Enekinia Nissan SR20De

ʻO ka ʻenekini Nissan SR20De he ʻelele o ka ʻohana nui o nā hui mana ʻaila o kahi hui Iapana, i hui pū ʻia e ka SR index. ʻO ka nui o kēia mau mīkini mai 1,6 a 2 lita.

ʻO ka hiʻohiʻona ʻenehana nui o kēia mau kaʻa he poʻo cylinder aluminika a me ke kila, ʻoiaʻiʻo, cylinder block. Ua hana ʻia kēia mau mīkini hoʻoheheʻe kūloko (ICE) mai 1989 a 2007.

Hōʻike nā helu i ka mākaʻikaʻi ʻana i ka nui o ka mīkini. ʻO ia hoʻi, inā ʻo SR18Di ka inoa o ka mīkini, a laila ʻo 1,8 lita kona leo. No laila, no ka mīkini SR20De, ua like ka neʻe ʻana o ka mīkini me ʻelua lita.

ʻO nā ʻenekini SR series a, ʻo ia hoʻi, nā mīkini ʻelua-lita o kēia pūʻulu, ua hoʻokomo ʻia ma kahi papa inoa nui loa o nā kaʻa kaʻa i hana ʻia e Nissan i nā makahiki 90 "zero".

ʻO ka mōʻaukala o ka mīkini Nissan SR20De

Ma waena o nā mana mana āpau o ka SR series, ʻo ka SR20De ka mea kaulana loa, a ʻōlelo paha kekahi i kaulana i ko mākou ʻāina. Ua hoʻokomo ʻia kēia mau kaʻa ma ka ʻewalu o ka hanauna Nissan Bluebird model, kahi i lawe ikaika ʻia, mua i ka USSR, a laila i Rūsia, e nā mea kūʻai hina a i ʻole nā ​​​​mea distillers.

Ma mua o ka hiki ʻana mai o kēia mau ʻenekini, i ka ʻāpana o nā ʻāpana mana 2-lita, ua hana nā Iapana i CA20. Ua kaumaha loa keia enegini, ma ke ano o ka nuipa, oiai, o kona poloka a me kona poo he hao hoolei. I ka makahiki 1989, ua hoʻokomo ʻia nā alumini SR20s māmā ma Bluebirds, i loaʻa ka hopena maikaʻi i nā hiʻohiʻona ʻelua o nā kaʻa a me kā lākou pono. Eia kekahi, no ka hoʻokele waiwai a me ka hana ʻoi aku ka maikaʻi, ua loaʻa i kēia mau ʻenekini hoʻopau i loko kahi injector multi-point a me ʻehā kiwi no kēlā me kēia cylinder.

Mai ka hoʻomaka ʻana o ka hana ʻana, ua hoʻokomo ʻia kahi uhi ʻulaʻula ma luna o kēia mau mana. No kēia, ua loaʻa i nā kaʻa ka inoa SR20DE Red top High port. Ua kū kēia mau ICE ma ka laina hui a hiki i ka makahiki 1994, i ka wā i pani ʻia ai lākou e SR20DE Black top Low port engines.

Mai kona mua, ma kahi o ka uhi ʻeleʻele ʻeleʻele, ua ʻike ʻia kēia mana mana e nā ala komo hou o ke poʻo cylinder (poʻo cylinder). ʻO kahi camshaft 240/240 hou (ua loaʻa i ka mua he 248/240 camshaft) a me kahi ʻōnaehana hoʻopau hou me nā paipu 38mm (ʻo ka SR20DE Red top High port he 45mm exhaust pipes). Ua kū kēia mīkini ma ka laina hui a hiki i ka makahiki 2000, ʻoiai ʻaʻole i loko o kahi kūlana i hoʻololi ʻole ʻia, i ka makahiki 1995, ua ʻike ʻia kahi camshaft hou 238/240 ma ka kaʻa.

I ka makahiki 2000, ua pani ʻia ka SR20DE Black top Low port e kahi SR20DE roller rocker ICE. ʻO nā hiʻohiʻona nui o kēia pūnaehana he mau wili wili a me nā puna wai hoʻihoʻi hou. ʻO nā hoʻololi ʻē aʻe e ʻike ʻia he pistons i hoʻololi iki ʻia, kahi crankshaft māmā a me kahi manifold intake pōkole. Ua hana ʻia kēia hoʻololi a hiki i 2002. Ma hope o kēlā, ua hoʻopau ʻia nā ʻenekini lewa SR20DE. Eia nō naʻe, ua hoʻomau ʻia nā mana turbocharged o kēia mīkini a e kūkākūkā ʻia ko lākou mōʻaukala ma lalo nei.

