2024 Tus sau: Erin Ralphs | [email protected]. Kawg hloov kho: 2024-02-19 16:10

Tus tsim ntawm cov pa tso pa ntawm tag nrho cov tsheb niaj hnub no muab rau lub xub ntiag ntawm catalytic converter (catalyst). Qhov no yog qhov yuav tsum tau ua ua ntej rau kev ua raws li cov cai ib puag ncig.

VAZ-2170 tsis muaj qhov zam. Nws lub tso pa tawm kuj tau nruab nrog lub catalytic converter. Nws yuav tau tham hauv kab lus no. Peb yuav saib yuav ua li cas lub catalyst (Lada Priora) yog teem, thiab kuj tham txog cov teeb meem uas tshwm sim thaum nws malfunctions. Tsis tas li ntawd, peb yuav sim daws cov khoom siv uas siv los hloov nws.

Vim li cas peb thiaj xav tau lub tshuab hluav taws xob

Lub catalytic converter yog ib lub ntsiab ntawm cov pa pa system siv los txo cov khoom puas tsuaj (carbon oxides, nitrogen, unburned hydrocarbon tebchaw) nyob rau hauv lub pa. Qhov no yog ua tiav los ntawm kev kub nyhiab hauv cov cuab yeej vim qhov kub thiab txias thiab muaj cov pa oxygen hauv cov pa roj.

Design nta

Lub catalyst ua haujlwm li cas? "Priora" nyob rau hauv kev nkag siab ntawm nws tsim tsis txawv los ntawm lwm yam niaj hnub tshuab. Ib feem muaj lub cev steel(cov kaus poom) thiab cov khoom ua haujlwm - hlau honeycombs, qhov saum npoo uas yog coated nrog cov khoom siv uas ua rau kom muaj cua sov. Cov tom kawg yog platinum-iridium alloy.

Unburned teeb meem impurities, dhau los ntawm lub hlwb ntawm lub cuab yeej, nyob rau saum npoo ntawm catalytic txheej thiab txuas ntxiv mus hlawv nyob rau hauv qhov kev txiav txim ntawm kub kub, oxidizing yuav luag mus txog rau thaum xaus. Raws li qhov tshwm sim, ntawm qhov tso zis peb muaj qhov tso tawm nrog qhov tsawg kawg nkaus ntawm cov tshuaj phem.

Qhov chaw

Hais txog qhov chaw catalyst nyob, Priora kuj tseem tsis yog. Nws yog nyob rau hauv qab ntawm lub tso pa manifold, txoj cai nyob rau hauv lub tso pa yeeb nkab. Koj tuaj yeem pom nws yog tias koj saib tom qab ntawm lub cav. Hauv lwm lub tsheb, tej zaum nws yuav nyob tom qab ntawm cov kav dej.

Cov cim ntawm kev ua tsis tiav catalytic converter

Cov peev txheej tshaj tawm ntawm VAZ-2170 catalyst yog 140 txhiab kilometers. Txawm li cas los xij, qhov no tsis tau txhais hais tias tom qab lub mais no yuav tsum tau hloov pauv. Nws tuaj yeem ua haujlwm ntev dua, lossis nws tuaj yeem ua tsis tau txawm tias tom qab dhau 10 txhiab km. Txhua yam nyob ntawm seb koj siv lub tsheb li cas.

Yuav ua li cas nkag siab tias nws yog lub sijhawm hloov cov catalyst? "Priora", ua ib lub tsheb ntim nrog ntau yam sensors, yuav ua ntej ntawm tag nrho cov qhia rau koj paub txog nws nrog ib tug burning CHECK teeb ntawm lub dashboard (thaum nyeem cov cai, yuam kev 0420). Qhov tsis ua hauj lwm ntawm lub catalytic converter kuj nrog:

• nyuaj (ntev) txheej txheem pib lub cav;
• txo hwj chimyam ntxwv;
• nce roj noj;
• floating idle;
• tsis muaj suab nrov ntawm lub cev muaj zog;
• muaj zog (acrid) tsis hnov tsw ntawm cov pa pa.

