Fiat 1.9 JTD engine - ka ʻike nui loa e pili ana i ka hui a me ka ʻohana Multijet

No ka ʻohana Multijet ka mīkini 1.9 JTD. He huaʻōlelo kēia no ka hui o nā ʻenekini mai Fiat Chrysler Automobiles, e komo pū ana me nā ʻāpana turbodiesel me ka hoʻokele wahie pololei - Common Rail. Ua hoʻokomo pū ʻia ke kumu hoʻohālike 1.9-lita ma nā kaʻa Alfa Romeo, Lancia, Cadillac, Opel, Saab a me Suzuki.

ʻIke kumu e pili ana i ka mīkini 1.9 JTD

I ka hoʻomaka ʻana, pono e hoʻomaʻamaʻa iā ʻoe iho me ka ʻike kumu e pili ana i ka ʻāpana drive. Ua hoʻohana mua ʻia ka 1.9 JTD inline ʻehā-cylinder engine ma 156 Alfa Romeo 1997. ʻO ka ʻenekini i hoʻokomo ʻia ma luna ona ka mana o 104 hp. a ʻo ia ke kaʻa kaʻa mua i hoʻolako ʻia me ka ʻenekini diesel me kahi ʻōnaehana hoʻoheheʻe wahie pololei.

I kekahi mau makahiki ma hope mai ua hoʻokomo ʻia nā ʻano ʻē aʻe o ka 1.9 JTD. Ua hoʻokomo ʻia lākou ma Fiat Punto mai 1999. He 79 hp ka mana o ka mīkini. Ua hoʻohana pū ʻia ka mīkini i nā hiʻohiʻona ʻē aʻe o ka mea hana Italia - Brava, Bravo a me Marea. ʻO nā mana ʻē aʻe o ka ʻāpana i ka papa inoa o ka mea hana i loaʻa kēia mau mana 84 hp, 100 hp, 104 hp, 110 hp. a me 113 hp 

ʻIkeʻike loea o ka mana mana Fiat

Ua hoʻohana kēia ʻano ʻenekini i kahi poloka hao hoʻoheheʻe ʻia ma kahi o 125 kg a me ke poʻo cylinder aluminika me kahi camshaft i hoʻolako ʻia me nā kiwi hana pololei. ʻO ka neʻe ʻana he 1,919 cc, 82 mm ka nui, 90,4 mm ka hahau, ka lākiō hoʻopaʻa 18,5.

He ʻōnaehana kaʻa kaʻa maʻamau maʻamau ka lua o ka ʻenekini a loaʻa i loko o ʻehiku mau mana mana like ʻole. ʻO nā mana āpau, koe wale nō ka ʻāpana 100 hp, ua lako me ka turbocharger geometry variable. Aia ka 8-valve version 100, 120 a me 130 hp, aʻo ka 16-valve version he 132, 136, 150 a me 170 hp. He 125 kilokani ke kaumaha o ka pale.

ʻO ka hōʻailona ʻana i nā kaʻa o nā kaʻa ʻē aʻe a ma luna o nā kaʻa i kau ʻia ai

Hiki ke kapa inoa ʻia ka mīkini 1.9 JTD. Ua hilinaʻi ia i nā hoʻoholo kūʻai aku a nā mea hana i hoʻohana iā ia. Ua hoʻohana ʻo Opel i ka pōkole CDTi, ua hoʻohana ʻo Saab i ka inoa TiD a me TTiD. Ua kau ʻia ka ʻenekini ma luna o nā kaʻa e like me:

• Alfa Romeo: 145,146 147, 156, 159, XNUMX, GT;
• Fiat: Bravo, Brava, Croma II, Doblo, Grande Punto, Marea, Multipla, Punto, Sedici, Stilo, Strada;

• Ihe: Delta, Vesra, Musa;
• Opel: Astra N, Signum, Vectra S, Zafira B;
• Saab: 9-3, 9-5;
• Suzuki: SX4 a me DR5.

ʻElua papa turbo - ʻenehana twin-turbo

Ua hoʻoholo ʻo Fiat mai ka makahiki 2007 e hoʻohana ʻo ia i kahi ʻano hou turbocharged ʻelua. Ua hoʻomaka ka hoʻohana ʻana i nā turbos māhoe i nā mana 180 hp. a me 190 hp me ka torque kiʻekiʻe loa o 400 Nm ma 2000 rpm. Ua kau ʻia ka mua o nā ʻāpana ma nā kaʻa o nā ʻano like ʻole, a ʻo ka lua wale nō ma nā kaʻa o ka hopohopo Fiat.

