub catalytic converter hauv lub tsheb yog qhov yuav tsum tau muaj kev cai lij choj yog tias lub tsheb tau nruab nrog lub cav combustion sab hauv. Qhov yuav tsum tau kuaj xyuas thaum kuaj emissions kom paub tseeb tias nws nyob thiab ua haujlwm zoo.

Yuav tsum siv lub catalytic converter tau pib siv rau xyoo 1972 los tswj huab cua thiab dej hauv av los ntawm lub tsheb. Ob peb lub ntsiab lus tseem ceeb ntxiv txog catalytic converters: [4]

• Nws yog txhaum cai los hloov kho, lov tes taw lossis tshem tawm lub catalytic converter ntawm lub tsheb.
• Thaum hloov cov catalytic converter, qhov hloov yuav tsum zoo sib xws.
• Yuav tsum tau kuaj xyuas emissions txhua xyoo.

Ntxiv nrog rau cov tsheb fais fab, tsheb off-txoj kev kuj raug zam los ntawm qhov yuav tsum tau muaj lub catalytic converter.

Vim li cas lub tsheb hluav taws xob tsis xav tau Catalytic Converters

Txij li thaum lub catalytic converter ua hauj lwm los tshem tawm cov pa phem los ntawm lub tsheb lub tsheb combustion engine, thiab hluav taws xob tsheb tsis muaj ib tug internal combustion engine, lawv tsis emission pa gases. Yog li ntawd, hluav taws xob tsheb tsis xav tau ib tug catalytic converter.

Lwm yam hluav taws xob tsheb tsis muaj

Muaj ob peb yam EVs tsis muaj, uas piav qhia vim li cas lawv tsis xav tau lub tshuab hloov pauv catalytic. Ntawm lawv:

• Tsis muaj combustion engine
• Tsis xav tau cov roj cav los lubricate lub cav
• Tsis muaj kev tsim cov kuab tshuaj lom
• Ntau yam khoom siv tsawg dua

Qhov tshwm sim ntawm tsis muaj lub catalytic converter

Kev noj qab haus huv thiab ib puag ncig

Qhov tsis muaj qhov hloov pauv catalytic, vim tias lub tsheb hluav taws xob tsis tso pa tawm, ua rau lawv muaj kev nyab xeeb ntau dua li cov tsheb uas ua, yam tsawg kawg ntawm cov pa phem.

Tus neeg saib xyuas kev ruaj ntseg

Muaj lwm qhov laj thawj yog vim li cas qhov tsis muaj lub catalytic converter ua rau lub tsheb hluav taws xob muaj kev nyab xeeb dua. Qhov no yog kev ruaj ntseg ntawm kev ruaj ntseg. Catalytic converters muaj cov hlau kim xws li platinum, palladium thiab rhodium. Lawv pab nyob rau hauv cov txheej txheem pom kom txo tau cov teeb meem emissions nrog kev pab los ntawm ib tug honeycomb qauv. Lawv catalyze teeb meem gases, li no lub npe catalytic converter.

Txawm li cas los xij, kev saib xyuas kim ua rau catalytic converters lub hom phiaj rau tub sab. Yog tias lub catalytic converter yooj yim tshem tawm, nws ua rau nws lub hom phiaj zoo nkauj dua. Qee lub tsheb txawm muaj ntau tshaj li ib lub catalytic converter.

Yav tom ntej trend

Muab qhov kev xav tau loj hlob ntawm kev thov rau cov tsheb hluav taws xob raws li kev hloov pauv rau lub cav hluav taws xob, kev thov rau catalytic converters yuav poob qis.

Qhov kev ntshaw tiag tiag yog tsim kom muaj ib puag ncig huv. Cov tsheb hluav taws xob muaj lub sijhawm los tswj hwm qhov chaw huv thiab noj qab haus huv los ntawm kev ua cov tsheb uas tsis muaj cov pa phem, uas tshem tawm qhov xav tau ntawm cov catalytic converters.

Nws yuav zoo li tias nyob rau hauv ob peb xyoos, catalytic converters yuav yog ib tug relic ntawm ib tug bygone era ntawm lub tsheb emitting gases.

Kev tswj cov pa phem nrog lub tsheb hluav taws xob

Yog tias lub tsheb fais fab (EVs) tsis tso cov pa phem thiab yog li tsis xav tau lub tshuab hloov pauv catalytic, yog vim li cas peb tseem yuav tsum tswj cov pa phem? Yog vim li cas rau qhov no yog tias, txawm hais tias lub tsheb fais fab lawv tus kheej tsis tso cov pa phem, qhov xwm txheej hloov thaum lub sijhawm tsim khoom thiab them nyiaj.

Cov tuam txhab tsheb fais fab tso tawm ntau cov pa roj carbon dioxide (CO₂) emissions rau lub tsev hluav taws xob tsheb, thiab them cov tes hauj lwm rau them hluav taws xob tsheb kuj tseem vam khom rau cov khoom siv hluav taws xob tsis txuas ntxiv. Yog li ntawd, qhov tseeb hais tias lub tsheb fais fab tsis xav tau catalytic converters tsis tau txhais hais tias peb tau tag nrho dim ntawm qhov xav tau los tswj cov pa phem.

Summing txog

Peb tau tshawb xyuas seb lub tsheb fais fab puas muaj lub catalytic converter. Peb tau qhia tias lawv tsis xav tau, thiab tom qab ntawd peb piav qhia vim li cas lawv tsis xav tau. Yog vim li cas cov tsheb hluav taws xob tsis muaj thiab tsis xav tau lub tshuab hloov pauv catalytic yog tias lawv tsis tsim cov pa phem xws li cov tsheb nrog cov roj av sib xyaw ua ke.

Cov pa phem tseem ceeb yog carbon monoxide. Lub catalytic converter converts qhov no thiab lwm yam kev koom tes gases (hydrocarbons thiab oxides ntawm nitrogen) mus rau hauv lub kuj muaj kev nyab xeeb carbon dioxide, ntxiv rau dej thiab nitrogen.

Qhov teeb meem carbon monoxide ntau dua yuav tsum tau ua haujlwm catalytic converter. Txij li cov tsheb hluav taws xob tsis tso cov pa phem, tsis muaj kev cai lij choj.

Txawm li cas los xij, peb kuj tau qhia tias thaum lub tsheb fais fab yuav zoo li muaj kev nyab xeeb dua rau peb txoj kev noj qab haus huv thiab ib puag ncig, cov pa roj carbon dioxide emissions thaum lawv tsim khoom thiab them nyiaj rau lawv tseem xav tau kev tswj cov pa phem.

Txawm li cas los xij, vim tias kev siv tsheb fais fab yuav nce ntxiv rau yav tom ntej, qhov no txhais tau hais tias qhov kev thov rau catalytic converters yuav poob mus ntxiv.

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.

• Nws siv pes tsawg amps los them lub tsheb fais fab
• multimeter test tso zis
• Dab tsi yog VSR xyaum
