Yesani galimoto MGF ndi Toyota MR2: ndi injini pakati

Вызванный успехом Mazda MX-5, MG и Toyota познакомиться с новыми родстерами

Ndi injini yapakati ndi chipinda cha anthu awiri, MGF ndi Toyota MR2 ndi mabwenzi abwino ngati tikufuna kulandira masika ndi kukwera kwamphamvu. Koma ndani ali bwino pamakona?

Motorsport yatenga gawo lofunikira m'mbiri ya MG ndi Toyota. Kuyambira 1923, Morris Garages adalumikizidwa mosadziwika bwino ndi magalimoto amasewera ndi oyenda pamisewu. Ku Toyota, kulumikizana kumeneku kudayamba koyambirira kwa zaka za m'ma 80 ndikupambana kwamasewera kenako ndikupitilira mu Fomula 1. Chitsanzo cha kukhumba kwamasewera kumeneku ndiotsika mtengo pamsika wachiwiri wa mayendedwe a MGF ndi Toyota MR2 omwe agulitsidwa lero. m'zaka zake zoyambirira monga ofuna kusankha zapamwamba.

Kuyambira mu 1989 ndi "Mazda MX-5", "roadster boom" idagwira Rover Gulu osakonzekera - pambuyo pa kuyimitsidwa kwa MGB yopambana kwambiri, mtundu wa MG udakhala chizindikiro pamitundu yamasewera a "Austin Rover Group". Komabe, a British sanaphonye mwayi wawo ndipo adayambitsa chitukuko chatsopano. Monga yankho kwakanthawi, MG RV1992 idagunda msika mu '8. Ndi yogwirizana kwambiri ndi MGB ndipo imayendetsedwa ndi V8 ya malita anayi. Kufikira 1995, makope 2000 okha ndiwo anali kupangidwa. Kutali kokwanira, mawu ofuna woyendetsa msewu watsopano akukulirakulira.

Hydragas ndi injini yapakati

Ndipo mawu amenewo anamveka - mu 1995, Rover Group inayambitsa MGF - chitukuko choyamba chatsopano kuyambira 1962. Choyang'ana kwambiri pakuyenda bwino pamsewu - woyamba wa injini yapakatikati yopanga MG ali ndi kugawa koyenera koyenera chifukwa chakutsogolo chakutsogolo. injini ya axial-cylinder yokhala ndi zofunikira pakuwongolera masewera. Kuphatikiza pa izi ndikuyimitsidwa kwa Hydragas, komwe kwalowa m'malo mwa akasupe a Austin Allegro ndi ma dampers kuyambira 1973. Zodzikongoletsera zodzaza ndi nayitrogeni ndi zamadzimadzi zimathandiza galimoto kuyima bwino pamsewu.

Ndi mtundu wake woyamba wa injini yapakatikati, MR2 (dzina la fakitale W1), Toyota idachita bwino pamsika kale MX-5 ndi MGF isanachitike. Galimotoyi yakondweretsa madalaivala ake kuyambira 1984 - yolemera makilogalamu osachepera 1000, chassis yolimba yokhala ndi MacPherson struts kutsogolo ndi kumbuyo, ndi injini ya Corolla ya 116-cylinder yokhala ndi makamu awiri apamwamba opangidwa kuchokera ku 145 mpaka 2 hp. sinthani MRXNUMX yoyamba kukhala galimoto yodziwika bwino.

Mu 1989, okonza Toyota anamasuliranso mutu wa MR2 m'njira yatsopano - m'badwo wachiwiri unakula ndi 200 mm mpaka 4170 mm, wheelbase anatambasula ndi 80 mm, kufika mamilimita 2400. Ndipo ndi 400kg kumbuyo mapeto m'malo agility ndi sporty kupsa mtima, latsopano MR2 amaonetsa zambiri makhalidwe a GT chitsanzo kwa maulendo ataliatali, monga anatsindika anayi yamphamvu injini milingo 12 mphamvu kuchokera 133 mpaka 245 hp. Komabe, chiwerengero cha malonda chikuchepa mofulumira - ngakhale kuyimitsidwa kwa kupanga mtundu wa chitsanzo kumakambidwa. Apanso, maphunziro atsopano akufunika kuti apambane. M'malo mwa coupe kapena targa, W1999 idawonekera mu 3 ndi guru la nsalu. Ndipo oyendetsa chaka chonse amasangalala ndi hardtop yotsetsereka.