ʻO ka mōʻaukala o nā ʻenekini SR20DET turbocharged

Aneane i ka manawa like me ka mīkini aspirated maoli, ua puka mai kona mana turbocharged, nona ka inoa SR20DET. ʻO ka mana mua, ma ka hoʻohālikelike me ka ʻenekini kūlohelohe maoli, ua kapa ʻia ʻo SR20DET Red top. Ua hana ʻia kēia ICE, e like me kāna ʻano lewa, a hiki i 1994.

Ua loaʻa i kēia kaʻa ka turbine Garrett T25G, kahi i hana ai i ke kaomi o 0,5 bar. ʻO kēia hoʻoikaika i hiki ke hoʻomohala i ka mana o 205 hp. ma 6000 rpm. ʻO ka torque o ka ʻenekini hoʻopau i loko he 274 Nm ma 4000 rpm.

I mea e hoʻopakele ai i ke ola o ka mīkini, ua hoʻemi ʻia ka ratio hoʻoemi i 8,5 a ua hoʻoikaika ʻia nā koʻokoʻo pili.

E like me kēia mana mana, i ka makahiki 1990 ua ʻike ʻia kahi mana ikaika loa, me ka mana o 230 hp. ma 6400 rpm a me ka torque o 280 Nm ma 4800 rpm. Ua ʻokoʻa ʻo ia mai kona mea i hana mua ʻia e kahi ʻē aʻe Garrett T28 turbine, nāna i hana i ke kaomi o 0,72 bar. Eia kekahi, ma waho aʻe o kēia, ua hana ʻia nā hoʻololi hou i ka mana. Ua loaʻa iā ia kahi camshaft 248/248 ʻē aʻe, nā injectors wahie ʻē aʻe me ka mana o 440 cm³ / min, nā nozzles aila ʻē aʻe, ka crankshaft, nā koʻokoʻo pili a me nā poʻo cylinder poʻo i hoʻoikaika ʻia.

E like me ka mana lewa, ua puka mai ka hanauna hou o kēia mana mana i ka makahiki 1994. Ua loaʻa iā ia ka inoa ʻo Nissan SR20DET Black top. Ma waho aʻe o ka uhi ʻeleʻele ʻeleʻele, i lilo i mea hōʻailona o kēia ʻenekini, ua loaʻa pū kekahi lambda probe a me nā pistons hou. Eia hou, ua hoʻololiʻia nā ala komo komo a me waho, a ua hoʻololiʻia ka hoʻonohonoho kamepiula ma luna o ka papa.

Ua hoʻokuʻu ʻia kahi mana ʻokoʻa a ʻoi aku ka ikaika o kēia ʻenekini no ke kaʻa haʻuki Nissan S14 Silvia. He ʻenekini 220 hp kēia kaʻa. ma 6000 rpm a me ka torque o 275 Nm ma 4800 rpm.

Eia nō naʻe, ua hoʻokomo ʻia ka mana ʻoi loa o ka mana mana ma ka hope, ʻehiku o ka hanauna ʻo Sylvia, nāna i lawe i ka index S15. ʻO ka mīkini ma kēia kaʻa he Garrett T28BB turbo me kahi intercooler i hoʻomohala i kahi kaomi o 0,8 bar. Eia kekahi, ua lako ia me ka mono nozzle me ka mana o 480 cm³ / min. Ma hope o kēia hoʻololi hou ʻana, ua hoʻomohala ka ʻenekini hoʻomohala kūloko i ka mana o 250 hp. ma 6400 rpm a he torque o 300 Nm ma 4800 rpm.

ʻElua mau mana hou aʻe o ka SR20DET ma luna o ke kaʻa kaʻa kaʻa ʻike liʻiliʻi ʻo Nissan Avenir. No kēia mīkini, ua kūkulu ʻia ʻelua mau mana, ʻelua-lita me ka mana o 205 a me 230 hp i ka manawa hoʻokahi. Ua kapa ʻia kēia mau kaʻa i kapa ʻia ʻo Nissan SR20DET Silver top.

Eia naʻe, ua hoʻokomo ʻia ka mana ikaika loa o ka mīkini Nissan SR20, i ka makahiki 21st, ma ka crossover Nissan X-Trail GT kaulana. 'Oia'i'o, 'a'ole i kū'ai 'ia kēia mana o ka crossover ma Rusia.

