EGR valve recall Nws puas tsim nyog los hloov?
Kev ua haujlwm ntawm EGR valve thiab qhov cuam tshuam ntawm kev puas tsuaj.
Lub EGR valve (Exhaust gas recirculation valve) yog ib qho tseem ceeb ntawm kev tswj cov khoom ntawm lub cav tsheb, uas tau muab tso rau hauv lub cav kom tswj tau cov pa roj recirculation rov qab mus rau hauv cov khoom noj. Thaum lub EGR valve puas lawm, nws yuav ua rau muaj teeb meem xws li tsis ruaj tsis khov ceev ceev, tsis zoo acceleration, nce roj noj, thiab tsis muaj zog. Qhov laj thawj rau kev rov qab los yog feem ntau yog vim cov khoom sab hauv ntawm EGR valve yog corroded los ntawm ntau dua cov tshuaj chlorine hauv cov roj, ua rau lub cev tsis zoo ntawm lub valve, uas tuaj yeem ua rau lub cav ua haujlwm tsis zoo, thiab qhov xwm txheej hnyav, lub tsheb tuaj yeem nres. ntawm qis ceev, ua rau muaj kev pheej hmoo ntawm kev sib tsoo.
Yog vim li cas thiab yuav tsum tau rov qab
Qhov laj thawj rau kev rov qab los yog feem ntau yog vim cov khoom sab hauv ntawm EGR valve yog corroded los ntawm ntau dua cov tshuaj chlorine hauv cov roj, ua rau lub cev tsis zoo ntawm lub valve, uas tuaj yeem ua rau lub cav ua haujlwm tsis zoo, thiab qhov xwm txheej hnyav, lub tsheb tuaj yeem nres. ntawm qis ceev, ua rau muaj kev pheej hmoo ntawm kev sib tsoo. Yog li ntawd, lub sij hawm hloov ntawm EGR valve yog ib qho kev ntsuas tseem ceeb los xyuas kom meej lub cev ua haujlwm ntawm lub cav thiab kev nyab xeeb ntawm kev tsav tsheb.
Qhov zoo thiab qhov tsis zoo ntawm kev hloov EGR valve
Hloov lub EGR valve tuaj yeem ua kom lub cav ua haujlwm ib txwm muaj, tsis txhob muaj teeb meem xws li tsis muaj zog nrawm thiab nrawm nrawm, thiab txo qis kev siv roj thiab lub zog tsis txaus. Txawm li cas los xij, kev hloov EGR valve yuav tsum muaj qee tus nqi thiab lub sijhawm, thiab tej zaum yuav tsim nyog yog tias lub tsheb tau siv ntev los yog muaj ntau mais; Txawm li cas los xij, yog tias lub tsheb siv rau lub sijhawm luv luv lossis muaj mais tsawg, koj tuaj yeem txiav txim siab txuas ntxiv siv cov khoom qub rau kev saib xyuas.
Lub egr valve yog dab tsi?
Cov pa roj recirculation valve
EGR valve yog cov pa roj recirculation valve. Nws yog ib qho khoom siv hluav taws xob sib xyaw ua ke rau ntawm lub tshuab hluav taws xob los tswj cov pa roj recirculation rov qab los rau hauv lub cev, thiab yog ib qho tseem ceeb heev thiab tseem ceeb hauv cov pa roj recirculation ntaus ntawv. cov
Lub luag haujlwm tseem ceeb ntawm EGR valve yog los tswj cov pa tso pa nkag mus rau hauv cov khoom noj khoom haus, kom qee cov pa tso pa nkag mus rau hauv cov khoom noj khoom haus kom rov ua dua tshiab. Nws feem ntau yog nyob rau sab xis ntawm qhov nkag manifold, nyob ze ntawm lub cev lub cev, thiab txiav txim siab tus nqi ntawm cov pa pa xa mus rau qhov nqus tau los ntawm qib ntawm kev qhib lub valve tswj los ntawm lub tshuab nqus tsev vacuum. Los ntawm kev coj cov pa tso pa tawm ntawm lub cav combustion mus rau cov khoom noj khoom haus los koom nrog hauv kev sib xyaw, EGR valve tuaj yeem txo qhov kub ntawm chav combustion, txhim kho lub cav ua haujlwm zoo, txhim kho qhov chaw combustion, thiab txo lub nra ntawm lub cav. Nyob rau tib lub sijhawm, nws tuaj yeem txo qhov emission ntawm cov pa roj carbon monoxide, txo cov khob, thiab ua kom lub neej ua haujlwm ntev ntawm txhua qhov khoom.
