Txhua lub tsheb muaj qhov tso pa tawm. Nws suav nrog ob peb yam txheej txheem. Lub ntsiab sawv daws yuav yog lub collector, resonator thiab muffler. Tsis tas li ntawd, lub kaw lus tuaj yeem siv lub corrugation uas txo cov kev vibrations. Tab sis kuj yog ib qho yuav tsum tau muaj nyob rau hauv cov tsheb nrog Euro-3 thiab cov qauv siab dua yog cov catalyst. Nws yog dab tsi, thiab kuv puas yuav tsum tau tshem tawm cov catalyst? Peb yuav tham txog hauv peb tsab xov xwm hnub no.

yam ntxwv

Catalyst yog ib qho tseem ceeb ntawm cov pa tawm ntawm lub tsheb, uas yog tsim los ntxuav cov pa roj los ntawm cov hlau tsis zoo thiab oxides. Sab nraud, cov khoom yog ib hom thawv nrog lub rooj hlau.

Inside nws yog ceramic muab tub lim. Cov tom kawg muaj ntau yam honeycombs, dhau los ntawm cov pa roj purified. Txhawm rau kom ceev cov tshuaj tiv thaiv hauv lub caij, cov tshuaj tshwj xeeb-catalysts yog siv. Cov no yog, raws li txoj cai, kim hlau:palladium, rhodium thiab lwm yam. Nws yog lawv uas hloov cov khoom tsis zoo rau hauv cov oxides uas tsis muaj teeb meem.

About no peev txheej

Tsis muaj peev txheej tshwj xeeb lossis kev cai los hloov cov khoom no. Thiab yog, cov lej sib txawv heev. Rau qee tus tswv tsheb, cov catalyst mus txog 150 txhiab, lwm tus ntsib teeb meem tom qab 60. Yog vim li cas? Qhov tseeb yog tias cov peev txheej thiab cov xwm txheej ntawm cov catalyst nyob ntawm ntau yam. Qhov no yog lub serviceability ntawm lub ignition system, roj zoo, tsheb khiav hauj lwm tej yam kev mob. Yog li ntawd, lub malfunction ntawm lub caij yuav tsum tau txiav txim los ntawm cov yam ntxwv nta. Peb teev lawv hauv qab no.

Yuav ua li cas txheeb xyuas qhov catalytic converter tsis ua haujlwm?

Thawj cov tsos mob qhia tias muaj kev ua haujlwm tsis zoo yog lub teeb daj "Check Engine" ntawm lub ntsuas ntsuas. Vim li cas nws thiaj raug hluav taws? Nws yog qhov yooj yim: hauv lub tsheb, qhov xwm txheej ntawm lub lim tau saib xyuas los ntawm cov pa oxygen sensors (feem ntau muaj ob ntawm lawv). Qhov thib ib yog mus txog lub catalyst, qhov thib ob yog tom qab nws. Thiab yog tias cov sensors pom qhov sib txawv ntawm cov qauv hauv toxicity (ntau dua, hais txog cov pa oxygen seem), lub teeb liab raug xa mus rau lub tshuab hluav taws xob tswj lub cav, thiab tom qab ntawd lub teeb daj teeb.

Lub cim tom ntej yog txo lub zog thiab nrawm nrawm. Nws paub tias qhov tsawg dua tiv thaiv kev tso tawm ntawm cov pa roj, qhov zoo dua qhov kev khawb ntawm lub tog raj kheej. Yog hais tias lub catalytic converter yog clogged, nws yog qhov nyuaj dua rau cov pa kom dim. Raws li, lub cev muaj zog yuav "strangled" los ntawm nws tus kheej gases. Tus neeg tsav tsheb yuav hnov qhov no tam sim ntawd los ntawm tus cwj pwm tsis zoo ntawm lub tsheb. Lub tshuab ua tsis muaj zog thiab tsis muaj zog.

Qhov teeb meem no tuaj yeem nrognce roj noj. Txij li thaum lwm cov ntaub ntawv tau txais los ntawm cov sensors, ECU hloov cov kev sib xyaw ntawm cov roj sib tov. Tsis tas li ntawd, tus neeg tsav tsheb cia li nias lub roj ntau dua li niaj zaus (tom qab tag nrho, lub tsheb khaws nrawm dua). Qhov no nce kev noj 5-10 feem pua.

Cov kws tshaj lij tsis qhia ncua kev tshem tawm qhov teeb meem no. Qhov no yog tshwj xeeb tshaj yog muaj tseeb nyob rau hauv cov ntaub ntawv uas ib feem ntawm lub muab tub lim tau tawg, thiab tus neeg tsav tsheb hnov ib tug yam ntxwv ringing. Qhov no yog qhov txaus ntshai vim tias cov plua plav ceramic tuaj yeem nkag mus rau hauv lub cav (tshwj xeeb yog tias cov catalyst nyob ze rau lub tog raj kheej - nws yog welded ncaj qha mus rau hauv lub tso pa manifold).

Tus catalyst puas raug tshem tawm?

