Injini ye-VR6 - ulwazi olubaluleke kakhulu mayelana neyunithi evela kwaVolkswagen

Injini ye-VR6 yasungulwa ngabakwaVolkswagen. Ukufakwa kokuqala kwethulwa ngo-1991. Njengelukuluku, singasho ukuthi i-VW nayo ihileleke ekukhiqizeni injini ye-VR5, umklamo wayo owawusekelwe kuyunithi ye-VR6. Ulwazi olwengeziwe mayelana nokufaka i-VR6 lungatholakala esihlokweni sethu.

Ulwazi oluyisisekelo mayelana neyunithi yeVolkswagen

Ekuqaleni, ungakwazi "ukuchaza" isifinyezo esithi VR6. Igama livela kusifinyezo esidalwe umkhiqizi waseJalimane. Incwadi ethi "V" ibhekisela ku-"V-motor", kanye nohlamvu "r" egameni elithi "Reihenmotor", elihunyushwa ngokuthi injini eqondile, emgqeni. 

Amamodeli e-VR6 asebenzise ikhanda elivamile kumabhange amabili amasilinda. Iyunithi futhi ifakwe camshafts ezimbili. Akhona womabili enguqulweni yenjini enamavalvu amabili namane isilinda. Ngakho-ke, ukuklanywa kweyunithi kwenziwa lula ekunakekeleni, okunciphisa izindleko zayo zokusebenza. Injini ye-VR6 isakhiqizwa. Amamodeli afakwe le njini afaka:

• Volkswagen Golf MK3, MK4 kanye MK5 Passat B3, B4, B6, B7 kanye NMS, Atlas, Talagon, Vento, Jetta Mk3 kanye MK4, Sharan, Transporter, Bora, New Beetle RSi, Phateon, Touareg, EOS, CC;
• I-Audi: A3 (8P), TT Mk 1 kanye ne-Mk2, Q7 (4L);
• Indawo: I-Alhambra noLeon;
• I-Porsche: I-Cayenne E1 ne-E2;
• I-Skoda: i-3T enhle kakhulu.

12 cylinder version

Amayunithi akhiqizwa ekuqaleni ayenama-valve amabili isilinda, enani lama-valve ayishumi nambili. Baphinde basebenzisa i-camshaft eyodwa kuma-valve okungenisa nawokukhipha kubhulokhi ngayinye. Kulokhu, azikho izingalo ze-rocker ezisetshenzisiwe noma.

Inguqulo yokuqala ye-VR6 ibe nokufuduka kwamamilimitha angu-90,3 ukuze kususwe inani eliphelele lamalitha angu-2,8. Inguqulo ye-ABV nayo yasungulwa, eyasakazwa emazweni athile aseYurophu futhi yayinomthamo wamalitha angu-2,9. Kuyafaneleka futhi ukusho ukuthi ngenxa yemigqa emibili yamapiston namasilinda anekhanda elivamile kanye ne-piston head gasket noma indawo yayo engaphezulu. ithambekele.

Kunguqulo engu-12-cylinder, i-engeli engu-V engu-15° ikhethiwe. Isilinganiso sokucindezela sasingu-10:1. I-crankshaft yayitholakala kuma-bearings ayisikhombisa amakhulu, futhi izintamo zahlanganiswa kusuka komunye nomunye ngo-22 °. Lokhu kwenza kube nokwenzeka ukushintsha ukuhlelwa kwamasilinda, kanye nokusebenzisa igebe lika-120 ° phakathi kwamasilinda alandelanayo. Isistimu yokulawula iyunithi ye-Bosch Motronic nayo yasetshenziswa.

24 cylinder version

Ngo-1999 kwethulwa uhlobo lwamavalvu angama-24. Ine-camshaft eyodwa elawula ama-valve okungena kuyo yomibili imigqa. Ngakolunye uhlangothi, enye ilawula ama-valve e-exhaust ayo yomibili imigqa. Lokhu kwenziwa kusetshenziswa izinsimbi ze-valve. Lesi sici sokuklama sifana ne-DOHC double overhead camshaft. Kulokhu kusetha, i-camshaft eyodwa ilawula ama-valve okungenisa kanti enye ilawula ama-valve okukhipha umoya. 

Ama-W-motor - ahlobana kanjani nemodeli ye-VR?

Isixazululo esithokozisayo esidalwe ukukhathazeka kweVolkswagen kwaba ukwakheka kwamayunithi anegama elithi W. Umklamo wawusekelwe ekuxhumekeni kwamayunithi amabili e-BP ku-crankshaft eyodwa - nge-engeli engu-72 °. Eyokuqala yalezi zinjini kwakuyi-W12. Yakhiqizwa ngo-2001. 

Owalandela, i-W16, yafakwa eBugatti Veyron ngo-2005. Iyunithi yakhelwe nge-engeli engu-90° phakathi kwamayunithi amabili e-VR8 futhi ifakwe ama-turbocharger amane.

Uyini umehluko phakathi kwenjini ye-V6 yendabuko kanye nenjini ye-VR6?

Umehluko wukuthi isebenzisa i-engeli encane engu-15° phakathi kwama-cylinder banks amabili. Lokhu kwenza injini ye-VR6 ibe banzi kune-V6. Ngenxa yalesi sizathu, iyunithi ye-VR kulula ukungena ekhomishini yenjini, eyayakhelwe ekuqaleni iyunithi yamasilinda amane. I-VR6 motor yakhelwe ukuthi ifakwe ngokuphambana ezimotweni ezidonsa ngamasondo angaphambili.
