Vavu yotulutsa mpweya wotulutsa mpweya: ntchito, moyo wautumiki ndi mtengo

Valve ya EGR ndi play zomwe zimathandizira kuchepetsa kutulutsa koyipa m'galimoto yanu. Iyi ndi valavu yomwe imatsegula ndi kutseka kuti ilowetsenso mpweya wotulutsa mpweya mu injini ya jakisoni. Vavu ya EGR ndiyovomerezeka pamagalimoto a dizilo ndipo ikuyikidwa kwambiri pamainjini amafuta.

🚗 Kodi valavu ya gasi yotulutsa mpweya imagwira ntchito bwanji?

La vanne EGR (Exhaust Gas Recirculation) njira yochepetsera kutulutsa mpweya woipitsa mumlengalenga. Zowonadi, kuyambira 2000, European Union yakhwimitsa malamulo otulutsa mpweya (Euro 6 standard) ndikutulutsa mpweya wambiri pa kilomita imodzi.

Mwachitsanzo, mu 2009 mlingo wololedwa unali 180 mg/km, ndipo mu 2019 unali 117 mg/km. Choncho, pofuna kuchepetsa kuchuluka kwa mpweya woipitsa wopangidwa ndi magalimoto, opanga apanga valavu ya EGR.

Ntchito yake ndi yosavuta: valavu yotulutsa mpweya wotulutsa mpweya imalola konzanso gasizothamanga kuchepetsa kuchuluka kwa CO2 yotulutsidwa mumlengalenga. Chifukwa chake, 5% mpaka 35% ya mpweya wotulutsa umagwiritsidwanso ntchito ndi injini.

Mwaukadaulo, ndi basi valavu zomwe zimatulutsa kapena misampha mpweya wotulutsa mpweya kuti ubwerenso mu injini. Valavu yotulutsa mpweya wotulutsa mpweya ndiyofunika kwambiri pamagalimoto onse a dizilo chifukwa amawononga chilengedwe kwambiri, makamaka injini isanatenthe.

Ndipotu injini ya dizilo ikamathamanga kwambiri kapena siinatenthe, mpweya wina wotulutsa mpweya supsa. Nayitrogeni oxide wochulukira ndi tinthu tating'onoting'ono (mulingo) amatulutsidwa mumlengalenga.

Kuti mupewe izi ndi kuchepetsa kutulutsa kwa zowononga, magalimoto amakhala ndi valavu ya EGR, yomwe imawongoleranso mpweya wina wotulutsa mpweya mudongosolo. jakisoni.

Kenako amawotchedwanso kachiwiri ndipo amakhala ndi mpweya wochepa woipitsa. Komabe, mfundo iyi ili ndi zovuta zake: imakonda kuipitsa jekeseni pakapita nthawi. Momwemonso, valavu yotulutsa mpweya wotulutsa mpweya wokha imatha kukhala yakuda komanso yotsekeka, ndikupangitsa kuti ikhale yosagwiritsidwa ntchito.

Ngati valavu yanu ya EGR yatsekedwa pamalo otsekedwa, galimoto yanu idzaipitsa zambiri. Ngati chikakamira pamalo otseguka, dongosolo lodyera likhoza kuwonongeka ndikutsekeka. Chifukwa chake ndikofunikira kusunga bwino valavu yotulutsa mpweya wotulutsa mpweya.

🗓️ Kodi moyo wautumiki wa valve yotulutsa mpweya wotulutsa mpweya umakhala wotalika bwanji?

Moyo wautumiki wa valve yotulutsa mpweya wotulutsa mpweya umasiyanasiyana. Chifukwa chake, tikulimbikitsidwa kuti mutchule chipika chokonzekera cha wopanga. Komabe, dziwani kuti pafupifupi valve yotulutsa mpweya wotulutsa mpweya iyenera kusinthidwa. makilomita 150 aliwonse za.

Moyo wa valve yotulutsa mpweya wotulutsa mpweya umadaliranso momwe mumagwiritsira ntchito galimoto yanu. Zowonadi, ngati mungoyendetsa mtawuni, valavu yanu yotulutsa mpweya wotulutsa mpweya imatsekeka mwachangu, chifukwa ndipamene ma injini amatulutsa zowononga kwambiri komanso mpweya.

