Injini 7A-FE
Ukuthuthukiswa kwezinjini ze-A-series kwaToyota kwaqala emuva kuma-70s ekhulwini elidlule. Lesi bekungesinye sezinyathelo zokunciphisa ukusetshenziswa kukaphethiloli nokwandisa ukusebenza kahle, ngakho-ke wonke amayunithi ochungechunge abenesizotha ngokwevolumu namandla.
AmaJapane athola imiphumela emihle ngo-1993 ngokukhulula okunye ukuguqulwa kochungechunge lwe-A - injini ye-7A-FE. Emgogodleni wayo, le yunithi yayiyisibonelo esishintshiwe kancane sochungechunge lwangaphambilini, kodwa ibhekwa ngokufanelekile njengenye yezinjini zomlilo zangaphakathi eziphumelela kakhulu ochungechungeni.
Idatha yezobuchwepheshe
Umthamo wamasilinda unyuswe waba ngamalitha ayi-1.8. Injini yaqala ukukhiqiza amandla angu-115, okuyinani eliphakeme kakhulu levolumu enjalo. Izici zenjini engu-7A-FE ziyathakazelisa ngoba itorque efanelekile itholakala kumarevs aphansi. Ukushayela edolobheni, lesi isipho sangempela. Futhi ikuvumela ukuthi wonge uphethiloli ngokungapheqi injini ngamagiya aphansi uye esivinini. Ngokuvamile, izici zimi kanje:
| Unyaka wokukhiqiza | 1990-2002 |
| Ukusebenza kwevolumu | 1762 cubic amasentimitha |
| Amandla aphezulu | 120 amandla wehhashi |
| I-Torque | 157 Nm ku-4400 rpm |
| Ububanzi besilinda | 81.0 mm |
| Ukushaya kwesibhamu | 85.5 mm |
| Isilinda block | Insimbi |
| Ikhanda lesilinda | i-aluminium |
| Uhlelo lokusabalalisa igesi | I-DOHC |
| Uhlobo lwamafutha | uphethiloli |
| Kwandulelwa | 3T |
| Umlandeli | 1ZZ |
Iqiniso elithakazelisa kakhulu ukuthi kukhona izinhlobo ezimbili zenjini engu-7A-FE. Ngokungeziwe kuma-powertrains ajwayelekile, amaJapan athuthukise futhi adayisela i-7A-FE Lean Burn eyonga kakhulu. Ngokuncika ingxube ekusetshenzisweni okuningana, umnotho omkhulu ufinyelelwa. Ukuze kusetshenziswe lo mbono, kwakudingeka kusetshenziswe i-electronics ekhethekile, eyanquma ukuthi kufaneleka nini ukuqeda ingxube, futhi lapho kudingekile ukufaka uphethiloli owengeziwe ekamelweni. Ngokusho kokubuyekezwa kwabanikazi bezimoto abanenjini enjalo, iyunithi ibonakala ngokunciphisa ukusetshenziswa kukaphethiloli.
Izici zokusebenza 7A-FE
Enye yezinzuzo zokuklama kwezimoto ukuthi ukubhujiswa komhlangano onjalo njengebhande lesikhathi le-7A-FE kuqeda ukungqubuzana kwama-valve ne-piston, i.e. ngamazwi alula, injini ayigobi i-valve. Emongweni wayo, injini iqinile kakhulu.
Abanye abanikazi bamayunithi athuthukile e-7A-FE anesistimu yokushiswa kancane bathi izinto zikagesi zivame ukuziphatha ngendlela engalindelekile. Hhayi njalo, lapho ucindezela i-accelerator pedal, isistimu yengxube ethambile iyacishwa, futhi imoto iziphatha ngokuzola kakhulu, noma iqale ukunyakaza. Ezinye izinkinga eziphakamayo ngale yunithi yamandla ezemvelo yangasese futhi azinkulu.
Ifakwe kuphi injini ye-7A-FE?
Ama-7A-FE ajwayelekile ayehloselwe izimoto ze-C-class. Ngemva kokuhlolwa okuphumelelayo kwenjini kanye nempendulo enhle evela kubashayeli, ukukhathazeka kwaqala ukufaka iyunithi kulezi zimoto ezilandelayo:
| Imodeli | Umzimba | Yonyaka | izwe |
|---|---|---|---|
| I-Avensis | AT211 | 1997-2000 | IYurophu |
| Caldina | AT191 | 1996-1997 | Japan |
| Caldina | AT211 | 1997-2001 | Japan |
| UCarina | AT191 | 1994-1996 | Japan |
| UCarina | AT211 | 1996-2001 | Japan |
| UCarina E | AT191 | 1994-1997 | IYurophu |
| ICelica | AT200 | 1993-1999 | Ngaphandle kwaseJapan |
| I-Corolla/Conquest | AE92 | Septhemba 1993 - 1998 | ENingizimu Afrika |
| I-Corolla | AE93 | 1990-1992 | E-Australia kuphela |
| I-Corolla | I-AE102/103 | 1992-1998 | Ngaphandle kwaseJapan |
| I-Corolla/Prizm | AE102 | 1993-1997 | ENyakatho Melika |
| I-Corolla | AE111 | 1997-2000 | ENingizimu Afrika |
| I-Corolla | I-AE112/115 | 1997-2002 | Ngaphandle kwaseJapan |
| I-Corolla Space | AE115 | 1997-2001 | Japan |
| Corona | AT191 | 1994-1997 | Ngaphandle kwaseJapan |
| Umklomelo Womqhele | AT211 | 1996-2001 | Japan |
| Umgijimi Carib | AE115 | 1995-2001 | Japan |
Izinjini ze-A-series zibe umfutho omuhle ekuthuthukisweni kokukhathazeka kwaToyota. Lokhu kuthuthukiswa kwathengwa ngenkuthalo ngabanye abakhiqizi, futhi namuhla ukuthuthukiswa kwezizukulwane zakamuva zamayunithi wamandla anenkomba A kusetshenziswa imboni yezimoto yamazwe asathuthuka.