Limbanani ndi mbiri yanu yotayika

Mfundo yakuti Toyota adasankha kuti asagwiritse ntchito ndalama zambiri mu W3 ikuwonekera kuchokera ku injini zosiyanasiyana, kapena kani, kusakhalapo kwake. Pali injini imodzi yokha ya 1,8-lita yamphamvu ya 140 hp. Ndiyeno tsoka lalikulu linachitika - magetsi odziwika kuchokera ku Corolla ndi Celica anayamba kulephera kwambiri. Chodabwitsa ichi chinadziwika kuti "short block problem". Izi zimayamba ndi kuchuluka kwa mafuta komanso kuchepa kwa mphamvu ndipo nthawi zambiri zimayambitsa kuwonongeka kwakukulu kwa injini. Akatswiri amati mphete za pistoni zosalongosoka kapena zazing'ono kwambiri ndizomwe zimayambitsa. Komabe, Toyota anasonyeza kulabadira bwino kwambiri ndipo m'malo lonse yamphamvu chipika cha injini kuwonongeka.

Ndipo ndi injini ya MGF Rover, kuwonongeka sikwachilendo. Zifukwa za izi ndi kukula kochepa kwa silinda mutu gasket, khalidwe loipa la zinthu za silinda liners, komanso mavuto matenthedwe pa nthawi yaitali galimoto pa liwiro malire. Kuwonongeka kwa injini kumawononga mbiri ya oyendetsa msewu, koma osati kutchuka kwawo. Chifukwa chake ndi chosavuta - amayendetsa modabwitsa. 120 hp MGF injini yoyambira imasangalatsa ndi mawonekedwe abwino osinthika. Ngati pali nthawi yosinthika ya valve, muli ndi 25 hp. Zambiri. Pakali pano tikukwera imodzi mwa 1430 MGF Trophy 160 hp yopangidwa.

Roadster pamlingo womwewo

Ndipotu, ndalama zowonjezera mphamvu zowonjezera sikoyenera - makokedwe a 174 Nm ndi ofanana ndi injini ya 145 hp, makhalidwe amphamvu ndi osiyana pang'ono. Poyerekeza mwachindunji MR2 ndi 140 hp. sichilola kumverera kwakusowa mphamvu; injini yake, komanso okonzeka ndi variable valavu nthawi, amaona ngati wamphamvu kwambiri mpaka 3000 rpm. Ndipo pamwamba pawo, imathamanga monyinyirika - mpaka 6500 rpm, ndipo, mosasamala kanthu zamasewera ake, amamvekabe ngati Corolla.

MGF ili ndi mawonekedwe amasewera. Zowona, amafunikira ma revs ambiri kuti adzuke, koma amapitilira njira yopita kudera lofiyira ndi chikhumbo chochulukirapo ndikukusangalatsani ndi mawu okwiya kwambiri. Zomwe MR2 ndi MGF zimafanana ndizosintha molakwika, zomwe zimachitika kawirikawiri pamagalimoto apakati. Pamene ma radii akucheperachepera, kusintha kwabwino kwa Toyota kumawonekera. Chiwongolero cholondola chimagunda chandamale ndi millimeter molondola, chassis, ngakhale kuti imakhala yolimba, imakhalabe ndi chitonthozo chotsalira - kuwonjezera apo, munthu akhoza kumva ubwino wa kulemera kochepa kwa makilogalamu 115. M'malo mwake, munthu angayembekezere kuchita bwino kwambiri kuchokera ku MGF, yomwe ndi yapamwamba kwambiri ndipo imaphatikizapo kuyimitsidwa kwa Hydragas ndi chiwongolero chamagetsi. Komabe, zowongolera mphamvu zamagetsi sizikuyenda bwino - mpaka 80 km / h chiwongolerocho chimakhala ndi kumverera kochita kupanga, koma pamwamba pa liwirolo mayankho ake amakhala olunjika mosangalatsa.

