Renault F4RT injini
Zamkatimu
Kumayambiriro kwa zaka za m'ma 2000, akatswiri a Renault pogwiritsa ntchito F4P odziwika bwino adapanga mphamvu yatsopano yoposa yomwe idakhazikitsidwa kale.
mafotokozedwe
Injini ya F4RT idadziwika koyamba ku 2001 ku Le Bourget (France) pawonetsero yamagalimoto yamagalimoto. Kupanga magalimoto kunapitilira mpaka 2016. Kusonkhana kwa gawoli kunachitika ku Cleon Plant, kampani ya makolo ya Renault nkhawa.
Galimotoyo idapangidwa kuti ikhazikike pamagalimoto opangira okha pamapeto apamwamba komanso zida zamasewera.
F4RT ndi 2,0-lita turbocharged four-cylinder mphamvu ya petulo yokhala ndi mphamvu ya 170-250 hp. s ndi torque 250-300 Nm.
Zakhazikitsidwa pamagalimoto a Renault:
- Bwerani (2001-2003);
- Kapena Zokwanira (2002-2009);
- Malo (2002-2013);
- Laguna (2003-2013);
- Mégane (2004-2016);
- Zowoneka bwino (2004-2006).
Kuwonjezera pa zitsanzo kutchulidwa, galimoto F4RT anaikidwa pa Megane RS, koma Baibulo anakakamizika (270 HP ndi makokedwe 340-360 NM).
Silinda yachitsulo ndi chitsulo choponyedwa, osati mzere. Aluminium alloy silinda mutu wokhala ndi mavavu 16 ndi ma camshaft awiri (DOHC). Tiyenera kukumbukira kuti camshafts ndi mbali zina za CPG (pistoni, ndodo zolumikizira, crankshaft) zimalimbikitsidwa.
Wowongolera gawo pa injini yoyaka mkati anali atapita. Kuyendetsa nthawi kunakhalabe, monga m'mbuyo mwake, lamba.
Kuyika kwa turbine kumafunika kugwiritsa ntchito mafuta apamwamba kwambiri, okhala ndi octane apamwamba (AI-95 yachitsanzo choyambira, AI-98 yamasewera - Megane RS).
Ma compensators a hydraulic amachotsa kufunika kosintha pamanja chilolezo cha valve.

Kodi zosintha za F4RT 774, 776 zikutanthawuza chiyani
Panthawi yopanga, injiniyo idasinthidwa mobwerezabwereza. Maziko a galimoto anakhalabe chimodzimodzi, zosintha makamaka anakhudza ZOWONJEZERA. Mwachitsanzo, F4RT 774 ili ndi turbo iwiri.
Kusintha kwa magalimoto kunali ndi kusiyana kwakukulu muzochita zamakono.

Kudalirika, zofooka, kusakhazikika
Kudalirika
Eni magalimoto amatcha injini ya F4RT yodalirika komanso yolimba. Izi ndi Zow. Chigawo chomwe chikufunsidwa chimakhala chapakati pagawo la injini zamafuta a turbo m'kalasi mwake.
Woyendetsa galimoto wochokera mumzinda wa Serov, pofotokoza za Renault Megane, analemba kuti: "... Injini ya f4rt 874 yopangidwa ndi Renault Sport. Zodalirika kwambiri, zosavuta komanso zoyesedwa nthawi ”. Amathandizidwa mokwanira ndi mnzake waku Omsk: "... Injini imakonda kwambiri kusamveka kwake komanso kusinthasintha. Injini ya nkhawa ya Renault-Nissan, zomwezo zimayikidwa pa Nissan Sentra yatsopano, jekeseni wamafuta okha ndi wosiyana komanso kuchuluka kwamafuta kumawoneka kosiyana.. Chidule cha MaFia57 kuchokera ku Orel: “... Ndakhala ndikugwiritsa ntchito injini ya F4RT kwa zaka 8 tsopano. Mileage 245000 Km. Kwa nthawi yonse yogwira ntchito, ndimangosintha makina opangira magetsi, kenako ndikuwononga ndi kupusa kwanga. Ndinagula yakale yokhala ndi mtunda wokwana 130 ndipo ndimayendetsabe popanda mavuto”.
Tiyenera kukumbukira kuti kudalirika kwa injini kumasungidwa kokha ndi nthawi yake komanso yoyenera.
Pa ntchito, m'pofunikanso kutsatira malangizo onse opanga. Kuzinyalanyaza kumabweretsa zotsatira zosasinthika. Mwachitsanzo, kugwiritsa ntchito mafuta a AI-92, komanso mafuta otsika, sikuvomerezeka. Kuphwanya malingalirowa kudzachepetsa kwambiri moyo wagalimoto ndikuwongolera kukonzanso kwake.
Mawanga ofooka
Zoyipa zili mu injini iliyonse. Chimodzi mwa zofooka zazikulu za F4RT zakhala zolephera zamagetsi. Ma coil poyatsira ndi masensa ena (malo a crankshaft, probe lambda) amalephera makamaka nthawi zambiri. Mosayembekezereka, ECU ikhoza kubweretsa mavuto.
Chida cha turbine chimasiyanso zofunikira. Kawirikawiri, pambuyo pa makilomita 140-150 zikwi, turbocharger iyenera kusinthidwa.
Nthawi zambiri injini ikukumana ndi kuchuluka kwa mafuta. Chifukwa cha izi chikhoza kukhala kuwonongeka kwa turbine, mphete za pistoni zomata, zisindikizo za valavu. Kuphatikiza apo, ma smudges osiyanasiyana amatha kusokoneza kugwiritsa ntchito mafuta (kupyolera mu chisindikizo chamafuta a crankshaft, zisindikizo zophimba ma valve, valavu ya turbocharger bypass).
Kuthamanga kosasunthika kosagwiranso ntchito sikumabweretsa chisangalalo. Maonekedwe awo amalumikizidwa ndi kugwiritsa ntchito mafuta otsika kwambiri, zomwe zimapangitsa kutsekeka wamba kwa throttle kapena majekeseni.
Kusungika
Kukonza unit sikuyambitsa mavuto akulu. Chitsulo chachitsulo chimakulolani kunyamula masilinda mpaka kukula kofunikira. Izi zikuwonetsa kuthekera kwa kukonzanso kwathunthu kwa injini yonse yoyaka mkati.
Zida zosinthira zofunika zitha kugulidwa ku sitolo iliyonse yapadera. Chenjezo lokhalo ndikuti zigawo zoyambirira zokha ndi zazikulu ndizoyenera kugwiritsidwa ntchito pomanganso injini. Chowonadi ndi chakuti ma analogue samagwirizana nthawi zonse ndi khalidwe, makamaka achi China. Sitikulimbikitsidwa kugwiritsa ntchito zida zosinthira zomwe zagwiritsidwa ntchito pokonzanso, chifukwa ndizosatheka kudziwa moyo wawo wotsalira.
Chifukwa cha kukwera mtengo kwa zida zosinthira ndi zovuta za ntchitoyo, ndikofunikira kuwunika mwayi wogula injini ya mgwirizano. Mtengo wake wapakati ndi pafupifupi ma ruble 70.
Injini ya F4RT, yopangidwa ndi omanga injini ya Renault, imakwaniritsa zosowa zonse za oyendetsa. Ubwino waukulu ndi wodalirika komanso wokhazikika. Koma amawonekera pokhapokha ngati malingaliro a wopanga kuti agwiritse ntchito chipangizocho atsatiridwa.
