Ita-iwe-iwe pachako kugadzirisa kugadzirisa

Kana kuongororwa kweiyo catalyst yakaitwa, iyo yakaratidza kuti chinhu chakavharwa uye kushorwa kwekufamba kwemagasi ekupedza kwakawedzera zvakanyanya, ipapo iyo catalyst inoda kugezwa. Kana kushambidza ne catalyst cleaner hazvibviri (nekuda kwekukuvara kwemagetsi), ipapo chikamu chichafanira kuchinjwa. Kana zvisingagoneke mune zvehupfumi kutsiva iyo catalyst, iyo catalyst ichafanirwa kubviswa.

Nheyo yekushanda uye basa re catalyst

Mota dzemazuva ano dzakawanda dzine maconverter maviri: main and preliminary.

Exhaust system

base catalyst

I-pre-converter inovakwa mukati mekupedza manifold (saka kudziya kwayo kusvika kune tembiricha yekushanda inokwidziridzwa zvakanyanya).

Nechepfungwa, kune enjini dzinopisa mukati, catalytic converters inokuvadza, sezvo kushorwa kweiyo turakiti rekuburitsa kunowedzera zvakanyanya. Kuti uchengetedze tembiricha inodiwa yecatalyst mune mamwe modes, zvinova zvakafanira kupfumisa musanganiswa.

Nekuda kweizvozvo, izvi zvinotungamira kuderera kunooneka kwekuita kweinjini maererano nekushandiswa kwemafuta uye simba. Asi dzimwe nguva kungobvisa chinokonzeresa kunogona kuita kuti zvinhu zvinyanye kushata, sezvo gasi rekupedza gasi pamota zhinji rakanyatsobatanidzwa kune injini yekudzora system. Zvingangodaro kuti kushanda kweinjini yekupisa kwemukati kuchaitwa mumamiriro ekukurumidzira (CHECK ENGINE), izvo pasina mubvunzo zvinotungamirira kumagetsi emagetsi, pamwe nekuwedzera kwemafuta.

Nzira yekugadzirisa sei catalyst

Kana iwe uchiri kusarudza kubvisa iyo catalyst, iwe unofanirwa kutanga waziva nezve mhedzisiro uye nzira dzekubatsira kutenderera navo. Zvinokurudzirwa kutaurirana nevaridzi vemotokari dzakadaro (pane nhamba huru yemakirabhu evanoda mota yeimwe mhando paInternet).

Mamiriro emagetsi anokonzeresa

Kazhinji, munyaya inoratidzwa mumufananidzo uri pamusoro, yekutanga okisijeni sensor haitaridzi mamiriro ezvinokonzera, kubviswa kwekupedzisira hakuzokanganisa kuverenga kwayo, yechipiri tembiricha sensor inofanira kunyengedzwa, nokuti isu tinoisa. snag screw pasi pe sensor, tinoita izvi kuitira kuti kuverenga kwe sensor pasina catalyst kwakaenzana kana kuenzana kune avo vaiva nekasikisi yakaiswa. Kana iyo yechipiri sensor iriwo lambda, iwe unofanirwa kuchenjerera, sezvo mushure mekubvisa iyo catalyst, iwe ungangoda kupenya iyo ICE control unit (mune dzimwe nguva, unogona kugadzirisa).

Muchiitiko chinoratidzwa mumufananidzo uri pamusoro, kuverenga kwema sensors kunokonzerwa nehurumende yepre-catalyst. saka, zvingava zvakanyanya kunaka kubvisa base catalyst uye sukurudza yekutanga.

Nekuda kweizvozvo, isu tinowana kushomeka kwekupokana kweiyo exhaust turakiti, shanduko idzi hadzizove nemhedzisiro pane iyo ICE control system, asi kana screw yaiswa mukati, kuverenga kweiyo exhaust gasi tembiricha sensor kuchave kukanganisa uye izvi hazvisi izvo. kugona. Asi iyi ndiyo yose dzidziso, asi mukuita zvakakosha kufunga nezvemamiriro ekugadzirisa masero.

Kusaga uye kutsva zvinokonzeresa zvinoraswa.

Isu tinogadzira chirongwa chebasa - isu tinosuka iyo yekutanga catalyst uye kubvisa iyo base, uye ndizvozvo, unogona kutanga.

