Cav 7A-FE
Txoj kev loj hlob ntawm A-series xyaw ntawm Toyota pib rov qab rau hauv 70s ntawm lub xyoo pua xeem. Qhov no yog ib qho ntawm cov kauj ruam ntawm kev txo cov roj noj thiab nce kev ua tau zoo, yog li txhua chav nyob ntawm cov koob tau zoo heev ntawm qhov ntim thiab lub zog.
Cov neeg Nyij Pooj tau ua tiav cov txiaj ntsig zoo hauv xyoo 1993 los ntawm kev tso tawm lwm qhov kev hloov kho ntawm A series - lub cav 7A-FE. Ntawm nws cov tub ntxhais, chav tsev no yog ib qho kev hloov kho me ntsis ntawm cov qauv yav dhau los, tab sis nws raug suav hais tias yog ib qho ntawm kev ua tiav zoo tshaj plaws hauv kev sib xyaw ua ke hauv cov koob.
Cov ntaub ntawv qhia
Qhov ntim ntawm lub tog raj kheej tau nce mus rau 1.8 litres. Lub cev muaj zog pib tsim 115 horsepower, uas yog ib tug heev daim duab rau xws li ib tug ntim. Cov yam ntxwv ntawm lub cav 7A-FE yog qhov nthuav nyob rau hauv qhov kev pom zoo torque yog muaj los ntawm qis revs. Rau kev tsav tsheb hauv nroog, qhov no yog khoom plig tiag tiag. Thiab tseem nws tso cai rau koj txuag roj los ntawm tsis scrolling lub cav nyob rau hauv qis zog mus rau high speeds. Feem ntau, cov yam ntxwv yog raws li nram no:
| Xyoo ntawm kev tsim khoom | 1990-2002 |
| Cov ntim ua haujlwm | 1762 kub |
| Qhov ntau zog | 120 lub zog |
| Torque | 157 Nm ntawm 4400 rpm |
| Lub tog raj kheej taub | 81.0 hli |
| Piston mob stroke | 85.5 hli |
| Lub tog raj kheej thaiv | cam khwb cia hlau |
| Lub taub hau kheej kheej | aluminium |
| Gas qhov system | DOHC |
| Roj hom | roj av |
| Yam ua ntej | 3T |
| Kev vam meej | 1ZZ |
Qhov tseeb nthuav dav yog qhov muaj ob hom 7A-FE cav. Ntxiv nrog rau cov qauv siv hluav taws xob, cov neeg Nyij Pooj tau tsim thiab nquag ua lag luam kev lag luam ntau dua 7A-FE Lean Burn. Los ntawm leaning qhov sib tov nyob rau hauv lub intake manifold, qhov siab tshaj plaws kev khwv nyiaj txiag yog tiav. Yuav kom ua raws li lub tswv yim, nws yog ib qho tsim nyog yuav tau siv cov khoom siv hluav taws xob tshwj xeeb, uas tau txiav txim siab thaum twg nws tsim nyog depleting qhov sib tov, thiab thaum twg nws yuav tsum tau muab cov roj av ntxiv rau hauv lub chamber. Raws li kev txheeb xyuas ntawm cov tswv tsheb nrog xws li lub cav, chav tsev yog tus cwj pwm los ntawm kev siv roj tsawg.
Cov yam ntxwv ntawm kev ua haujlwm 7A-FE
Ib qho ntawm qhov zoo ntawm kev tsim lub cev muaj zog yog qhov kev puas tsuaj ntawm kev sib dhos xws li 7A-FE lub sijhawm siv lub sijhawm tshem tawm cov kev sib tsoo ntawm li qub thiab piston, i.e. Hauv cov ntsiab lus yooj yim, lub cav tsis khoov lub valve. Nyob rau hauv nws cov tub ntxhais, lub engine yog heev hardy.
Qee tus tswv ntawm qib siab 7A-FE chav nyob nrog lub tshuab hluav taws xob tsis zoo hais tias cov khoom siv hluav taws xob feem ntau coj tus cwj pwm tsis zoo. Tsis yog ib txwm, thaum koj nias lub pedal accelerator, qhov sib tov sib xyaw yog muab tua, thiab lub tsheb coj tus cwj pwm tsis zoo, lossis pib twitch. Tag nrho cov teeb meem uas tshwm sim nrog lub hwj chim chav tsev no yog ib tug kheej kheej thiab tsis loj heev.
Lub cav 7A-FE nyob qhov twg?
Tsis tu ncua 7A-FEs tau npaj rau C-chav tsheb. Tom qab kev sim ua tiav ntawm lub cav thiab cov lus pom zoo los ntawm cov neeg tsav tsheb, kev txhawj xeeb tau pib nruab lub tsev ntawm cov tsheb hauv qab no:
| Tus qauv | Lub cev | Ntawm lub xyoo | lub teb chaws |
|---|---|---|---|
| Avensis | AT211 | 1997-2000 | Teb chaws Europe |
| Caldina | AT191 | 1996-1997 | Nyiv |
