Nissan KA20DE engine
Ua ʻike ʻia ka mīkini ʻaila KA20DE me kahi poʻo māhoe māhoe i ka makahiki 1991 ma ke ʻano he pani no ka 2,0-lita Z20 (OHC NA20S i ka lua o ka hanauna Nissan Atlas). Hoʻohana ʻia kahi kaulahao i ka hoʻokele ʻana o kāna mīkini hoʻoili kinoea (manawa) (kahi ʻano kaulahao, i ʻike ʻia e ka pale ʻana i ka lole, ka hana leo ʻole, ka pale ʻana i nā loli koke o ka mahana, ʻoi aku ka hilinaʻi ma mua o nā kāʻei niho niho).
ʻO kona hoʻololi ʻana he mea maʻamau ia, e hana nui ana ma hope o ka holo ʻana ma mua o 300 tausani km (manaʻo ʻia e hana i kahi hoʻokolokolo pale ma hope o 100 tausani km). Hōʻike ʻia ka lole nui ma ke ʻano o:
- leo nui,
- hoʻokuʻu ʻana i ke koʻokoʻo
- ka hoʻololi ʻana o ka manawa o ka valve ma muli o ka lele ʻana o ke kaulahao e 1 - 2 niho (i hoʻonohonoho ʻia e nā diagnostics computer).
Pono e hoʻokō ʻia ka hoʻololi ʻana o ke kaulahao e like me ka hoʻokūkū pololei o nā māka manawa (ka hoʻokomo ʻana me nā hōʻailona ma nā loulou kaulahao e pili ana i nā hōʻailona o ka crankshaft a me nā camshafts hiki ke hoʻopau i ka mīkini kaʻa).
Mākaʻu
ʻO ka inoa ʻo KA20DE ke kū nei:
KA - Engine series (mai ka ʻāpana 4-cylinder in-line),
20 - Volume (2,0 lita),
D - ʻEnekini me ʻelua mau kāmele ma luna (DOCH),
E - Hoʻokomo wahie uila.
Hōʻike ʻia ka moʻo Nissan KA e nā ʻāpana KA20DE, KA24E a me KA24DE. Ma kaʻaoʻao maikaʻi, uaʻikeʻia e ka maʻalahi, ka hilinaʻi, ka lōʻihi, ma kaʻaoʻao maikaʻiʻole - kahi kiʻekiʻe kiʻekiʻe o ka wahie (no KA20DE, 100 - 12 lita o ka'olina i puhiʻia no 15 km ma keʻano kūlanakauhale, 8 - 9 lita ma ke alaloa. mode, i hui ʻia (10/15) - 10,5 l) a me ka paʻakikī o ka hoʻoponopono ʻana a me ka mālama ʻana (ʻoi loa i ka hoʻohālikelike ʻana me Toyota), i pili pū me kahi "hoʻopili" ʻoi loa o nā nodes ma lalo o ka pā.
'Ōlelo ka mea kaʻa i ka hilinaʻi kiʻekiʻe a me ka lōʻihi o ka mīkini - ʻaʻole hiki ke ʻike i ka ʻikepili hale hana, ma ka hoʻomaʻamaʻa, no ka laʻana, no ka Nissan Caravan, ʻoi aku ia ma mua o 300 tausani mau kilomita (e pili ana i ke kani ʻana e hoʻoneʻe i kahi 200. hp mai nā huila - hoʻokomo i kahi intake manifold, throttle dampers, camshafts me nā pūnāwai, cylinder head porting, māmā māmā pistons for a kiʻekiʻe (~ 11) compression ratio a me nā lāʻau hoʻohui, injectors ... - ua ʻoi aku ma mua o 350 tausani km. ).
ʻO ka helu engine e like me drive2.ru he 4+.
Nā kaʻa me ka ʻenekini KA20DE
Ua hoʻokomo ʻia ka ʻenekini hoʻoheheʻe kūloko (ICE) KA20DE ma nā hiʻohiʻona Nissan aʻe (ua hoʻopaʻa ʻia ka helu mai ka ʻaoʻao o ka exhaust manifold ma ka hui ʻana o ka mīkini a me ka pahu pahu):
- Atlas 10 2000 Super Low GE-SH4F23 (1999-2002), TC-SH4F23 (2003-2005), H2F23 (1999-2003);
- Caravan GE-VPE25 (2001 г.), LC-VPE25 (2005 г.);
- Datsun GC-PD22 (1999 - 2001);
a me Isuzu COMO GE-JVPE25-S48D 2001 - 2003, Isuzu ELF ASH2F23, Isuzu Fargo JVPE24.
Hōʻike ʻia nā kaʻa āpau i helu ʻia e kahi ʻano haʻahaʻa haʻahaʻa loa o nā mea ʻino i loko o nā kinoea hoʻopau - ua lako ka ʻenekini me kahi ʻōnaehana LEV (E-LEV index - ʻoi aku ka maʻemaʻe o 50% ma mua o 2000, 2005 mau kūlana). Holo ka ʻāpana i ka hui ʻana o ka ea a me ka ʻaila me ka ratio o 40:1.
Nāʻike kiko'ī
Hāʻawi ʻia nā ʻāpana ʻenehana nui ma ka papa:
| Inoa | waiwai |
|---|---|
| Poʻo pahu | DOHC, 4 mau kinikini |
| Paukūʻolokaʻa mea | hao hao |
| Ka nui o ka mīkini, kenimika 3 | 1998 |
| Mea hoʻohuihui | intake manifold/carburetor injection |
| Ka mana enekini, h.p. (kW) | 120 (88) ma 5200 rpm |
| Luuluu, mm | 86 |
| Pāhona piston, mm | 86 |
| ʻO ka torque kiʻekiʻe loa, Nm (kg-m) / rpm | 171 (17) / 2800 |
| Kaohi ʻana | 9.500:1 |
| Kahi | 92, 95 |
| Crankshaft bearings, pcs. | 5 |
| Manawa | kaulahao |
ʻO ka nui o ka aila curled he 4,1 lita. Manaʻo ʻia ka hoʻololi ʻana ma hope o 7 - 500 km (ma kahi o 15 g no 000 km). Pili loa ka mīkini i ka maikaʻi - pono ʻoe e koho i ke kumu mai ka moʻo "no ka ʻaila" me ka viscosity o 500W-1000, 5W-30, 5W-40, 10W-30.
Inā hāʻule ka KA20DE, hiki iā ʻoe ke hoʻonui i ka 2.0-lita NP300 me 114 hp, i hana ʻia mai 2008 a hiki i kēia lā.
