1.9 Injini ye-CDTi/JTD evela kwa-Opel - thola okwengeziwe!

Injini kadizili yakwaFiat yathakaselwa kakhulu onjiniyela bazo zonke izinkinga ezinkulu zezimoto. Ngakho-ke, injini ye-1.9 CDTi ayifakiwe kuphela ezimotweni zomkhiqizi wase-Italy, kodwa nakwamanye ama-brand. Funda kabanzi ngakho esihlokweni sethu! 

Ulwazi oluyisisekelo mayelana neyunithi yamandla

Injini yokuqala engu-1.9 CDTi yafakwa ku-156 Alfa Romeo 1997. Le njini yakha i-104 hp. (77 kW), okwenza le modeli yemoto ibe yimoto yokuqala yabagibeli emhlabeni ngalobu buchwepheshe. Kufanelekile ukuhlala kafushane kubuchwepheshe be-Common Rail futhi uchaze umsebenzi wabo - kungani kube yimpumelelo enkulu emlandweni wokukhiqiza ukushayela. Njengomthetho, ama-injection kaphethiloli alawulwa ngomshini asetshenziswa ezinjinini ezijwayelekile zikadizili. Ngenxa ye-Common Rail, lezi zingxenye sezilawulwa iyunithi yokulawula injini ye-elekthronikhi.

Ngenxa yalokhu, kwakungenzeka ukudala iyunithi yamandla edizili esebenza buthule, ingabhemi, ikhiqize amandla afanele futhi ingadli uphethiloli omningi. Izixazululo zakwaFiat maduzane zamukelwa ngabanye abakhiqizi, okuhlanganisa ne-Opel, bashintsha igama lenjini lokumaketha lisuka ku-1.9 JTD laya ku-1,9 CDTi.

Izizukulwane zeyunithi ye-1.9 CDTi - i-JTD ne-JTDM

Lena yifour-cylinder, in-line 1.9-litre esebenzisa iCommon Rail system. Imodeli yesizukulwane sokuqala yadalwa njengokubambisana phakathi kweFiat, Magneti, Marella kanye neBosch. Idrayivu ithathe indawo ye-1.9 TD eyayishaywe kabi futhi yayitholakala ku-80, 85, 100, 105, 110 kanye no-115 hp. Endabeni yezinketho ezintathu zokugcina, i-Fiat yanquma ukufaka i-turbine ye-geometry eguquguqukayo esikhundleni se-fixed, njengoba kwenzeka kwezinye izimo.

Isizukulwane senjini engu-1.9 CDTi singahlukaniswa izizukulwane ezimbili. Eyokuqala yakhiqizwa kusukela ngo-1997 kuya ku-2002 futhi yayingamayunithi anohlelo lwe-Common Rail I, kanti eyesibili, esatshalaliswa kusukela ekupheleni kuka-2002, yayifakwe uhlelo oluthuthukisiwe lomjovo we-Common Rail.

Yini eyenza i-Multijet yesizukulwane sesi-XNUMX yehluke?

Okusha kwakuyingcindezi ephezulu yokujova uphethiloli, kanye nezinhlobo ezinamandla kakhudlwana ezino-140, 170 no-150 hp. ifakwe ama-valve amane nama-camshaft amabili, kanye ne-geometry turbine eguquguqukayo. Izinguqulo ezibuthakathaka ze-105, 130 kanye ne-120 km zisebenzisa ama-valve angu-8. Inguqulo ye-twin-turbocharged ene-180 ne-190 hp nayo yavela emakethe. kanye ne-torque engu-400 Nm ku-2000 rpm.

Kuphinde kwasetshenziswa ama-servo valves amasha, okuthuthukise kakhulu ukunemba kokulawula inani likaphethiloli elijovwe egunjini elivuthayo imijovo eyisishiyagalombili elandelanayo. Kuphinde kwanqunywa ukuthi kwengezwe imodi yomjovo we-Injection Rate Shaping, enikeze ukulawula okungcono ukusha, ukunciphisa umsindo okhiqizwa ngesikhathi sokusebenza kweyunithi, futhi kuthinte nokusebenza kahle kwenjini iyonke.

Iziphi izinhlobo zezimoto injini engu-1.9 CDTi efakwe kuzo?

Iyunithi yamandla ifakwe ezimotweni ezifana ne-Opel Astra, Opel Vectra, Opel Vectra C kanye neZafira. Ama-motor nawo asetshenziswa ezimotweni zomkhiqizi waseSweden i-Saab 9-3, 9-5 Tid ne-TTiD, kanye neCadillac. Injini engu-1.9 CDTi iphinde yasetshenziswa kwiSuzuki SX4, abakwaFiat baphinde basebenza kuyo.

Ukusebenza kweDrayivu - yini okufanele uyilungiselele?

Kunezinkinga ezimbalwa ngenjini engu-1.9 CDTi abasebenzisi abaningi ababhekana nazo. Lokhu kufaka phakathi ukuhluleka kokukhipha amandla okuningana, i-valve ye-EGR noma i-alternator, kanye ne-gearbox ye-M32 enephutha. 

Naphezu kwalezi zinkinga, injini ibhekwa njengeyunithi ethuthuke kakhulu. Kuyaphawulwa ukuthi izinkinga ngezingxenye zezimoto azivamile kakhulu. Ngakho-ke, ekusebenzeni okungenazinkinga kweyunithi, umsebenzi wesevisi ojwayelekile kanye nokushintshwa okujwayelekile kwamafutha edizili kwanele.

Ingabe umkhiqizo we-Opel ne-Fiat uyisinqumo esihle?

Ukukhetha injini engu-1.9 CDTi, ungaqiniseka ngokwethembeka kwayo. Iyunithi yokushayela isebenza ngokuzinzile futhi, njengomthetho, akukho ukwehluleka okungaholela ekulungisweni okukhulu kweyunithi. Ngenxa yalesi sizathu, le injini kungenzeka ibe yisinqumo esihle.
