Peb-txoj kev catalysis.
Peb-txoj kev catalysis yog hais txog kev hloov pauv cov pa phem xws li CO, HC thiab NOx los ntawm lub tsheb tso rau hauv cov pa roj carbon dioxide, dej thiab nitrogen los ntawm oxidation thiab txo qis. Cov cab kuj ib feem ntawm peb-txoj kev catalyst yog ib qho ntawm cov khoom siv porous ceramic, uas tau nruab rau hauv cov yeeb nkab tshwj xeeb. Nws yog hu ua tus neeg nqa khoom vim nws tsis koom nrog cov tshuaj tiv thaiv catalytic nws tus kheej, tab sis npog nrog cov txheej txheem ntawm cov hlau muaj txiaj ntsig xws li platinum, rhodium, palladium thiab tsis tshua muaj ntiaj teb. Nws yog qhov tseem ceeb tshaj plaws sab nraud purification ntaus ntawv nruab rau hauv lub tsheb tso qhov system.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm peb txoj kev catalytic converter yog: thaum lub tsheb kub kub dhau los ntawm cov khoom siv purification, lub purifier nyob rau hauv peb txoj kev catalytic converter yuav txhim khu kev ua haujlwm ntawm peb cov pa roj carbon monoxide CO, hydrocarbons thiab NOx, thiab txhawb nws kom dhau mus rau qee yam oxidation-txo tshuaj lom neeg cov tshuaj tiv thaiv, uas CO oxidized tsis muaj pa roj carbon monoxide. Hydrocarbons yog oxidized rau dej (H2O) thiab carbon dioxide ntawm qhov kub thiab txias; NOx txo qis rau nitrogen thiab oxygen. Peb qhov teeb meem gases dhau los ua cov pa tsis zoo, kom lub tsheb tso tawm tuaj yeem ua kom huv. Piv txwv tias tseem muaj cov pa oxygen, qhov piv ntawm huab cua-roj yog tsim nyog.
Vim hais tias cov roj muaj leej faj, phosphorus thiab tus neeg sawv cev antiknock MMT muaj manganese, cov khoom siv tshuaj no yuav tsim cov tshuaj complexes rau ntawm qhov chaw ntawm cov pa oxygen sensor thiab hauv peb txoj kev catalytic converter nrog cov pa tso tawm tom qab combustion. Tsis tas li ntawd, vim yog tus neeg tsav tsheb tsis zoo ntawm kev tsav tsheb, lossis kev tsav tsheb mus sij hawm ntev ntawm txoj kev congested, lub cav feem ntau nyob rau hauv lub xeev tsis tiav combustion, uas yuav tsim carbon tsub zuj zuj nyob rau hauv lub oxygen sensor thiab peb-txoj kev catalytic converter. Tsis tas li ntawd, ntau qhov chaw ntawm lub teb chaws siv cov roj av ethanol, uas muaj cov nyhuv tu kom zoo, yuav ntxuav cov av hauv chav combustion tab sis tsis tuaj yeem decompose thiab hlawv, yog li nrog cov pa tawm ntawm cov pa tawm, cov av no tseem yuav tso rau ntawm qhov chaw ntawm oxygen sensor thiab peb-txoj kev catalytic converter. Nws yog vim muaj ntau yam uas tom qab lub tsheb tau tsav mus rau lub sijhawm, ntxiv rau cov pa roj carbon monoxide nyob rau hauv qhov nqus valve thiab combustion chamber, nws tseem yuav ua rau oxygen sensor thiab peb-txoj kev catalyst lom tsis ua haujlwm, peb-txoj kev catalyst thaiv thiab EGR valve thaiv los ntawm sediment thiab lwm yam tsis ua hauj lwm, ua rau lub zog tsis zoo ntawm lub cav siv hluav taws xob thiab kev ua haujlwm tsis zoo, ua rau lub zog tsis zoo.