MGF chassis ikuwonetsa kukhudzika kwa dongosolo la Hydragas, momwe masika ndi ma damper element, nayitrogeni ndi madzimadzi osungunuka, amasiyanitsidwa ndi nembanemba. Akapakidwa, madziwo amayenda kudzera m'mavavu kupita kumagulu odzaza mpweya, zomwe zimapangitsa kuyimitsidwa kukhala kolimba. Zinthu za Hydragas kumbali iliyonse zimapanga gawo limodzi - ngati gudumu lakutsogolo likukwezedwa, kupanikizika kumasamutsidwa kupita ku chinthu chakumbuyo kudzera pa chitoliro cholumikizira, kotero dongosololi limakhala "lodziwikiratu".

Poyerekeza ndi kuyimitsidwa kwa hydropneumatic ya Citroen, dongosolo la Hydragas ndi losavuta komanso limagwira ntchito popanda pampu yokakamiza. Ikakonzedwa bwino, yankho laukadaulo la MG ndilabwino, koma limafunikira kuyang'anira ndi kukonza nthawi zonse. The Trophy 160 chassis yapadera yosindikizira imatsitsidwa ndi 20mm, kutsimikizira kuti kuuma sikuyenera kufananizidwa ndi kugwira bwino. Kodi izi zikutanthauza kuti mtundu wa Toyota ndiye galimoto yabwino kwambiri yoyenda mtunda wautali? Ayi! Chifukwa apa ndipamene lipenga lamphamvu la MGF limayamba kusewera - kukwanira kwake pamoyo watsiku ndi tsiku komanso malo ake opatsa modabwitsa.

Matumba achitseko azinthu zazing'ono

Pachifukwa ichi, Toyota ikuyenera chifundo chimodzi - ndipo ndicho kabuku kake kamakono koperekedwa ku gawo lonse la malo azinthu zazing'ono. Palinso maumboni okhudza matumba a pakhomo ndi chipinda chamagetsi ("Tsamba laling'ono pa chida chokhala ndi chivindikiro") - pamodzi ndi thunthu pansi pa chivundikiro chakutsogolo ndi voliyumu yonse ya malita 31. Pali malita ena 60 akudikirirani kumbuyo kwa mipando, ndipo chivundikiro cha pulasitiki champhamvu pamwamba pawo chikhoza kutsekedwa.

Sizili choncho ndi MGF, yokhala ndi chipinda chogwiritsira ntchito bwino cha malita 210 kumbuyo kwa injini. Malita ena 60 amawonjezeredwa pansi pa bonnet, bola ngati mutasuntha makina oyendetsa matayala a Tire Fit kuseri kwa mpando wa driver.

Chifukwa chake ngati mukufuna kugwiritsa ntchito roadster yanu popita kutchuthi, MGF ndiye galimoto yoyenera kwambiri kwa inu. Ngati mukufunafuna galimoto yolimbitsa thupi komanso yosala pang'ono kusangalala, mupeza chisangalalo chanu ndi Toyota MR2. Ponena za mikhalidwe yothandiza, kulibe malo oti azikhala ndi injini yapakatikati.

Pomaliza

Mkonzi Kai Clouder: Zoyenda zonse zapakati ziyenera kugulitsidwa ndi mankhwala ngati machiritso amisala. Ngakhale sizowona zamagalimoto amasewera, amatha kuyenda mwamphamvu ndikukhalabe odalirika mpaka kuthamanga kwambiri. Chiwerengero cha magwiridwe antchito ndichabwino kwambiri; kuchokera ku 2500 euros ndi zina ku Germany kuli MR2 yosungidwa bwino ndi MGF. Gulani!
