hloov catalyst

Lub catalytic converter yog ib feem ntawm lub tso pa tawm uas hnav tawm txawm tias tom qab ob peb xyoos ntawm kev ua haujlwm thiab ib mais ntawm ntau tshaj 100 kilometers. km tuaj yeem hloov tau.

Koj yuav 10-xyoo-laus petrol VW Passat 2.0 thiab yog nws tus tswv muaj hmoo mus txog rau thaum tus kws kuaj mob hais tias koj tuaj yeem hloov cov catalyst thiab nws yuav raug nqi koj yuav luag 4000 PLN. Tsis txhob tawg, koj tuaj yeem kho koj lub tsheb rau yim zaug pheej yig dua.

Lub catalytic converter yog ib feem ntawm lub tso pa tawm uas hnav tawm txawm tias tom qab ob peb xyoos ntawm kev ua haujlwm thiab ib mais ntawm ntau tshaj 100 kilometers. km yuav hloov tau, vim nws yuav tsis muaj peev xwm purify cov pa pa kom raws li qhov yuav tsum tau ntawm cov European qauv.

Qhov no catalyst yog dab tsi?

Lub catalyst yuav rov ua dua yog tias lub cav hlawv tag nrho. Tom qab ntawd dej thiab carbon dioxide yuav tawm ntawm cov kav dej. Hmoov tsis zoo, combustion zoo meej yeej tsis ua tiav. tshwm sim, yog li ntawd, muaj teeb meem pa roj Cheebtsam xws li carbon monoxide, hydrocarbons thiab nitrogen oxides yog tsim. Cov tshuaj no muaj kev phom sij heev rau ib puag ncig thiab tib neeg, thiab lub luag haujlwm ntawm catalyst yog hloov cov khoom tsis zoo rau hauv cov khoom tsis zoo. Catalysts siv nyob rau hauv roj av cav yuav oxidation, txo, los yog redox.

Cov oxidation catalyst hloov cov pa phem carbon monoxide thiab hydrocarbons rau hauv chav dej thiab dej thiab tsis txo cov nitrogen oxides. Ntawm qhov tod tes, nitrogen oxides raug tshem tawm los ntawm kev txo cov catalyst. Tam sim no, multifunctional (redox) catalysts, tseem hu ua triple action catalysts, yog siv, uas ib txhij tshem tawm tag nrho peb yam teeb meem ntawm cov pa pa. Cov catalyst tuaj yeem tshem tawm ntau tshaj 90 feem pua. cov khoom xyaw uas tsis zoo.

Kev puas tsuaj

Muaj ob peb hom catalyst puas. Qee tus ntawm lawv tau pom meej meej, thaum lwm tus tsuas tuaj yeem pom ntawm cov khoom siv tshwj xeeb.

Mechanical puas yog yooj yim heev rau pom thiab kuaj, vim. cov catalyst yog ib qho khoom muag heev (ceramic insert). Nws feem ntau tshwm sim tias cov khoom sab hauv tuaj tawm. Tom qab ntawd thaum tsav tsheb thiab thaum ntxiv roj, muaj lub suab nrov ntawm lub cav ntawm lub cav thiab pem hauv ntej hauv pem teb. Xws li kev puas tsuaj tuaj yeem tshwm sim los ntawm kev tsoo ib qho kev cuam tshuam lossis kev tsav tsheb mus rau hauv qhov tob tob nrog lub tshuab cua kub. Lwm hom kev puas tsuaj uas feem ntau tshwm sim thaum ua haujlwm nrog cov pa roj yog qhov melting ntawm cov tub ntxhais catalyst. Koj tuaj yeem kwv yees txog qhov kev puas tsuaj no tom qab lub tshuab hluav taws xob poob qis, thiab nws tseem tuaj yeem tshwm sim vim qhov ua tiav ntawm cov pa tawm, lub cav yuav tsis tuaj yeem pib.