Tsis tas li ntawd, EGR li qub kuj tau muab faib ua ob hom kev tswj xyuas tshuab thiab hluav taws xob kom hloov tau raws li qhov xav tau ntawm cov cav sib txawv. Nyob rau hauv lub tshuab hluav taws xob niaj hnub tswj hwm, txhawm rau kom tswj tau qhov tseeb ntawm cov pa roj recirculation, kaw-voj tswj lub tswv yim kuj tau txais, thiab cov theem sensor tau teeb tsa ntawm EGR valve kom nkag siab txog kev ua haujlwm ntawm lub cav tiag tiag. Lub sij hawm, thiab raws li cov ntaub ntawv no, EGR valve tau hloov kho kom qhib thiab kaw, thiaj li ua tiav kev tswj xyuas qhov tseeb ntawm cov pa roj recirculation.
Lub tsheb egr valve tawg yog dab tsi nws muaj cov tsos mob?
Dab tsi yog cov tsos mob pom tseeb uas koj tuaj yeem ntsib thaum koj lub tsheb EGR valve tsis ua haujlwm?
EGR valve, cov pa roj recirculation system valve, thaum nws ua yuam kev, lub tsheb yuav tshwm sim cov lus ceeb toom. Ua ntej ntawm tag nrho cov, idling instability los yog txawm flameout yog ib tug tshwm sim, thiab lub teeb txhaum kuj yuav flash nquag kom nco ntsoov koj them sai sai rau lub engine raws li txoj cai. Qhov thib ob, vim tias EGR valve tsis ua haujlwm tuaj yeem ua rau cov pa hluav taws xob tsis zoo, lub tsheb yuav ntsib kev txaj muag ntawm kev tsis ua tiav kev tshuaj xyuas txhua xyoo.
Yog tias EGR valve qhib, qhov kev tshwm sim tseem ceeb dua: lub tsheb yuav pom cov pa luam yeeb dub thiab tsis muaj kev nrawm, thaum roj efficiency txo thiab kev siv roj nce ntxiv. Ntawm qhov tsis sib xws, yog tias EGR valve raug kaw, cov pa hluav taws xob yuav raug cuam tshuam thiab tuaj yeem ua rau tsis ua raws li cov qauv tshuaj ntsuam xyuas txhua xyoo.
Raws li rau qhov ua rau EGR valve puas, muaj ntau yam tseem ceeb: khib nyiab roj recirculation system teeb meem zoo, kev saib xyuas tsis zoo, roj tsis zoo thiab kev laus ntawm lub valve nws tus kheej. Piv txwv li, kev siv cov roj av uas tsis muaj purity los yog qhov tsis zoo ntawm cov roj ntxiv tuaj yeem dhau los ua qhov tshwm sim sai uas ua rau EGR valve tsis ua haujlwm. EGR li qub ua haujlwm ntawm qhov kub ntawm lub cav, thiab nyob rau lub sijhawm ntev, xws li lub valve chamber npog npog thiab cov nplhaib roj hmab, lawv yuav muaj hnub nyoog vim hnav.
Zuag qhia tag nrho, kev noj qab haus huv ntawm EGR valve yog qhov tseem ceeb los tswj kev ua haujlwm ntawm lub cav thiab ib puag ncig emissions, thaum pom cov tsos mob saum toj no, kev saib xyuas yuav tsum tau nrhiav kom sai li sai tau los xyuas kom meej tias kev nyab xeeb ntawm kev tsav tsheb thiab ib puag ncig yuav tsum tau ua.
