Catalyst: yog dab tsi? Vim li cas peb yuav tsum tau ib lub hauv paus ntawm lub tsheb?

Muaj yog ib feem niaj hnub tsheb, uas tau ntau xyoo yog ib tug ua heev rhuab battles tsav tsheb. Tab sis nyob rau hauv cov kev tsis sib haum yog yooj yim to taub cov nqe lus ntawm txhua sab. Ib tug ntawm cov neeg tsav tsheb "rau" thiab ib tug "tawm tsam". Qhov no kom meej - lub catalytic converter. Vim li cas peb yuav tsum tau ib lub hauv paus uas yog ib qho tseem ceeb, nws ua nyob rau hauv lub tsim ntawm lub tsheb, vim li cas hais lus cam txog nws mus ib txhis? Wb sim kom paub tseeb.

catalytic converter

Qhov no yog ib feem yog yus muaj los ntawm tej yam yooj yim tsim, tab sis lub luag hauj lwm nws plays nyob rau hauv lub tsheb, ib tug heev loj thiab loj heev. Lub lag luam ntawm tej internal combustion engine nrog emission ntawm ib tug plurality ntawm sib txawv heev thiab heev teeb meem tshuaj (tag nrho cov ntawm cov tshuaj thiab nkev kuab lom tog los ntawm ib tug tso zis txoj kev ntawm lub tsheb yog muaj ncaj qha mus rau qhov chaw). Converter yuav txo tau cov tshuaj muaj taug ntawm emissions, li no kev txhim kho cov ib puag ncig qhov teeb meem no.

Yog li, los ntawm txoj kev tshwj xeeb tshuaj haum, tshwj xeeb yog tej yam tshuaj lom, yog tsis zoo tshaj plaws cawv rau cov cua, hloov dua siab tshiab rau hauv tsawg nkev kuab lom tog uas yog ces tso zis los ntawm lub tso yeeb nkab.

Nyob rau hauv tas li ntawd tso catalyst system kuj ntiav oxygen sensors. Lawv tswj qhov zoo ntawm cov combustible sib tov thiab muaj feem xyuam rau lub lag luam ntawm lub catalytic converter. Nrhiav cov khoom no yuav ua tau nyob rau hauv lub tso huam ntawm lub yam khoom uas kom lub tsheb tsis nrov thiab engine. Lub apparatus yog ntxiv kev tiv thaiv los ntawm ib tug hlau screen, vim hais tias thaum lub ntaus ntawv yog rhuab. Saib, nws zoo li ib lub hauv paus - ib tug yees duab ntawm nws coj hauv qab no.

Keeb kwm ntawm creation

Nyob rau hauv lub 60 xyoo nyob rau hauv tsoom fwv ntawm tag nrho cov teb chaws uas tsim ntawm lub ntiaj teb no mloog rau cov ib puag ncig theem, thiab kawm rau tus nqi ntawm emissions los ntawm lub tso kav ntawm ntau lub tsheb. Thiab nws yuav tsum tau hais tias tus kev cai lij choj thaum emission ntau ntau yuav tsis raug tom.

Nyob rau hauv 1970, tus thawj heev qauv uas tau txais, uas tau coj mus rau cov xim ntawm kev tswj lub tsheb kev txhawj xeeb. Cov qauv no tau hais ib daim ntawv teev cov txheej txheem rau cov ntsiab lus thiab kom muaj nuj nqis ntawm tshuaj lom tso gases tshwj xeeb teeb meem tshuaj.

Qhov no tus txheej txheem yog qhia hais tias nyob rau hauv tsheb tshiab yog yuav tsum tau siv ib lub hauv paus hais tias xws li ib tug ntaus ntawv yuav zoo heev txo tus nqi ntawm cov pa roj carbon monoxide thiab hydrocarbon combustion khoom.

Txij li thaum 1975, lub catalyst pib equip txhua lub tsheb uas ua. Cov khoom no yog yuav tsum tau.

Tus ntaus ntawv thiab hauv paus ntsiab lus ntawm cov lag luam

Feem ntau qhov no ntaus ntawv yog muab tom qab cov qhov tso zis yeeb nkab ntawm lub cav los yog tej zaum nws yuav yuav mounted ncaj qha rau ntawm flange ntawm lub tso manifold.

Apparatus muaj ib tug tshwj xeeb cov cab kuj unit, ib tug hlau vaj tse nyob thiab insulating cov ntaub ntawv.

Cov cab kuj muaj ib tug plurality ntawm hlwb, xws li ib tug honeycomb. Nws ua rau tus ntaus ntawv yuav luag tag nrho cov ua hauj lwm. Cov hlwb muaj kev tshwj xeeb txheej - ua hauj lwm muaj pes tsawg leeg. Interestingly, lub zoo-nyeem kev nthuav dav ntawm kev ua hauj lwm tam sim ntawd, tab sis tsuas yog tom qab qhov kub thiab txias nyob rau hauv lub tso system ntawm lub nce mus 200-300 degrees.