Tsuas muaj ob txoj hauv kev rau qhov xwm txheej no. Qhov no yog qhov hloov ntawm cov catalyst nrog ib qho tshiab lossis nws tshem tawm. Tsis muaj leej twg siv thawj qhov kev xaiv. Tom qab tag nrho, tus nqi ntawm lub lim tshiab yuav yog los ntawm 30 txhiab rubles. Nws yog qhov pheej yig dua kom tshem tawm nws, yog li tso koj tus kheej los ntawm kev hloov pauv raws sijhawm. Tseeb, nyob rau hauv cov ntaub ntawv no, tus tswv yuav tsis xav txog qhov teeb meem ntawm yuav ib tug tshiab catalyst tom qab 60 txhiab kilometers. Yog li ntawd, thaum nug seb puas muaj peev xwm tshem tawm cov catalyst, cov kws tshaj lij tsuas yog cov lus teb zoo.

txiaj ntsig

Yuav hloov dab tsi yog tias koj tshem tawm cov catalyst? Ntawm qhov zoo, ua ntej ntawm tag nrho cov, nws tsim nyog sau cia cov nyiaj khaws cia. Tom qab tag nrho, cov txheej txheem rau tshem tawm ib tug catalyst nqi tsis ntau tshaj 15 txhiab, thaum ib tug tshiab catalyst nqi los ntawm 30. Qhov kev ua hauj lwm no kuj tso cai rau koj mus qhib lub tso pa system (piv txwv li, txhim kho ib tug kev ua si tso manifold). Lwm qhov ntxiv yog qhov nceICE kev pab. Tom qab tag nrho, cov plua plav ceramic nyob rau hauv qhov kev tshwm sim ntawm hnav cov muab tub lim tsis tuaj yeem nkag mus rau hauv lub tog raj kheej kab noj hniav thiab ua rau lawv puas tsuaj txhua txoj kev.

Tam sim no hais txog cov teeb meem ntawm kev nce lub zog thiab txo kev siv. Qhov no puas yuav muaj tseeb yog tias nws tau npaj tshem tawm cov catalyst? Kev tshuaj xyuas cov neeg uas tau ua cov txheej txheem no qhia txog cov hauv qab no. Yog tias peb sib piv cov ntsuas uas nyob rau ntawm qhov clogged catalyst ua ntej thiab tom qab tshem tawm, nws yuav muaj zog ntxiv. Tab sis nws yog qhov tsis tseem ceeb - tsuas yog 3-5 feem pua, thiab txawm tias tom qab ntawd vim tias cov roj av yav dhau los tsis tuaj yeem tso tawm lub tog raj kheej chamber. Yog li, lub zog ntawm lub tsheb yuav tsis siab dua li lub Hoobkas nqi. Tib yam siv rau kev siv roj. Yog tias koj tshem tawm cov catalyst uas yav tas los txhaws, txawm li cas los xij, yuav muaj kev txo qis hauv kev noj.

Flaws

Ntawm cov minuses, nws tsim nyog sau cia qhov nce hauv cov pa toxicity. Txij li thaum tsis muaj cov lim dej hauv qhov system, qhov tsis hnov tsw ntawm gases yuav pungent. Tsis tas li, yog tias tshem tawm tsis raug, lub suab tso tawm tuaj yeem hloov pauv. Nws yuav tau txais me ntsis nrov. Txhawm rau tiv thaiv qhov no, es tsis txhob siv cov yeeb nkab yooj yim, cov nplaim taws yog welded rau hauv qhov chaw ntawm cov catalyst. Nws muaj cov qauv ntxeem tau sab hauv thiab ib nrab dampens vibrations. Vim li ntawd, lub suab nrov tseem nyob hauv lub Hoobkas.

Yuav ua li cas ntxiv yog tias koj tshem tawm cov catalyst? Qhov tsis zoo tom ntej yog tias tom qab tshem tawm, koj yuav tsum tau nruab ib lub snag, lossis nyem lub ECU rau tus qauv Euro-2. Qhov no yuav tsum tau coj mus rau hauv tus account yog tias koj npaj yuav tshem tawm cov catalyst koj tus kheej ntawm VAZ-2114. Raws li kev txheeb xyuas, txoj hauv kev yooj yim tshaj plaws yog mus yuav ib qho kev npaj ua tiav thiabnruab nws nyob rau hauv tus txheej txheem qhov ntawm cov pa sensor. Thaum kawg ntawm tsab xov xwm, peb yuav tham ntxiv txog ntau yam ntawm cov ntsiab lus no.

Yuav ua li cas tshem cov catalyst nrog koj tus kheej txhais tes?

Technology yog qhov yooj yim heev. Nws muaj nyob rau hauv tshem cov ceramic packing ntawm catalyst. Ua li no, lub tsheb tau tsav mus rau hauv lub qhov tshuaj ntsuam xyuas, thiab cov catalyst raug tshem tawm ntawm nws. Yuav ua li cas tshem tawm cov catalyst? Feem ntau nws muaj tus qauv bolt-on fasteners. Tom ntej no, nrog kev pab los ntawm ib tug grinder, ib feem ntawm lub cev yog txiav. Xws li ib lub qhov yog ua kom nws yooj yim mus rau sab hauv. Tom qab ntawd, nrog kev pab los ntawm ib tug rauj thiab ib tug chisel, lub ceramic muab tub lim yog khob tawm mechanically.

