Jet engine 1.4 t - he aha ka pono e ʻike?

I ka hana ʻana i kēia hanauna, ua ʻōlelo ʻo Fiat e hui pū ka mīkini 1.4 T Jet (e like me nā ʻāpana ʻē aʻe o kēia ʻohana) i ka moʻomeheu kiʻekiʻe o ka hana a me ka hoʻokele waiwai. ʻO ka hoʻonā ʻana i kēia pilikia he hui hou o ka turbocharger a me ka hoʻomākaukau ʻana i ka hui ʻana. Ke hoʻolauna nei i ka ʻike nui loa e pili ana i ka 1.4T Jet mai Fiat!

Jet engine 1.4 t - ka ʻike kumu

Loaʻa ka ʻāpana i ʻelua mau mana - ʻo ka mea nāwaliwali ka mana o 120 hp, a ʻo ka mea ikaika he 150 hp. ʻO nā hiʻohiʻona i hoʻomohala ʻia e nā mea hoʻolālā o Fiat Powertrain Technologies he hoʻolālā e pili ana i kahi ʻenekini kaulana ʻē aʻe - 1.4 16V Fire. Eia naʻe, ua hoʻolālā hou ʻia lākou ma muli o ka pono e hoʻokomo i kahi turbo.

Hoʻokaʻawale ʻia ka mīkini jet 1.4 T e ka ʻoiaʻiʻo e hāʻawi i ka mana nui a ma ka manawa like ka hoʻohana ʻana i ka wahie. Hōʻike pū ia i kahi ākea rev ākea a maikaʻi loa ka pane hoʻololi ʻana. 

ʻikepili ʻenehana ʻenehana Fiat

ʻO ka ʻenekini 1.4 T Jet he ʻenekini DOHC inline-ʻehā me 4 kiwi no kēlā me kēia cylinder. ʻO nā mea hana o ka ʻāpana e pili ana i ka uila uila, multi-point fuel injection, a me ka turbocharging. Ua hoʻokuʻu ʻia ka mīkini i ka makahiki 2007 a hāʻawi ʻia e like me 9 mau koho mana: 105, 120, 135, 140 (Abarth 500C), 150, 155, 160, 180 a me 200 hp. (Abarth 500 Assetto Corse). 

ʻO ka 1.4 t jet engine he kāʻei kāʻei a me ka hoʻoheheʻe wahie indirect. Pono e hoʻomaopopo ʻia ʻaʻole nui nā mea hoʻolālā paʻakikī i ka ʻāpana - koe wale nō ka turbocharger, kahi e maʻalahi ai ka mālama. 

Nā hiʻohiʻona o ka hoʻolālā ʻana o kahi mīkini jet 1.4 tons.

I ka hihia o ka 1.4 T Jet, ua hana ʻia ka pahu cylinder i ka hao hao a loaʻa iā ia ka ikaika mechanical kiʻekiʻe. ʻO ka ʻaoʻao haʻahaʻa o ka pahu pahu i hana ʻia me ka alumini alumini die-cast a ʻo ia kahi ʻāpana o ka hoʻokumu ʻana i ka ukana me ka crankcase nui. 

Hoʻopili ia i nā ukana i hana ʻia e ka crankshaft a hana pū i kahi lālā paʻa me ka pahu pahu ma o ka lima pane. Hana pū ia i ka hana o ka hoʻopaʻa ʻana i ke kau ʻana o ke kumu axle ʻākau. Hoʻokomo pū ka ʻenekini 1.4 T i ka crankshaft kila ʻewalu kaulike, kahi crankshaft paʻakikī induction a me nā bearings ʻelima.

ʻO ka hui pū ʻana o kahi turbocharger me kahi intercooler a me kahi valve bypass - nā ʻokoʻa mai ka mana aggregate

Ua hoʻomohala kūikawā ʻia kēia hui ʻana no nā huahana ʻelua o ka mīkini 1.4 T-Jet. Eia naʻe, aia kekahi mau ʻokoʻa ma waena o kēia mau ʻano. He aha lākou e pili ana? 

1. No ka 'enekini li'ili'i ikaika, e hō'oia 'ia e ka huila turbine geometry ka pi'i ki'eki'e ma nā torque ki'eki'e loa. Mahalo i kēia, hiki ke hoʻohana ʻia ka mana piha o ka ʻāpana. 
2. I ka huli ʻana, i ka mana ikaika loa, ua hoʻonui ʻia ke kaomi ma muli o ka overboost, kahi e hoʻonui ai i ka torque i kahi kiʻekiʻe o 230 Nm me ka pani ʻana o ka wastegate. No kēia kumu, ʻoi aku ka maikaʻi o ka hana o nā ʻāpana haʻuki.

Hana Hana - Nā pilikia maʻamau

ʻO kekahi o nā ʻāpana hewa loa o ka mīkini 1.4 T Jet ʻo ia ka turbocharger. ʻO ka pilikia maʻamau he hihia māwae. Hōʻike ʻia kēia e kahi puʻupuʻu hiʻohiʻona, uahi mai ka ʻūhā a me ka nalowale ʻana o ka mana. He mea pono e hoʻomaopopo ʻia pili kēia i nā ʻāpana turbine IHI - i lako me nā ʻāpana Garrett, ʻaʻole lākou i hemahema.

ʻO nā pilikia pilikia pū kekahi me ka nalowale o ka mea hoʻomaha. Hiki ke ʻike ʻia kahi hana ʻino ke ʻike ʻia nā kiko ma lalo o ke kaʻa. Aia kekahi mau hewa e pili ana i ka leakage o ka aila ʻenekini - ʻo ke kumu he hewa paha o ka bobbin a i ʻole sensor. 

Pehea e hana ai me nā pilikia ʻenekini 1.4 T-Jet?

No ka hoʻoponopono ʻana i ke ola pōkole o ka turbocharger, kahi hopena maikaʻi e hoʻololi i nā bolts hānai aila me ka turbine aila. ʻO kēia ma muli o ka ʻoiaʻiʻo i loko o kēia mea aia kahi kānana liʻiliʻi e hōʻemi i ka lubrication o ka rotor i ka hihia o ka nalowale o ka paʻa. Eia naʻe, inā pilikia me ka heatsink, ʻoi aku ka maikaʻi o ka hoʻololi ʻana i ka ʻāpana holoʻokoʻa. 

ʻOiai kekahi mau hemahema, hiki ke loiloi ʻia ka mīkini jet 1.4 T ma ke ʻano he ʻāpana hana maikaʻi. ʻAʻohe hapa o nā ʻāpana ʻokoʻa, hiki ke kūpono me ka hoʻonohonoho LPG a hāʻawi i ka hana maikaʻi - no ka laʻana, i ka hihia o ka Fiat Bravo, mai 7 a 10 kekona a 100 km / h.

I ka manawa like, he mea waiwai loa ia - ma kahi o 7/9 lita no 100 km. ʻO ka lawelawe maʻamau, ʻo ke kāʻei manawa i kēlā me kēia 120 km. km, a i ʻole kahi lele lele lele i kēlā me kēia 150-200 tausani km, pono e lawa i ka hoʻohana ʻana i ka ʻāpana mokulele 1,4-t no ka manawa lōʻihi a hoʻopaʻa i ka mile mile kiʻekiʻe.
