Ua-nws-koj tus kheej catalyst kho

Yog tias qhov kev kuaj mob ntawm cov catalyst tau ua tiav, uas pom tau tias lub ntsiab lus tau txhaws thiab qhov tsis kam mus rau qhov kev tawm ntawm cov pa roj carbon monoxide nce ntxiv, tom qab ntawd cov catalyst yuav tsum tau yaug. Thaum ntxuav nrog lub tshuab nqus tsev ntxhua khaub ncaws tsis tuaj yeem ua tau (vim kev puas tsuaj rau cov khoom siv), ces qhov yuav tsum tau hloov. Yog tias nws tsis tuaj yeem ua tau zoo los hloov cov catalyst, cov catalyst yuav tsum raug tshem tawm.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab lub luag haujlwm ntawm cov catalyst

Cov tsheb niaj hnub no feem ntau yog nruab nrog ob lub converters: lub ntsiab thiab ua ntej.

Exhaust system

puag catalyst

Lub tshuab hloov ua ntej tau ua rau hauv qhov tso pa tawm (yog li nws ua kom sov mus rau qhov ntsuas kub ua haujlwm tau nrawm nrawm).

Raws li txoj cai, rau lub cav combustion sab hauv, catalytic converters yog teeb meem, raws li qhov kev tiv thaiv ntawm lub tso pa tawm tsub kom ntau. Yuav kom tswj tau qhov kub thiab txias ntawm cov catalyst hauv qee hom, nws yuav tsum ua kom muaj kev sib xyaw ua ke.

Raws li qhov tshwm sim, qhov no ua rau pom qhov txo qis hauv lub cav ua haujlwm ntawm cov roj noj thiab lub zog. Tab sis qee zaum tsuas yog tshem tawm cov catalyst tuaj yeem ua rau muaj qhov tsis zoo, vim tias cov pa roj cua ntawm cov tsheb feem ntau yog nruj nreem txuas rau lub cav tswj qhov system. Nws yog qhov zoo li tias kev ua haujlwm ntawm lub tshuab hluav taws xob sab hauv yuav ua rau hauv hom xwm txheej kub ntxhov (CHECK ENGINE), uas yuav ua rau muaj kev txwv tsis pub muaj zog, nrog rau kev siv roj ntau ntxiv.

Yuav kho lub catalyst li cas

Nyob rau hauv cov xwm txheej uas koj tseem txiav txim siab tshem tawm cov catalyst, ces koj yuav tsum xub nrhiav kom paub txog qhov yuav tshwm sim thiab txoj hauv kev los pab kom nyob ib puag ncig lawv. Nws raug nquahu kom sib txuas lus nrog cov tswv ntawm cov tsheb zoo li no (muaj ntau lub koom haum rau cov neeg nyiam tsheb ntawm qee hom hauv Is Taws Nem).

Cov xwm txheej ntawm cov cell catalyst

Feem ntau, nyob rau hauv cov ntaub ntawv qhia nyob rau hauv daim duab saum toj no, thawj oxygen sensor tsis saib xyuas lub xeev ntawm cov catalysts, kev tshem tawm ntawm lub tom kawg yuav tsis cuam tshuam rau nws cov kev nyeem ntawv, lub thib ob kub sensor yuav tsum tau dag, rau qhov no peb nruab. ib tug snag ntsia hlau nyob rau hauv lub sensor, peb ua qhov no thiaj li hais tias cov kev nyeem ntawv ntawm lub sensor tsis muaj ib tug catalyst yog sib npaug zos los yog kwv yees rau cov uas nrog lub catalyst ntsia. Yog tias lub sensor thib ob tseem yog lambda, koj yuav tsum tau ceev faj ntxiv, txij li tom qab tshem tawm cov catalyst, koj yuav xav tau flash lub ICE tswj chav tsev (qee zaum, koj tuaj yeem kho tau).

Nyob rau hauv cov ntaub ntawv qhia nyob rau hauv daim duab saum toj no, cov kev nyeem ntawv ntawm cov sensors raug cuam tshuam los ntawm lub xeev ntawm pre-catalyst. yog li, nws yuav yog qhov tseeb dua kom tshem tawm lub hauv paus catalyst thiab yaug qhov ua ntej.

Raws li qhov tshwm sim, peb tau txais qhov tsawg kawg nkaus tsis kam ntawm qhov tso pa tawm, cov kev hloov no yuav tsis muaj kev cuam tshuam rau ICE tswj qhov system, tab sis thaum lub hau ntswj ntsia hlau, qhov kev nyeem ntawm cov pa cua kub sensor yuav ua yuam kev thiab qhov no tsis yog. zoo. Tab sis qhov no yog tag nrho cov kev xav, tab sis nyob rau hauv kev xyaum nws yog tsim nyog los coj mus rau hauv tus account lub xeev ntawm catalyst hlwb.

Sagging thiab burnt tawm catalysts yog scraped.

Peb kos ib txoj kev npaj ua haujlwm - peb ntxuav cov catalyst ua ntej thiab tshem tawm lub hauv paus, thiab qhov ntawd yog nws, koj tuaj yeem pib.