Neutralizer afterburning ntawm cov pa roj carbon monoxide muaj nyob rau hauv lub combustion khoom raws li hydrocarbons. Nws tseem muaj lwm yam uas neutralize lub catalyst. Yuav ua li cas yog cov tshuaj? Qhov no Nox. Cov pa roj no mas lom thiab teeb meem. Nws txav lub tib neeg txheej membrane.

Cell-converters them los ntawm ib tug heev nyias zaj duab xis nyob rau hauv lub hauv paus ntawm lub cim platinum-iridium hlau. Cov seem ntawm tej yam tshuaj lom uas tsis hlawv nyob rau hauv lub cav, thaum kov ib tug kub nto, me me hlwb instantly hlawv. Rau tus txheej txheem no, tus catalyst yuav siv sij hawm cov pa residue uas tseem yog twb lom tso roj cua. Raws li ib tug tshwm sim ntawm no yog ib feem ntawm lub tso yeeb nkab nyob tsis tej yam tshuaj lom.

hom

Catalyst Cartridges yuav ua los ntawm tej hub ntaub ntawv los yog los ntawm cov hlau. Cov neeg tsav tsheb yog ntau heev thiab nrov nws yog tais diav ntim chaws. Lawv yog cov zoo mas siab kub, thiab yog tsis cuam tshuam los ntawm corrosion. Cov qhov zoo - tsis muaj nqi rau xws li ib tug catalyst (ib yam khoom uas, ib yam li ceramics, muaj ib tug tsis tshua muaj ntau lawm nqi, paub lub tshwj xeeb).

Nws muaj ib tug tej hub catalyst thiab cons. Qhov no yog nws cov fragility. Nthuav dav lig resistant mus rau ntau yam hom ntawm cov neeg kho tshuab kev puas tsuaj, raws li zoo raws li lub ntaus ntawv yog nyob rau hauv lub qab ntawm lub tshuab, muaj yog ib tug zoo lub caij nyoog lub tsev ntawm lub rooj sib tham nrog ib tug ciam teb, ib lub pob zeb, dab tsi. Ces qhov khoom yuav lov. Analogs ntawm cov hlau yog zog npaum li cas, tab sis lawv cov nqi yog heev vim hais tias ntawm lub platinum hlau. Piv txwv li, Vaz catalyst nyob rau hauv cov kev tshwm sim ntawm ib tug rhuav tshem yog tsis kho, thiab tshiab, muaj ntau yam tsis yuav vim hais tias ntawm tus nqi.

Catalysts rau ntau hom ntawm lub tsheb

Tsheb, nyob ntawm seb koj chaw tsim tshuaj paus yuav txawv ho. Tib yam siv rau lub converters. Lawv kuj txawv los ntawm cov qauv qauv. Peb yuav saib cov feem ntau nrov tsheb hom.

WHA

Lub catalyst rau lub vases yog tsis sib txawv. Lawv muaj tag nrho cov uas ua los ntawm cov hlau, feem ntau tsis vim muaj ntau yam kev raug mob. Nrhiav tus ntaus ntawv nyob rau hauv lub tsheb yuav ua tau nyob rau hauv lub hauv qab, nyob rau hauv lub cheeb tsam ntawm lub tso yeeb nkab ntawm lub cav. Feem ntau nyob rau hauv cov ntaub ntawv kho yog tsis tau catalyst tsis.

"Ford"

Nyob rau hauv sib piv rau lub domestic automakers, lub tuam txhab "Ford" muab kev kho mob ntawm tus tsav tsheb. Yog li, ib tug apparatus rau neutralizing nkev kuab lom tog nyob rau hauv cov cav tov ntawm no cim yog ua lub hauv paus ntawm ceramics.

Yuav kom tswj cov nyiaj ntawm cov pa dua qhov zoo tshuaj cov tshuaj tiv thaiv ntaus ntawv siv nyob rau hauv ib tug lambda sojntsuam uas yog kev nyob rau hauv lub computer.

Yog li, Catalyst "kom pom tseeb" yog ib tug hluas catalyst thiab ob collector sensors. Nrog haib xyaw khiav ob collector thiab 4 sensors. Qhov kawg yuav pom ua ntej thiab tom qab lub tsev. converter yuav tau saib nrog rau cov dashboard.

Tus ntaus ntawv yog tsim los rau 120 txhiab. Km. Yog hais tias koj siv ib tug tsawg-zoo lub cev muaj zog roj, qhov no yog ib feem yuav puas sai sai. Thaum ua hauj lwm ntawm lub kho catalyst "Ford" yog tsis yooj yim sua. Nyob rau hauv cov ntaub ntawv no, tsuas hloov.

Check lag luam yuav ua tau yooj yim, thiab to taub zoo li cas yuav tsum tau hloov, thiab yooj yim. Nrog rau cov catalyst inoperative hwj chim cov yam ntxwv ntog tshuam. Yuav kom ntsuam xyuas cov ntaus ntawv, ua ntsuas ntawm teeb meem tshuaj nyob rau hauv lub tso ntawm lub tsheb. Yog hais tias cov ntxaij lim dej yog daig, ces cov theem ntawm teeb meem toxins yuav off-scale.