Pib nrog sensor

Thaum koj pom cov cim saum toj no, tsis txhob poob siab tam sim ntawd. Yog vim li cas rau qhov tseeb hais tias lub tsheb tau poob nws lub qub agility tej zaum yuav ua tsis tau tejyam oxygen sensor (lambda sojntsuam). Los ntawm txoj kev, Priora muaj ob ntawm lawv: kev tswj ib qho thiab ib qho kev kuaj mob. Thawj yog tsim los txiav txim siab cov pa oxygen hauv cov pa tawm, thiab qhov thib ob yog qhia rau tus neeg tsav tsheb hauv lub sijhawm txog kev ua haujlwm tsis zoo ntawm thawj lub cuab yeej.

Ntau zaus, cov sensors no raug hu los ntawm lwm tus neeg lub npe, piv txwv li, nug seb muaj pes tsawg catalysts nyob hauv Priora thiab leej twg. Qhov no yog qhov tsis ncaj ncees lawm. Catalyst - ib, sensors - ob. Wb rov qab los rau lawv.

Muab hais tias qhov kev kuaj mob lambda sojntsuam tsis tshua muaj tsawg, ua ntej kos lub catalyst tswj sensor. "Priora" nyob rau hauv cov kev tshwm sim ntawm ib tug puas yuav ceeb toom rau koj nrog ib tug burning CHECK teeb. Nws tseem tsuas yog nyeem cov lej yuam kev nrog lub scanner thiab decrypt nws. Yog hais tias nws hloov tawm tias muaj teeb meem nrog lub lambda sojntsuam, koj muaj hmoo.

Yuav kuaj xyuas cov catalyst

Lub catalytic converter tuaj yeem kuaj tau hauv ob txoj hauv kev: los ntawm kev kuaj pom nws thiab los ntawm kev ntsuas qhov siab hauv lub kaus poom. Nyob rau hauv thawj rooj plaub, lub cuab yeej yog dismantled thiab nws cov kev ntsuam xyuas pom yog nqa tawm. Yog hais tias lub cev ntawm cov cuab yeej muaj ib qho kev cuam tshuam ntawm cov neeg kho tshuab, thiab cov hlwb pom hauvqhov, fused, catalytic converter kom meej meej puas.

Lub siab nyob rau hauv lub kaus poom ntawm lub cuab yeej raug kuaj xyuas siv lub ntsuas siab tshwj xeeb screwed nyob rau hauv es tsis txhob ntawm lub sensor tswj. Lub cav pib, warmed thiab coj mus rau 3 txhiab rpm. Yog tias lub catalyst ua haujlwm, lub siab yuav tsum tsis txhob nce siab tshaj 0.3 kgf / cm2.

Vim li cas lub catalyst tsis

Lub luag haujlwm tseem ceeb ntawm lub catalytic converter yog qhov cuam tshuam ntawm cov hlwb. Nyob rau tib lub sijhawm, lawv cov txheej txheem ua haujlwm kub hnyiab tawm, thiab lawv tus kheej pib yaj, tig mus rau hauv ib qho kev sib txuas ntxiv. Qhov no ua rau muaj kev cuam tshuam rau kev tawm ntawm cov pa tawm dawb, vim qhov tseeb, lub cav "suffocates".

ua tsis tiav ntxov ntawm cov catalyst tuaj yeem ua rau:

• siv roj zoo;
• roj nkag mus rau hauv roj;
• kev ua txhaum cai hauv qhov hluav taws xob.

Ntau npaum li cas catalyst rau Priora nqi

Lub catalyst tsis tuaj yeem kho lossis rov qab los. Nws tsuas yog hloov tau. Yog tias koj xav yuav ib lub cuab yeej tshiab, nws yuav raug nqi li ntawm 5-6 txhiab rubles, uas tsis yog pheej yig heev. Tom qab tau txais cov catalyst tshiab, Priora yuav tsis ntseeg tias muaj txoj sia nyob, tab sis nws yuav kav ntev npaum li cas?

