Nthawi ya UAZ Patriot

Mpaka posachedwapa, pa galimoto anaika onse injini ZMZ-40906 ndi ZMZ-51432 injini dizilo. Mu Okutobala 2016, wopanga adalengeza kuti chifukwa cha kuchepa kwa mtundu wa dizilo, injini yamafuta ya ZMZ-40906 yokha (Euro-4, 2,7 l, 128 hp) ndiyokhalabe mu fakitale.

Mawonekedwe a makina ogawa gasi UAZ Patriot

Injini za UAZ Patriot nthawi zambiri zimakhala ndi nthawi. Injini ya ZMZ-40906 ndi fakitale yokhala ndi maunyolo amasamba amizere iwiri. Mtundu uwu wa unyolo wanthawi, poyerekeza ndi unyolo wa mzere umodzi kapena mizere iwiri yolumikizira yomwe idagwiritsidwa ntchito kale pa injini za UAZ, simaganiziridwa kuti ndiyodalirika kwambiri ndipo nthawi zambiri imafunikira kusinthidwa pambuyo pa mtunda wa makilomita pafupifupi 100. Poyendetsa galimoto, makamaka pansi pa katundu wochulukira, maunyolo a nthawi amatha ndi kutambasula. Chizindikiro chachikulu kuti ndi nthawi yoti musinthe maunyolo atsopano ndi phokoso lachilendo lachitsulo pansi pa hood ("rattling" ya maunyolo), omwe amatsagana ndi kutayika kwa injini pa liwiro lochepa.



Chinthu china chosasangalatsa cha maunyolo a masamba ndi chakuti pamene unyolo wamasulidwa, kupuma kosayembekezereka kungachitike. Pambuyo pake, kukonza kwakukulu sikungapewedwe, choncho, ngati vuto la nthawi likupezeka, liyenera kusinthidwa nthawi yomweyo. Posintha unyolo wanthawi ndi UAZ Patriot, akatswiri amalimbikitsa kukhazikitsa unyolo wodalirika wodzigudubuza, womwe umakhala ndi moyo wautali wautumiki ndikuchenjeza kuvala nthawi yayitali kusanachitike ngozi yeniyeni ya kutha kwa unyolo.

Kukonzekera kusintha nthawi

Kukhalapo kwa maunyolo awiri mu makina ogawa gasi - kumtunda ndi kumunsi - kumapangitsa kuti ntchito yokonza njira yogawa gasi ikhale yovuta kwambiri. Mutha kusintha lamba wa nthawi ya UAZ Patriot ndi manja anu ngati muli ndi sitolo yokonza ndi luso lamakina.

Kwa ntchito muyenera:

• Zida zosinthira zida zosinthira: ma levers, ma sprockets, maunyolo, zoziziritsa kukhosi, ma gaskets.
• Threadlocker ndi seam sealer
• Mafuta ena amoto

Zida zofunika:

• Allen key 6mm
• Mafungulo (kuyambira 10 mpaka 17)
• Mkanda ndi mitu ya 12, 13, 14
• Hammer, screwdriver, chisel
• Chida chokhazikitsa camshaft
• Chalk (antifreeze drain pan, jack, puller, etc.)

Musanalowe m'malo, yikani galimotoyo kuti muthe kupeza chipinda cha injini kuchokera kumbali zonse, kuphatikizapo pansi. Zimitsani choyatsira ndikuchotsa waya "negative" kuchokera pa batire.

Kuti apeze mwachindunji kugawa gasi limagwirira ZMZ-409 injini, choyamba muyenera dismantle mfundo zingapo ili pa injini kapena pafupi.

Choyamba, muyenera kukhetsa mafuta a injini ndi antifreeze muzotengera zoyenera, kenako mutha kuchotsa radiator. Pang'ono pang'ono masulani mabawuti a poto yamafuta kapena sungunulani poto; izi zithandizanso kukhazikitsa njira yogawa gasi. Chotsatira, chotsani lamba woyendetsa pampu yoyendetsera mphamvu, ndikuchotsanso pulley ya fan. Kenako, chotsani lamba woyendetsa ku jenereta ndi mpope wamadzi (pampu). Pambuyo podula payipi yoperekera pampopu, ndikofunikira kuchotsa chivundikiro chamutu cha silinda. Lumikizani zingwe zamagetsi apamwamba, masulani zomangira zinayi ndikuchotsa chivundikiro cha kutsogolo kwa silinda limodzi ndi fani. Kenako, kumasula mabawutu atatuwo, chokani mpope. Chotsani sensa ya crankshaft pazitsulo zake mu cylinder block pomasula bolt yomwe imayiteteza. Chotsani crankshaft pulley. Amakanika odziwa bwino amalangiza kuthamangitsa injini.

Njira yothetsera nthawi

Kenako pitirizani kuchotsa mbali za choperekacho. Kuti mudziwe malo a nthawi ndi nthawi ya injini, gwiritsani ntchito chithunzi cha nthawi ya injini ya ZMZ-409.



