Galimoto utsi zobwezedwa - zolephera, zizindikiro, utsi wosiyanasiyana kukonza

Chinthu cha injini, chomwe ndi chochuluka chotulutsa mpweya, chingawoneke chophweka, chimakhala ndi mavuto angapo. Zimadalira kapangidwe ka unit ndi zovuta zosiyanasiyana zimatha kuchitika pamitundu yamagalimoto. Mwachitsanzo, mu injini ya 1.9 TDI ya Golf V, ma gasket opopera nthawi zambiri amalekanitsidwa kuchokera pamwamba pa silinda. M'magawo akale a petulo a Opel (2.0 16V), mng'alu udawoneka pafupifupi pakati pa gawolo. Chifukwa chiyani kuchuluka kwa utsi sikukhalitsa m'magalimoto oyatsira mkati?

Chifukwa chiyani kuchuluka kwa utsi kumalephera? Zinthu zazikulu zomwe zitha kuwonongeka

Chofunikira kwambiri pakugwira ntchito kwautsi wambiri ndi machitidwe ogwirira ntchito a dongosolo lonse. Kuchita kwake kumakhudzidwa ndi:

• kutentha;
• kugwedezeka kwa injini;
• misewu;
• ntchito yamagalimoto.

Kulumikizana ndi chipika cha injini kumapangitsa kuti chinthu ichi chitenthe mpaka kutentha kwambiri. Mpweya wotulutsa mpweya womwe umadutsa mu utsi ndi wotentha kwambiri (mpaka madigiri 700 Celsius m'magawo amafuta), zomwe zimakhudza kukula kwa zinthuzo. Kuphatikiza apo, kugwedezeka kwa injini, kufalikira kwamafuta osiyanasiyana azinthu zosiyanasiyana (aluminiyamu amachita mosiyana ndi chitsulo chosungunula), mphamvu yakusintha kwakunja (chisanu, matope, madzi) ndipo, pomaliza, momwe galimoto imagwiritsidwira ntchito iyeneranso kuwonjezeredwa. . . Chifukwa chake, wokhometsa magalimoto amakhala ndi vuto lililonse mbali zonse. Kodi nthawi zambiri vuto lake ndi chiyani?

Kuchuluka kwa utsi wosweka - chifukwa chiyani izi zikuchitika?

Chikoka chachikulu pa izo wokhometsa galimoto amasweka, amakumana ndi zinthu zosiyana. Chitsulo chotayira, chomwe nthawi zambiri chimapangidwa ndi utsi wambiri, chimatentha pang'onopang'ono kuposa aluminiyamu ndi chitsulo. Choncho, makamaka poyendetsa molimba kwambiri pa injini yozizira, zikhoza kuchitika kuti chipika cha aluminiyamu chimachita mosiyana ndi chitsulo chosungunuka. Zopangira zitsulo zotulutsa zitsulo zambiri zimakhazikika bwino, zomwe sizili choncho ndi zopindika zowotcherera. Zotsatira zake, chinthucho chimasweka, monga lamulo, pamalo owotcherera.

Kuchuluka kwa utsi wosweka ndi chizindikiro cha kusweka ndi kulephera. Kodi kukonzanso kapena kukonza kumafunika liti?

Njira yosavuta yodziwira zobwezeredwa ndikungoyambitsa injini. Phokoso la ntchito yake ndi losiyana, ndipo m'magalimoto ena limakhala losiyana malinga ndi kutsika kapena kumtunda kwa rpm ndi kuchuluka kwa kutentha kwa injini. Kachitidwe kofewa kale kagawo kakang'ono komanso chete kosangalatsa m'kanyumbako kumasanduka phokoso lachitsulo chosasangalatsa. Komabe, sikudzakhala kotheka nthawi zonse kuona kumene utsi wochuluka wawonongeka. Nthawi zambiri chifukwa chake ndi ma microcracks, osawoneka popanda disassembly ndikuwunika patebulo.

Kuwotchera kotulutsa mpweya wambiri - kodi ndikoyenera?

Ngati mufunsa "munthu wodziwa" aliyense yemwe angakumane naye, adzakuuzani kuti zingatheke. Ndipo kwenikweni iye adzakhala wolondola, chifukwa wokhometsa wotayira akhoza kuphikidwa. Komabe, zotsatira za zochita zotere sizikhala zoyipa nthawi zonse (kwenikweni nthawi zambiri). Izi ndichifukwa choti chitsulo chosungunuka ndi chinthu chovuta kwambiri pakukonza. Ndizotsika mtengo komanso zolimba, koma kuwotcherera kumafuna njira zoyenera.

Kutulutsa kosiyanasiyana kapena kuwotcherera?

Panthawi imeneyi, kuwonongeka kwa zinthu za welds kumawonekera, zomwe zimawonekera pamene zimazizira. Zikawoneka kuti zonse zaphikidwa kale, mwadzidzidzi mudzamva "pop" ndipo ntchito zanu zonse zili pachabe. Kuonjezera apo, pamene kuwotcherera, wokhometsa amachepetsa kutuluka kwake, zomwe zimakhudza kwambiri ntchito ya unit. Kukonzekera kamodzi motere ndikovomerezeka, koma ndi bwino kugula gawo lachiwiri mu sitolo ya pa intaneti (ngakhale yogwiritsidwa ntchito), chifukwa mtengo udzakhala wofanana.

Nanga bwanji kuchotsa manifold exhaust?

Ngakhale manifold otopetsa ndi chitoliro chachitsulo chopangidwa ndi fakitale, chimakhudza kwambiri magwiridwe antchito a injini. Kutalika kwa wosonkhanitsa kumakhudza kwambiri ntchito, monga momwe amachitira mbiri ya mayendedwe. Kuyang'ana mwatsatanetsatane, muwona kuti nthawi ina imalumikizana ndi chitoliro chimodzi chodutsa chingwe pansi pa injini. Chofufutira cha lambda nthawi zambiri chimayikidwa mu silinda yotulutsa mpweya kuti ayeze momwe gasi wotuluka.

Tuners, nawonso, ali okonzeka kusintha dongosolo lonse la utsi, kuyambira ndi zochulukira, zomwe zimakhudza kwambiri kukwaniritsa mphamvu mumagulu osiyanasiyana a rpm (makamaka apamwamba). Kuchokera apa tikhoza kunena kuti wosonkhanitsa sangathe kutayidwa.

Zoyenera kuchita ngati pali vuto ndi kuchuluka kwa madyedwe? Zizindikiro nthawi zina zimakhala zosaoneka ndi maso, choncho ndi bwino kukaonana ndi katswiri. Zowonongeka zowonongeka m'galimoto siziyenera kukonzedwa, choncho ndi bwino ngati mutangoganiza zogula gawo latsopano lomwe galimotoyo silingathe kuchita popanda.
