Injini ye-Fiat 1.9 JTD - ulwazi olubaluleke kakhulu mayelana neyunithi nomndeni wakwaMultijet

Injini engu-1.9 JTD ingeyakwaMultijet. Leli yigama leqembu lezinjini zakwaFiat Chrysler Automobiles, okuhlanganisa namayunithi e-turbodiesel anomjovo oqondile wamafutha - Common Rail. Imodeli engu-1.9 litre ifakwe nasezimotweni i-Alfa Romeo, Lancia, Cadillac, Opel, Saab neSuzuki.

Ulwazi oluyisisekelo mayelana nenjini engu-1.9 JTD

Ekuqaleni, kufanelekile ukuzijwayeza ngolwazi oluyisisekelo mayelana neyunithi yokushayela. Injini engu-1.9 JTD inline four-cylinder yaqala ukusetshenziswa ngo-156 Alfa Romeo 1997. Injini efakwe kuyo inamandla angu-104 hp. futhi bekuyimoto yokuqala yabagibeli efakwe injini yedizili enomshini wokujova uphethiloli oqondile.

Eminyakeni embalwa kamuva kwethulwa ezinye izinhlobo ze-1.9 JTD. Bafakwe kwiFiat Punto kusukela ngo-1999. Injini yayine-turbocharger encane engaguquki yejometri, futhi amandla eyunithi ayengama-79 hp. Injini nayo yayisetshenziswa kwezinye izinhlobo zomkhiqizi wase-Italy - Brava, Bravo noMarea. Ezinye izinguqulo zeyunithi kukhathalogi yomkhiqizi zihlanganisa lawa makhono 84 hp, 100 hp, 104 hp, 110 hp. kanye 113hp 

Idatha yobuchwepheshe yeyunithi yamandla yakwa-Fiat

Le modeli yenjini isebenzise insimbi eyinsimbi enesisindo esingaba ngu-125 kg kanye nekhanda le-aluminium cylinder eline-camshaft efakwe ama-valve asebenza ngqo. Ukufuduka okuqondile kwakungu-1,919 cc, wazala 82 mm, unhlangothi 90,4 mm, isilinganiso sokucindezela 18,5.

Injini yesizukulwane sesibili yayinesistimu yezitimela evamile ethuthukisiwe futhi yayitholakala ngezilinganiso zamandla eziyisikhombisa ezahlukene. Zonke izinguqulo, ngaphandle kweyunithi ye-hp eyi-100, ifakwe i-turbocharger yejometri eguquguqukayo. Inguqulo engu-8-valve ihlanganisa i-100, 120 kanye ne-130 hp, kanti inguqulo ye-valve engu-16 ihlanganisa i-132, 136, 150 kanye ne-170 hp. Isisindo somgwaqo sasingamakhilogremu angu-125.

Ukumaka injini ezimotweni zezinye izinhlobo nokuthi ifakwe kuzona izimoto ziziphi

Injini engu-1.9 JTD ibingabhalwa ngendlela ehlukile. Bekuncike ezinqumweni zokumaketha zabakhiqizi abayisebenzisayo. U-Opel wasebenzisa isifinyezo esithi CDTi, u-Saab wasebenzisa igama elithi TiD nelithi TTiD. Injini yafakwa ezimotweni ezinjengalezi:

• I-Alfa Romeo: 145,146 147, 156, 159, XNUMX, GT;
• I-Fiat: Bravo, Brava, Croma II, Doblo, Grande Punto, Marea, Multipla, Punto, Sedici, Stilo, Strada;
• I-Cadillac: BTC;
• Umkhonto: Delta, Vesra, Musa;
• I-Opel: Astra N, Signum, Vectra S, Zafira B;
• Saab: 9-3, 9-5;
• I-Suzuki: SX4 ne-DR5.