ʻO ka hana o ka mea hoʻokele - he aha ka mea e nānā ai?

Hana maikaʻi nā kaʻa i hoʻolako ʻia me kēia mana mana. Ua maikaʻi loa ka hana ʻana i ka nui o nā hiʻohiʻona i ke kūlana ʻenehana maikaʻi loa ʻoiai nā makahiki i hala. 

ʻOiai nā loiloi maikaʻi, ʻo ka mīkini 1.9 JTD he nui nā drawbacks. Hoʻopili kēia i nā pilikia me ka sunroof, exhaust manifold, EGR valve, a i ʻole ka lawe lima. E aʻo hou e pili ana i nā hewa maʻamau. 

Hana hewa ʻole ʻo Flap 

I loko o nā ʻenekini diesel me 4 valves no ka cylinder, hoʻokomo pinepine ʻia nā swirl flaps - i loko o kekahi o nā awa komo ʻelua o kēlā me kēia cylinder. Nalo nā dampers i ko lākou neʻe ʻana ma muli o ka haumia o ka paipu inlet turbodiesel. 

Hana ʻia kēia ma hope o kekahi manawa - paʻa a haki paha ka throttle. ʻO ka hopena, ʻaʻole hiki ke hoʻolōʻihi ʻia ka mea hoʻokele i ʻoi aku ma mua o 2000 rpm, a ma nā hihia koʻikoʻi hiki ke wehe a hāʻule i ka cylinder. ʻO ka hoʻonā i ka pilikia ke hoʻololi i ka manifold intake me kahi mea hou.

Pilikia me ka exhaust manifold, EGR a me alternator

Hiki ke hoʻololi ʻia ka intake manifold ma muli o nā wela kiʻekiʻe. Ma muli o kēia, hoʻopau ʻo ia i ke komo ʻana i ke poʻo cylinder. ʻO ka pinepine, hōʻike ʻia kēia ma ka ʻohi ʻana o ka soot ma lalo o ka ʻohi, a me kahi ʻala ʻike o ka pau ʻana o ke kaʻa.

Hoʻokumu ʻia nā pilikia EGR ma muli o kahi valve paʻa. A laila hele ke kalaiwa i ke ʻano pilikia. ʻO ka hopena e hoʻololi i ka mea kahiko me kahi mea hou.

Loaʻa nā hemahema o ka mea hana i kēlā me kēia manawa. Ma kēia kūlana, ho'ōki ia i ka hoʻouka maʻamau. ʻO ke kumu maʻamau he diode i loko o ka mea hoʻoponopono voltage. Pono ke pani.

Hana ʻino ʻia ka lawe lima lima

I ka hana ʻana o ka mīkini 1.9 JTD, hāʻule pinepine ka lawe lima. ʻOiai ʻaʻole ia he mea pololei o ka ʻenekini, ua pili kāna hana me ka mea hoʻokele. ʻO ka pinepine, hāʻule nā ​​bearings o ka ʻelima a me ke ono. ʻO kahi hōʻailona ʻaʻole holo pono ka ʻōnaehana ʻo ka walaʻau a me ka pahū. Ma nā ʻanuʻu aʻe, hiki ke nalowale ka alignment o ka pahu hoʻouna a pau ka pane ʻana o ka 5 a me 6.

Hiki ke kapa ʻia ka mīkini 1,9 JTD i hilinaʻi?

Hiki i kēia mau pilikia ke hoʻonāukiuki, akā ma ka ʻike ʻana aia lākou, hiki iā ʻoe ke pale iā lākou. He mea pono e hoʻomaopopo, ma waho aʻe o nā pilikia i luna, ʻaʻohe hewa koʻikoʻi i ka wā o ka hana ʻana o ka mīkini 1.9 JTD, hiki ke alakaʻi, no ka laʻana, i kahi hoʻoponopono nui o ka mana. No kēia kumu, ʻo ke kaʻa mai Fiat - me ka ʻole o nā hemahema hoʻolālā koʻikoʻi, hiki ke wehewehe ʻia he hilinaʻi a paʻa.