Tom qab ntawd, lub hau yog welded los ntawm lub tshuab vuam, thiab cov cuab yeej raug ntsia rov qab. Tab sis txij li thaum lub ntsuas pa oxygen yuav cuam tshuam qhov yuam kev (nrog rau lub teeb sib txuas ntawm lub ntsuas hluav taws xob), lub tshuab hluav taws xob yuav tsum tau teeb tsa ua ntej. Tom qab ntawd, lub tsheb yuav npaj txhij rau kev ua haujlwm tag nrho.

Technology tshem tawm ntawm cov chaw pabcuam

Cov kev pabcuam feem ntau tshem tawm cov catalyst thiab tom qab ntawd hloov nws nrog cov nplaim taws. Qhov no yog kev daws teeb meem ntau dua. Nyob rau hauv cov ntaub ntawv no, peb tau txais tsis tau tsuas yog ib tug ntsiag to thiab qab ntxiag tso pa (tsis muaj ringing, uas tej zaum yuav nyob rau hauv lub yav dhau los version), tab sis kuj tsawg cua sov ntawm cov pa tawm ntawm lawv tus kheej. Hauv lwm lo lus, los ntawm qhov kub thiab txias, lub muffler, uas yog qhov kawg txuas hauv cov saw hlau, yuav pab tau peb ntev dua.

Yuav ua li cas tshem tawm VAZ catalyst? Txoj kev tshem tawm yog raws li nram notxoj kev. Lub tsheb tau nruab rau ntawm lub nqa, tom qab ntawd cov kws kho mob tshwj xeeb txiav tawm cov catalyst. Tom qab ntawd, qhov kev ncua deb ntawm cov kav dej yog ntsuas, thiab cov nplaim taws ntawm qhov xav tau ntev yog xaiv raws li qhov ntev. Nws yog ib qho tseem ceeb kom paub tias txoj kab uas hla ntawm cov pa tawm tuaj yeem sib txawv. Thaum xaiv ib feem raws li qhov ntev, tus tswv welds tus nplaim ntes los ntawm argon arc vuam. Tom ntej no, lub tshuab nqis los ntawm lub nqa, thiab tus tswv flashes lub tshuab hluav taws xob. Ib lub firmware tshiab yog "dhau" los ntawm kev kuaj mob txuas, uas ua raws li tus qauv Euro-2. Nws tsis muaj cov catalyst, yog li lub tshuab kuaj xyuas lub teeb yuav tsis teeb.

Ntau yam snags

Tus snag nws tus kheej yog tus neeg kho tshuab spacer. Nws yog ntsia nyob rau hauv pem hauv ntej ntawm lub thib ob lambda sojntsuam thiab tso cai rau koj mus kho qhov tseem ceeb kom lub computer tsis tso saib qhov yuam kev thaum lub internal combustion engine khiav tsis muaj catalyst. Muaj peb hom kev dag:

• Empty. Nws yog ib lub raj nrog lub qhov nyias nyias ntawm qhov kawg. Ntawm qhov tod tes, ib qho oxygen sensor yog screwed rau nws. Lub kaw lus ua haujlwm yooj yim: me me ntawm cov pa hluav taws xob dhau los ntawm lub raj, yog li lub ntsuas ntsuas tsis pom qhov ntau dhau, thiab lub teeb ntawm lub ntsuas vaj huam sib luag tsis teeb.
• Nrog ceramic filling. Nyob rau hauv lub snag nws tus kheej muaj me me hlwb uas purify ib feem ntawm cov gases nyob rau hauv thiaj li yuav kho ib txwm muaj nuj nqis los ntawm lub sensor.
• Angular. Lawv tuaj yeem ua tau ob qho tib si khoob thiab puv. Siv nyob rau hauv rooj plaub uas lub installation ntawm ib tug pa snag yog teeb meem vim tsis muaj chaw.

Dab tsihais txog tus nqi ntawm cov cuab yeej, nyob ntawm seb hom thiab tsim, nws tuaj yeem yuav ntawm 1-4 txhiab rubles.

Yog li peb xav seb puas yuav tsum tau tshem tawm cov catalyst. Nyob rau tib lub sijhawm, cov khoom no tsis ua haujlwm (clogs). Yog li ntawd, txhua tus tswv tsheb yuav sai lossis tom qab tshem tawm cov catalyst. Raws li kev xyaum qhia, qhov kev xaiv ua tau zoo tshaj plaws yog los hloov nws nrog cov nplaim taws, tom qab ntawd los ntawm kev teeb tsa ntawm lub tshuab hluav taws xob lossis nrog lub flashing ntawm lub tshuab hluav taws xob. Tab sis nws yog ib qho tsim nyog sau cia tias ECU firmware yog cov txheej txheem ua lub luag haujlwm, thiab tsuas yog cov kws tshaj lij tsim nyog yuav tsum tau ntseeg nrog kev lag luam no.
