Kusintha mavavu pa Vaz 2114: zifukwa ndi ndondomeko kukonza
Vuto lalikulu limene muyenera kusintha mavavu pa Vaz 2114-2115 magalimoto - ndi kutopa kwawo. Milandu iyi ndi yosowa, koma ikadali ndi malo. Izi zimachitika pazifukwa zosiyanasiyana:
- mafuta otsika amathiridwa mgalimoto nthawi zonse
- kuyendetsa galimoto pa PROPANE popanda kusintha kofanana ndi firmware yolamulira
- Nambala ya pulagi yowala yolakwika
- kuphulika kosalekeza kwa injini, kapena kani, zomwe zimayambitsa
- kuyendetsa pafupipafupi mothamanga kwambiri (kuvomerezeka kovomerezeka)
Zoonadi, sizinthu zonse zomwe zingakhudze kutentha kwa valve zomwe zatchulidwa pamwambapa, koma mfundo zazikuluzikulu zikuwonetsedwabe. Pali mphindi inanso yomwe idzakhala yofunikira kusintha mavavu - izi ndi ngati atapindika akakumana ndi pistoni. Koma apa - CHENJEZO! Pa injini Vaz 2114 muyezo ndi mitu 8 vavu yamphamvu, izi sizingakhale mfundo.
Koma ngati muli ndi injini ya 16-valve, yomwe imachitika ngakhale pazithunzi za fakitale mochedwa, ndiye kuti lamba wosweka amatha kubweretsa zotsatirapo zomvetsa chisoni. M'munsimu tidzakambirana m'malo mwachidule, ndi malipoti owonetsera zithunzi za kukonzanso kuchokera ku zochitika zaumwini.
Kusintha mavavu pa VAZ 2114 - chithunzi lipoti
Kotero, choyamba, padzakhala kofunikira kuchotsa mutu wa silinda, chifukwa mwinamwake sizingatheke kufika ku ma valve. Inde, choyamba vula lamba wanthawi ndi chilichonse chomwe chingatisokoneze, kuphatikiza chophimba cha valve.
Pambuyo pake, timamasula mabawuti oteteza mutu ku chipika. Pali 10 mwa iwo onse. Kutengera tsiku lotulutsa galimotoyo, idzakhala hexagon kapena mbiri ya TORX.
Maboti kumbali imodzi ali kunja, ndipo kwina, mkati mwa mutu, kotero iwo sawoneka pa chithunzi. Onsewo atachotsedwa, ndipo chilichonse chomwe chingasokoneze kugwetsa kwina, chotsani mutu wa silinda mu injini:
Ndi bwino kuchotsa camshaft pasadakhale, popeza sikoyenera kwambiri kumasula pamutu wochotsedwa. Akachotsedwa, mukhoza kuyamba kuumitsa ma valve.
Kuti muchite izi, mukufunikira chipangizo chapadera chotchedwa desiccant. Apanso, kuti mutu wa silinda ukhazikike bwino, mutha kuyiyikanso pa block, ndikusindikiza ma bolt angapo diagonally.
Sitima yapamtunda imayikidwa ndipo valavu iliyonse "imagwira ntchito" motsatira, monga momwe chithunzi chili pansipa:
Pamene akasupe a valve achotsedwa, mukhoza kuyamba kuchotsa zisindikizo za valve. Chotsatiracho chikuwonetsedwa bwino pa chithunzi pansipa.
Pambuyo pake, mutha kuchotsa valavu mosavuta kuchokera m'manja mwake wotsogolera kuchokera mkati mwa mutu.
Ma valve ena onse amachotsedwa mu dongosolo lomwelo. Mukayika ma valve atsopano, amafunikira kuyikamo. Kuti muwoneke bwino ndi njirayi, penyani kanema wa kanema, pomwe zonsezi zikuwonetsedwa.

Ndemangayi idapangidwa ndi Evgeny Travnikov, yemwe amadziwika ndi njira yake yonse ya YouTube Theory of Internal Combustion Engines:
Mukamaliza ntchito yonseyo, mutha kukhazikitsa magawo onse ochotsedwa motsatira dongosolo lagalimoto. Ponena za mtengo wa mavavu atsopano, ndi pafupifupi 1500 rubles. Ngati mumagula padera, ndiye kuti mtengo wake ndi wosavuta kudziwa pogawa ndalamazo ndi 8.