Kev saib xyuas lub cav tsis tu ncua yog txwv rau kev saib xyuas yooj yim ntawm lub tshuab lubrication, kev siv lub cev thiab cov khoom siv roj, tab sis nws tsis tuaj yeem ua tau raws li cov kev xav tau ntawm cov tshuab niaj hnub lubrication system, kev noj qab haus huv, kev siv roj thiab cov pa tawm, tshwj xeeb tshaj yog cov kev saib xyuas ntawm emission control system. Yog li ntawd, txawm hais tias lub tsheb tau khaws cia ib txwm siv sijhawm ntev, nws yog qhov nyuaj kom tsis txhob muaj teeb meem saum toj no.
Hauv kev teb rau cov kev ua tsis tiav, kev ntsuas los ntawm kev saib xyuas cov tuam txhab feem ntau yog hloov cov pa oxygen sensors thiab peb-txoj kev catalytic converters, tab sis vim muaj teeb meem ntawm kev hloov cov nqi, kev tsis sib haum xeeb ntawm kev saib xyuas kev lag luam thiab cov neeg siv khoom txuas ntxiv mus. Tshwj xeeb, cov pa oxygen sensors thiab peb-txoj kev catalysts uas tsis tau hloov los ntawm lawv lub neej muaj txiaj ntsig feem ntau yog qhov kev tsis sib haum xeeb, thiab ntau tus neeg siv khoom txawm hais txog qhov teeb meem ntawm lub tsheb zoo.
Txhawm rau daws qhov mob taub hau no thiab nyuaj los daws qhov teeb meem ntawm cov tuam txhab tsim tsheb, cov chaw tsim khoom, chaw saib xyuas kev tswj hwm thiab kev tiv thaiv ib puag ncig, cov koom haum tshawb fawb txog kev tshawb fawb tau tshawb fawb thiab tsim cov txheej txheem tshiab ntawm lub cav niaj hnub tu txoj kev thiab thev naus laus zis rau qhov tsis xws ntawm cov tsoos cav niaj hnub tu txoj kev.
Cov ntsiab lus ntawm cov thev naus laus zis tshiab no yog: thaum ua haujlwm tsis tu ncua rau cov neeg siv khoom, ntxiv rau kev hloov cov roj thiab kev saib xyuas ntawm peb lub lim dej, kev tu thiab tu ntawm peb-txoj kev catalytic converter ntxiv. Nws cov yam ntxwv tseem ceeb yog: Organic ua ke ntawm "Lub tsheb tso pa roj tswj qhov kev tshuaj xyuas thiab kev saib xyuas cov khoom" thiab cov khoom siv lub tshuab ua haujlwm niaj hnub ua rau cov tsoos cav tsis tu ncua tsis tuaj yeem ua tau raws li cov kev xav tau ntawm niaj hnub cav txij nkawm tsis xws luag, kev daws teeb meem tsis zoo ntawm kev ua haujlwm tsis zoo ntawm emission tswj system ntawm ib puag ncig kev tiv thaiv cav yuav raug hloov mus rau kev tiv thaiv ib puag ncig kev tiv thaiv kev ua haujlwm tsis zoo.
1, yog hais tias muaj kev puas tsuaj, kub sintering, mileage ntawm ntau tshaj 200,000 kilometers, lead lom lom, tu nyhuv tsis loj.
2, xws li lub cav nyob rau hauv nruab nrab ntawm kev tu, tam sim ntawd disconnect lub cav thiab cov khoom siv txuas hose, thiab kaw qhov ntws valve. Rov pib lub cav, ua haujlwm tsis tu ncua, tuaj yeem txuas ntxiv thiab kho.
3, xyuas seb qhov sib tov sib xyaw puas tsim nyog los xyuas kom meej tias cov kua tuaj yeem nqus tau hauv cov huab cua nkag.
4, ntxuav peb qhov chaw yuav tsum tau ntxuav tom qab lub throttle, roj nozzle thiab combustion chamber.
5, thaum lub sij hawm ntxuav, lub idle ceev yuav tsum tsis txhob siab heev kom tsis txhob overheating ntawm peb-txoj kev catalytic converter.
6, tsis txhob tso cov kua ntxuav rau ntawm lub tsheb xim.
7, qhov chaw ua haujlwm deb ntawm qhov hluav taws kub, ua haujlwm zoo ntawm kev ntsuas hluav taws.