Ua ntej koj yuav tsum tau tshem tawm cov pa manifold, lub pre-catalyst yog kev koom ua ke nyob rau hauv nws:

Ib qho exhaus manifold. Manifold mounting bolts

Ib qho exhaus manifold. Preneutralizer

Tshem tawm cov pa tawm manifold. Peb xaus nrog cov ntsiab lus hauv qab no:

Cells ntev, tab sis nyias nyias, yog li peb kuaj xyuas lawv cov mob kom zoo nyob rau hauv lub teeb, nws yog ib qho tsim nyog yuav tsum siv lub teeb me me tab sis ci txaus, qhov hluav taws xob tsis tshaj 12V (peb ua raws li txoj cai kev nyab xeeb).

Kev tshuaj xyuas sab nraud:

Cov mob ntawm cov hlwb yuav luag zoo tag nrho rau kev khiav ntawm 200 txhiab km.

Thaum kuaj xyuas lub teeb, pom muaj qhov tsis xws luag, nws tsis ua rau muaj kev phom sij thiab muaj kev phom sij:

Flushing yog nqa tawm yog tias tsis muaj kev puas tsuaj rau cov khoom siv (cov no suav nrog kev poob qis, hlawv, thiab lwm yam), muaj cov deposits, uas txo qhov chaw ntws. Lub honeycomb yuav tsum tau tshuab kom huv si nrog cov tshuaj tsuag carburetor los yog siv lub tshuab nqus tsev vacuum.

Yog tias muaj ntau cov deposits, ces tom qab tshuab nrog ib tug tshuaj tsuag, lub catalyst tuaj yeem tsau rau ib hmos hauv ib lub thawv nrog roj av. Tom qab ntawd, rov ua kom huv si. Tsis txhob hnov ​​​​qab txog cov pa roj recirculation channel (lwm qhov ua kom zoo ib puag ncig):

Txawm li cas los xij, yog tias koj tshem tawm cov catalyst ua ntej, tom qab ntawd cov channel yuav tsum tau ntxuav kom huv si, vim tias cov khoom tsim tawm thaum lub sij hawm tshem tawm tuaj yeem nkag mus rau hauv qhov nkag, thiab los ntawm qhov ntawd mus rau hauv lub tog raj kheej (nws yog ib qho yooj yim los twv tias daim iav lub tog raj kheej yuav tsis raug kev txom nyem me ntsis. ).

Txhua qhov kev ua haujlwm uas tau ua nrog lub ntsiab catalyst zoo ib yam li cov uas tau piav qhia rau cov piv txwv ntawm pre-catalyst. Tom qab ntawd peb pib lub rooj sib txoos, koj yuav tsum tau sib sau ua ke nyob rau hauv qhov kev txiav txim rov qab, lub gaskets yuav tsum yog tshiab los yog zoo heev ntxuav cov qub, peb sib sau ua tib zoo, tsis txhob hnov ​​qab dab tsi.

Tshem tawm lub hauv paus catalyst

Hauv kuv rooj plaub, nws yog txaus rau unscrew ob lub txiv ntseej tuav lub qhov hluav taws xob yeeb nkab, thiab khoov cov kab tom qab lub converter mus rau sab.

Kuj ceeb tias Japanese catalyst, tom qab 200 txhiab kilometers tseem yog tag nrho ntawm lub zog.

Ntawm chav kawm, ib tug pitifully kim catalyst, tab sis nws yuav tsum tau tawg los ntawm, yog li peb yuav ua kom nws yooj yim rau lub internal combustion engine ua pa. Catalyst hlwb yog yooj yim heev rau xuas nrig ntaus nrog ib tug puncher nrog ib tug 23 hli laum.

Kuv tsis tau tshem tag nrho cov catalyst cell, kuv punched ob lub qhov, qhov tshaj raug tshem tawm.

Lub hom phiaj ntawm tsuas yog ib feem ntawm cov catalyst tshem tawm yog yooj yim - cov hlwb uas nyob ib ncig ntawm cov phab ntsa yuav txo resonant vibrations, thiab lub punched lub qhov yog txaus kom tshem tawm ntawm lub zog tiv thaiv mus rau lub tso pa gases nyob rau hauv lub catalyst cheeb tsam.

Zoo li no ze ze:

Tom qab tshem tawm cov honeycombs, peb tshem tawm lawv cov seem ntawm lub catalyst chim. Txhawm rau ua qhov no, koj yuav tsum pib lub tsheb thiab khiav kom zoo kom txog thaum cov plua plav los ntawm cov ceramics tsis ntws, ces peb muab cov yeeb nkab tso rau hauv qhov chaw thiab txaus siab rau qhov tshwm sim.

Qhov zoo ntawm Ib nrab Catalyst Tshem Tawm:

• suab nrov zoo ib yam li Tshuag;
• koj tuaj yeem tshem tawm ntawm rattling hauv thaj tsam ntawm lub catalyst chim;
• nce nyob rau hauv combustion engine zog los ntawm kwv yees li 3%;
• roj noj yog txo los ntawm 3%;
• ceramic plua plav yuav tsis nkag mus rau hauv combustion chamber.

Qhov ntawd yog txhua yam, raws li koj pom, tshem tawm cov catalyst yuav tsis nthuav tawm qhov teeb meem. Hauv kev pabcuam, lawv sim ua kom kuv yug me nyuam rau kev txiav cov catalyst, ntxuav thiab rov vuam lub cev. Yog li ntawd, lawv yuav tau tso tseg tus nqi sib thooj rau "qhov nyuaj", thiab ntxiv rau, kev ua haujlwm tsis muaj txiaj ntsig.
