Hloov cov catalyst nrog cov nplaim ntes: qhov zoo thiab qhov tsis zoo

Nws tau paub ntev npaum li cas cov pa tsheb tsis zoo cuam tshuam rau lub xeev ntawm huab cua. Qee qhov txij li thaum pib xyoo 2011s, cov qauv tshuaj lom neeg rau tsheb pib pib. Txij li xyoo XNUMX, nws tau dhau los ua qhov yuav tsum tau ua kom muaj cov pa tawm nrog lub catalytic converter thiab cov lim dej.

Dab tsi yog cov lim dej, peb tau sau rau hauv ib qho ntawm cov kab lus dhau los ntawm peb lub vev xaib Vodi.su. Hais txog muaj thiab cov catalytic converter. Lub caij no ntawm cov pa tawm feem ntau hu ua ib qho catalyst lossis converter. Cov tswv tsheb feem ntau tshem tawm cov catalysts thiab cov lim dej thiab muab cov nplaim taws tso rau hauv lawv qhov chaw.

Vim li cas qhov no xav tau? Qhov zoo thiab qhov tsis zoo ntawm qhov kev hloov kho no yog dab tsi? Peb yuav sim ua tib zoo xav txog cov teeb meem no hauv cov khoom siv niaj hnub no.

Dab tsi yog catalyst?

Lub npe hais rau nws tus kheej. Qhov no yog tsim los rau neutralize cov teeb meem tshuaj sib txuas uas muaj nyob rau hauv ntau qhov ntau hauv cov pa pa. Thov nco ntsoov tias cov catalyst tsuas yog ntxuav cov pa paug ntawm cov pa phem, thiab cov hmoov av nyob hauv cov lim dej.

Lub catalyst nws tus kheej yog cov hlau tsis muaj steel, uas tau nruab tam sim tom qab lub tso pa tawm ntawm cov yeeb nkab. Hauv cov ntsiab lus, peb tuaj yeem pom cov hauv qab no:

• ceramic filling nyob rau hauv daim ntawv ntawm honeycombs;
• tshav kub-resistant gasket rau kev tiv thaiv ultra-siab kub;
• Lub active catalytic tshuaj yog non-ferrous hlau: tooj liab, npib tsib xee, kub, palladium, chromium, rhodium.

Thaum cov pa roj carbon monoxide tso rau hauv daim hlau ntawm cov hlau, lub catalyst activates cov tshuaj tiv thaiv tom qab hlawv cov khoom tsis zoo (carbon monoxide thiab nws cov tebchaw). Ntawm cov zis, peb tsuas yog tau txais cov pa roj carbon dioxide nrog cov kua qaub uas nyob hauv cov lim.

Twb tau ib qho lus piav qhia ntawm cov cuab yeej no txaus kom nkag siab tias qhov khoom no tsis pheej yig. Yog hais tias lub catalyst tuaj nyob rau hauv ib tug ntxaib vaj tse nrog ib tug particulate lim, ces tus nqi yuav ncav cuag 15-25 feem pua ​​ntawm tag nrho cov nqi ntawm lub tsheb.

Yog li qhov xaus qhia nws tus kheej. Vim li cas thiaj hloov lub catalyst mus rau lub nplaim taws? Tom qab ntawd, ob peb ntawm cov neeg ua haujlwm ncaj ncees Russians tuaj yeem them taus qhov kev yuav khoom. Yog lawm, peb txhua tus xav kom huab cua huv si thiab lub ntiaj teb sov sov tsis tuaj. Tab sis thaum rau qhov no koj yuav tsum tau txais tsawg kawg yog 50 txhiab nyiaj khwv tau los ntawm koj lub hnab ris, peb txhua tus yuav nrhiav kev xaiv pheej yig dua.

Dab tsi yog nplaim taws ntes?

Cov nplaim hluav taws kub hnyiab yog lub tank stainless hlau, sab hauv uas muaj cov rwb thaiv tsev thermal (uas kuj ua raws li suab nrov rwb thaiv tsev) thiab cov yeeb nkab perforated. Lub luag haujlwm ntawm cov nplaim taws ntes yog kom txo qhov kub ntawm cov pa taws tawm ntawm lub cav kom ntau li ntau tau thiab nqus cov suab nrov. Ntawd yog, tus nplaim ntes yog tib lub resonator, tab sis nrog kev ua haujlwm ntawm kev txo qis qhov cua kub.

Muaj peb yam tseem ceeb ntawm cov nplaim taws ntes:

• nquag;
• passive;
• tag nrho.