Ngati valavu yanu ya EGR yatsekedwa kapena sikugwiranso ntchito, mungakumane ndi mavuto angapo:

• Kutaya mphamvu ;
• Kuwongolera mwaukadaulo anakana ;
• Kutulutsa utsi wakuda ;
• Injini yochenjeza nyali yotulutsa mpweya anayatsa ;
• Makina Odyetsera Ng'ombe pa liwiro lotsika.

Chifukwa chake, ndikofunikira kuti inu ndi galimoto yanu muwonjezere moyo wa valavu ya EGR. Kuti tichite zimenezi, m'pofunika kuti nthawi zonse kuyendetsa pa liwiro lalikulu pa motorway. Zowonadi, injini yanu ikakwezedwa m'mwamba, imachotsa mpweya uliwonse womwe wakhazikika muutsi.

Mofananamo, kutsika amakulolani kuyeretsa bwino sikelo yonse yomwe yasonkhanitsidwa mu dongosolo. Pomaliza, pali zowonjezera zomwe zidzawonjezedwe pamafuta anu omwe amatsuka makina otulutsa komanso makamaka valavu ya EGR.

Chonde dziwani kuti valavu ya EGR yowonongeka imatha kubweretsa zovuta zaukadaulo popeza injini yonse idzatsekedwa. Choncho, nkofunika kuti musatenge vutoli mopepuka ndikulithetsa pa zizindikiro zoyamba zooneka.

💰 Kodi vavu yotulutsa mpweya wotulutsa mpweya ndi ndalama zingati?

Ngati nyali yowongolera mpweya ibwera, ndi nthawi yosintha kapena kuyeretsa valavu ya EGR. Chonde dziwani kuti mtengo wa valve EGR ndi wosiyana kwambiri: valve ya EGR imatha kusiyana kwambiri kuchokera ku galimoto imodzi kupita ku ina.

Werengani pafupifupi kuchokera ku 100 mpaka 400 euros (Labor) sinthani valavu ya EGR. Kusiyana kwa mtengo ndi chifukwa cha teknoloji ya valve yotulutsa mpweya wotulutsa mpweya komanso malo ake.

Zoonadi, pamagalimoto ena, kupeza valavu yotulutsa mpweya wotulutsa mpweya kumakhala kovuta kwambiri ndipo motero kumafuna kuchotsedwa kwa ziwalo zina zambiri kuti mupeze mwayi. Choncho musadabwe ngati mitengo imasiyana kwambiri ndi galimoto imodzi kupita ina.

Mwachitsanzo, pa Renault Clio 4, muyenera kuyembekezera pafupifupi ma euro 80 kuti alowe m'malo mwa valve yotulutsa mpweya wotulutsa mpweya, komanso pa Ford C-Max, avareji ya 350 mayuro. Mtengo wa valavu ya EGR umasiyananso kwambiri malinga ndi teknoloji yomwe imagwiritsidwa ntchito.

Zowonadi, pali mitundu yosiyanasiyana ya valve ya EGR: valavu yotulutsa mpweya wothamanga kwambiri и otsika kuthamanga mpweya mavavu recirculation mpweya. Ma valve odziwika kwambiri a EGR ndi ma valve othamanga kwambiri omwe amapanga mzere wodutsa kuchokera pamagetsi opopera kupita kumalo ochulukirapo. Kupanikizika ndikwapamwamba chifukwa valavu ya EGR ili kumunsi kwa manifold.

Mosiyana ndi izi, ma valve otsika kwambiri otulutsa mpweya wamagetsi amakhala pafupi ndi mzere wotulutsa mpweya. Kenako amabwezera mipweya ku turbocharger osati kuchulukitsidwe kolowera. Mofananamo, kuti achepetse kutentha kwa mpweya wobwerera ku injini, kaŵirikaŵiri amakhala ndi choziziritsira.

Pomaliza, ma valve a EGR ali pafupifupi chilichonse lero. Kugwiritsa ntchito mphamvu kuti muchepetse vuto lotsegula ndi kutseka valve. Mpaka zaka za m'ma 2000, ma valve anali ambiri matayala.

Dziwani kuti anthu ena amasankha kwathunthu chotsani valavu yotulutsa mpweya wotulutsa mpweya... Koma ndizoletsedwa kutero, chifukwa galimotoyo sichikukwaniritsanso miyezo ya chitetezo cha chilengedwe yokhazikitsidwa ndi wopanga. Momwemonso, simungadutse fufuzani luso ngati mwachotsa valavu yotulutsa mpweya wotulutsa mpweya.
