Lub catalyst nyob rau hauv lub tsheb niaj hnub no yog ib feem tseem ceeb ntawm cov pa system. Cov khoom no ua ob yam. Qhov no yog kev ntxuav ntawm cov pa roj ua ntej lawv nkag mus rau hauv cov huab cua, nrog rau kev txo qis kev tawm tsam rau lawv txoj kev tawm. Lub zog uas lub cav yuav tsim nyob ntawm tus catalyst. Yog tias mam li nco dheev lub tsheb tsis tuaj yeem mus nrawm dua li yav dhau los, lossis kev siv roj ntau ntxiv, ces muaj teeb meem xws li cov khoom siv hluav taws xob txhaws. Cov tsos mob no tuaj yeem nrog rau lwm yam ua haujlwm tsis zoo, tab sis feem ntau lawv cuam tshuam nrog cov catalyst. Xav txog lwm cov cim qhia ntawm kev sib kis ntawm lub caij, nrog rau cov kev daws teeb meem.

Cov cim tseem ceeb ntawm lub ntsiab tsis ua haujlwm

Cov neeg tsav tsheb, txawm tias muaj kev paub me ntsis, yuav tuaj yeem txiav txim siab yam tsis muaj teeb meem uas muaj kev ua haujlwm tsis zoo hauv cov pa tawm. Yog tias cov pa tso pa tawm tsis zoo los ntawm lub cev, qhov no yuav cuam tshuam rau tus cwj pwm ntawm lub tsheb thiab lub suab ntawm lub cav.

Poob zog

Lub tsheb yuav nyuaj nrawm nrawm.

Qhov no, qhov teeb meem no yuavtsuas xav ib pliag xwb. Lub sijhawm no nyob ntawm seb cov kab mob kis hnyav npaum li cas thiab seb nws puas nyob zoo. Cov tsos mob ntawm qhov clogged catalytic converter yog qeeb acceleration hauv qis zog. Yog tias koj mus rau qhov siab dua, ces lub cev muaj zog yuav ua haujlwm hauv nws hom li qub. Tsis tas li ntawd, thaum tsav tsheb, tus neeg tsav tsheb yuav hnov tias muaj lub nra hnyav heev hauv lub cev, uas tsis tso cai kom nrawm txaus.

Chek Engine

Nov yog ib qho ntawm cov tsos mob uas qhia tau tias muaj kev cuam tshuam.

Piv txwv li, yog tias qhov cuam tshuam hnyav heev, ces ECU yuav teeb lub teeb. Hauv qhov no, tus neeg tsav tsheb yuav tsum xyuas qhov ua haujlwm tsis zoo. Yog tias lub tsheb tau nruab nrog lub khoos phis tawj on-board, ces cov lus yuam kev yuav tshwm rau ntawm nws: "Clogged catalytic converter". Cov tsos mob zoo ib yam - poob lub zog, teeb meem nrog kev ua haujlwm ntawm lub cav. Qhov no tau tshaj tawm los ntawm qhov yuam kev P0420.

siv roj ntau

Vim muaj kev sib kis ntau dhau ntawm cov catalyst, kev siv roj tuaj yeem nce ntxiv. Nws yog ib qho tsim nyog yuav tsum tau xyuam xim rau qhov tseeb tias kev noj haus tsuas yog qhia txog cov teeb meem hauv cov pa tawm yog tias muaj lwm cov tsos mob ntawm cov kab mob txhaws - poob ntawm lub zog thiab kev nrawm nrawm.

Vim li cas lub ntsiab tsis

Lub tsheb hloov pauv tsis tuaj yeem ua tsis tau los ntawm nws tus kheej. Yog hais tias muaj teeb meem nrog rau qhov no los yog lub cav tsis xav kom muaj zog thiab poob nws lub zog, qhov no qhia tau hais tias lub catalyst yog deformed los yog clogged nyob rau hauv lub system.

Cov tsos mob no yuav tshwm sim rau qee yam.

Roj tsis zoo

Yog tias qhov sib xyaw ntawm cov roj av thiab cov huab cua tsis ua kom kub hnyiab tawm hauv lub tog raj kheej lub cav, ces kev sib txuas yuav xaus rau hauv cov catalyst lossis hauv cov pa hluav taws xob. Tom qab ntawd lub ntsiab qhov chaw ntawm lub tso pa system yog melted. Cov khoom combustion nyob rau hauv lub converter thiab tiv thaiv kom tsis txhob muaj gases hla ntawm qhov yuav tsum tau ceev. Vim li ntawd, lub kaw lus cia li kaw.

Tsis zoo catalyst

Automakers ua tiav tsheb nrog cov khoom zoo thiab khoom siv. Tab sis yog tias ib yam dab tsi hauv lub tsheb hloov, ces nws tsis yog qhov tseeb tias tus tswv tau muag cov khoom seem zoo. Yog tias lub tshuab hloov pauv tsis zoo lossis tsis yog thawj zaug tau teeb tsa hauv lub tsheb, ces muaj kev pheej hmoo loj uas cov cell catalyst me dhau. Vim lawv qhov loj me tsis txaus, lawv tau yooj yim txhaws nrog cov khoom combustion.

Ntau zaus, tag nrho cov cim qhia ntawm kev ua haujlwm tsis zoo thiab cov tsos mob ntawm cov kab mob txhaws tshwm sim hauv Asmeskas cov tsheb uas tau ua dhau los hauv Tebchaws Meskas. Hauv Tebchaws Meskas, cov chaw nres tsheb roj tau muag cov roj av zoo dua qub, uas ua rau tsawg kawg ntawm cov khoom tsis raug hlawv thaum lub sij hawm combustion. Catalysts nyob rau hauv xws li tsheb nrog me me honeycombs - nyob rau hauv Russia lawv tuag nyob rau hauv lub shortest tau lub sij hawm.

Teeb meem nrog lub cav ua haujlwm

Qhov no yog lwm qhov laj thawj. Raws li qhov tshwm sim, tus tswv tau txais ib qho clogged catalyst. Cov tsos mob ntawm qee qhov teeb meem hauv lub cavyog imperceptible, thiab nws yog ib qho nyuaj heev los hais kom raug raws li qhov ua tau raws nraim li cas ua rau kev loj hlob ntawm cov khoom siv roj combustion nyob rau hauv cov pa system tsis muaj kev kuaj mob hnyav. Lub "lub hlwb" ntawm lub tsheb raug kuaj xyuas thiab tag nrho cov lej yuam kev raug nyeem.

txoj kev phem

Yog tias lub tsheb siv tsis tu ncua ntawm txoj kev tsis zoo, ces muaj kev pheej hmoo loj uas nws tuaj yeem deformed. Txawm tias me ntsis tshuab yog txaus rau cov hlwb pib tawg los yog deform. Txhawm rau kom tsis txhob hloov cov khoom kim, nws yog qhov zoo dua los ua tib zoo hla cov teeb meem, xws li kev nrawm nrawm.

Diesel xyaw

Tsis muaj qhov cuam tshuam rau cov khoom siv hluav taws xob zoo li no. Muaj cov lim dej tsis zoo, nws ua haujlwm tib yam li cov catalytic converter hauv lub cav roj av. Lwm qhov txawv yog tus nqi. Lub lim dej yuav raug nqi peb zaug ntau npaum li cov roj av.

Cov tsos mob ntawm qhov clogged catalytic converter ntawm lub diesel yog zoo ib yam li cov tswv ntawm roj av xyaw tej zaum yuav ntsib. Qhov no yog qhov poob ntawm lub zog, lub cav tsis kam pib, nce roj noj.

