Injini yeJet 1.4 t - yini okufanele ukwazi?

Ngesikhathi bedala lesi sizukulwane, kwaFiat bathi injini engu-1.4 T Jet (njengamanye amayunithi alo mndeni) izohlanganisa isiko eliphezulu lomsebenzi nokushayela ngendlela eyongayo. Isixazululo sale nkinga kwaba inhlanganisela entsha ye-turbocharger kanye nokulungiswa kwengxube elawulwayo. Sethula ulwazi olubaluleke kakhulu mayelana ne-1.4T Jet evela kwa-Fiat!

Injini yeJet 1.4 t - ulwazi oluyisisekelo

Iyunithi itholakala ngezinguqulo ezimbili - ebuthakathaka inamandla angu-120 hp, futhi enamandla inama-150 hp. Amamodeli athuthukiswe abaklami be-Fiat Powertrain Technologies anomklamo osuselwe kwenye injini eyaziwayo - 1.4 16V Fire. Kodwa-ke, aklanywe kabusha ngenxa yesidingo sokufaka i-turbo.

Injini ye-jet engu-1.4 T ihluke ngokuthi inikeza amandla amakhulu ngokwanele futhi ngesikhathi esifanayo isetshenziswa ukonga kukaphethiloli. Iphinde ibe nohla olubanzi lwe-rev kanye nokuphendula okuhle kakhulu kwegiya. 

Idatha yezobuchwepheshe yeyunithi ye-Fiat

Injini engu-1.4 T Jet iyinjini ye-DOHC inline-four enamavalvu angu-4 isilinda. Imishini yalolu phiko ihlanganisa i-electronic, i-multi-point fuel injection, kanye ne-turbocharging. Injini ikhishwe ngo-2007 futhi yanikeza izinketho eziningi zamandla angu-9: 105, 120, 135, 140 (Abarth 500C), 150, 155, 160, 180 no-200 hp. (Abarth 500 Assetto Corse). 

Injini engu-1.4 t jet ine-belt drive kanye nomjovo kaphethiloli ongaqondile. Kumele kuqashelwe ukuthi iyunithi ayinazo izakhi eziningi zesakhiwo - ngaphandle kwe-turbocharger, eyenza kube lula ukuyigcina. 

Izici zokwakhiwa kwenjini ye-jet 1.4 amathani.

Endabeni ye-1.4 T Jet, i-cylinder block yenziwe ngensimbi ekhonjiwe futhi inamandla amakhulu kakhulu emishini. Ingxenye engezansi ye-crankcase yenziwe nge-die-cast aluminium alloy futhi iyingxenye yesakhiwo esithwala umthwalo kanye ne-crankcase eyinhloko. 

Imunca imithwalo ekhiqizwe yi-crankshaft iphinde yakhe ilungu eliqinile ngo-gearbox ngengalo yokusabela. Iphinde yenza umsebenzi wokulungisa ukuthwala kwe-axle shaft efanele. Injini engu-1.4 T iphinde ibe ne-crankshaft yensimbi eyakhiwe ngamabhalansi ayisishiyagalombili, i-induction hardened crankshaft nama-bearings amahlanu.

Inhlanganisela ye-turbocharger ene-intercooler kanye ne-bypass valve - umehluko ovela enguqulweni ehlanganisiwe

Le nhlanganisela yakhelwe ngokukhethekile imiphumela emibili yenjini engu-1.4 T-Jet. Nokho, kukhona umehluko phakathi kwalezi zinhlobonhlobo. Zimayelana nani? 

1. Enjinini enamandla kancane, ijiyomethri yesondo le-turbine iqinisekisa ukucindezela okukhulu kuma-torque aphezulu. Ngenxa yalokhu, amandla aphelele eyunithi angasetshenziswa. 
2. Ngakolunye uhlangothi, enguqulweni enamandla kakhulu, ingcindezi iyanda nakakhulu ngenxa ye-overboost, okwandisa i-torque ku-230 Nm ne-wastegate evaliwe. Ngenxa yalesi sizathu, ukusebenza kwamayunithi ezemidlalo kumangalisa nakakhulu.

Ukusebenza Kweyunithi - Izinkinga Ezijwayelekile

Enye yezingxenye ezinephutha kakhulu zenjini engu-1.4 T Jet yi-turbocharger. Inkinga evame kakhulu yicala eliqhekekile. Lokhu kuboniswa ngekhwelo eliwuphawu, intuthu ephuma eshishini kanye nokuncipha kwamandla kancane kancane. Kuyaqapheleka ukuthi lokhu kusebenza ikakhulukazi kumayunithi e-IHI turbine - afakwe izingxenye ze-Garrett, azinasici kangako.

Ukungasebenzi kahle okuyinkinga kuhlanganisa nokulahlekelwa into epholile. Ukungasebenzi kahle kungatholakala uma kuvela amabala ngaphansi kwemoto. Kukhona futhi ukungasebenzi kahle okuhambisana nokuvuza kwamafutha enjini - isizathu singase sibe ukungasebenzi kahle kwe-bobbin noma inzwa. 

Ungabhekana kanjani nezinkinga zenjini engu-1.4 T-Jet?

Ukubhekana nempilo emfishane ye-turbocharger, isisombululo esihle ukufaka amabhawodi okuphakela kawoyela esikhundleni se-oil turbine. Lokhu kungenxa yokuthi ngaphakathi kwalesi sici kukhona isihlungi esincane esinciphisa ukugcoba kwe-rotor uma kwenzeka ukulahlekelwa kokuqina. Kodwa-ke, uma kunezinkinga nge-heatsink, kungcono ukufaka yonke ingxenye. 

Naphezu kokushoda okuthile, injini ye-jet engu-1.4 T ingahlolwa njengeyunithi esebenza kahle. Akukho ukushoda kwezingxenye ezisele, ingahambisana nokufakwa kwe-LPG futhi inikeza ukusebenza okuhle - isibonelo, esimweni se-Fiat Bravo, isuka ku-7 kuya ku-10 imizuzwana kuya ku-100 km / h.

Ngesikhathi esifanayo, iyonga kakhulu - cishe amalitha angu-7/9 nge-100 km. Isevisi evamile, ngisho nebhande lesikhathi njalo ngemva kuka-120 km. I-km, noma i-flywheel elintantayo njalo nge-150-200 km eyizinkulungwane, kufanele yanele ukusebenzisa iyunithi ye-1,4-t jet isikhathi eside futhi irekhode imayela eliphezulu.