Cov qub yog siv feem ntau, raws li lawv nqus suab vim siv cov pob zeb hauv av basalt. Ntxiv nrog rau cov yeeb nkab perforated, ob peb diffusers ntawm ntau txoj kab uas hla yog ntsia rau hauv cov dampers passive. Qhov kub thiab ceev ntawm cov pa roj yog txo vim qhov tseeb tias lawv thaws ob peb zaug los ntawm cov phab ntsa ntawm cov diffusers. Qhov no kuj txo cov suab nrov. Zoo, cov kev xaiv sib xyaw ua ke muab ob hom ntaub ntawv.

Tsis tas li ntawd, muaj cov nplaim taws tseem ceeb (lawv tsis tau teeb tsa tam sim ntawd tom qab lub tso pa tawm, tab sis nyob rau hauv cov yeeb nkab tso tawm) thiab cov khoom siv (lawv ua haujlwm tsawg dua, txij li cov pa roj ntawm qhov kub ntawm 450 degrees nkag mus rau lawv tam sim ntawd los ntawm cov combustion chamber) .

Cov txiaj ntsig ntawm Kev Txhim Kho Nplaim Arrester Hloov Cov Catalyst

Qhov tseem ceeb tshaj ntxiv yog qhov tseeb rau txhua tus neeg uas piv cov nqi ntawm cov catalyst thiab cov nplaim taws. Yuav thiab txhim kho tom kawg yuav raug nqi 15-20 txhiab. Ntawm lwm qhov zoo, peb qhia txog:

• zog nce;
• koj tuaj yeem siv roj av nrog tus lej octane qis dua;
• tus nplaim ntes tsis tau kub heev, yog li tsis muaj kev pheej hmoo ntawm spontaneous combustion.

Vim li cas lub zog nce? Vim hais tias cov catalyst tsim ib tug dlej tsis kam nyob rau hauv txoj kev ntawm lub tso pa gases. Cov nplaim taws ntes yog xyaum ua cov yeeb nkab hollow uas cov pa roj nkag mus dawb.

Ceramic honeycomb ntawm lub catalytic converter yuav sai sai ua clogged nrog tsawg octane roj fumes. Rau cov nplaim taws, qhov no tsis yog qhov txaus ntshai, yog li koj tseem tuaj yeem txuag tau roj. Tsis tas li ntawd, koj tuaj yeem hnov ​​​​los ntawm qee tus neeg tsav tsheb vim tias hloov cov catalyst, lub cav yuav ua haujlwm tawm nws lub neej sai dua. Qhov no tsis muaj tseeb kiag li. Lub cav, ntawm qhov tsis sib xws, yog qhov zoo dua yog tias cov pa pa tawm nrawm dua.

Disadvantages

Tseem muaj downsides. Ua ntej, txhawm rau ua qhov hloov pauv, nws tsis txaus tsuas yog txiav ib qho tuaj yeem thiab txuas lwm qhov hloov. Koj kuj yuav tsum tau reflash lub tshuab hluav taws xob tswj chav tsev. Txhawm rau ua qhov no, koj yuav tsum nrhiav tus kws tshaj lij zoo, txwv tsis pub lub cev muaj zog yuav ua haujlwm nrog kev cuam tshuam loj.

Qhov thib ob, muaj kev ntshai loj heev uas sai sai hauv Russia, nrog rau hauv Tebchaws Europe, lawv tsuas yog txwv tsis pub siv tsheb ntawm tus qauv qis dua Euro-4. Nyob rau tib lub teb chaws Poland los yog lub teb chaws Yelemees, koj yuav tsis muaj peev xwm hu rau ib tug haus luam yeeb "penny". Qhov no yog qhov tshwj xeeb tshaj yog xav tau los ntawm cov tsheb thauj khoom ua haujlwm thoob ntiaj teb - lub tsheb thauj khoom tuaj yeem xa mus rau ntawm ciam teb.

Zoo, lwm qhov tsis zoo yog qhov txo qis hauv kev pabcuam lub neej ntawm tag nrho cov muffler system. Cov nplaim hluav taws tsis tuaj yeem txo qhov ceev ntawm cov pa roj ntau npaum li lub catalyst tau ua, vim qhov no, lub nra ntxiv yuav poob rau ntawm qhov tso pa tawm. Muaj tseeb, cov peev txheej yuav txo qis los ntawm 10-20 feem pua. Qhov ntawd tsis yog qhov tseemceeb.

Yog li, kev hloov ntawm cov catalyst nrog cov nplaim taws yog qhov tseeb, muaj ntau qhov zoo dua qhov tsis zoo. Tsis txhob hnov ​​qab tsuas yog tias koj lub tsheb yuav ua rau ib puag ncig puas tsuaj, thiab koj tsis zoo li yuav raug tso cai rau hauv Tebchaws Europe hauv nws.
