1 VZ-FE injini
Madalaivala onse ali okonzeka kutsimikizira kuti injini zopangidwa ku Japan ndi mphamvu zodalirika zomwe, ndi ntchito yabwino, zimakhala ndi nthawi yosinthira mpaka 1 miliyoni km. Zomera zamagetsi zopangidwa ndi Toyota ndizodziwika kwambiri pa izi. Imodzi mwa injini zimenezi ndi injini "toyota 1VZ-FE", amene ntchito kutsiriza kusinthidwa CAMRY (kutengera msika American magalimoto - VISTA).
Mbiri ya injini
Ntchito mpaka 1988 mu mtundu wa magalimoto a kampani "Toyota MZ" mphamvu wagawo sanali mokwanira zofunika makokedwe pafupifupi, amene anayambitsa mavuto ena pa ntchito ya zida. Panthawi imeneyi, "Nissan" anayambitsa latsopano VG injini, amene anakumana ndi zinthu zofunika ntchito. Kuonjezera malonda galimoto mu msika wa magalimoto padziko lonse ndi kulimbana ndi makampani mpikisano, Toyota okonza apanga latsopano 2-lita mafuta injini ndi camshafts awiri mu yamphamvu mutu (DOHC), amene analandira chidule cha 1VZ-FE.
Mafotokozedwe a injini
Timapereka mikhalidwe yayikulu ya 1VZ-FE ikugwira ntchito.
| Ntchito yomanga | injini yokhala ndi mafuta amtundu wa jekeseni wogawidwa, womwe uli ndi masilindala 6 okhala ndi mavavu 24 opangidwa mu mawonekedwe a V. |
| Chiwerengero | 2 l. (1992 cc) |
| Kugwiritsa ntchito mphamvu | 136 HP pofika 6000 rpm |
| Mphungu | 173 Nm pa 4600 rpm |
| Chiyerekezo cha kuponderezana | 9.6 atm |
| Piston gulu lalikulu | 78 мм |
| Stroke mu block | 69.5 мм |
| Kugwiritsa ntchito mafuta pafupipafupi | 9,8l ndi. pa 100km |
| Analimbikitsa mafuta | AI-92 mafuta |
| Makina oyatsira ogwiritsidwa ntchito | ndi breaker - distributor |
| kusintha moyo | Makilomita a 400000 |
Mu 1991, kampaniyo inasiya kupanga injini izi, zomwe zisanachitike zidachepetsa kwambiri kuchuluka kwa kupanga, popeza zofooka zingapo zogwirira ntchito zidadziwika. Chigawo chatsopano cha mphamvu chinapangidwa pansi pa chidule cha Toyota GR, chomwe chinaganizira zofooka za chitsanzo chake - 1VZ-FE injini yoyaka mkati, yomwe inayikidwa pa magalimoto otsatirawa:
- Camry Prominent mu VZV20 ndi VZV3x matupi (1988-1991);
- Vista (1988-1991 g.).
Mapangidwe a injini ya 1VZ-FE
Ubwino waukulu wa mphamvu yamagetsi iyi inali yokwera kwambiri ya torque pa liwiro lotsika, zomwe zidapangitsa kuti zigwiritsidwe ntchito pamitundu yamagalimoto monga ma crossovers, magalimoto ang'onoang'ono ndi ma minibasi. Monga injini zonse za Toyota zomwe zinapangidwa panthawiyo, zinali ndi midadada yachitsulo. Kuphatikiza apo, unit yokhala ndi ma silinda owoneka ngati V imakhala yokwera kuposa injini yokhala ndi makonzedwe apakati a gulu la pisitoni. Izi zimakuthandizani kuti muchepetse mphamvu yonyamula katundu pa crankshaft, zomwe zimabweretsa kuwonjezeka kwa mphamvu zamagetsi zotere. Panthawi imodzimodziyo, mayunitsi oterewa ndi ovuta kwambiri, ali ndi mafuta ambiri, injini, ngakhale mumkhalidwe wangwiro, nthawi "imatenga" mafuta enaake. Mfundo ina yofooka ndikuwonjezereka kwa manyuzipepala akuluakulu a crankshaft. Ndipo mtengo wa zida zosinthira ndi wokwera kwambiri kuti ukwaniritse kuyendetsa galimotoyo mwadongosolo. Eni magalimoto okhala ndi mphamvu zotere nthawi zambiri amadandaula za hydraulic fan drive, yomwe ndi yosadalirika komanso yolakwika, yomwe nthawi zambiri imayambitsa kutenthedwa kwa injini ndi zolakwika zina. Choncho, kukonza 1VZ-FE ndi zosangalatsa m'malo mtengo.
Pomaliza
Zopangidwa ndi okonza Japanese a Toyota, galimoto lonse sanali kulungamitsa ziyembekezo za oyambitsa ake. Pantchitoyi, idakhala gawo losadalirika komanso lopanda chilema, kulola kuphwanya ulamuliro wamafuta ogwiritsira ntchito makina oziziritsa.
