ENGINE PAHA: ʻEnekini No Hyundai D4BH
HOOLAHA HUA
ʻO ka 2.5-lita Hyundai D4BH diesel engine i hui ʻia e ka manaʻo Korea mai 1997 a ʻike ʻia mai nā Galloper a me Terrakan SUVs, a me nā minibus H1 a me Starex. ʻO kēia mana mana he clone o ka Mitsubishi 4D56 turbocharged diesel engine me kahi intercooler.
I ka makahiki 1997, ua ʻike ʻia kahi mīkini turbocharged me kahi intercooler i ka ʻohana Hyundai diesel.
ʻO ka ʻoiaʻiʻo he clone wale nō ia o ka Mitsubishi 4D56 prechamber turbodiesel kaulana.
Aia kahi pahu pahu hao me ke poʻo 8-valve alumini me ka ʻole o nā mea hoʻokiʻekiʻe hydraulic,
he kaʻa kāʻei manawa a me ka pahu pahu wahie kāʻei hoʻokele, a me ka poloka o nā mea kaulike me
kona kaei ponoi. Ua hoʻokomo ʻia nā turbines ma luna o ia mea, akā ʻo ka pinepine ʻo Mitsubishi TD04-11G-4
a i ʻole Garrett GT1749S.
He nui nā hiʻohiʻona a me nā hoʻololi ʻana o kēia mīkini diesel, ʻokoʻa ka nui o ia mau mea.
Aia pū kēia ʻohana i nā diesel: D4BA, D4BB a me D4BF.
Ua hoʻokomo ʻia ka ʻenekini ma:
Hyundai Galloper 2 (JK) ma 1997 – 2003;
Hyundai Starex 1 (A1) ma 1997 – 2007;
ʻO Hyundai Terracan 1 (HP) ma 2001 - 2006.

Nā hemahema o ka mīkini Hyundai D4BH
1. ʻOiai ʻo ka mīkini i hoʻolako ʻia me ka Bosch VE injection pump o ke ʻano hoʻolaha, ʻo nā pilikia ākea o ia mau mīkini diesel e pili ana i nā hemahema o ka ʻōnaehana wahie. Ma muli o ka hoʻohana ʻana i ka wahie haʻahaʻa haʻahaʻa, pau nā ʻāpana mīkini o ka pauma wahie kiʻekiʻe a ʻaʻole hoʻomaka maikaʻi ka ʻāpana i ka wā wela. No ke kumu like, hoʻololi ʻia nā nozzles injector.
2. E like me nā lula, ua hoʻololi ʻia ke kāʻei manawa i kēlā me kēia 90,000 km, akā pinepine ka haki ʻana ma mua. ʻO nā mea āpau no ka mea pono e hoʻopaʻa ʻia i kēlā me kēia 30,000 km, akā nui ka poʻe e nānā ʻole i ka manual. Eia kekahi, haki pinepine ke kāʻei kaulike a laila ʻū ʻia ma lalo o ke kāʻei manawa, a haki pū kekahi. Maikaʻi i ka nui o nā hihia e haki wale i ka rocker.
3. ʻAʻole makemake ʻo Diesel o kēia laina i ka overheating a ʻoki pinepine ka gasket iā lākou, a ʻaʻole lawa ka hoʻololi ʻana i ka gasket, pono ʻoe e wili i nā mea pili. I nā hihia kiʻekiʻe loa, ʻike ʻia nā māwae ma waena o nā pahu a puni nā keʻena mua. No laila, ʻuʻuku loa a pipiʻi nā poʻo cylinder no ia mau ʻenekini.
4.We papa inoa i nā haʻihaʻi i koe ma ka papa inoa hoʻokahi: piʻi mau ka aila mai nā sila aila, ʻoki pinepine i ke kī crankshaft, kahi e hoʻōki koke ai i ka hoʻokele o nā mea hoʻopili, a me ka neʻe lōʻihi loa i nā haʻahaʻa haʻahaʻa, hiki i ka crankshaft ke maʻalahi. pohā. A mai poina e pili ana i ka hoʻoponopono ʻana o ka valve clearance a i ʻole e puhi wale lākou.