Yam tsawg kawg yog qhov txaus ntshai rau tus neeg tsav tsheb, tab sis qhov txaus ntshai tshaj plaws rau ib puag ncig, yog qhov hnav ib txwm siv ntawm lub catalytic converter. Tom qab ntawd tus neeg tsav tsheb tsis xav tias muaj kev hloov pauv hauv kev ua haujlwm ntawm lub cav, tsis muaj cov paib acoustic ib yam nkaus, thiab peb tsuas yog kawm txog kev puas tsuaj thaum lub sijhawm tshuaj xyuas los yog kev tshuaj xyuas txoj kev, thaum lub sij hawm muaj pes tsawg leeg ntawm cov pa roj carbon monoxide. raug kuaj. Hauv thawj kis, peb yuav tsis tau txais qhov txuas ntxiv ntawm kev tshuaj ntsuam xyuas, thiab hauv qhov thib ob, tus tub ceev xwm yuav tau txais daim ntawv pov thawj ntawm peb thiab xa peb mus kuaj zaum ob, uas yuav tsum tau hloov nrog ib qho tshiab thiaj li yuav hla.

Yuav ua li cas yuav?

Thaum xaiv cov catalyst tshiab, peb muaj ntau txoj kev xaiv los ntawm. Qhov yooj yim tshaj plaws, yooj yim tshaj plaws thiab kim tshaj plaws yog mus ntsib ib qho chaw ua haujlwm tau tso cai. Tab sis nyob ntawd, ib qho khoom siv rau lub tsheb 10 xyoo tuaj yeem raug nqi mus txog ib nrab ntawm tus nqi ntawm lub tsheb. Nws tsis yog tus neeg muag khoom uas yuav tsum tau liam rau qhov no, tab sis cov chaw tsim khoom, uas ua rau tus nqi siab. Lwm qhov kev daws teeb meem zoo dua thiab pheej yig dua yog tsim kom muaj qhov hu ua fake. Feem ntau cov chaw tsim khoom ntawm cov catalyst yog tib yam, thiab cov nqi yuav nce mus txog 70 feem pua. hauv qab no. Hmoov tsis, muaj fakes tsuas yog rau cov qauv nrov tshaj plaws. Yog li ntawd yuav ua li cas cov tswv ntawm, piv txwv li, American, Japanese los yog txawv txawv tsheb ua? Nws hloov tawm hais tias lawv tseem tuaj yeem suav cov catalysts pheej yig, vim tias lawv muaj universal catalysts ntawm lawv pov tseg, tus nqi ntawm cov kev cai ywj pheej heev. Thiab tus nqi qis yog vim muaj ntau yam zoo, txij li lawv tau tsim tsis yog rau cov qauv tsheb tshwj xeeb, tab sis rau lub cav loj. Rau cov cav me tshaj plaws txog li 1,6 litres, koj tuaj yeem yuav ib qho catalyst rau PLN 370. Rau cov loj, los ntawm 1,6 mus rau 1,9 litres, rau PLN 440 los yog PLN 550 - los ntawm 2,0 mus rau 3,0 litres. Tau kawg, kev ua haujlwm ntau dua yuav tsum tau ntxiv rau qhov nyiaj no, uas yuav suav nrog txiav cov qub thiab vuam cov tshiab rau hauv nws. qhov chaw ntawm lub catalyst. Xws li kev ua haujlwm tuaj yeem raug nqi los ntawm PLN 100 txog 300, nyob ntawm qhov chaw ntawm cov catalyst thiab qhov nyuaj ntawm kev ua haujlwm. Tab sis nws tseem yuav pheej yig dua li kev yuav cov khoom qub catalyst.

Tuning?

Ntau lub cav tuners tshem tawm cov catalytic converter kom tau ob peb lub zog ntxiv. Ua txhaum cai. Lub cav tsis muaj lub tshuab hloov catalytic muaj teeb meem ntau dua li tib lub tsev, tsim los ua haujlwm yam tsis muaj cov cuab yeej no. Tsis tas li ntawd, tshem tawm cov catalytic converter thiab txhim kho cov yeeb nkab lossis muffler hauv nws qhov chaw yuav muaj qhov cuam tshuam, piv txwv li. kom poob rau hauv kev ua haujlwm vim tias qhov ntws ntawm cov pa tawm yuav cuam tshuam.
