ziziyenda ambiri amakhulupirira kuti vavu EGR m'pofunika zimitsani. Koma ena amakhulupirira kuti si ofunika zisamakuchitikireni. Tiyeni kumvetsa kuti zimene tingati dongosolo.
recirculation (EGR) nthawi zambiri amalephera ndipo amachititsa Kusakhazikika mu ntchito injini pa zachabe. Nthawi zina, chifukwa kulakwitsa makina akhoza kungoyankha 'kudzukanso' pa magetsi magalimoto. Mwachibadwa, palibe chimwemwe mavuto ngati amenewa si kupulumutsa. Ndipo si onse mbuye angachite ndi tsoka. Ambiri ntchito "kuona" zolakwa muyezo pamene injini troit, jerks kapena osayamba. Kuwonongeka kwa USR - zovuta kuthetsa vuto masquerade monga Misfire kapena "kuyesezera" nthenda suction mpweya. injini akhoza bwinobwino kuti ali woyamba ndi ntchito bwino, koma posakhalitsa nkhaniyo kusokoneza zachilendo. Choncho, matenda a kuwonongeka kwa dongosolo n'kovuta. Inde, ndipo aliyense shopu ali zipangizo kuyesa USR.
ndi USR ndi chiyani?
Primordial cholinga chake - kuteteza chilengedwe. Part wa utsi mpweya imatsogoleredwa kwa zonenepa kachitidwe nozzles, potero kuchepetsa kuyaka kutentha ndi moyenera, kuchuluka kwa CO2. Koma onse ndi opanda ungwiro, "Achilles chidendene" a dongosolo lino zazikulu - EGR valavu. Ambiri amakhulupirira kuti mfundo imeneyi si zofunika, koma nthawi zonse mafunso "ubongo" za makina kusintha dongosolo jekeseni. Kotero ngati inu chabe kuthimitsa akayakaya ndi mfundo imeneyi, tripcomputer amazunza madandaulo a zolakwa injini kulamulira. Komanso, ntchito injini adzakhala kusintha amasonyeza "vuto" Izi zidzapangitsa ndi kuwonjezeka mu mafuta dizilo, achepe mphamvu ndi ena "zithumwa". Koma pali options pano. Mu magalimoto ena kulamulira kumachitika kudzera ndi valavu solenoid ndi EGR zingalowe kwa zakudya zobwezedwa, ndi zina - pamaziko a kutentha kwa sensa coolant ndi masensa zina.
Zizindikiro vavu kulephera
Kawirikawiri chimaonetsera kugwedezeka pamene kusuntha pa liwiro otsika. Akhoza kutaya mphamvu ndi kuonjezera ndalama. Koma yodalirika chizindikiro - zolakwa kake.
Kodi ndi chifukwa mumatha zimitsani valavu USR?
Poyamba, cholinga. Othinana vavu kuti mwaye ndi utsi mpweya si ikuyenda kubwerera posungira. Chifukwa, zonenepa yaitali mpweya koyera umaperekedwa, ndi mafuta watentha bwino. Ambiri chigamulo chimene ayenera kulalikira vavu EGR pambuyo angapo ngayaye ake. Kawirikawiri omenyana chilengedwe monga kochepa kuyang'ana angapo zina si zosangalatsa chinthu chotsatira valavu kuti mukumvetsa zimene iwo sakufuna iyo inawuluka kubwerera zakudya zobwezedwa.
Kutseka vavu EGR, chithunzi kuti si mmaso, m'pofunika unscrew ndi zomangira ndi kupeza PAD ndi. Komanso, kuchokera chinsalu cha kagawo zitsulo akusowekapo mawonekedwe gasket watsopano, amene adzakhala awiri okha bawuti mabowo. Tsopano kuika ziyangoyango awiri mu malo. Mukhozanso kusagwirizana zingalowe payipi.
galimoto eni ambiri amanena kuti pambuyo zochita Turbo kwanthawi Mwamsanga, kusiya utsi pansi mathamangitsidwe zovuta, phiri ndipo imathamanga apamwamba, mphamvu bwino ndi kuchuluka kwa mtima positive.
