Injini 1JZ-GTE
Injini engu-1JZ-GTE ayinayo insumansumane, ngenxa yokuthi yilesi sithupha esine-turbocharged inline six esinikeza i-2th Supra, Mark 1 Tourer V namanye amaToyota asheshayo amandla. Emgogodleni wayo, i-1JZ-GTE inguqulo ene-turbocharged ye-XNUMXJZ-GE efiselekayo ngokwemvelo.
Isizukulwane sokuqala i-1JZ-GTE sasifakwe izinjini zomoya ezimbili ezibekwe ngokuhambisana eduze kwendawo yokuphehla ugesi. Amaturbine amabili amancane uma kuqhathaniswa - i-CT12A, uma kuqhathaniswa ne-1JZ evamile, amandla akhuphuka ngo-80 hp. Ukwenyuka kwamandla amahhashi angu-80 enjini efakwe i-turbo ephindwe kabili akubalulekile kakhulu, ikakhulukazi uma ucabangela ukucindezela kwe-0.7 bar. Konke mayelana nezici zomthetho Japanese, okuyinto ngaleyo minyaka benqabela ukukhiqizwa izimoto, ogama amandla angaphezu kuka-280 amahhashi. Amandla amakhulu angu-280 hp atholwa ngokushintshashintsha kwe-crankshaft okungu-6200 ngomzuzu, amandla amakhulu okudonsa enjini engu-1JZ-GTE ngu-363 N.m ekuguquleni okungu-4.
Kubuyekezwe 1JZ-GTE, 1996
Ngo-1996, amaJapane avuselela injini, futhi kwavela i-1JZ-GTE vvti. Ngaphezu kokuthi injini ye-turbo ithole uhlelo olushintsha isikhathi se-valve, i-twin turbo yinto yesikhathi esidlule. AmaJapane, esikhundleni sama-turbine amabili ahambisanayo, aqala ukufaka eyodwa, kodwa enkulu - i-CT15B.
Ngaphezu kwezinguquko ezithinta uhlelo lokushaja okuphezulu, injini ebuyekeziwe ithole isilinganiso esiphezulu sokucindezela. Uma ezinjinini ezinama-turbines amabili bekungu-8.5:1, bese kuthi i-single-turbine 1JZ-GTE ine-compression ratio inyuke yaba ngu-9.0:1. Ukwenyuka kwesilinganiso sokucindezela kwenze kwaba nokwenzeka ukukhulisa i-torque ku-379 N.M futhi kwenza isikhungo samandla kagesi sibe ngu-10% ukonga kakhulu. Ukucindezelwa okuphezulu impela, njengenjini ene-turbocharged, ibeka izimfuno eziphezulu kwikhwalithi kaphethiloli. Kunconywa ukunika amandla injini engu-1JZ-GTE ngophethiloli ngesilinganiso se-octane okungenani esingu-95, futhi uma kubhekwa izinga elingagculisi likaphethiloli wethu, ukugwema ingozi yokuqhunyiswa, kungcono ukugcwalisa uphethiloli we-98-octane.
Ngo-1 i-1996JZ-GTE, iziteshi zokupholisa zashintshwa, okwanciphisa amathuba okushisa kwenjini. I-geometry ye-injini ayizange ishintshe ngesikhathi sesimanje: kokubili ngaphambi nangemva kokulungiswa kabusha, ububanzi be-cylinder buyi-86 mm kanye ne-piston stroke 71.5 mm. Ijiyomethri yenjini enjalo, lapho ububanzi besilinda budlula i-piston stroke, inquma ukuphakama kwe-torque ngaphezu kwamandla amakhulu.
Naphezu kokuthi izici zesimanje ze-1JZ-GTE "ephepheni" sezithuthukisiwe, injini ye-twin-turbo "phezulu" iphotha "injabulo eyengeziwe", ngenxa yalesi sizathu, abanye abalandeli be-tuning bafuna i-pre. -ilungisa kabusha i-1JZ-GTE twin turbo.
Isilinganiso sikaphethiloli esisetshenziswa yi-1JZ-GTE silinganiselwa ku-12 litres, kodwa ezimeni zangempela ukusetshenziswa kunyuka kalula kube ku-25 litres.

Ukungasebenzi kahle nokugcinwa kwe-1JZ-GTE
Abanikazi be-Supr bayaqaphela ukuthi ngenxa yokungabi namandla, ama-pistons anganamathela, okuholela ekulahlekelweni kokucindezela kumasilinda. Ngenxa "ezansi" ezinamandla kakhulu, i-decarbonization ikuvumela ukuthi ubuyisele ukucindezelwa kumanani we-atmospheres engu-12. Amayunithi afile we-1JZ-GTE, naphezu kokusetshenziswa okusebenzayo ngabanikazi abaningi, awavamile, kodwa uma kunesidingo, ungakwazi uku-oda injini yenkontileka. Ngokushintshwa kwamafutha okufika ngesikhathi, okufanele kwenziwe njalo ngebanga lika-7 000 km, ngoba ama-turbines nawo ahlanzwa ngamafutha enjini, i-1GZ-GTE izohlala amakhilomitha angama-300 ngaphambi kokushintsha izindandatho. Ngenxa yokushisa ngokweqile, izindandatho zingadinga ukushintshwa ngaphambili kakhulu kunezinkulungwane ezingu-300. Nge-mileage ye-300 km, kuhle futhi ukufaka esikhundleni se-crankshaft oil seal, engase iqale ukuvuza ku-mileage enjalo. I-idling engazinzile, kanye nokwehluleka lapho ucindezela i-pedal yegesi, kungabangelwa inzwa yokugeleza komoya enephutha.
Kuyaphawuleka ukuthi i-1JZ-GTE ine-cast iron block kune-aluminium, ekhulisa isisindo semoto, kodwa yenza injini ingabi lula ekushiseni.
Ukuze kwandiswe ukuthembeka, injini ye-1JZ-GTE ayizange ifakwe izinxephezelo ze-hydraulic thermal gap, ngakho-ke izikhala ezishisayo kufanele zilungiswe ngezikhathi ezingu-200 km.
Kunophawu lwe-Yamaha lapho kwakhiwa khona isikhathi seToyota Supra. Inkampani yezithuthuthu yasiza ekuthuthukiseni injini. Ungakhumbula futhi iToyota Celica 180; Yamaha yabamba iqhaza elikhulu ekwakhiweni kwenjini enama-valve ayishumi nesithupha, enejubane eliphezulu engu-2.0 yale moto nayo.
Injini engu-1JZ-GTE ifakwe ku:
- Chaser;
- Crest;
- uMarku II, uMark II Blit;
- Ngaphezulu kwe-MK III;
- I-Verosa;
- Soarer;
- Umqhele.
Injini engu-1JZ-GTE yaziwa ngohlu olubanzi lwamathuba okushintshwa kanye nokwanda kwamandla. Naphezu kwefekthri engu-280 hp, yona ngokwayo engencane, ungakwazi ukwandisa amandla ku-600 - 700 hp ngokumane ushintshe okunamathiselwe.
