Momwe mungayeretsere valavu ya EGR
Valavu ya EGR ndiye mtima wa injini yotulutsa pambuyo pothandizira. EGR ndi yachidule ya Exhaust Gas Recirculation, ndipo ndizomwe imachita. Chida chodabwitsa ichi chokonda zachilengedwe chimatsegulidwa pansi pamikhalidwe ina yogwiritsira ntchito injini ...
Valavu ya EGR ndiye mtima wa injini yotulutsa pambuyo pothandizira. EGR ndi yachidule ya Exhaust Gas Recirculation, ndipo ndizomwe imachita. Chipangizo chochititsa chidwi kwambiri choteteza chilengedwechi chimatsegula pazigawo zina za injini ndipo chimalola mpweya wotulutsa mpweya kuti ubwerenso kudzera mu injiniyo kachiwiri. Izi zimachepetsa kwambiri mpweya woipa wa nitrogen oxides (NOx), womwe umathandizira kwambiri kupanga utsi. M'nkhaniyi, mudzapeza zambiri zokhudza ntchito ya valve ya EGR, komanso momwe mungayeretsere valve ndi chifukwa chake nthawi zambiri imafunika kutsukidwa kapena kusinthidwa.
Vavu ya EGR imakhala moyo wovuta. Ndipotu, mwina ndi chimodzi mwa zigawo zovuta kwambiri za injini yamakono. Amalangidwa nthawi zonse ndi kutentha kotentha kwambiri komwe galimoto ingapange ndipo imakhala yodzaza ndi tinthu tating'ono tamafuta osayaka, omwe amadziwika kuti kaboni. Valavu ya EGR ndi yosalimba moti imatha kuyendetsedwa ndi vacuum ya injini kapena kompyuta, pamene imatha kupirira kutentha kwa mpweya wodzaza mpweya wa 1,000-degree nthawi iliyonse injini ikugwira ntchito. Tsoka ilo, pali malire pa chilichonse, kuphatikiza valavu ya EGR.
Pambuyo pazaka masauzande ambiri, kaboni imayamba kuyika ma depositi mkati mwa valavu ya EGR, kulepheretsa valavu kuti igwire ntchito yake ngati mlonda wa EGR. Ma dipoziti a kaboni awa amakulirakulirabe mpaka valavu ya EGR itasiya kugwira ntchito bwino. Izi zitha kubweretsa zovuta zosiyanasiyana zogwirira ntchito, zomwe palibe zomwe zili zofunika. Izi zikachitika, pali njira ziwiri zazikulu zothandizira: kuyeretsa valve ya EGR kapena kusintha valve ya EGR.
Gawo 1 la 2: Kuyeretsa valavu ya EGR
Zida zofunika
- Zida zoyambira zamanja (ma ratchets, sockets, pliers, screwdrivers)
- Carburetor ndi throttle cleaner
- Gasket ya scraper
- singano mphuno pliers
- Magolovesi amakono
- Magalasi otetezera
- burashi yaying'ono
Gawo 1 Chotsani zolumikizira zonse zamagetsi.. Yambani ndikuchotsa zolumikizira zamagetsi zilizonse kapena ma hoses omwe amalumikizidwa ku valavu ya EGR.
Khwerero 2: Chotsani valavu ya EGR mu injini.. Kuvuta kwa sitepeyi kumadalira mtundu wa galimoto, komanso malo ndi chikhalidwe cha valve.
Nthawi zambiri imakhala ndi ma bawuti awiri kapena anayi akuigwira pamutu wolowera, mutu wa silinda, kapena chitoliro chotulutsa mpweya. Tsegulani mabawuti awa ndikuchotsa valavu ya EGR.
Khwerero 3: Yang'anani madoko a valve kuti atseke ndi ma depositi.. Komanso fufuzani madoko lolingana pa injini palokha. Nthawi zambiri amakhala otsekedwa ndi kaboni pafupifupi mofanana ndi valavu yokha.
Ngati chatsekeka, yesani kuchotsa zidutswa zazikulu za carbon ndi pliers zapamphuno. Gwiritsani ntchito carburetor ndi throttle body cleaner kuphatikiza ndi burashi yaying'ono kuti muyeretse zotsalira zilizonse.
Khwerero 4: Yang'anani valavu ya EGR ya madipoziti.. Ngati valavu yatsekedwa, iyeretseni bwino ndi carburetor ndi chotsukira chotsuka ndi burashi yaying'ono.
Khwerero 5: Yang'anani kuwonongeka kwa kutentha. Yang'anani valavu ya EGR kuti muwone kuwonongeka komwe kumachitika chifukwa cha kutentha, zaka komanso kuchuluka kwa kaboni.
Ngati chawonongeka, chiyenera kusinthidwa.
Khwerero 6: Yeretsani gasket ya valve ya EGR.. Yeretsani malo a gasket pa valavu ya EGR ndi injini ndi chopukutira gasket.
Samalani kuti musatengere tinthu tating'ono ta gasket mu madoko a EGR kumbali ya injini.
Khwerero 7: Bwezerani ma EGR gaskets.. Chilichonse chikatsukidwa ndikuwunikiridwa, sinthani ma EGR gasket (ma) ndikuchiphatikizira ku injini kuzinthu zamafakitale.
Khwerero 8: Yang'anani Kutayikira. Yang'anani ntchito molingana ndi bukhu lautumiki wa fakitale ndikuyang'ana ngati pali vacuum kapena mpweya wotulutsa mpweya.
Gawo 2 la 2: Kusintha mavavu a EGR
Ma valve a EGR nthawi zina amatha kukhala ovuta kusintha chifukwa cha msinkhu, chikhalidwe, kapena mtundu wa galimoto yokha. Ngati mukukumana ndi vuto ndi njira zomwe zili pansipa, ndikwabwino kukaonana ndi akatswiri.
Zida zofunika
- Zida zoyambira zamanja (ma ratchets, sockets, pliers, screwdrivers)
- Gasket ya scraper
- Magolovesi amakono
- Magalasi otetezera
Khwerero 1 Chotsani zolumikizira zamagetsi kapena mapaipi.. Yambani ndikuchotsa zolumikizira zamagetsi zilizonse kapena ma hoses omwe amalumikizidwa ku valavu ya EGR.
Khwerero 2: Chotsani mabawuti oteteza valavu ya EGR ku injini.. Kawirikawiri pali awiri mpaka anayi, malingana ndi galimoto.
Khwerero 3: Chotsani zinthu za gasket pamalo okwerera. Sungani zinyalala kunja kwa doko la EGR la injini.
Khwerero 4: Ikani valavu yatsopano ya EGR ndi gasket ya valve.. Ikani valavu yatsopano ya EGR ndi valavu ya EGR ku injini kupita ku fakitale.
Khwerero 5: Lumikizaninso ma hoses kapena zolumikizira zamagetsi.
Khwerero 6: Yang'ananinso dongosolo lanu. Yang'anani ntchito molingana ndi bukhu lautumiki wa fakitale ndikuyang'ana ngati pali vacuum kapena mpweya wotulutsa mpweya.
Mavavu a EGR ndi osavuta momwe amagwirira ntchito, koma nthawi zambiri sizophweka pankhani yosintha. Ngati simuli omasuka kusintha valavu ya EGR nokha, khalani ndi makina oyenerera ngati AvtoTachki m'malo mwa valavu ya EGR.