Chotsani magiya 12 ndi 14 kuchokera ku camshaft flanges pogwiritsa ntchito chokoka chapadera. Mutamasula ma bolts, chotsani cholozera chapakati chapakati 16. Magiya 5 ndi 6 amakhazikika pa shaft yapakatikati ndi mabawuti awiri ndi loko mbale. Masulani mabawuti popinda m'mphepete mwa mbale ndikuletsa shaft kuti isatembenuke ndi screwdriver kudzera pabowo la giya 5. Chotsani zida 6 kuchokera ku shaft pogwiritsa ntchito chisel ngati chowongolera. Chotsani zida pamodzi ndi unyolo 9. Chotsani zida 5 kuchokera ku shaft, chotsani ndi unyolo 4. Kuti muchotse zida 1 pa crankshaft, choyamba chotsani dzanja ndikuchotsa O-ring. Pambuyo pake, mukhoza kukanikiza gear. Magiya 5 ndi 6 amamangiriridwa ku shaft yapakatikati yokhala ndi mabawuti awiri ndi mbale yotsekera. Masulani mabawuti popinda m'mphepete mwa mbale ndikuletsa shaft kuti isatembenuke ndi screwdriver kudzera pabowo la giya 5. Chotsani zida 6 kuchokera ku shaft pogwiritsa ntchito chisel ngati chowongolera. Chotsani zida pamodzi ndi unyolo 9. Chotsani zida 5 kuchokera ku shaft, chotsani ndi unyolo 4. Kuti muchotse zida 1 pa crankshaft, choyamba chotsani dzanja ndikuchotsa O-ring. Pambuyo pake, mukhoza kukanikiza gear. Kuti muchotse zida 1 ku crankshaft, choyamba chotsani chitsamba ndikuchotsa O-ring. Pambuyo pake, mukhoza kukanikiza gear.

Msonkhano wa nthawi

Pambuyo pa kutha kwa nthawi yomaliza, zida zonse zotha nthawi ziyenera kusinthidwa ndi zatsopano. Musanayike unyolo ndi zida ziyenera kuthandizidwa ndi mafuta a injini. Posonkhanitsa, chidwi chachikulu chiyenera kuperekedwa pakuyika kolondola kwa magiya a nthawi, chifukwa kuyendetsa bwino kwa injini kumadalira izi. Ngati zida 1 zidachotsedwa pa crankshaft, ndiye kuti ziyenera kukanikizidwanso, kenaka muvale mphete yosindikiza ndikuyika bushing. Ikani crankshaft kuti zizindikiro pa giya ndi M2 pa silinda block machesi. Ndi malo olondola a crankshaft, pisitoni ya silinda yoyamba itenga malo apakati akufa (TDC). Gwirizanitsani chotsitsa chotsitsa chotsitsa 17 pomwe simukulimbitsa zomangira. Phatikizani unyolo 4 pa sprocket 1, kenaka ikani sprocket 5 mu unyolo.

Dulani tcheni chapamwamba pa dzenje la mutu wa silinda ndikuchita zida 6. Kenako ikani zida 14 mu unyolo. Tsegulani zida 14 pa camshaft yotulutsa mpweya. Kuti muchite izi, shaft iyenera kutembenuzidwa kaye pang'onopang'ono. Mukaonetsetsa kuti pini 11 yalowa mu dzenje la gear, ikonzeni ndi bawuti. Tsopano tembenuzirani camshaft kumbali ina mpaka chizindikiro cha gear chikugwirizana ndi pamwamba pa mutu wa silinda 15. Zida zotsalira ziyenera kukhala zokhazikika. Kuyika unyolo pa gear 10, konzani chimodzimodzi. Sinthani kugwedezeka kwa unyolo mwa kukhazikitsa zothira madzi 15 ndi 16. Ikani ndikuteteza chivundikiro cha unyolo. Musanakhazikitse, gwiritsani ntchito chosindikizira chochepa kwambiri m'mphepete mwa chivundikiro cha unyolo.

Kenako phatikizani pulley ku crankshaft. Limbitsani bawuti yokwezera kapuli posamutsa giya lachisanu ndikuyika mabuleki oimika magalimoto. Kenako tembenuzirani crankshaft ndi dzanja mpaka pisitoni ya silinda yoyamba ifika pamalo a TDC. Apanso fufuzani zangochitika mwangozi zizindikiro pa magiya (1, 5, 12 ndi 14) ndi pa yamphamvu chipika. Bwezerani chivundikiro chamutu cha silinda yakutsogolo.

Kutha kwa msonkhano

Mukayika mbali zonse zanthawi ndi chivundikiro chamutu cha silinda, zimatsalirabe kuyika zida zomwe zidachotsedwa kale: sensa ya crankshaft, pampu, lamba wa alternator, lamba wowongolera mphamvu, pulley ya fan, poto yamafuta ndi radiator. Mukamaliza kusonkhanitsa, lembani mafuta ndi antifreeze. Lumikizani zingwe zamagetsi apamwamba ndikulumikiza chingwe cha "negative" ku terminal ya batri.
