Kev tshem tawm Catalyst: Pros thiab Cons

Lub catalytic converter los yog catalytic converter yog lub npe nom rau ib lub caij nyob rau hauv lub tsheb lub pa system, uas yog tsuas yog hu ua catalyst luv luv. Nws yog ntsia rau txhua lub tsheb niaj hnub nrog lub hom phiaj ntawm kev txo qis cov ntsiab lus ntawm cov teeb meem hauv cov pa tawm.

Vim li cas thiaj xav tau catalyst?

Peb txhua tus pom zoo tias tib neeg ua rau muaj kev puas tsuaj rau qhov xwm txheej. Thiab ib qho ntawm cov pa phem tseem ceeb yog cov tsheb uas tso tawm tag nrho cov kab mob thiab cov kab mob carcinogenic rau hauv cov huab cua: carbon monoxide, hydrocarbons, nitrogen oxides, thiab lwm yam. Cov pa roj no yog qhov ua rau smog thiab acid nag.

Hmoov zoo, qhov teeb meem tau pom nyob rau lub sijhawm thiab kev ntsuas tau raug coj los txo qis cov pa phem. Koj tuaj yeem tham ntev txog lub tsheb hybrid lossis lub tshuab hluav taws xob. Tab sis ib qho ntawm cov kev daws teeb meem yooj yim tshaj plaws yog txhawm rau nruab catalytic converters hauv cov pa tawm. Dhau los ntawm cov catalyst, cov tshuaj lom cov tshuaj lom neeg los ntawm ntau yam tshuaj tiv thaiv decompose rau hauv cov khoom muaj kev nyab xeeb tag nrho: dej vapor, nitrogen thiab carbon dioxide. Catalysts tau nruab rau hauv tsheb nrog ob qho tib si roj av thiab diesel xyaw. Nyob rau hauv cov ntaub ntawv ntawm cov roj diesel, nws muaj peev xwm txo tau qhov teeb meem emissions los ntawm 90 feem pua.

Txawm li cas los xij, muaj ib qho teeb meem tseem ceeb - cov cell catalyst clog sai heev thiab cov cuab yeej tsis tuaj yeem tiv nrog cov pa ntxuav. Lambda probes ntsia nyob rau hauv pem hauv ntej ntawm thiab tom qab lub catalyst ntawm lub muffler ntes ib tug siab cov ntsiab lus ntawm cov pa roj carbon dioxide nyob rau hauv lub tso pa, uas yog vim li cas lub Check Engine tas li teeb nyob rau hauv lub on-board computer.

Tsis tas li ntawd, thaum lub catalyst tau txhaws, nws cuam tshuam tsis zoo rau kev ua haujlwm ntawm lub cav:

• hwj chim txo;
• cov pa roj nkag mus rau hauv lub cav, cuam tshuam qhov kev sib xyaw ntawm cov roj-cua sib tov;
• lub load ntawm lub muffler system nce - muaj ib tug tiag tiag kev pheej hmoo ntawm nws burning tawm.

Tsuas muaj ib txoj hauv kev tawm - mus rau lub khw muag khoom lossis mus rau qhov chaw pabcuam thiab nruab ib lub catalyst tshiab. Muaj tseeb, muaj lwm txoj kev daws teeb meem. Koj tuaj yeem yooj yim tshem tawm cov catalytic converter. Environmentalists, tau kawg, tsis zoo li yuav nyiam qhov no, tab sis koj lub tsheb yuav ua haujlwm ib txwm ua dua yam tsis tas yuav teeb tsa lub catalyst tshiab.

Cov txiaj ntsig ntawm Kev tshem tawm Catalyst

Ua ntej ntawm peb lub vev xaib vodi.su peb twb tau qhia koj li cas thiab nrog dab tsi koj tuaj yeem hloov cov catalyst. Txoj kev yooj yim tshaj plaws yog nruab ib lub nplaim taws los yog snag. Cov no yog cov hlau yooj yim "cov kaus poom" uas tau nruab rau hauv qhov chaw ntawm lub converter. Ntawm tus nqi lawv pheej yig dua, feem ntau, tus neeg tsav tsheb txuag tau qee qhov nyiaj.

