Txhim kho cov nplaim taws es tsis txhob siv cov catalyst - cov hauv paus ntsiab lus

Ntau tus tswv tsheb mus rau qhov ntev los txhim kho lawv lub tsheb kev ua tau zoo, txuas ntxiv nws txoj sia, thiab txo tus nqi tu.

Cov neeg tsav tsheb feem ntau ntsib cov lus nug: catalyst lossis nplaim taws ntes?

Txhawm rau daws qhov teeb meem no, koj yuav tsum teb cov lus nug hauv qab no:

• Dab tsi yog catalyst?
• Dab tsi yog nplaim taws ntes?
• Lawv qhov zoo thiab qhov tsis zoo yog dab tsi?

Qhov tseeb, cov neeg kho ntawm Vodi.su portal txaus siab rau cov ncauj lus no, yog li peb yuav sim txiav txim siab nws.

Lub tsheb tso tawm system: catalytic converter

Tej zaum ntau tus neeg nco qab los ntawm cov chav kawm chemistry uas lub catalyst yog ib yam khoom uas muaj ntau yam tshuaj lom neeg tshwm sim sai dua.

Lub combustion ntawm roj av tsim ntau yam khoom uas ua paug rau huab cua:

• carbon monoxide, carbon dioxide;
• hydrocarbons, uas yog ib qho ntawm cov laj thawj rau kev tsim cov yam ntxwv smog hauv cov nroog loj;
• nitrogen oxides, uas ua rau acid nag.

Dej vapor kuj tso tawm ntau heev. Tag nrho cov pa roj no maj mam ua rau lub ntiaj teb sov. Txhawm rau kom txo qis lawv cov ntsiab lus hauv cov pa tawm, lawv txiav txim siab los nruab catalysts - ib hom roj lim lim. Lawv txuas ncaj qha mus rau lub tso pa manifold, uas tau txais high-pressure tso pa gases los ntawm lub cav, thiab cov gases yog kub heev.

Nws yog qhov tseeb tias lub tshuab tso pa tuaj yeem muaj qhov sib txawv, tab sis qhov tseeb nws cov tswv yim yog raws li hauv qab no:

• kab laug sab (kua pa manifold);
• lambda sojntsuam - tshwj xeeb sensors soj ntsuam cov degree ntawm afterburning roj;
• catalyst;
• thib ob lambda sojntsuam;
• muffler.

Lub khoos phis tawj program sib piv cov kev nyeem ntawm cov sensors los ntawm thawj thiab thib ob lambda probes. Yog hais tias lawv tsis txawv, ces cov catalyst yog clogged, ces lub Check Engine teeb. Lwm cov catalyst tseem tuaj yeem ntsia tau tom qab lambda sojntsuam thib ob rau kev ua kom huv huv ntau dua.

Cov txheej txheem zoo li no yuav tsum tau ua kom cov pa tawm ua raws li cov qauv nruj ib puag ncig ntawm European Union rau CO2 cov ntsiab lus.

Cov tsheb txawv teb chaws feem ntau siv cov khoom siv hluav taws xob ceramic, lawv tau tsim rau qhov nruab nrab ntawm 100-150 txhiab mais. Sij hawm dhau mus, cov catalyst tau txhaws, thiab nws cov hlwb raug rhuav tshem, thiab cov teeb meem hauv qab no tshwm sim:

• txo cov cav fais fab, deterioration hauv dynamics;
• extraneous suab - detonation ntawm roj thiab ignition ntawm cov roj uas tau leaked rau hauv lub catalyst;
• nce noj roj thiab roj av.

Raws li, tus neeg tsav tsheb txaus siab los daws qhov teeb meem sai li sai tau, tab sis thaum nws tuaj txog ntawm lub khw muag khoom tsheb thiab saib cov nqi, cov kev xav tsis zoo tshaj plaws. Pom zoo, tsis yog txhua tus xav them los ntawm 300 txog 2500 euros rau ib qho khoom siv.