Tsis tas li ntawd mus saib lub serviceability koj ua tau los ntawm qhov tshem cov sensor mounted rau lub catalytic converter.

Tom qab ntawd, ib tug tshwj xeeb adapter yog tsim nyog mus cuag lub siab gauge thiab ua siab ntsuam ntawm txawv cav loads. Txawm yog hais tias tus ntaus ntawv lov, lub catalyst yog tsis tau mus kho.

Yog hais tias daig catalyst "Ford", nyob rau hauv cov ntaub ntawv no, tshem tawm cov qub ntaus ntawv, thiab teem ib lub tshiab nrog nce cov nqi nyob rau hauv nws qhov chaw. Nws tseem yuav tau teem caij es tsis txhob ntawm lub catalyst arrester los yog ib tug universal converter.

"Toyotovskie" catalyst

"Toyota" nyob rau hauv no qhov teeb meem thiab tsis txawv notable. Cov no yog cov tib hlwb nrog kub-plated los yog platinum-iridium hlau. Nyob rau hauv no hom tsheb tshiab xws peb pab kiag li lawm - lawv muaj kev cob cog rau txhua lwm yam nyob rau hauv series. Txhua yam ntawm lawv yog npaj rau tu ntawm gases los ntawm ib tug hom ntawm pollutant.

Kom lag luam ntawm lub catalyst

Yuav kom cov ntaus ntawv raws li ntev li sai tau treasured ecological teeb meem no, nws yog tsim nyog los siv kom zoo. Yog li, tus thawj thiab tseem ceeb tshaj plaws kev pom zoo, uas yuav ntev lub neej ntawm cov khoom, - ib tug zoo roj los ntawm zoo-paub thiab nrov hom. Tsis zoo roj tej zaum yuav muaj tshuaj uas muaj peev xwm ntawm kev rhuav tseg pua pua ntawm txau tsis muaj teeb meem. Tshwj xeeb yog phem cawv rau cov catalyst ( "Kalina" tsis muaj kev zam), ib tug hlau xws li tetrosvinets. Qhov no tshuaj tau ntev tau txwv nyob rau hauv ntau tsim lub teb chaws.

Nws tseem yog tsim nyog yuav tau nco ntsoov hais tias cov converter ua hauj lwm nyob rau hauv tus ntawm heev kub, yog li tsis txhob nres lub tsheb nyob qhov twg inflammable khoom dag ib ncig, nplooj, ntawv, los yog ib yam dab tsi lwm tus.

Cov neeg tsav tsheb, yog xav, tsuas yog cov catalyst yuav tsum tsis yog feem ntau muaj xws li oob khab yog lub tshuab tsis pib.

Nws yog zoo dua mus rau noj ib tawg. Tsis tas li ntawd, tsis txhob tig lub crankshaft, yog li disabling lub txim plug. Nws yuav tsum tau pib li lub engine nrog kev pab los ntawm tugboats.

Yuav ua li cas koj puas paub hais tias nws puas

Yog hais tias, piv txwv li, lub tsheb yog ib tug catalyst ( "Chevrolet Aveo" ntawm lawv), thiab koj yuav tsum to taub nws tej hauj lwm los yog tsis, qhov no muaj ntau ntau txoj kev.

Thaum lub tshuab yog kev khiav hauj lwm txhua zaus, ces thaum twg hom teeb nyob rau hauv cov kev ntsuas vaj huam sib luag, hais txog lub catalyst teeb meem, tsis sib.

Yog hais tias qhov khoom yog nyob rau hauv lub semi-neeg ua hauj lwm lub xeev, ces muaj yog ib tug tsis muaj cav fais fab hauv siab revs. Nyob rau hauv thaum sawv ntxov lub tsheb zuj zus pib. Tsis tas li ntawd lub tshuab loses ceev thiab kev noj roj qab. Tag nrho cov no pib ntsais koj teeb uas qhov khoom yuav tsum tau hloov.

Kho lawv tus kheej txhais tes

Thaum muaj ntau yam noj tsav tsheb hais tias kho ntawm cov pab kiag li lawm yog tsis tau. Nyob rau hauv qhov tseeb, nws yog. Txawm li cas los, Yog hais tias qhov khoom yog daig, koj yuav tau sim kom ntxuav nws. Yog hais tias ob peb converters nyob rau hauv lub tshuab, ces tus thawj raug tshem tawm thiab ib tug thib ob ntxuav. Koj yuav saib tau xws li ib tug catalyst - ib tug yees duab ntawm nws hauv qab no. Dej kom ib tug sib tov rau tu carburetors. Yog hais tias cov kev tshwm sim tso tawm kom pom ntau npaum li cas rog, koj yuav tsum tau tsau qhov khoom rau ib hmo nyob rau hauv ib lub thoob ntawm diesel roj.

Ntxiv mus, tus ntaus ntawv yuav sib sau ua ke thiab txaus siab rau qhov kev tshwm sim. Txawm li cas los, ua kom tiav cov hauj lwm no yog tseem pom zoo tias koj yuav ib tug ntawv tshiab. Muaj universal qauv haum rau ntau lub tsheb.
