Injini ya D4D ku Toyota - zomwe muyenera kudziwa za unit?

Galimotoyo idapangidwa mogwirizana pakati pa Toyota ndi Denso Corporation. Amagwiritsa ntchito njira zomwe zimadziwika ndi injini zamakono za dizilo. Izi zikuphatikiza, mwachitsanzo, kugwiritsa ntchito mamapu akuyatsa poyang'anira injini pogwiritsa ntchito TCCS.

Kodi injini ya D4D idapangidwa liti ndipo ndi magalimoto ati omwe amagwiritsidwa ntchito?

Ntchito pa block ya D4D idayamba kale mu 1995. Kugawidwa kwa magalimoto oyamba ndi injini iyi kunayamba mu 1997. Msika waukulu unali ku Ulaya, chifukwa chipangizocho sichinali chodziwika kwambiri ku Asia kapena ku United States, ngakhale kuti Toyota amagulitsa magalimoto ambiri kumeneko.

Injini ya D4D imagwiritsidwa ntchito mu injini za dizilo za Toyota, koma pali zosiyana ndi lamuloli - izi ndizomwe zimachitika pamagulu omwe amagwiritsidwa ntchito ndi D-CAT. Ichi ndi chitukuko cha dongosolo D4D ndi kuthamanga jekeseni ndi apamwamba kuposa dongosolo choyambirira - 2000 bar, osati osiyanasiyana 1350 mpaka 1600 bar. 

Mitundu yodziwika bwino yamagulu kuchokera ku Toyota

Chimodzi mwazinthu zodziwika bwino za injini ya Toyota chinali 1CD-FTV. Okonzeka ndi Common Rail system. Inali ndi voliyumu yogwira ntchito ya malita 2 ndi mphamvu ya 116 hp. Kuphatikiza apo, mapangidwewo amaphatikiza masilinda anayi am'mizere, makoma a silinda olimbikitsidwa ndi geometry turbocharger yosinthika. Gawo la 1CD-FTV linapangidwa mpaka 2007. Mitundu yamagalimoto yomwe idayikidwapo:

• Toyota Avensis?
• Corolla;
• M'mbuyomu;

1ND-TV

Chofunikiranso kutchulidwa ndi chipika cha 1ND-TV. Inali inline ya four-cylinder turbocharged dizilo. Inali ndi kusuntha kwa malita 1,4 ndipo, monga mayunitsi ena a D-4D, idagwiritsa ntchito jekeseni wamafuta a Common Rail. Pankhani ya 1ND-TV, mphamvu yayikulu ndi 68,88 ndi 90 hp, ndipo gawolo limagwirizana ndi miyezo ya EURO VI yotulutsa. Mitundu yamagalimoto yomwe idayikidwa ndi injini iyi ndi:

• Auris;
• Corolla;
• Yaris;
• S-vesi;
• Etios.

1KD-FTV ndi 2KDFTV

Pankhani ya 1KD-FTV, tikukamba za injini ya dizilo yokhala ndi ma silinda anayi okhala ndi ma camshaft awiri ndi turbine ya 3-lita yokhala ndi mphamvu ya 172 hp. Zayikidwa pamagalimoto:

• Land Cruiser Prado;
• Hilux Surf;
• Fortuner;
• Hyasi;
• Hilux.

Kumbali ina, m'badwo wachiwiri udafika pamsika mu 2001. Inali ndi kusuntha kochepa komanso mphamvu yaikulu kuposa yomwe idakonzedweratu: 2,5 malita ndi 142 hp. Analipo m'magalimoto monga:

• Fortuner;
• Hilux;
• Hyasi;
• Innova.

AD-FTV

Chigawo cha mndandandawu chinayambitsidwa mu 2005. Anali ndi turbocharger, komanso kusamuka kwa malita 2.0 ndi mphamvu ya 127 hp. M'badwo wachiwiri, 2AD-FTV, unali ndi D-4D njanji wamba, komanso variable geometry turbocharger ndi kusamuka kwa malita 2,2. Mphamvu zazikuluzikulu zimachokera ku 136 mpaka 149 hp.

Mbadwo wachitatu wa unit unapangidwanso. Inalandira dzina lakuti 2AD-FHV ndipo inali ndi majekeseni othamanga kwambiri a piezo. Okonzawo adagwiritsanso ntchito dongosolo la D-CAT, lomwe limachepetsa kutulutsa zinthu zovulaza. Compress ratio inali 15,7: 1. Voliyumu yogwira ntchito inali malita 2,2, ndipo gawolo limapereka mphamvu kuchokera ku 174 mpaka 178 hp. Magawo omwe adalembedwa adagwiritsidwa ntchito ndi eni magalimoto monga:

• RAV4;
• Avensis;
• Corolla Verso;
• Auris.

1GD-FTV

Mu 2015, m'badwo woyamba wa 1GD-FTV unit idayambitsidwa. Inali 2,8-lita inline unit yokhala ndi 175 hp DOHC injini. Inali ndi masilinda 4 ndi geometry turbocharger yosinthika. Kwa m'badwo wachiwiri, 2GD-FTV inali ndi kusuntha kwa malita 2,4 ndi mphamvu ya 147 hp. Mitundu iwiriyi inali ndi chiŵerengero chofanana cha 15: 6. Mayunitsi anaikidwa pa zitsanzo monga:

• Hilux;
• Land Cruiser Prado;
• Fortuner;
• Innova.

1 VD-FTV

Gawo latsopano m'mbiri ya injini za Toyota linali kukhazikitsidwa kwa unit 1 VD-FTV. Inali injini ya dizilo yooneka ngati V-8 ya silinda yoyamba yokhala ndi malita 4,5. Ili ndi dongosolo la D4D, komanso ma turbocharger a geometry amodzi kapena awiri. Mphamvu pazipita wa unit turbocharged anali 202 HP, ndi turbo amapasa anali 268 HP.

Kodi zovuta za dizilo zofala kwambiri ndi ziti?

Chimodzi mwazowonongeka kwambiri ndi kulephera kwa majekeseni. Injini ya Toyota D4D siigwira ntchito bwino, komanso imadya mafuta ambiri, kapena phokoso kwambiri.

Pali zolephera mu midadada 3.0 D4D. Zimakhudzana ndi kutenthedwa kwa mphete zosindikizira, zomwe zimapangidwa ndi mkuwa ndipo zimayikidwa pamagetsi opangira mafuta. Chizindikiro cha kusokonekera ndi utsi woyera wochokera mu injini. Komabe, kumbukirani kuti ndi kukonza nthawi zonse unit ndi m'malo zigawo zikuluzikulu, D4D injini ayenera kukubwezerani ntchito yosalala ndi khola.