Yog, thiab tsis txhob yuav ib lub converter siv. Leej twg paub nws tau ua haujlwm npaum li cas thiab vim li cas nws thiaj raug muag.

Hloov cov catalyst ntawm Preore nrog peb tus kheej tes

Txhawm rau hloov VAZ-2170 catalytic converter, hu rauqhov chaw pabcuam tsis tsim nyog. Qhov no tuaj yeem ua tiav hauv koj lub chaw nres tsheb. Rau qhov no koj yuav xav tau:

• set ntawm cov yuam sij;
• taub hau 13 nrog kov;
• pliers;
• taub hau ntsia hlau.

Hloov cov catalyst ("Priora") yog ua raws li hauv qab no:

1. Ntev lub tsheb ntawm qhov pom.
2. tsa lub hood, tshem tawm qhov tsis zoo ntawm lub roj teeb.
3. Txhob muab lub npog ntsej muag ntawm lub hwj chim.
4. Mus rau qhov pom. Peb unscrew (tsis tag) cov txiv ntseej qis ntawm lub clamp txuas lub ntsiab thiab ntxiv mufflers. Loosen cov txiv ntseej saum toj kawg nkaus. Tshem lub clamp thiab tshem lub nplhaib sealing.
5. Khoov lub kav hlau txais xov ntawm cov khoom siv hluav taws xob tiv thaiv hluav taws xob nrog cov pliers.
6. Unscrew peb lub txiv ntoo ruaj ntseg cov yeeb nkab flange thiab cov catalyst flange. Tshem lub phaj xauv.
7. tsa lub muffler ntxiv thiab tshem nws lub bracket ntawm lub hauv ntej cushion ntawm nws ncua kev kawm ntawv (rubber band).
8. Tshem tawm cov yeeb nkab ntawm cov muffler ntxiv los ntawm cov catalyst studs. Tshem lub gasket.
9. Txiav cov hlua khi ntawm cov khoom sib txuas ntawm kev tswj thiab kuaj cov pa oxygen sensors.
10. Tshem tawm cov sensor hlau tuav ntawm lub tshav kub tiv thaiv ntawm lub kauj iav.



11. Siv 13 lub taub hau, tshem tawm cov ntsia hlau kom ruaj lub catalyst rau lub bracket.
12. Unscrew peb fastening ceevSteering tshav kub ntaub thaiv npog. Dismantling lub screen.
13. Unscrew ob lub txiv ntoo ntawm lub twj tso kua dej twj tso kua mis (tswj). Tshem cov bracket.
14. Dismanle lub catalyst los ntawm unscrewing yim neeg rau securing nws mus rau lub tog raj kheej taub hau. Tshem tawm cov catalyst thiab gasket.
15. Nruab ib lub catalytic manifold tshiab nyob rau hauv qhov kev txiav txim rov qab.

Ua ntej txhim kho lub catalyst, nco ntsoov xyuas qhov xwm txheej ntawm lub gasket. Yog tias nws puas lawm, koj yuav tau yuav ib lub tshiab. Tsis muaj qhov xwm txheej yuav tsum tau muab lub gasket torn!

Koj yuav tsum tau kuaj xyuas qhov flatness ntawm catalyst flange. Qhov no tuaj yeem ua tiav los ntawm kev txuas rau nws, piv txwv li, tus kav hlau. Siv lub ntsuas ntsuas ntsuas, ntsuas qhov sib txawv. Yog tias lawv tshaj 0.1 hli, peb zom cov flange nto.

Puas muaj lwm txoj

Priora puas ua haujlwm yam tsis muaj kev cuam tshuam? Tau kawg nws yuav yog! Qhov tsis muaj qhov hloov pauv catalytic yuav tsis cuam tshuam rau nws qhov kev ua tau zoo, raws li qee tus neeg siv khoom siv "kev paub" thov. Yog lawm, lub tsheb yuav tsis ua raws li cov qauv tsim ib puag ncig, tab sis nws yuav tsis ua haujlwm hnyav dua.

