Lub kaw lus tso pa tawm ntawm txhua lub tsheb yam tsis muaj kev zam. Nws yog tag nrho cov complex ntawm qhov chaw thiab cov khoom siv los ntawm cov pa pa tawm mus. Yog hais tias peb tham txog lub Chevrolet Niva, qhov no yog ib tug resonator, catalyst, oxygen sensor, tso manifold thiab muffler. Feem ntau, txoj haujlwm ntawm txhua lub ntsiab lus yog los txo cov suab nrov lossis qhov kub thiab txias ntawm cov pa pa tawm. Tab sis hnub no peb yuav tham txog xws li ib tug nthuav dav, uas kuj purifies gases los ntawm teeb meem hlau. Nws yog ib qho catalyst. Chevrolet Niva tau nruab nrog nws los ntawm lub Hoobkas, ua tsaug uas nws ua raws li Euro-3 thiab ntau dua ib puag ncig tus qauv.

Ntse

Yog li, qhov no yog dab tsi? Qhov no yog ib tug catalytic converter, lub luag hauj lwm tseem ceeb ntawm uas yog los txo cov emission ntawm teeb meem tshuaj mus rau hauv cov huab cua. Ib tug peb-tivthaiv hom catalyst yog ntsia rau ntawm Chevrolet Niva. Nws muajlos ntawm:

• Cas.
• Nkauj thaiv.
• rwb thaiv tsev kub.

Lub ntsiab tseem ceeb ntawm Chevrolet Niva catalyst yog cov cab kuj. Nws yog tsim los ntawm tshwj xeeb, refractory ceramics. Qhov thaiv no yog ib txheej ntawm ntau yam honeycombs tsim los ua kom thaj tsam ntawm kev sib cuag nrog cov pa pa. Cov tshuaj tshwj xeeb-catalysts yog siv rau cov honeycombs. Cov no yog palladium, rhodium thiab platinum. Cov hlau no muaj peev xwm ua kom cov tshuaj lom neeg muaj zog hauv Chevrolet Niva catalyst-resonator. Yog li, cov pa phem uas dhau los ntawm cov khoom no tau hloov mus rau qhov tsis muaj oxide, nitrogen thiab carbon dioxide. Tsis tas li ntawd nco ntsoov tias lub catalyst sensor tau teeb tsa hauv lub tsev nyob. "Chevrolet Niva" yog nruab nrog qhov yooj yim tshaj plaws oxygen sensor - nws yog ib qho rau tag nrho cov khoom. Rau kev sib piv, ob lub sensors tau nruab rau niaj hnub Japanese thiab Korean tsheb.

Ntawm cov yam ntxwv ntawm cov catalyst, nws tsim nyog sau cia qhov tseeb tias lub caij ua haujlwm ntawm qhov kub ntawm 400 degrees Celsius. Yog li ntawd, thaum lub cav sov so, lub caij no tsis ua haujlwm. Tsuas yog nyob rau qhov kub thiab txias nws tuaj yeem tshem tawm txog li 90 feem pua ntawm cov khoom tsis zoo hauv cov cell ntawm cov cab kuj.

Nws nyob qhov twg?

Vim tias qhov kev ua haujlwm kub ntawm cov khoom siv ceramic yog ntau tshaj 400 degrees Celsius, Chevrolet Niva catalyst nyob tam sim ntawd tom qab lub tso pa tawm. Yog li, cov roj gases tsis muaj sij hawm kom txias thiab ua kom sov ntawm cov khoom thauj nws tus kheej. Silencer nroglub catalyst ntawm Chevrolet Niva tsis tau ntsia raws li ib qho khoom. Cov no yog ob qhov sib txawv, ib qho yog muab tso rau ntawm qhov pib ntawm qhov system, qhov thib ob yog ntawm qhov tawm heev.

Signs

Yuav ua li cas txiav txim siab tias lub ntsiab lus no tsis raug txiav txim? Nws yog tsis yooj yim sua kom txiav txim siab malfunction los ntawm mileage. Qhov nruab nrab, ntawm Chevrolet Niva, catalysts pab txog 70 txhiab kilometers. Tab sis nws yuav xav tau kev hloov sai dua. Yog li, koj yuav tsum tau coj los ntawm cov cim qhia tsis ncaj:

• Thawj cov tsos mob yog lub teeb pom kev ntawm lub cav ntawm lub ntsuas ntsuas. Nws yuav twv yuav raug hu teeb nyob rau hauv qhov kev tshwm sim ntawm ib tug malfunction ntawm lub catalytic converter. Lub sensor uas tau teeb tsa hauv lub lim dej yuav tau txais cov ntaub ntawv tsis raug, vim tias qhov yuam kev yuav tshwm sim hauv ECU.
• txo hwj chim. Yog vim li cas rau qhov no yog qhov nyuaj tshem tawm gases los ntawm lub system. Honeycombs tuaj yeem yaj, lossis tsuas yog txhaws. Yog li ntawd, gases tsis tuaj yeem khiav tawm mus rau hauv qhov chaw. Vim li ntawd, lub tsheb yuav poob lub zog thiab nrawm nrawm.
• Roj noj. Kev nce hauv kev noj yog vim muaj ntau yam. Ua ntej, ECU yuav raug coj los ntawm qhov nruab nrab qhov tseem ceeb ntawm lambda sojntsuam, uas yog vim li cas qhov sib tov yuav tsis tsim nyog lean. Thib ob, vim qhov txo qis hauv lub zog, tus neeg tsav tsheb cia li nias lub pedal nyuaj dua li niaj zaus. Qhov no nce roj noj. Raws li kev xyaum qhia, lub tshuab pib siv 10-15 feem pua ntau dua li ib txwm.

Kev hloov pauv

Yog li, yuav ua li cas yog tias tus catalytic converter tsis ua haujlwm tau kuaj pom? Koj sim tauhloov lub lim caij nrog ib qho tshiab. Nws yuav yog txoj cai los ntawm qhov pom ntawm ecology. Tab sis nyob rau hauv cov nqe lus ntawm pob nyiaj siv, kev hloov pauv yuav suav nrog cov nqi tseem ceeb. Tom qab tag nrho, ib tug tshiab catalyst ntawm ib tug Chevrolet Niva nqi ntawm 15 txhiab rubles, thiab nws tsis yog ib tug tseeb hais tias nws yuav kav 70 txhiab kilometers. Yog li, cov tswv siv rau ntau yam kev xaiv. Nov yog:

• Tshem tawm Chevrolet Niva catalyst nrog kev teeb tsa tom ntej ntawm cov nplaim taws.
• Knocking out the ceramic filler of the qub converter.

Cov yam ntxwv ntawm txhua txoj kev yog dab tsi, peb yuav xav txog hauv qab no hauv kab lus.