Ntxiv mus, txawm tias lub warranty npog 50-100 txhiab km, tej zaum koj yuav raug tsis kam lees nws vim yog vim li cas banal - tsis tshua muaj nqi hluav taws xob hauv tsev.

Nplaim taws ntes tsis siv cov catalyst

Lub luag haujlwm tseem ceeb uas qhov kev teeb tsa ntawm cov nplaim taws daws teeb meem:

• txo suab nrov;
• txo lub zog ntawm cov pa pa;
• txo qhov kub thiab txias.

Cov nplaim taws raug teeb tsa tsis yog thawj cov khoom siv hluav taws xob, thaum cov ntsiab lus CO2 hauv cov pa nce ntxiv - qhov no yog qhov tsis zoo ntawm nws qhov kev teeb tsa.

Kev txo suab nrov yog vim muaj ob txheej txheej vaj tsev. Nyob nruab nrab ntawm cov khaubncaws sab nraud povtseg ntawm cov hlau muaj ib tug absorbing khoom, nws yuav ua tau ntom ntom non-combustible ntxhia ntaub plaub. Cov kev xav tau ntawm cov hlau yog siab heev: cov txheej sab hauv yuav tsum tiv taus qhov kub thiab txias, txheej txheej sab nrauv yuav tsum tiv taus cov dej tsis tu ncua, av, nrog rau cov tshuaj tiv thaiv dej khov, uas peb tau sau txog ntawm Vodi.su.

Cov yeeb nkab sab hauv muaj ib qho perforated nto, vim hais tias lub zog thiab ceev ntawm cov pa pa tawm los ntawm cov pa manifold yog extinguished. Yog li, tus nplaim ntes kuj ua lub luag haujlwm ntawm resonator.

Nws yog ib qho tseem ceeb heev uas nws lub ntim sib haum rau lub ntim ntawm lub cav. Yog hais tias nws yog me me, qhov no yuav ua rau lub fact tias thaum lub cav pib thiab thaum lub throttle qhib, ib tug yam ntxwv hlau rattle yuav hnov. Tsis tas li ntawd, lub cav fais fab yuav poob qis, thiab lub tshuab tso pa nws tus kheej yuav hnav sai dua, thiab cov tsev txhab nyiaj tsuas yog hlawv tawm.

Lub puab txheej ntawm soundproofing absorbs lub kinetic zog ntawm cov gases, kom tag nrho cov pa system muaj kev vibration tsawg. Qhov no tau pom zoo hauv nws lub neej ua haujlwm.

Xaiv tus nplaim ntes

Ntawm kev muag khoom koj tuaj yeem nrhiav ntau yam khoom zoo sib xws.

Ntawm txawv teb chaws manufacturers, peb ib leeg tawm:

• Platinum, Asmet, Ferroz ua hauv tebchaws Poland;
• Marmittezara, Asso - Ltalis;
• Bosal, Walker - Belgium thiab ntau lwm tus.

Feem ntau, cov tuam txhab lees paub tsim cov nplaim taws ntes rau ib hom tsheb tshwj xeeb, txawm hais tias kuj tseem muaj thoob ntiaj teb.

Tus nqi theem yog qhia:

• catalyst nqi ntawm 5000 rubles;
• nplaim ntes - los ntawm 1500.

Nyob rau hauv txoj cai, tsis muaj dab tsi xav tsis thoob ntawm no, txij li thaum cov khoom siv catalyst yog qhov nyuaj heev, thaum cov nplaim taws muaj ob daim yeeb nkab nrog cov roj hmab tuab ntawm cov khoom siv suab nrov.

Muaj, ntawm chav kawm, pheej yig dua fakes uas hlawv sai sai, tab sis lawv tsis raug muag hauv khw muag khoom loj.

Qhov tsuas yog qhov tsis zoo yog qhov nce hauv emissions ntawm cov pa phem, tab sis nyob rau hauv Russia ib puag ncig cov qauv tsis nruj li nyob rau hauv cov teb chaws Europe los yog lub teb chaws USA.