Yog tias koj tsis xav siv nyiaj rau cov khoom siv hluav taws xob tsis tu ncua, koj tuaj yeem yuav ib lub cuab yeej thoob ntiaj teb uas yuav raug nqi ib nrab ntawm tus nqi, suav nrog kev teeb tsa. Qhov tseeb, nws yog tib lub catalytic converter nrog tib lub zog thiab cov qauv zoo sib xws. Yog lawm, thiab lawv tsuas yog tsim los ntawm tib lub chaw tsim khoom raws li cov thawj coj, thiab tus nqi rau lawv yog qis dua vim tsis muaj ntau yam kev lag luam.markups.

Zoo, yog tias koj xav ua kom yooj yim kho koj lub Priora, yuav cov nplaim taws zoo rau nws. Nws yog ntsia tsis siv lub catalyst. Nrog rau nws, lub cav fais fab yuav nce ntxiv vim kev txhim kho cov pa roj permeability, thiab lub suab ntawm lub hwj chim chav tsev yuav tau txais cov ntawv sporty.

Ib ob peb lo lus hais txog "kab laug sab"

Muaj lwm qhov kev xaiv rau kev tu, uas suav nrog kev hloov pauv tag nrho ntawm cov pa tawm. Nws hu ua "ncaj". Nws cov ntsiab lus yog tshem tawm ntawm lub cev tag nrho cov ntsiab lus uas tiv thaiv kev tawm ntawm cov pa tawm dawb, suav nrog cov catalyst.

Qhov tseem ceeb ntawm kev ntws mus tom ntej yog qhov ntxig ("kab laug sab"). Qhov no yog ib qho piv txwv ntawm lub tso pa tawm, uas txawv ntawm qhov tom kawg hauv cov yeeb nkab tshwj xeeb kev sib txuas, uas cov pa pa tawm hauv lub tog raj kheej tau xyaum tsis cuam tshuam rau cov pa tom qab.

Ob hom kab laug sab raug teeb tsa ntawm Priora: 4-1 thiab 4-2-1. Cov lej qhia seb cov kav dej sib txuas txuas li cas. Lub catalyst ntxig ("Priora") 4-1 muab rau kev sib txuas ntawm plaub kav rau hauv ib qho. Hauv "kab laug sab" 4-2-1, cov kav dej sib sau tau ua ntej ua khub, thiab tom qab ntawd sib sau ua ke.

Nws ntseeg tau tias qhov zoo tshaj plaws cov yeeb nkab txuas rau VAZ-2170 yog 4-1 lub tswv yim, tab sis lwm qhov tsis zoo dua. Nws yog ib qho tseem ceeb uas lub fastening ntsiab ntawm tag nrho cov seem ntawm lub tso pa system match, vim hais tias nyob rau hauv tas li ntawd mus rau lub insert, koj kuj yuav tsum tau yuav ib tug resonator thiab ib tug silencer.

Yuav ua li cas txuas lub neej ntawm cov catalyst

Thaum kawg, tshawb xyuas cov lus qhia uas yuav pab koj tsis taurov qab mus rau lub ntsiab lus ntawm kev hloov cov catalytic converter:

1. Tsis txhob siv roj av tsis zoo. Qhov kev txiav txim siab no yuav cawm tsis tau tsuas yog cov catalyst xwb. Lub Priora tsis yog txhua yam ntawm lub tsheb uas koj tuaj yeem nchuav txhua yam uas kub hnyiab rau hauv lub tank.
2. Tsis txhob cia roj nkag mus rau hauv roj. Pom tias cov pa tawm tau txais cov xim xiav, tsis txhob tub nkeeg heev los xyuas cov compression hauv lub tog raj kheej. Muaj peev xwm hnav ntawm qhov chaw ntawm pawg piston, vim cov roj nkag mus rau hauv lub tog raj kheej.
3. Ua tib zoo mloog rau lub dashboard. Yog lub teeb ceeb toom CHECK los, thiab lub tsheb pib nyuaj, poob lub zog, tsis txhob tos nrog kev kuaj mob.