Inguqulo ye-turbo enezigaba ezimbili - ubuchwepheshe be-twin-turbo

AbakwaFiat banqume ukuthi kusukela ngo-2007 bazosebenzisa uhlobo olusha lwe-turbocharged olunezigaba ezimbili. Ama-Twin turbos aqala ukusetshenziswa ezinguqulweni ze-180 hp. futhi 190hp ne-torque engu-400 Nm ku-2000 rpm. Eyokuqala yamayunithi ifakwe ezimotweni zemikhiqizo ehlukahlukene, kanti eyesibili kuphela ezimotweni ze-Fiat.

Ukusebenza kweyunithi yokushayela - yini okufanele uyibheke?

Izimoto ezihlome ngale yunithi yamandla zenze kahle. Umsebenzi wawumuhle kangangokuthi amamodeli amaningi asesimweni esihle kakhulu sobuchwepheshe naphezu kweminyaka edlule. 

Naphezu kokubuyekezwa okuhle, injini ye-1.9 JTD inezinkinga eziningi. Lokhu kufaka phakathi izinkinga nge-sunroof, i-exhaust manifold, i-valve ye-EGR, noma ukuhanjiswa okwenziwa ngesandla. Funda kabanzi mayelana namaphutha ajwayelekile. 

Ukungasebenzi kahle kwe-Flap 

Ezinjinini ze-diesel ezinama-valve angu-4 isilinda, ama-swirl flaps avame ukufakwa - kwelinye lamachweba amabili okungenisa e-cylinder ngayinye. Ama-dampers alahlekelwa ukuhamba kwawo ngenxa yokungcoliswa kwepayipi le-turbodiesel inlet. 

Lokhu kwenzeka ngemva kwesikhashana - i-throttle inamathela noma iphuka. Ngenxa yalokho, i-actuator ayikwazi ukusheshisa ibe ngaphezu kuka-2000 rpm, futhi ezimweni ezimbi kakhulu i-shutter ingaphuma futhi iwele kusilinda. Isixazululo senkinga ukufaka esisha esikhundleni se-multifold.

Inkinga nge-exhaust manifold, i-EGR ne-alternator

Ubuningi bokudla kungenzeka bukhubazekile ngenxa yamazinga okushisa aphezulu. Ngenxa yalokhu, uyayeka ukungena ekhanda le-cylinder. Imvamisa, lokhu kubonakaliswa yi-soot enqwabelana ngaphansi komqoqi, kanye nephunga elibonakalayo lokuphuma kwezimoto.

Izinkinga ze-EGR zibangelwa i-valve evalekile. Idrayivu ibe isingena kumodi yesimo esiphuthumayo. Isixazululo siwukushintsha ingxenye endala ufake entsha.

Ukwehluleka kwe-generator kwenzeka ngezikhathi ezithile. Kulesi simo, iyayeka ukushaja ngokujwayelekile. Isizathu esivame kakhulu yi-diode ku-voltage regulator. Kudingeka ukushintshwa.

Ukungasebenzi Kokudluliselwa Kwezandla

Ngesikhathi sokusebenza kwenjini engu-1.9 JTD, ukudluliswa kwezandla kuvame ukuhluleka. Naphezu kweqiniso lokuthi akuyona into eqondile injini, umsebenzi wayo ixhunywe drive unit. Ngokuvamile, ama-bearings wegiya lesihlanu nelesithupha ahluleka. Uphawu lokuthi uhlelo alusebenzi kahle umsindo nokuqhekeka. Ezinyathelweni ezilandelayo, ishafti yokudlulisela ingase ilahlekelwe ukuqondanisa futhi igiya lesi-5 nelesi-6 lizoyeka ukuphendula.

Ingabe injini engu-1,9 JTD ingabizwa ngokuthi ethembekile?

Lezi zithiyo zingakhungathekisa kakhulu, kodwa ngokwazi ukuthi zikhona, ungazivimbela. Kuyaphawuleka ukuthi, ngaphezu kwezinkinga ezingenhla, azikho izinkinga ezimbi kakhulu ngesikhathi sokusebenza kwenjini engu-1.9 JTD, engaholela, isibonelo, ekuguqulweni okukhulu kweyunithi yamandla. Ngenxa yalesi sizathu, i-motor evela kwa-Fiat - ngaphandle kokulimala okungathi sína, ingachazwa njengethembekile futhi izinzile.
