Lub catalytic converter hloov cov pa phem hauv cov pa tawm mus rau cov pa phem tsawg dua siv txoj kev txo qis redox. Lub catalytic converter nyob rau hauv koj lub tsheb lub tso pa system thiab yog ib qho tseem ceeb los tswj koj lub tsheb emissions. Nws pib hlawv emissions thiab hloov mus rau hauv dej vapor thiab oxygen. Koj lub tsheb lub ntsiab emissions muaj xws li nitrogen gas, carbon dioxide (CO2), dej vapor (H2O), carbon monoxide (CO), hydrocarbons (VOC) thiab oxides ntawm nitrogen (NO thiab NO2).
Cov tsheb niaj hnub no feem ntau yog nruab nrog peb-txoj kev catalytic converter. Thawj theem ntawm lub catalytic converter yog ib tug reductive catalyst. Nyob rau theem no, rhodium thiab platinum txo nitrogen oxide emissions. Qhov thib ob theem yog oxidation catalyst. Ntawm no, cov pa roj carbon monoxide thiab hydrocarbons uas tsis tau hlawv tau rov qab los ntawm kev hlawv lawv ntawm palladium thiab platinum catalyst. Lub kaw lus tswj yog theem thib peb thiab tswj cov dej ntws ntawm cov pa tawm. Cov ntaub ntawv no yog siv los tswj cov roj txhaj tshuaj ntawm cov pa oxygen sensor. Lub sensor yuav xa cov ntaub ntawv mus rau lub cav txog pes tsawg oxygen nyob rau hauv cov pa. Yog tias muaj cov pa ntau dhau los yog tsawg dhau, lub tshuab computer tuaj yeem nce lossis txo tus nqi los ntawm kev kho cov huab cua / roj piv. Qhov no ua kom ntseeg tau tias muaj cov pa oxygen txaus hauv cov pa roj carbon monoxide kom cov oxidation catalyst tuaj yeem hlawv cov pa roj carbon monoxide thiab hydrocarbons.
Lub catalytic converter ua haujlwm ntawm qhov kub siab heev, yog li nws tsis yog qhov tsis yooj yim rau nws ua tsis tiav. Piv txwv li, misfires nyob rau hauv lub engine system tuaj yeem overheat thiab ua rau lub catalytic converter puas. Tsis tas li ntawd, cov pa tawm tuaj yeem nkag mus rau lub catalytic converter, uas ua rau lub siab rov qab thiab ua rau lub cav nres. Qhov no yuav ua rau koj lub tsheb nres thaum tsav tsheb. Lub catalytic converter tuaj yeem raug puas tsuaj vim muaj kev cuam tshuam los ntawm cov khib nyiab ntawm txoj kev. Saib rau cov cim hauv qab no uas qhia tias qhov kev hloov pauv catalytic tsis ua haujlwm:
- Kev lag luam roj tsis zoo
- Lub tsheb tsis ua haujlwm zoo, xws li nres thaum tsav tsheb lossis muaj kev ntxhov siab
- Cav misfire
- Xyuas lub cav lub teeb
- Qhov tsw ntawm cov qe lwj
Vim tias lub catalytic converter tuaj yeem ua tsis tau lossis tsis ua haujlwm dhau sijhawm, lub catalytic converter yuav tsum tau hloov.
