Injin 1JZ-GTE
Injin 1JZ-GTE babu shakka almara ne, domin wannan turbocharged inline-six ne ke ba da gudu ga Supra na saba'in, Mark 2 Tourer V da sauran Toyotas masu sauri. A ainihin sa, 1JZ-GTE sigar turbocharged ce ta 1JZ-GE da ake so ta zahiri.
Na farko ƙarni na 1JZ-GTE aka sanye take da biyu turbines sanya a layi daya tare da wutar lantarki. Biyu, ƙananan ƙananan turbines - CT12A, idan aka kwatanta da 1JZ na yau da kullum, ya karu da 80 hp. Ƙarfafa ƙarfin dawakai 80 don injin turbo na tagwaye ba shi da mahimmanci, musamman idan aka yi la'akari da ƙarfin haɓakar mashaya 0.7. Yana da duk game da peculiarities na Japan dokokin, wanda a cikin wadannan shekaru hana kera motoci da ikon zai wuce 280 horsepower. Matsakaicin ikon 280 hp ana samunsa a 6200 rpm na crankshaft, matsakaicin ƙarfin juzu'i na injin 1JZ-GTE shine 363 N.M a 4 rpm.
An sabunta ta 1JZ-GTE, 1996
A shekara ta 1996, Jafananci sun sabunta injin, don haka 1JZ-GTE vvti ya bayyana. Bugu da ƙari, cewa injin turbo ya sami tsarin lokaci mai canzawa, turbo tagwaye abu ne na baya. Jafananci maimakon injin turbin guda biyu sun fara girka ɗaya, amma turbine mafi girma - CT15B.
Baya ga canje-canje a cikin tsarin matsi, injin da aka sabunta ya sami rabon matsawa mafi girma. Idan a kan injuna tare da turbines guda biyu ya kasance 8.5: 1, to, turbine guda 1JZ-GTE yana da ƙimar matsawa zuwa 9.0: 1. Matsakaicin karuwar matsawa ya ba da damar ƙara ƙarfin wutar lantarki zuwa 379 N.M kuma ya sa wutar lantarki ta 10% ta fi tattalin arziki. Yayi tsayi sosai, amma ga injin turbocharged, matsawa yana yin babban buƙatu akan ingancin mai. An ba da shawarar cewa injin 1JZ-GTE ya kasance mai ƙarfi da mai tare da ƙimar octane aƙalla 95, kuma idan aka yi la'akari da ƙarancin ingancin man namu, yana da kyau a cika man fetur na 98 don guje wa haɗarin fashewa.
A cikin 1 1996JZ-GTE, an canza tashoshi masu sanyaya, wanda ya rage yiwuwar yawan zafin jiki na injin. Injin lissafi ba ya canza a lokacin zamani: da kafin da kuma bayan restyling da Silinda diamita ne 86 mm, da fistan bugun jini - 71.5 mm. Irin wannan geometry na injin, lokacin da diamita na Silinda ya wuce bugun fistan, yana haifar da fifikon juzu'i akan matsakaicin iko.
Duk da cewa halayen 1JZ-GTE da aka haɓaka "a kan takarda" sun inganta, tagwayen turbine wanda ke jujjuya "mafi jin daɗi" a "saman", saboda wannan dalili, wasu masu sha'awar kunnawa suna neman pre- salo 1JZ-GTE twin turbo.
Matsakaicin yawan amfani da man fetur na 1JZ-GTE an bayyana shi a lita 12, amma a cikin yanayi na ainihi, sauƙin amfani yana ƙaruwa zuwa lita 25.

Laifi da kulawa 1JZ-GTE
Masu mallakar Supra sun lura cewa saboda ƙarancin man fetur, pistons na iya yin coke, wanda ke haifar da asarar matsawa a cikin silinda. Godiya ga "kasa" mai ƙarfi sosai, yin ado yana ba ku damar dawo da matsawa zuwa ƙimar yanayi 12. Kashe 1JZ-GTE tubalan, duk da aiki mai aiki da yawancin masu mallakar ba su da yawa, amma idan ya cancanta, zaku iya yin odar motar kwangila. Tare da canjin mai a kan lokaci, wanda ya kamata a yi kowane kilomita 7, saboda ana wanke turbines da man inji, kilomita 000 kafin a maye gurbin zoben 1GZ-GTE. Saboda zafi mai zafi, zobe na iya buƙatar maye gurbin da yawa a baya fiye da dubu 300. Tare da gudu na kilomita 300, yana da kyau a maye gurbin hatimin man fetur na crankshaft, wanda zai iya fara zub da jini a irin wannan gudu. Rashin kwanciyar hankali, da tsomawa yayin danna fedar gas, na iya haifar da gazawar firikwensin iska.
Shi ne ya kamata a lura da cewa 1JZ-GTE yana da wani simintin ƙarfe tubalan maimakon aluminum block, wanda ya kara da overall nauyi na mota, amma ya sa inji kasa mai saukin kamuwa da zafi fiye da kima.
Don haɓaka aminci, motar 1JZ-GTE ba a sanye take da ma'aunin zafi da zafi na hydraulic diyya, don haka ya kamata a daidaita tsaftar yanayin zafi a cikin tazarar kilomita 200.
Toyota Supra tana da tambarin Yamaha akan yanayin lokacin. Kamfanin babur ya taimaka wajen haɓaka injin. Hakanan zaka iya tunawa Toyota Celica 180, Yamaha ya ba da gudummawa sosai wajen ƙirƙirar injin bawul goma sha shida, injin mai sauri 2.0 don wannan motar kuma.
An shigar da motar 1JZ-GTE akan:
