Injini 2JZ-GTE
Okuqukethwe
Injini engu-2JZ-GTE ingenye yezinhlobo ezinamandla kakhulu ze-powertrain ochungechungeni lwe-2JZ. Ihlanganisa ama-turbo amabili ane-intercooler, inama-camshaft amabili anebhande elisuka ku-crankshaft futhi inamasilinda ayisithupha aqondile. Ikhanda le-cylinder lenziwe nge-aluminium futhi lenziwe ngabakwaToyota Motor Corporation, futhi injini ngokwayo iyinsimbi ekhonjiwe. Lokhu motor senziwa kuphela eJapane kusukela ngo-1991 kuya ku-2002.
I-2JZ-GTE ibiqhudelana nenjini yakwaNissan i-RB26DETT, ephumelele emqhudelwaneni we-NTuringCar kanye ne-FIA.
Imishini eyengeziwe esebenza kulolu hlobo lwamamotho
I-2JZ-GTE motor yayinezinhlobo ezimbili zama-gearbox:
- 6-speed manual transmission Toyota V160 kanye V161;
- 4-speed automatic transmission Toyota A341E.
Le moto yaqale yafakwa kuhlobo lweToyota Aristo V, kodwa yabe isifakwa kwiToyota Supra RZ.
Ukuguqulwa okusha kwenjini kanye nezinguquko ezinkulu
Isisekelo se-2JZ-GTE yinjini engu-2JZ-GE, eyasungulwa ngabakwaToyota phambilini. Ngokungafani ne-prototype, i-turbocharger ene-intercooler eseceleni yafakwa ku-2JZ-GTE. Futhi, kuma-pistons enjini ebuyekeziwe, ama-grooves kawoyela amaningi enzelwe ukupholisa okungcono kwama-piston ngokwawo, futhi ama-recesses nawo enziwa ukunciphisa lokho okubizwa ngokuthi isilinganiso sokucindezela ngokomzimba. Izinduku zokuxhuma, i-crankshaft namasilinda afakwe ngokufanayo.
Ezimotweni ze-Aristo Altezza ne-Mark II, kwabe sekufakwe ezinye izinduku zokuxhuma uma ziqhathaniswa neToyota Aristo V neSupra RZ. Futhi, injini ngo-1997 yaphothulwa uhlelo VVT-i.. Lolu hlelo lwashintsha izigaba zokusatshalaliswa kwegesi futhi lwenza kwaba nokwenzeka ukwandisa kakhulu i-torque namandla enjini yokuguqula engu-2JZ-GTE.
Ngokuthuthuka kokuqala, i-torque yayilingana no-435 N * m, nokho, ngemva komshini omusha we-2JZ-GTE vvti ngo-1997, i-torque yanda futhi ilingana no-451 N * m. Amandla enjini ye-base 2JZ-GE anyuswe ngenxa yokufakwa kwe-turbocharger ephindwe kabili eyakhiwe yi-Toyota kanye ne-Hitachi. Kusuka ku-227 hp 2JZ-GTE twin turbo amandla anyukele ku-276 hp kuma-revolutions alingana nama-5600 ngomzuzu. Futhi ngo-1997, amandla eyunithi yamandla eToyota 2JZ-GTE asekhulile afinyelela ku-321 hp. ezimakethe zaseYurophu kanye naseNyakatho Melika.
Izinguqulo zenjini ezithekelisiwe
Inguqulo enamandla kakhulu yakhiqizwa iToyota ukuze ithunyelwe ngaphandle. Injini engu-2JZ-GTE ithole amandla ekufakweni kwama-turbocharger ensimbi engagqwali, ngokungafani nokusetshenziswa kwezitsha zobumba ezinjinini zemakethe yaseJapan. Ngaphezu kwalokho, ama-injection nama-camshafts athuthukisiwe, akhiqiza ingxube kaphethiloli eyengeziwe ngomzuzu. Ukunemba, ngu-550 ml/min wokuthekelisa kanye no-440 ml/min emakethe yaseJapane. Futhi, ukuthunyelwa kwamanye amazwe, amaturbine e-CT12B afakwe ngokuphindwe kabili, futhi emakethe yasekhaya, i-CT20, futhi ngenani lama-turbines amabili. Ama-Turbines CT20, nawo, ahlukaniswe ngezigaba, ezikhonjiswe ngezinhlamvu ezengeziwe: A, B, R. Ngezinketho ezimbili zenjini, ukushintshashintsha kwesistimu yokukhipha umoya kwakungenzeka ngenxa yengxenye yemishini yama-turbines.
Imininingwane yenjini
Naphezu kwencazelo eningiliziwe engenhla yokwakhiwa kwenjini yemodeli ye-2JZ-GTE, kunezici ezimbalwa ezibalulekile okufanele uzinake. Ukuze kube lula, izici ze-2JZ-GTE zinikezwa ngendlela yetafula.
| Inani lamasilinda | 6 |
| Ukuhlelwa kwesilinda | emugqeni |
| Amaphayiphu | VVT-i, DOHC 24V |
| Umshini wenjini | I-3 l. |
| Amandla, h. | 321hp / 451 N*m |
| Izinhlobo ze-turbine | I-CT20/CT12B |
| Uhlelo lwe-Ignition | Umsabalalisi / DIS-3 |
| Uhlelo lokujova | I-MPFI |
Uhlu lwezimoto okwafakwa kuzo injini
Kuyaqapheleka ukuthi le modeli yenjini ifakazele ukuthi iyunithi yamandla ethembekile futhi engenasizotha ekunakekeleni. Ngokusho kolwazi, lokhu kuguqulwa kwemoto kufakwe kumamodeli emoto afana nalokhu:
- Toyota Supra RZ/Turbo (JZA80);
- IToyota Aristo (JZS147);
- I-Toyota Aristo V300 (JZS161).
Ukubuyekezwa kwabanikazi bezimoto, abanezinjini ze-2JZ-GTE
Kuyaphawuleka ukuthi, ukwahlulela ukubuyekezwa, kwakungekho ukushiyeka okusobala injini yalokhu kuguqulwa. Ngokulungiswa okuvamile nokunekhono, yabonakala iyinjini enokwethenjelwa kakhulu, lapho imingcele yayo inokusetshenziswa okuphansi kukaphethiloli. Amasilinda aphoqeleka ukuthi asebenzise amapulaki e-platinum, njengoba amakhandlela kunzima kakhulu ukuwathola. Ukukhipha okuncane kumayunithi afakwe eMelika ane-hydraulic tensioner.
Kodwa-ke, ngokuvamile, kwakuyile modeli ethile yeyunithi yamandla okwahlala isikhathi eside ihola ngokwezinga nezinga lokusebenza.
