5.7 hemi engine - ka nūhou nui loa e pili ana i ka ʻāpana

Aia ka mīkini 5.7 Hemi i ka hui o nā ʻāpana i hana ʻia e Chrysler. ʻO kahi hiʻohiʻona hiʻohiʻona o ka mīkini ʻo ia ka mea i hoʻolako ʻia me kahi keʻena puhi semicircular. Ua hoʻokomo mua ʻia ka huahana o ka hopohopo ʻAmelika i ka makahiki 2003 i ka manawa o ka mua o ka kaʻa Dodge Ram - ua hoʻohui ʻia me ka mīkini Magnum 5,9. Hōʻike mākou i ka ʻike nui loa e pili ana iā ia.

5.7 Hemi engine - ʻike kumu

ʻAʻole pili wale ʻo 2003 me ka mua o ka Dodge Rama, akā pū kekahi me ka ʻohana holoʻokoʻa o nā ʻenekini ʻekolu. ʻO ka mua he ʻenekini 8cc V5. cm / 654 l kapa inoa ʻo Eagle. Ua pani ia i ka poloka Magnum V3 i ʻōlelo ʻia ma ka hoʻomaka. Ua hoʻohana ʻia ka ʻenekini 5,7 Hemi i nā hiʻohiʻona Chrysler Dodge Durango, Charger, 8C, Magnum R/T, Jeep Grand Cherokee a me Commander.

ʻikepili ʻenehana ʻāpana Chrysler

ʻO ka ʻenekini hoʻomake maoli ʻehā-stroke he ʻewalu V-cylinders a me ʻelua kiwikā no ka cylinder. Hoʻokumu ʻia ka ʻōnaehana kaʻaahi valve ma ka manawa valve OHV. ʻO ka pahu 99,49 mm, hahau 90,88 mm, neʻe 5 cc.

I nā hiʻohiʻona mua - a hiki i ka makahiki 2009, ʻo ka compression ratio he 9,6: 1. Ma hope he 10,5:1. Hana ʻia ka mīkini 5.7 Hemi ma waena o 340 a me 396 hp. (254-295 kW) a me ka torque 08-556 Nm/3,950-4,400 He 6,7 l/l ka nui o ka aila. I ka huli ʻana, ua hiki ke kaumaha o ka ʻāpana i 254 kilokani.

Hoʻolālā ʻenekini 5.7 Hemi - he aha nā hoʻonā hoʻolālā i hoʻohana ʻia?

 Ua hoʻolālā hou ʻia ka ʻenekini 5.7 Hemi mai ka honua aʻe me kahi pahu pahu hao i hoʻolei ʻia hohonu a me kahi kihi pā 90 ° cylinder. Ma mua o 2008, ua ʻoi aku ka nui o nā apo 1,50/1,50/3/0mm, aʻo ka makahiki 2009 i hōʻike ʻia i ka pūʻolo 1,20/1,50/3,0mm. 

Ua hoʻoholo pū ka poʻe ʻenekinia e hoʻokomo i kahi crankshaft hao hoʻoheheʻe ʻia, i kau ʻia me ʻehā bolts ma kēlā me kēia bearing nui. Ua hoʻolālā pū ʻia ka camshaft ma kahi kiʻekiʻe e hoʻemi i ka lōʻihi o nā pana. No kēia kumu, ʻoi aku ka lōʻihi o ke kaulahao manawa a aia ma waena o nā panakō cylinder.

Hoʻolako pū ʻia ka Hemi 5.7 me nā poʻo poʻomanaʻo alumini crossflow, ʻelua pahu a me nā pahu kukui no kēlā me kēia cylinder. Ua hana ʻia hoʻi kahi keʻena palahalaha me nā papa ma nā ʻaoʻao ʻelua, kahi i hoʻonui ai i ka pono o ka mea hoʻokele. 

Nā mana e kōkua i ka hana ʻenekini maikaʻi

ʻO ka mana mua e nānā ai ʻo ia ka camshaft. ʻO ia ke kuleana no ka hana o ka intake a me ka exhaust valves mahalo i nā pushers i loaʻa i nā levers valve. ʻO nā ʻāpana koʻikoʻi pū kekahi me nā pūnāwai valve beehive a me nā tappet roller hydraulic.

Ua koho pū nā mea hoʻolālā i ka ʻōnaehana deactivation cylinder System Multi-Displacement System. ʻO kēia ka hopena i ka hoʻemi nui ʻana i ka hoʻohana ʻana i ka wahie a me ka hoʻokuʻu ʻana. Hoʻohana ka ʻenehana ma ka pani ʻana i ka wahie i ʻehā mau pahu - ʻelua i kēlā me kēia - a waiho ʻia nā kiwi hoʻokomo a me ka hoʻopau ʻana i pani ʻia, e kāohi ana i ke kahe ʻana o ka aila ma o nā mea hoʻokiʻekiʻe valve pākahi. Hoʻolako pū ʻia ka Hemi 5.7 me kahi throttle uila uila.

Hana ʻenekini 5.7 Hemi

I ka hihia o kēia mana mana, hiki ke kū mai nā pilikia me ka holo o 150-200 tausani km. Pili kēia i nā hana ʻino e pili ana i nā pūnāwai valve haʻihaʻi a i ʻole pipili a pōʻino i nā wili lever. Hoʻopili pinepine ʻia kēia me nā pilikia ignition a me kahi kukui Check Engine e hoʻomālamalama ʻia. ʻO ka haʻalele ʻana i kēia mau hōʻailona ma muli paha o ka hemahema o ka camshaft a i ʻole nā ​​mea metala i loko o ka ʻaila.

Pono au e koho i ka mīkini hemi 5.7?

ʻOiai ʻo kēia mau hemahema, ʻo ka ʻenekini 5.7 Hemi kahi ʻāpana kūpono maikaʻi a paʻa. ʻO kahi hiʻohiʻona e kōkua i kēia, he hoʻolālā maʻalahi - ʻaʻohe turbocharging i hoʻohana ʻia, i hoʻonui nui i kona ola lawelawe. ʻO ka ʻaoʻao haʻahaʻa, ʻoi aku ka kiʻekiʻe o ka wahie - a hiki i 20 lita no 100 km.

Me ka mālama mau ʻana a me ka hoʻololi ʻana o ka aila i kēlā me kēia 9600 km, e uku ka mīkini iā ​​ʻoe me ka hana paʻa a me ka haʻahaʻa haʻahaʻa haʻahaʻa. Pono e hoʻomanaʻo ʻia no ka hana kūpono o ka mana, pono e hoʻohana i ka aila me kahi viscosity o SAE 5W20.