Kutanga iwe unofanirwa kubvisa manifold ekupedza, iyo pre-catalyst inosanganiswa mairi:

Manifold exhaust. Manifold mounting bolts

Manifold exhaust. Preneutralizer

Bvisa manifold exhaust. Tinopedzisa nemashoko anotevera:

Masero akareba, asi akaonda nzira, saka tinoongorora mamiriro avo nekuchenjerera muchiedza, zvinokurudzirwa kushandisa diki asi rakajeka rakakwana rechiedza sosi, iyo voltage isingapfuuri 12V (tinotevera mitemo yekuchengetedza).

Kuongorora kwekunze:

Mamiriro emasero anenge akakwana pakumhanya kwe200 zviuru zvemakiromita.

Paunenge uchitsvaga chiedza, chikanganiso chiduku chakawanikwa, hachina ngozi uye kukuvadza:

Flushing inoitwa kana pasina mechanical kukuvara (izvi zvinosanganisira subsidence, kupisa, nezvimwewo), kuvapo deposits, izvo zvinonyanya kuderedza kuyerera nzvimbo. Muzinga weuchi unofanirwa kunyatsofuridzirwa necarburetor spray kana kushandisa foam catalyst cleaner.

Kana pane akawanda madhipoziti, zvino mushure mekuputika nepfapfaidzo, iyo catalyst inogona kunyikwa husiku mumudziyo une dizeli mafuta. Mushure meizvi, dzokorora kuchenesa. Usakanganwa nezve exhaust gasi recirculation chiteshi (imwe yezvakatipoteredza hunyengeri):

Kana iwe zvakadaro wakabvisa iyo yekutanga catalyst, ipapo chiteshi chinofanirwa kushambidzwa zvakakwana, sezvo crumb yakaumbwa panguva yekubviswa inogona kupinda mukati, uye kubva ipapo ichipinda mumasilinda (zviri nyore kufungidzira kuti cylinder girazi haizotamburi zvishoma. )

Mabasa ese anoitwa neiyo main catalyst akafanana neaya anotsanangurwa semuenzaniso we pre-catalyst. ipapo tinotanga gungano, iwe unoda kuungana munhevedzano yakarongeka, magasi anofanira kunge ari matsva kana akanyatsocheneswa akare, tinoaunganidza zvakanyatsonaka, usakanganwa chero chinhu.

Kubvisa base catalyst

Mune mhaka yangu, zvakanga zvakakwana kusunungura nzungu mbiri dzakachengetedza pombi yekubuda, pamwe nekukotamisa mutsara mushure mekushandura kudivi.

Zvinoshamisa Japanese catalyst, pashure 200 zviuru makiromita achiri azere nesimba.

Ehe, chinosiririsa chinodhura chinodhura, asi chinoda kuputswa, saka isu tichaita kuti zvive nyore kuti injini yekupisa yemukati kufema. Masero eCatalyst ari nyore kwazvo kubaya nepuncher ine 23 mm drill.

Handina kubvisa yese catalyst cell, ndakarova maburi maviri, kuwanda kwakabviswa.

Chinangwa chechikamu chete chekubvisa chinokonzera chiri nyore - masero anoramba akakomberedza masvingo achaderedza kudengenyeka kwemhepo, uye gomba rakaputirwa rinokwana kuti ribvise kuwedzera kwekupikisa kunopfuura kwemagasi emhepo munzvimbo ye catalyst.

Zvinotaridzika seizvi padhuze:

Mushure mokubvisa mizinga yeuchi, tinobvisa zvimedu zvadzo kubva mubhodhoro re catalyst. Kuti uite izvi, unofanirwa kutanga motokari uye kuifambisa zvakanaka kusvikira guruva rekeramic ramira kuyerera.Ipapo tinoisa pombi yekubuda panzvimbo uye tinonakidzwa nechigumisiro.

Zvakanakira Kubvisa Chikamu Catalyst:

• nhanho yeruzha yakafanana nestock;
• iwe unogona kubvisa kutinhira munzvimbo ye-catalyst barrel;
• kuwedzera mukati meinjini yekupisa simba neinenge 3%;
• kushandiswa kwemafuta kunoderedzwa ne3%;
• guruva receramic haringapindi muimba yekupisa.

Ndizvo chete, sezvawaona, kubvisa iyo catalyst hakuzopa chero kuoma. Mushumiro, vakaedza kundiberekesa nokuda kwekucheka catalyst, kuchenesa uye kudzorerazve muviri. Saizvozvo, vangadai vakaramba mutengo unoenderana we "yakadaro yakaoma", uyezve, basa risingabatsiri.