No laila, ua kapa ʻia kēia mana ʻo SR20VET a ua kau ʻia ma ka hanauna mua X-Trails no ka mākeke Iapana. ʻO kēia mana, e like me ka hanauna mua o ka crossover, i hana ʻia mai 2001 a 2007. Ua hoʻomohala kēia ICE i ka mana o 280 hp. ma 6400 rpm a he torque o 315 Nm ma 3200 rpm. ʻO nā hiʻohiʻona hoʻolālā o kēia mana mana, pono e ʻike i nā camshafts 212/248 a me ka turbine Garrett T28, me ka hoʻoikaika ʻana o ka 0,6 bar.

I ka hopena o ka moʻolelo e pili ana i ka mōʻaukala o ka mīkini Nissan SR20De, pono e ʻōlelo ʻia ua lilo ia i mea maʻamau i waena o ka moʻo SR holoʻokoʻa.

ʻO ka hilinaʻi kaʻa

Ma kahi kaʻawale, pono e ʻōlelo ʻia e pili ana i ke kumu waiwai o kēia kaʻa, no ka mea, ʻo ka hapa nui o nā mana o ia manawa, i hana ʻia ma ka ʻāina o ka lā hikina, aneane mau loa. ʻO kā lākou hui piston, maʻalahi, hele i ka hapalua miliona kilomita a ʻoi aku paha. ʻO ia hoʻi, ʻoi aku ka lōʻihi o kēia mau ʻenekini hoʻopau i loko ma mua o ke kumu waiwai o nā kino kaʻa i kau ʻia ai.

ʻO nā pilikia koʻikoʻi liʻiliʻi ma kēia mau ʻāpana mana, ʻike ʻia ka hemahema mua o ka mea hoʻokele idle speed a me ka ʻike ea kahe nui. Ke ulu nui nei kēia mau pilikia ma muli o ka haʻahaʻa o ka wahie ma ko mākou ʻāina.

ʻAe, ma kahi o ka hilinaʻi kūʻokoʻa o ka pūʻulu piston, ʻo ka pōmaikaʻi o kēia mau kaʻa ʻo ka nele o ke kāʻei i ka mīkini mīkini manawa. Loaʻa i kēia mau kaʻa ka pahu kaulahao camshaft, a ʻo ke kaulahao, ma ke ʻano he kumu waiwai o 250 - 300 mau kilomita.

He aha ke ʻano o ka ʻaila e ninini ai

E like me nā kaʻa holoʻokoʻa o ka hui, ʻo Nissan SR20 ka mea maikaʻi ʻole i ka ʻaila i hoʻohana ʻia. Hiki ke hoʻohana ʻia nā ʻaila API ma kēia ʻenekini:

• 5W-20
• 5W-30
• 5W-40
• 5W-50
• 10W-30
• 10W-40
• 10W-50
• 10W-60
• 15W-40
• 15W-50
• 20W-20

No ka mea hana ʻaila, ʻōlelo ka hui Iapana e hoʻohana i kā lākou ʻaila ponoʻī. A he manaʻo nui ka hoʻohana ʻana iā lākou. ʻO ka ʻoiaʻiʻo ʻaʻole i loaʻa nā ʻaila Nissan no ke kūʻai manuahi ʻana, aia wale nō i nā mea kūʻai aku o ka ʻoihana a me kā lākou hoʻohana ʻana e hōʻoiaʻiʻo e hoʻopiha ʻoe i ka aila maoli maoli, ʻo ka hōʻailona ʻana ma ka canister e pili ana i kāna mau mea.

ʻAe, no ka ʻike ma ka pahu, a laila:

• Strong Save X - ka inoa o ka aila;
• 5W-30 - kona helu ʻana e like me ka API;
• SN - ʻo ka huahelu mua ma kēia māka e hōʻike ana i nā ʻenekini no kēia ʻaila;

1. S - e hōʻike ana he aila kēia no nā ʻenekini ʻaila;
2. C - no ka diesel;
3. N - hōʻike i ka manawa o ka hoʻomohala ʻana o ka ʻaila. ʻOi aku ka nui o ka leka mai ka hua mua "A", ʻo ia ka mea hou aku. No ka laʻana, ʻike ʻia ka ʻaila "N" ma mua o ka ʻaila me ka leka "M".

Ka papa inoa o nā kaʻa i kau ʻia ai kēia ʻenekini

ʻO ka ʻenekini Nissan SR20De kekahi o nā ʻāpana mana maʻamau o ka hui Iapana. Ua hoʻokomo ʻia ma kahi papa inoa lōʻihi o nā hiʻohiʻona:
