Dab tsi yog qhov catalyst hauv lub tsheb?
Qhov no tsis tuaj yeem pom ntawm qhov muag liab qab, tab sis nws txoj haujlwm hauv lub cav tseem ceeb heev.
Lub tsheb ua haujlwm ua tsaug rau kev ua haujlwm ntawm ntau lub ntsiab lus, thiab txhua tus ntawm lawv muaj qhov tseem ceeb, yog li peb yuav tsum ua tib zoo saib xyuas kev tiv thaiv kom ntseeg tau tias lawv ua haujlwm zoo.
Muaj cov khoom hauv lub tsheb uas tsis pom qhov muag liab qab, tab sis ua haujlwm tseem ceeb thiab tus catalyst yog ib tug ntawm lawv. Rau ntau tus neeg tsav tsheb, tsav tsheb nrog lub converter catalytic kev ua tsis tiav tsis yog ua rau muaj kev txhawj xeeb. Txawm li cas los xij, dhau sijhawm, lub tshuab hloov pauv tuaj yeem ua rau muaj kev puas tsuaj loj rau lub cav.
Yog hais tias tus catalytic converter o Catalyst clogged, nws tuaj yeem overheat thiab ua tsis tiav vim cov roj tsis tau hlawv ntau dhau mus rau hauv qhov tso pa tawm.
Cov faults no yog engine muaj feem xyuam. muaj ib los yog ntau tshaj qhov qias neeg qias neeg thiab cov pa tawm valve.
Thaum cov roj tsis tau hlawv mus txog lub converter, qhov kub thiab txias pib nce. ceramic substrate los yog qhov loj ntawm cov khoom txhawb nqa lub transducer Yuav muab tso tseg thiab thaiv ib nrab los yog tag nrho cov pa ntws.
Yog li ntawd, yog tias koj lub catalytic converter yog saturated, koj yuav tsum tsis tsuas yog kho lub tso pa system, tab sis kuj xyuas seb yog vim li cas koj lub tsheb thiaj li roj av nyoos.
Dab tsi yog qhov catalyst hauv lub tsheb?
El catalytic converter Nws yog ib feem ntawm lub reciprocating internal combustion engine thiab Wankel internal combustion engine, uas pab tswj thiab txo cov teeb meem gases tawm los ntawm lub internal combustion engine.
Nws muaj cov kab sib chaws ceramic ntawm cov kab ntev ntev coated nrog cov ntaub ntawv xws li platinum, rhodium thiab palladium, nyob rau hauv lub tso pa rau pem hauv ntej ntawm muffler.
Lub catalytic converter yog ib qho ntawm cov khoom tseem ceeb tshaj plaws rau kev tswj cov pa pa phem los ntawm kev sib tsoo hauv cov cav.
Ua li cas nws ua hauj lwm?
Muaj ntau hom catalytic converters, tab sis cov tsheb niaj hnub no tau nruab nrog peb-txoj kev catalytic converters, uas yog nyob rau hauv peb chav kawm ntawm cov pa phem uas yuav tsum tau txo (CO, HC thiab NOX). Lub converter siv ob hom catalysts, ib qho rau txo thiab ib qho rau oxidation. Ob leeg muaj cov qauv ceramic plated nrog hlau, feem ntau yog platinum, rhodium thiab palladium. Lub tswv yim tseem ceeb yog los tsim cov qauv uas nthuav tawm cov catalyst nto kom ntau li ntau tau tiv thaiv qhov ntws ntawm cov pa roj carbon monoxide, thiab tseem txo cov nqi ntawm cov catalyst xav tau, vim nws kim heev.
