Yuav ua li cas yog tias koj lub tsheb muaj teeb meem tswj tsis tau cov pa tawm?

Koj lub tsheb lub emission tswj system yog qhov tseem ceeb los tswj thiab txo cov pa phem thaum tsav tsheb! Hauv tsab xov xwm no, koj yuav pom tag nrho cov ntaub ntawv koj xav paub txog emission control systems thiab yuav ua li cas thaum tsis ua haujlwm!

🚗 Emission Control System yog dab tsi?

Txhua tus paub tias ib puag ncig yog ib qho teeb meem tseem ceeb ntawm peb lub sijhawm. Yog li ntawd, cov tuam txhab lag luam tam sim no yuav tsum tau ntsib cov qauv nruj zuj zus ntxiv rau kev siv tsheb emissions.

Los ntawm 1 Lub Ib Hlis 2002 rau cov tsheb nrog roj av cav thiab txij li 1 Lub Ib Hlis 2004 rau cov tsheb nrog cov cav tov diesel, cov tuam ntxhab yuav tsum nruj me ntsis ua raws li EOBD (Anti-Pollution System) cov lus qhia, Euro III cov khoom siv.

Yog li, koj lub tsheb emission control system yog ib qho khoom siv hluav taws xob uas nyob rau hauv daim ntawv ntawm cov ncuav qab zib thiab yog li tso cai rau koj los tswj koj lub cav emissions ntawm cov pa phem thiab xyuas kom meej tias lawv tsis pub dhau tus qauv tso cai.

Cov pa phem emissions yog emissions thaum lub sij hawm combustion theem los yog thaum lub sij hawm tom qab combustion theem. Muaj ntau yam sensors rau ntsuas qhov siv ntawm cov khoom tsis huv. Ntawm no yog cov lus piav qhia ntxaws txog yuav ua li cas cov pa phem tswj kev ua haujlwm hauv ob theem no.

Txhawm rau kom txo qis cov pa phem, combustion yuav tsum ua kom zoo. Nov yog cov npe ntawm ntau yam sensors uas ua haujlwm thaum lub sij hawm combustion:

• PMH sensor : nws yog siv los xam lub cav ceev (yuav tsum tau roj ntau npaum li cas txhaj) thiab qhov nruab nrab point. Yog hais tias muaj ib qho malfunctions thaum hlawv, nws yuav muab ib tug tsis ncaj ncees lawm teeb liab. Pmh sensor tsis zoo ua rau muaj pa phem ntau ntau.
• Cua siab sensor: nws yog siv los txiav txim siab npaum li cas ntawm cov cua kos los ntawm lub cav. Raws li nrog Pmh sensor, yog tias nws tsis ua haujlwm lossis tsis ua haujlwm, nws yuav ua rau tsis zoo rau cov pa phem.
• qhov kub thiab txias sensor coolant: qhov no cia koj paub qhov kub ntawm lub cav. Yog tias qhov ntsuas kub tsis zoo, qhov sib xyaw ntawm huab cua / roj yuav tsis sib npaug thiab kev sib xyaw ua kom zoo yuav ua rau tsis zoo, uas tuaj yeem ua rau cov pa luam yeeb dub nkag mus rau hauv cov yeeb nkab.
• Oxygen sensor (tseem hu ua Kev sojntsuam Lambda): Nws nyob ntawm qhov tso pa tawm thiab saib xyuas qhov ua tau zoo ntawm lwm cov sensors los ntawm kev txiav txim siab txog qhov twg cov pa roj hlawv tau ntim nrog oxygen (theem yuav tsum tsis txhob siab dhau, txwv tsis pub qhov no yog lub cim ntawm kev tsis zoo combustion).

