1JZ-GTE injini
Injini ya 1JZ-GTE mosakayikira ndi nthano, chifukwa ndi turbocharged inline-six yomwe imapereka liwiro ku Supra sevente, Mark 2 Tourer V ndi ma Toyota ena othamanga. Pakatikati pake, 1JZ-GTE ndi mtundu wa turbocharged wa 1JZ-GE wolakalaka mwachilengedwe.
M'badwo woyamba wa 1JZ-GTE unali ndi ma turbines awiri omwe adayikidwa mofananira motsatira magetsi. Ma turbine awiri, ang'onoang'ono - CT12A, poyerekeza ndi 1JZ wamba, adawonjezera mphamvu ndi 80 hp. Kuwonjezeka kwa 80 ndiyamphamvu kwa injini yama turbo sikofunikira kwambiri, makamaka mukaganizira za kuthamanga kwa 0.7 bar. Ndi zonse za peculiarities wa malamulo Japanese, amene m'zaka zimenezo analetsa kupanga magalimoto amene mphamvu kuposa 280 ndiyamphamvu. Mphamvu yayikulu ya 280 hp imatheka pa 6200 rpm ya crankshaft, mphamvu yayikulu kwambiri ya injini ya 1JZ-GTE ndi 363 NM pa 4 rpm.
Kusinthidwa 1JZ-GTE, 1996
Mu 1996, Japanese anasintha injini, kotero 1JZ-GTE vvti anaonekera. Kuphatikiza pa mfundo yakuti injini ya turbo idalandira njira yosinthira valavu, mapasa a turbo ndi chinthu chakale. M'malo mwa ma turbine awiri ofanana anayamba kukhazikitsa Japanese, koma turbine yaikulu - CT15B.
Kuphatikiza pa kusintha kwa makina osindikizira, injini yosinthidwayo inalandira chiŵerengero chapamwamba cha kuponderezedwa. Ngati injini yokhala ndi ma turbines awiri inali 8.5: 1, ndiye kuti turbine imodzi ya 1JZ-GTE ili ndi chiŵerengero cha psinjika chawonjezeka kufika 9.0: 1. Kuchuluka kwa psinjika kunalola kukulitsa torque ku 379 N.M ndikupangitsa kuti magetsi 10% akhale okwera mtengo kwambiri. Kukwera kwambiri, ngati injini ya turbocharged, kukanikiza kumapangitsa kuti pakhale mafuta abwino kwambiri. Injini ya 1JZ-GTE ikulimbikitsidwa kuti ikhale ndi petulo ndi mlingo wa octane osachepera 95, ndipo chifukwa cha khalidwe losasangalatsa la mafuta athu, ndi bwino kudzaza mafuta a 98 kuti tipewe chiopsezo cha kuphulika.
Mu 1 1996JZ-GTE njira yozizira inasinthidwa, zomwe zimachepetsa mwayi wa kutenthedwa kwa injini. Injini ya geometry siinasinthe panthawi yamakono: isanayambe kapena itatha kukonzanso, m'mimba mwake ya silinda ndi 86 mm, ndi pisitoni 71.5 mm. Geometry ya injini yotereyi, pamene kukula kwa silinda kupitirira pisitoni, kumapangitsa kuti torque ikhale yoposa mphamvu zambiri.
Ngakhale kuti mawonekedwe a 1JZ-GTE okwezedwa "papepala" apita patsogolo, turbine yamapasa imazungulira "zosangalatsa kwambiri" pa "pamwamba", pachifukwa ichi, ena mwa okonda ikukonzekera akufunafuna zisanachitike. makongoletsedwe 1JZ-GTE amapasa turbo.
Avereji mafuta a 1JZ-GTE akuti 12 malita, koma muzochitika zenizeni mowa mosavuta kumawonjezera malita 25.

Zolakwika ndi kukonza 1JZ-GTE
Eni ake a Supra amawona kuti chifukwa cha mafuta ochepa, ma pistoni amatha kukokera, zomwe zimabweretsa kutayika kwa ma cylinders. Chifukwa cha "pansi" cholimba kwambiri, kukongoletsa kumakupatsani mwayi wobwezeretsa kupsinjika kwa 12 atmospheres. Anapha midadada 1JZ-GTE, ngakhale ntchito yogwira ndi eni ambiri, si wamba, koma ngati n'koyenera, mukhoza kuyitanitsa galimoto mgwirizano. Ndi kusintha kwa nthawi yake mafuta, zomwe ziyenera kuchitidwa makilomita 7 aliwonse, chifukwa ma turbines amatsukidwa ndi mafuta a injini, 000 km amapita asanalowe m'malo mwa mphete za 1GZ-GTE. Chifukwa cha kutenthedwa, mphetezo zingafunikire kusinthidwa kale kwambiri kuposa zikwi 300. Ndi kuthamanga kwa makilomita 300, ndi bwino kuti mutengenso chisindikizo cha mafuta a crankshaft, chomwe chingayambe kutsika pa kuthamanga koteroko. Kusakhazikika kwa idling, komanso kuviika mukamakanikiza chopondapo cha gasi, kumatha kuyambitsidwa ndi sensa yolephera kuyenda kwa mpweya.
Dziwani kuti 1JZ-GTE ali chipika chitsulo chotayira osati chipika zotayidwa, amene kumawonjezera kulemera kwa galimoto, koma amapangitsa injini kukhala atengeke kutenthedwa.
Kuti muwonjezere kudalirika, injini ya 1JZ-GTE inalibe zida zowongolera matenthedwe a hydraulic compensators, chifukwa chake, chilolezo chamafuta chiyenera kusinthidwa pakadutsa 200 km.
Toyota Supra ili ndi chizindikiro cha Yamaha pa nkhani ya nthawi. Kampani ya njinga zamoto inathandizira kupanga injini. Mukhozanso kukumbukira Toyota Celica 180, Yamaha anatenga mbali yogwira pa chilengedwe cha sikisitini vavu, mkulu-liwiro injini 2.0 galimoto iyi komanso.
Galimoto ya 1JZ-GTE idayikidwa pa:
- Chaser;
- Crest;
- Mark II, Mark II Blit;
- Pamwamba pa MK III;
- Verosa;
- Wopereka;
- Korona.
Injini ya 1JZ-GTE imadziwika ndi kukula kwakukulu pakuwongolera komanso kuwonjezeka kwamagetsi. Ngakhale fakitale 280 hp, amene palokha si yaing'ono, n'zotheka kuwonjezera mphamvu 600 - 700 ndiyamphamvu m'malo ZOWONJEZERA yekha.
