D4D engine mai Toyota - he aha kāu e ʻike ai e pili ana i ka ʻāpana?

Ua hoʻomohala ʻia ka kaʻa ma ka launa pū ʻana ma waena o Toyota a me Denso Corporation. Hoʻohana ʻo ia i nā hopena i ʻike ʻia mai nā mīkini diesel hou. ʻO kēia mau mea, no ka laʻana, ka hana o nā palapala ʻāina i ka wā e hoʻokele ai i ka ʻenekini me ka hoʻohana ʻana i TCCS.

I ka manawa hea i hana ʻia ai ka mīkini D4D a ma hea nā kaʻa e hoʻohana ʻia ai?

Ua hoʻomaka ka hana ma ka poloka D4D i ka makahiki 1995. Hoʻomaka ka māhele ʻana o nā kaʻa mua me kēia ʻenekini i ka makahiki 1997. ʻO ka mākeke nui ʻo ʻEulopa, no ka mea, ʻaʻole i kaulana loa ka hui ma Asia a i ʻole ʻAmelika Hui Pū ʻIa, ʻoiai ke kūʻai aku nei ʻo Toyota i nā kaʻa nui loa ma laila.

Hoʻohana ʻia ka mīkini D4D i nā mīkini diesel Toyota, akā aia nā ʻokoʻa i kēia lula - ʻo ia ka hihia i ka wā e pili ana i nā ʻāpana kahi i hoʻohana ʻia ai ka ʻōnaehana D-CAT. ʻO kēia kahi hoʻomohala o ka ʻōnaehana D4D a ʻoi aku ka kiʻekiʻe o ke kaomi injection ma mua o ka ʻōnaehana kumu - 2000 bar, ʻaʻole ka pae mai 1350 a 1600 bar. 

ʻO nā ʻano hui like ʻole mai Toyota

ʻO kekahi o nā koho engine Toyota kaulana loa ʻo ia ka 1CD-FTV. Ua lako me ka Common Rail System. He 2 lita ka nui a me ka mana o 116 hp. Eia kekahi, ʻo ka hoʻolālā e loaʻa i ʻehā mau pahu i loko o ka laina, nā paia cylinder i hoʻoikaika ʻia a me kahi turbocharger geometry variable. Ua hana ʻia ka ʻāpana 1CD-FTV a hiki i 2007. Nā hiʻohiʻona o nā kaʻa i kau ʻia ai:

• Toyota Avensis?
• Corolla;
• Mamua;
• Corolla Verso;
• RAV4.

1ND-TV

He mea kūpono hoʻi e haʻi ʻia ʻo ka poloka 1ND-TV. He ʻenekini diesel turbocharged inline ʻehā pahu. He 1,4 lita kona neʻe ʻana a, e like me nā ʻāpana D-4D ʻē aʻe, ua hoʻohana ʻo ia i ka Common Rail direct fuel injection. I ka hihia o ka 1ND-TV, ʻo ka mana kiʻekiʻe loa he 68,88 a me 90 hp, a ʻo ka hui ponoʻī e hoʻokō me nā kūlana hoʻokuʻu EURO VI. ʻO nā hiʻohiʻona kaʻa i hoʻokomo ʻia me kēia ʻenekini:

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

1KD-FTV a me 2KDFTV

Ma ka hihia o ka 1KD-FTV, ke kamaʻilio nei mākou e pili ana i kahi mīkini diesel ʻehā-cylinder me ʻelua camshafts a me kahi turbine 3-lita me ka mana o 172 hp. Hoʻokomo ʻia ma nā kaʻa:

• Land Cruiser Prado;
• Heʻenalu Hilux;
• Fortuner;
• Hyas;
• Hilux.

Ma kekahi ʻaoʻao, ua paʻi ka lua o ka hanauna i ka mākeke ma 2001. ʻOi aku ka liʻiliʻi o ka neʻe ʻana a me ka mana kiʻekiʻe ma mua o kona mua: 2,5 lita a me 142 hp. Aia ʻo ia ma nā kaʻa e like me:

• Fortuner;
• Hilux;
• Hyas;
• Innova.

AD-FTV

Ua hoʻokomo ʻia ka ʻāpana o kēia moʻo i ka makahiki 2005. He turbocharger kona, a me ka neʻe ʻana o 2.0 lita a me ka mana o 127 hp. ʻO ka lua o ka hanauna, 2AD-FTV, ua hoʻolako ʻia me kahi ʻōnaehana kaʻa maʻamau D-4D, a me kahi turbocharger geometry variable me kahi neʻe o 2,2 lita. ʻO ka mana kiʻekiʻe loa mai 136 a 149 hp.

Ua hana pū ʻia ke kolu o ka hanauna o ka ʻāpana. Ua loaʻa iā ia ka inoa 2AD-FHV a loaʻa iā ia nā piezo injectors kiʻekiʻe. Ua hoʻohana pū nā mea hoʻolālā i ka ʻōnaehana D-CAT, ka mea i kaupalena i ka hoʻokuʻu ʻana i nā mea ʻino. ʻO 15,7:1 ka lākiō kōmi. ʻO ka nui o ka hana he 2,2 lita, a ʻo ka ʻāpana ponoʻī i hāʻawi i ka mana mai 174 a 178 hp. Ua hoʻohana ʻia nā ʻāpana i helu ʻia e nā mea nona nā kaʻa e like me:

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

1GD-FTV

Ma 2015, ua hoʻokomo ʻia ka hanauna mua o ka hui 1GD-FTV. He 2,8-lita inline me ka 175 hp DOHC engine. Loaʻa iā ia he 4 cylinders a me ka turbocharger geometry variable. No ka lua o ka hanauna, ua loaʻa i ka 2GD-FTV ka neʻe ʻana o 2,4 lita a me ka mana o 147 hp. Loaʻa i nā ʻano like ʻelua ka ratio hoʻoemi like o 15: 6. Ua hoʻokomo ʻia nā ʻāpana ma nā hiʻohiʻona e like me:

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

1 VD-FTV

ʻO kahi hana hou i ka mōʻaukala o nā ʻenekini Toyota ʻo ia ka hoʻokomo ʻana o ka ʻāpana 1 VD-FTV. ʻO ia ke ʻano V-like 8-cylinder diesel engine me ka neʻe ʻana o 4,5 lita. Hoʻolako ʻia me ka ʻōnaehana D4D, a me hoʻokahi a ʻelua paha turbocharger geometry variable. ʻO ka mana nui loa o ka hui turbocharged he 202 hp, a ʻo ka twin turbo he 268 hp.

He aha nā pilikia diesel maʻamau?

ʻO kekahi o nā hemahema maʻamau ka hemahema o nā injectors. ʻAʻole ʻoluʻolu ka ʻenekini Toyota D4D, a hoʻopau pū i ka nui o ka wahie, a i ʻole ka walaʻau nui.

Aia nā hemahema ma nā poloka 3.0 D4D. Hoʻopili lākou i ka pau ʻana o nā apo sealing, i hana ʻia me ke keleawe a kau ʻia ma nā mea hoʻokomo wahie. ʻO kahi hōʻailona o ka hana ʻino ʻia ka uahi keʻokeʻo e puka mai ana mai ka ʻenekini. Eia naʻe, e hoʻomanaʻo me ka mālama mau ʻana o ka ʻāpana a me ka hoʻololi ʻana i nā ʻāpana, pono e uku ka mīkini D4D iā ʻoe me ka hana maʻemaʻe a paʻa.
