I-Toyota 2JZ iyinjini ethandwa abashayeli. Funda kabanzi mayelana nenjini ye-2jz-GTE edumile nokuhluka kwayo

Kuyafaneleka futhi ukuthola ukuthi izinhlamvu zekhodi yenjini zibhekisela kuphi. Inombolo 2 ikhombisa isizukulwane, izinhlamvu JZ igama leqembu lenjini. Enguqulweni yezemidlalo ye-2-JZ-GTE, uhlamvu G lubonisa uhlobo lwezemidlalo lweyunithi - isikhathi se-valve esiphezulu esinama-shafts amabili. Esimeni sika-T, umenzi usho ukushaja kwe-turbo. U-E umele umjovo kaphethiloli we-elekthronikhi enguqulweni ye-2JZ enamandla kakhulu. Injini ichazwa njengeyunithi yehlelo. Uzothola ukuthi kungani kithi!

Ekuqaleni 90s - isikhathi lapho umlando kanye legend unit waqala

Ngasekuqaleni kwawo-90 waqala umlando izithuthuthu 2JZ. Injini ifakwe ezimotweni zakwaToyota neLexus. Isikhathi sokukhiqiza sivame ukubhekwa njengesiqongo sokukhiqiza izimoto zaseJapan. Izinjini ezisansimbi, eziqinile nezinkulu ezinamasilinda ayisithupha ezimotweni zabagibeli zenze ukuchaphazeka. Namuhla, i-motor enemininingwane enjalo ifakwe kuphela emalolini noma kuma-sedans amakhulu angemuva. Sethula ulwazi olubaluleke kakhulu mayelana namayunithi e-2JZ.

2JZ - injini evela kwaToyota. Ingxenye ebalulekile yomlando wezimoto

Ukuqala komlando weqembu lenjini kuhlotshaniswa nokudalwa kwe-Nissan Z. Abaqambi banquma ukuthi iyunithi izoba umncintiswano oqinile wenjini eyakhiwe ngabancintisana nabo. Kwenzeka kuma-70s. Ngakho, i-Celica Supra yadalwa nge-inline eyisithupha evela emndenini wakwa-M ngaphansi kwe-hood. Imoto yaqala emakethe ngo-1978, kodwa ayizange izuze impumelelo ebalulekile yokuthengisa. Kunalokho, kube yisinyathelo sokuqala ekukhiqizweni kochungechunge lwe-Supra olunamasilinda ayisithupha.

Eminyakeni emithathu ngemva kokuqala, kwenziwa ukuthuthukiswa okuphelele kwemoto. Ukubukeka kwemodeli ye-Celica kuklanywe kabusha. I-sporty version ye-Celica Supra inikwa amandla yinjini engu-six-cylinder M ene-turbo.

I-Supra yesizukulwane sesithathu evela kumkhiqizi waseJapane 

Ngo-1986, kwakhululwa isizukulwane sesithathu i-Supra, eyayingaseyona imodeli yochungechunge lwe-Celica. Imoto yayihlukaniswa nesiteji esikhulu, esithathwe kumodeli wesizukulwane sesibili se-Soarer. Imoto ibitholakala nezinjini ze-M ezinguqulweni ezahlukene. Phakathi kwezihamba phambili kukhona izinjini ezingu-7L turbocharged 7M-GE kanye ne-3,0M-GTE.

Inguqulo yokuqala yomndeni wakwa-JZ, i-1JZ, yethulwa ngo-1989. Ngakho, yathatha indawo yenguqulo endala ye-M. Ngo-1989, umsebenzi waqala futhi ekudaleni imodeli yemoto yesizukulwane sesine. Ngakho, ngemva kweminyaka emine, ngo-1993, "Supra A80" wangena ukukhiqizwa, okwaba yimpumelelo enkulu "Toyota" futhi phakade yathatha indawo yayo emlandweni wemboni yezimoto. 

I-Toyota Supra kanye ne-2JZ injini - izinguqulo ezahlukene zeyunithi yamandla

IToyota Supra esanda kwethulwa inezinjini ezimbili. Bekuyi-Supra enenjini engu-2 hp eshisekela ngokwemvelo engu-220JZ-GE. (164 kW) ku-285 Nm we-torque, kanjalo ne-2JZ-GTE i-twin-turbo version enamandla angu-276 hp. (206 kW) netorque engu-431 Nm. Ezimakethe zaseYurophu naseNyakatho Melika, amamodeli anama-turbocharger amancane anamasondo ensimbi ayevamile, kanye nama-injection amakhulu kaphethiloli, okwandisa amandla ku-321 hp. (etholakala e-US) kanye ne-326 hp. eYurophu. Njengoba ilukuluku, iyunithi waqala ukuvela hhayi imodeli Supra, kodwa ngo-1991 "Toyota Aristo". Nokho, le modeli yokukhiqiza yathengiswa kuphela eJapane. 

I-Iconic Japanese Engine Architecture

Isiphi isici esihlukanisayo isithuthuthu 2JZ? Injini yakhiwe phezu kwe-cast iron block block ene-reinforcement kanye nebhande eliqinile elifakwe phakathi kwebhulokhi ngokwayo nepani likawoyela. Abaklami baseJapane baphinde bahlomisa iyunithi ngabangaphakathi abaqinile. Izibonelo eziphawulekayo zihlanganisa i-crankshaft yensimbi efojiwe elinganisele ngokugcwele enamabheringi amakhulu omsebenzi osindayo kanye nama-crankpin awugqinsi angu-62mm no-52mm ngokulandelanayo. Izinti eziyindilinga ezifojiwe nazo zibonise ukusebenza okuzinzile. Kungenxa yalokhu ukuthi ukumelana nokugqoka okuphezulu kuqinisekiswa, kanye namandla amakhulu amakhulu. Phakathi kwezinye izinto, ngenxa yalezi zixazululo, iyunithi ibhekwa njengenjini edumile.

Injini engu-2JZ-GTE ikhiqize amandla amangalisayo. Yiziphi izici ezitholwe ngokushuna imoto?

I-Toyota iphinde yasebenzisa i-high-pressure cast hypereutectic pistons kule njini, ehlala isikhathi eside kakhulu. Lokhu bekusho ukuthi ingatholwa ifinyelela ku-800 hp ngokushuna imoto. kusuka enjinini enalezi zingxenye. 

Onjiniyela baphinde bakhetha ama-valve amane isilinda ku-aluminium ephindwe kabili ye-cam cylinder head, enani lama-valve angama-24. Okuhlukile kwe-2JZ-GTE iyinjini eyi-turbo ephindwe kabili. Injini ye-turbine yegesi ifakwe ama-turbocharger amabili alandelanayo, lapho enye yawo ivula ngesivinini esiphansi senjini, kanti enye iphezulu - ku-4000 rpm. 

Lezi zinhlobo ziphinde zasebenzisa ama-turbocharger afanayo aletha amandla abushelelezi nalayini kanye ne-torque engu-407 Nm ku-1800 rpm. Lena kube yimiphumela emihle kakhulu, ikakhulukazi uma kuziwa kudivayisi eyakhiwe ekuqaleni kwawo-90s.

Kuyini ukuthandwa isithuthuthu 2JZ? Injini ibonakala, isibonelo, kuma-cinema womhlaba kanye nemidlalo yekhompyutha. I-Supra eneyunithi yesakhiwo sodumo ivele ku-movie ethi "Fast and the Furious", kanye nasemdlalweni Isidingo Sokusheshisa: Ngaphansi Komhlaba, futhi yangena phakade ezingqondweni zabashayeli njengemodeli yehlelo elinamandla amangalisayo.