Thaum lub sij hawm tom qab kub hnyiab, cov pa phem uas tso tawm los ntawm cov pa tso pa tawm raug kho kom zoo tshaj plaws kom lawv muaj kev phom sij li sai tau. Nov yog cov npe ntawm cov sensors uas cuam tshuam rau tom qab hlawv:

• Oxygen sensor tom qab catalytic converter (rau tsheb nrog roj av cav) : Nws ntsuas qhov ua tau zoo ntawm cov catalyst los ntawm kev xa cov pa oxygen tom qab catalyst. Yog tias lub catalytic converter muaj qhov tsis zoo, muaj kev phom sij ntawm cov kab mob siab.
• Differential siab sensor (rau diesel xyaw): nws tso cai rau koj ntsuas thiab yog li saib xyuas lub siab hauv cov lim dej. Yog tias lub siab siab dhau lawm, lub lim yuav txhaws, thiab rov ua dua, yog tias lub siab qis dhau lawm, lub lim yuav tawg lossis tso tseg.
• EGR Cov Lus Qhia: cov pa roj carbon monoxide raug thauj mus rau lub combustion chamber los tiv thaiv kev tso tawm ntawm cov pa phem.

???? Yuav ua li cas koj thiaj paub yog hais tias lub emission tswj system yog faulty?

Txoj hauv kev zoo tshaj plaws kom paub yog tias koj lub emission control system ua haujlwm zoo yog cia siab rau lub teeb ceeb toom emissions. Nws yog daj nyob rau hauv cov xim, nrog ib tug engine daim duab.

• Yog hais tias tus tus pom tau flashing tsis tu ncua: Lub catalytic converter feem ntau yuav muaj teeb meem thiab yuav tsum tau soj ntsuam los ntawm tus kws tshaj lij kom sai li sai tau kom tsis txhob muaj kev pheej hmoo ntawm hluav taws kub lossis kev puas tsuaj loj dua.
• Yog tias lub teeb nyob rau: lub emission tswj system tsis ua hauj lwm kom zoo thiab koj lub tsheb yuav pib emissions ntau thiab phem emissions. Ib zaug ntxiv, nws raug nquahu kom sai sai mus rau lub chaw nres tsheb rau kev kuaj mob tob.
• Yog hais tias qhov taw qhia los rau thiab tawm mus: Ntawm chav kawm, tsis muaj teeb meem loj, qhov taw qhia lub teeb tsuas yog faulty. Raws li kev ceev faj txog kev nyab xeeb, nws yog qhov zoo tshaj rau lub taub hau rau koj lub chaw nres tsheb kom tsis txhob muaj kev puas tsuaj loj dua.

🔧 Yuav ua li cas yog lub emission tswj system malfunctions?

Yog tias lub teeb ceeb toom tuaj txog, nws yog lub sijhawm los xyuas cov kev tswj xyuas cov pa phem kom sai li sai tau kom tsis txhob muaj qhov tshwm sim loj dua rau kev ua haujlwm ntawm koj lub tsheb thiab, qhov tseem ceeb tshaj plaws, kom tsis txhob rov pib dua thaum kuaj xyuas.

???? Tus nqi ntawm kev tswj hwm lub emission tswj system yog dab tsi?

Yog tias koj lub cev ua haujlwm tsis zoo, koj yuav tsum mus rau lub chaw nres tsheb kom sai li sai tau rau kev tshawb fawb ntxiv ntawm koj lub tsheb. Nws yog ib qho nyuaj rau txiav txim siab tus nqi tiag tiag ntawm cov kev pabcuam no vim tias nws yuav nyob ntawm nws qhov nyuaj. Nyob ntawm seb hom kev cuam tshuam, xam los ntawm 50 mus rau 100 euros ntawm qhov zoo tshaj plaws thiab mus txog 250 euros yog tias qhov ua tsis tau zoo yog qhov nyuaj dua. Tom qab kuaj pom qhov ua haujlwm tsis zoo, nws yuav tsum tau ntxiv tus nqi ntawm qhov yuav tsum tau hloov, dua, tus nqi yuav nyob ntawm qhov chaw, uas tuaj yeem sib txawv ntawm ob peb kaum mus rau 200 euros, piv txwv li, hloov lub sensor. . ... Muaj tsawg zaus nws yuav tsim nyog los hloov lub laij lej thiab tus nqi tuaj yeem nce mus txog 2000 €.

Txhawm rau pab koj nrhiav qhov chaw nres tsheb zoo tshaj plaws los sim koj qhov kev tswj hwm emission thiab tau txais cov lus tsocai mus rau qhov ze tshaj plaws euro, nyob ntawm koj lub tsheb qauv, peb qhia koj kom siv peb cov neeg sib piv, nws ceev thiab yooj yim thiab koj yuav tsis muaj qhov tsis txaus siab xav tsis thoob thaum tso koj order....