Yog tias peb tham txog cov txiaj ntsig tseem ceeb ntawm kev tshem tawm cov catalyst, ces tsis muaj ntau ntawm lawv li nws yuav zoo li thaum xub thawj siab ib muag:

• nce me ntsis ntawm lub cav fais fab, lus los ntawm 3-5 feem pua;
• txo roj noj - dua nyob rau hauv me me;
• nce nyob rau hauv lub cav lub neej vim lub fact tias ib tug ntxiv barrier disappears nyob rau hauv txoj kev ntawm cov pa pa gases.

Nws yog qhov tseeb tias qee tus neeg tsav tsheb tsis yog txiav tawm cov catalyst xwb, tab sis tuaj nrog qee yam los hloov nws. Piv txwv li, raws li ib feem ntawm kev kho, "Spiders" raug teeb tsa - lawv txuas ncaj qha mus rau lub cav thaiv tsis siv lub tshuab tso pa tawm thiab txuas nrog lub muffler. Lawv muab lub zog me ntsis nce mus txog kaum feem pua ​​(siv rau hauv tus account tshem tawm cov catalyst).

Cons ntawm tshem tawm catalyst

Yog tias koj saib hauv kev nthuav dav, ces qhov tsis zoo ntawm kev tshem tawm cov catalyst kuj txaus. Lub ntsiab qhov tsis zoo yog qhov nce qib ntawm cov teeb meem emissions. Qhov tseeb yog tias cov kev cai ob qho tib si hauv EU thiab hauv Lavxias Federation raug nruj nruj. Raws li koj paub, muaj ib tsab xov xwm ntawm Txoj Cai Tswjfwm Kev Ua Phem 8.23, raws li cov tswv tsheb tuaj yeem raug nplua 500 rubles rau ntau tshaj cov qauv rau kev tso tawm cov tshuaj phem. Muaj txhua yam uas yuav tsum tau ua ua ntej rau qhov tseeb tias cov qauv yuav nruj dua, thiab cov tub ceev xwm tsheb yuav saib xyuas lawv cov kev coj ua txhua qhov chaw. Kuj tseem muaj kev pheej hmoo uas koj yuav tsis raug tso cai tawm hauv lub tebchaws hauv lub tsheb yam tsis muaj catalyst.

Ntawm lwm yam shortcomings, peb nco ntsoov cov hauv qab no:

• cov tsos ntawm tus yam ntxwv, tsis hnov ​​tsw qab heev uas los ntawm cov tsheb thauj khoom xws li ZIL lossis GAZ-53;
• tus ntxhiab tsw tuaj yeem nkag mus rau hauv chav tsev;
• cov roj kub kub los ntawm cov khoom siv (t - 300 ° C) hlawv los ntawm cov hlau muffler sai dua;
• tus yam ntxwv ringing suab ntawm kev kub ceev.

Muaj ntau qhov kev ntxhov siab tso rau ntawm tag nrho cov muffler system vim lub catalyst tsis tsuas yog ntxuav cov pa, tab sis kuj txias thiab tshem tawm nws. Yog li ntawd, cov khoom siv muffler raug txo. daws qhov teeb meem no los ntawm kev txhim kho tib kab laug sab lossis cov nplaim taws.

Lwm qhov tseem ceeb: chav tswj hluav taws xob tau teeb tsa rau Euro 3, 4, 5 tus qauv. Yog li, yog tias cov ntsiab lus ntawm oxides nyob rau hauv cov pa tawm nce, lub Check Engine yuam kev yuav tshwm sim tas li. Yog li ntawd, koj yuav tsum tau nruab ib lub snag (ib qho tshwj xeeb spacer uas npog cov pa oxygen sensor los ntawm cov pa cua), los yog reflash chav tswj kom txo cov qauv toxicity.

Raws li koj tau pom, muaj ob peb cons. Thiab qhov tseem ceeb tshaj plaws ntawm lawv yog tus neeg tsav tsheb nws tus kheej thiab nws cov neeg caij tsheb yuav tsum tau nqus cov pa roj carbon monoxide thiab tshuaj lom cov neeg nyob ib puag ncig lawv. Yog li ntawd, yog tias koj txhawj xeeb tsis yog tsuas yog kev txuag nyiaj thiab nce me ntsis ntawm lub cav fais fab ntawm koj lub tsheb, tab sis kuj txog kev noj qab haus huv, ces nws yog qhov zoo dua los tsis kam tshem cov catalytic converter.

Yuav tshem tawm lossis tsis tshem cov catalyst?