Yuav ua li cas ntsuas lub catalyst ntawm lub tsheb

Koj tuaj yeem kuaj xyuas qhov no ntawm koj tus kheej, yog tias koj muaj kev paub, kev txawj ntse thiab khoom siv tsim nyog. Kuj xyuas cov neutralizer hauv txhua qhov kev pabcuam. Muaj peb txoj kev kuaj mob.

Visual way

Kev tshuaj xyuas yooj yim yuav tsum nyob ntawm no. Teeb meem hauv kev ua haujlwm ntawm qhov system no tuaj yeem txheeb xyuas tau yooj yim los ntawm kev saibnws. Yog tias muaj ntau yam deformations ntawm lub cev, muaj qhov tshwm sim ntau uas cov hlwb puas lawm. Nws yog tsis yooj yim sua kom paub tias cov catalyst yog clogged los ntawm sab nraud. Nws yuav tsum tau muab tshem tawm.

Qhov teeb meem yog qhov nyuaj ntawm kev rhuav tshem txoj haujlwm. Nws yog ib qho tsim nyog yuav tsum tau tsav lub tsheb mus rau qhov chaw flyover los yog lub qhov. Tsis tas li ntawd, txhua lub tsheb muaj nws tus kheej txoj cai installation. Tsis tas li ntawd ib qho teeb meem tshwm sim yog qhov nplaum ntawm lub retainer uas tuav lub converter. Yog li ntawd, feem ntau dismantling yog nqa tawm tsuas yog hloov nrog lub grinder.

Yog tias qhov raug tshem tawm, ces nws raug tshuaj xyuas qhov khoob. Yog tias cov cuab yeej tau txhaws nrog cov av, nws tuaj yeem ntxuav tau, tab sis nws yog qhov zoo dua los hloov nws. Nws yuav tsum nco ntsoov tias qhov kev tshuaj xyuas no tuaj yeem ua tsis tau ntawm cov neeg nruab nrab. Yog li ntawd, muaj lwm txoj hauv kev los txiav txim siab yog tias cov catalyst yog clogged.

Back pressure test

Txoj kev no tsis tas yuav rhuav tshem. Lub hauv paus ntsiab lus ntawm qhov kev xeem yog ntsuas lub siab ntawm cov pa tso pa tawm. Cov ntaub ntawv yog ces muab piv nrog cov tsis zoo tagnrho. Txhawm rau ua qhov haujlwm, koj xav tau lub ntsuas siab thiab lub adapter kom suav nrog hauv qhov system. Lub tsheb yuav tsum tau muab ntsia rau ntawm lub flyover lossis lub qhov. Tom ntej no, thawj lambda sojntsuam raug tshem tawm, thiab lub ntsuas siab txuas nrog hloov. Nws yog ib qho tseem ceeb kom txuas nws mus rau lub kaw lus kom txhua yam nruj li sai tau.

Tom ntej no, pib lub cav thiab nce qhov nrawm mus rau 2500-3000, thiab kho qhov ntsuas qhov siab. Yog hais tias lub siab yog kwv yees li 0.3 kgf / cm 2, ces txhua yam zoo nrog lub converter. Yog 0.35kgf/cm2, ces (yog tias lub cev muaj zog tsis tau hloov kho) koj yuav tsum xyuam xim rau nws. Thaum qib yog 0.5 kgf / cm2 thiab siab dua, lub converter yog faulty.

Nyob hauv kaw

Feem ntau, nyob rau hauv cov tsheb niaj hnub no, lub computer nws tus kheej qhia rau tus neeg tsav tsheb yog tias cov catalyst tau txhaws. Cov tsos mob dab tsi yuav tshwm sim ntawm lub tsheb yam tsis muaj kev kuaj mob - tau piav qhia saum toj no. Qhov kev daws teeb meem zoo tshaj plaws yog kev hloov pauv. Tab sis nws kim heev, muaj ntau lub chaw pabcuam muab rau nruab ib lub nplaim taws.
