Jet enjene 1.4 t - ke eng eo u lokelang ho e tseba?

Ha a theha moloko ona, Fiat e boletse hore enjene ea 1.4 T Jet (joaloka lihlopha tse ling tsa lelapa lena) e tla kopanya setso se phahameng sa mosebetsi le ho khanna moruo. Tharollo ea bothata bona e bile motsoako o mocha oa turbocharger le tokiso ea motsoako o laoloang. Ho hlahisa tlhahisoleseding ea bohlokoa ka ho fetisisa mabapi le 1.4T Jet ho tloha Fiat!

Jet enjene 1.4 t - tlhahisoleseding ea motheo

Sehlopha se fumaneha ka liphetolelo tse peli - e fokolang e na le matla a 120 hp, 'me e matla e na le 150 hp. Mehlala e entsoeng ke baqapi ba Fiat Powertrain Technologies e na le moralo o thehiloeng ho enjene e 'ngoe e tsebahalang - 1.4 16V Fire. Leha ho le joalo, li ile tsa etsoa bocha ka lebaka la tlhokahalo ea ho kenya turbo.

Enjene ea jet ea 1.4 T e khetholloa ke taba ea hore e fana ka matla a lekaneng a lekaneng 'me ka nako e ts'oanang tšebeliso ea mafura a moruo. E boetse e na le mefuta e mengata ea li-rev le karabelo e ntle haholo ea gear shift. 

Lintlha tsa theknoloji ea Fiat unit

Enjene ea 1.4 T Jet ke DOHC inline-four enjene e nang le li-valve tse 4 ka silindara. Thepa ea yuniti e kenyelletsa ente ea elektronike, mafura a mangata, hammoho le turbocharging. Enjene e ile ea lokolloa ka 2007 'me ea fana ka likhetho tse 9 tsa matla: 105, 120, 135, 140 (Abarth 500C), 150, 155, 160, 180 le 200 hp. (Abarth 500 Assetto Corse). 

Enjene ea jete ea 1.4 t e na le lebanta la koloi le ente e sa tobang ea mafura. Re lokela ho hlokomela hore yuniti ha e na lintho tse ngata tse rarahaneng tsa sebopeho - ntle le turbocharger, e etsang hore ho be bonolo ho e hlokomela. 

Litšobotsi tsa moralo oa enjene ea jet lithane tse 1.4.

Tabeng ea 1.4 T Jet, cylinder block e entsoe ka tšepe e entsoeng ka tšepe 'me e na le matla a phahameng haholo a mechine. Karolo e ka tlase ea crankcase e entsoe ka alloy ea die-cast aluminium 'me ke karolo ea sebopeho se jereng mojaro hammoho le crankcase e kholo. 

E monya meroalo e hlahisoang ke crankshaft hape e theha setho se thata ka lebokose la gear ka letsoho la karabelo. E boetse e etsa mosebetsi oa ho lokisa ho beoa ha shaft ea axle e nepahetseng. Enjene ea 1.4 T e boetse e na le crankshaft ea tšepe e entsoeng ka tšepe e leka-lekaneng e robeli, crankshaft e thata ea induction le libere tse hlano.

Motsoako oa turbocharger e nang le intercooler le valve ea bypass - liphapang ho tsoa ho mofuta o akaretsang

Motsoako ona o entsoe ka ho khetheha bakeng sa liphetho tse peli tsa enjene ea 1.4 T-Jet. Leha ho le joalo, ho na le phapang pakeng tsa mefuta ena. Li bua ka eng? 

1. Bakeng sa enjene e seng matla haholo, jiometry ea lebili la turbine e netefatsa khatello e phahameng ho litorque tse phahameng ka ho fetisisa. Ka lebaka la sena, bokhoni bo feletseng ba yuniti bo ka sebelisoa. 
2. Ka lehlakoreng le leng, ka phetolelo e matla ka ho fetisisa, khatello e eketseha le ho feta ka lebaka la overboost, e leng ho eketsang torque ho fihlela ho 230 Nm le litšila tse koetsoeng. Ka lebaka lena, ts'ebetso ea lihlopha tsa lipapali e tsoteha le ho feta.

Ts'ebetso ea Unit - Mathata a Tloaelehileng

E 'ngoe ea likarolo tse fosahetseng ka ho fetisisa tsa enjene ea 1.4 T Jet ke turbocharger. Bothata bo atileng haholo ke nyeoe e robehileng. Sena se bonahatsoa ke mololi o ikhethang, mosi o tsoang ho tsoa le ho felloa ke matla butle-butle. Ho bohlokoa ho hlokomela hore sena se sebetsa haholo ho likarolo tsa turbine tsa IHI - tse nang le likarolo tsa Garrett, ha li na phoso.

Mathata a ho sebetsa hampe a boetse a kenyelletsa tahlehelo ea sepholisa. Ho ka fumanoa ho se sebetse hantle ha matheba a hlaha ka tlas'a koloi. Ho boetse ho na le mathata a amanang le ho lutla ha oli ea enjene - lebaka e ka ba ho se sebetse hantle ha bobbin kapa sensor. 

Joang ho sebetsana le mathata a enjene ea 1.4 T-Jet?

Ho sebetsana le bophelo bo bokhutšoanyane ba turbocharger, tharollo e ntle ke ho nkela liboutu tsa phepelo ea oli sebaka ka turbine ea oli. Sena se bakoa ke taba ea hore ka hare ho ntho ena ho na le filthara e nyane e fokotsang lubrication ea rotor haeba ho ka ba le tahlehelo ea boima. Leha ho le joalo, haeba ho na le mathata ka heatsink, ho molemo ho nkela karolo eohle sebaka. 

Leha ho na le mefokolo e itseng, enjene ea 1.4 T jet e ka hlahlojoa e le karolo e sebetsang hantle. Ha ho na khaello ea likarolo tse ling, e ka lumellana le ho kenya LPG mme e fana ka ts'ebetso e ntle - ka mohlala, tabeng ea Fiat Bravo, e tloha metsotsoana e 7 ho isa ho e 10 ho isa ho 100 km / h.

Ka nako e ts'oanang, e na le chelete e ngata - hoo e ka bang lilithara tse 7/9 ka 100 km. Tšebeletso ea kamehla, esita le lebanta la nako lik'hilomithara tse ling le tse ling tse 120. km, kapa flywheel e phaphametseng lik'hilomithara tse ling le tse ling tse likete tse 150-200, e lokela ho lekana ho nka monyetla oa yuniti ea jete ea 1,4-t nako e telele le ho rekota sebaka se phahameng.
