Unyaka ka-2008 wawungeke uqale, emhlabeni wezimoto, ngokuqhuma okukhulu. Abakwa-Audi bazoletha embukisweni wezimoto iDetroit Motor Show - ohlale njalo ezinsukwini zokuqala zonyaka - i-prototype engu-R8 ezozamazamisa izisekelo zazo zonke izinkolelo ngemidlalo emsulwa nemidlalo emikhulu. I-Audi R8 eveziwe ifakwe ibhulokhi enkulu eyi-V12… Udizili!
Ungawacabanga amagagasi ethusayo nokumangala? Imoto yezemidlalo ye-Diesel super?!
Amazwi aphikisayo ayegomela ngokuthi i-Supercar ye-Diesel ingumbono ongenangqondo. Ukwenza ukwethulwa kwale modeli, bekungeyona neze...
Lokhu bekungu-2008 hhayi u-2018 (NDR: ngosuku lokushicilelwa kwasekuqaleni kwalesi sihloko).
Injini kadizili yayingumngane omkhulu wemoto. Izinjini zikadizili bezilokhu zidayiswa ngokwandayo, okudale ukuthi kudayiswe cishe uhhafu emakethe yaseYurophu, kanti i-Audi ikakhulukazi isivele yanqoba kabili ku-24 Hours of Le Mans nge-Audi R10, eyi-prototype Diesel - into engakaze ibonwe. Futhi akugcinanga lapho, ingqikithi yokunqoba kweLe Mans eyisishiyagalombili ngama-prototype asebenza ngodizili.
Yilokhu kuphusha, emakethe nasemqhudelwaneni, okwavumela uDiesel ukuba abonakale njengezinjini ezonga uphethiloli nje - kwa-Audi, Le Mans prototypes kwakuyimibukiso yezobuchwepheshe eyayibonakala ezimotweni zabo zomgwaqo. Ukuziphendukela kwemvelo okuphawulekayo, okudlulele kuzo zonke izinhlobo zezimoto.
Naphezu “kwedemoni” ababhekene nakho namuhla, kubalulekile ukungakhohlwa ukubaluleka nencazelo izinjini zikaDiesel ake zaba nazo.
amahemuhemu
Ngo-2006 abakwa-Audi baba nesibindi sokwethula imoto engemuva enenjini ephakathi, i-R8 - imoto enkulu encane, njengoba abanye emaphephandabeni beyibiza kanjalo. Ukubukeka okuyingqayizivele, ibhalansi eguquguqukayo kanye nobuhle bemoto yayo engu-4.2-litre V8 — 420 hp enamandla angu-7800 rpm — kuyenze ngokushesha yaba enye yezimoto ezifunwa kakhulu i-Audi nezemidlalo okwamanje.
Ithuthukiswe ngamasokisi nge-Lamborghini Gallardo, kwakuyisiphakamiso esingakaze sibonwe kumkhiqizo wamasongo. Imele isiqongo somkhiqizo emazingeni amaningana, okuqubule amahlebezi ngokushesha: ngokunqoba kweLe Mans, ngabe i-Audi izozuza kanjani empumelelweni yomncintiswano ngokwethula i-supercar Diesel?
I-Audi R8 V12 TDI
Lokho bekungeke kwenzeke, kwasho abaningi. Injini ye-diesel enika amandla i-supercar? Bekungawenzi umqondo.
Ukushaqeka
Futhi sabuyela eDetroit ekuqaleni kuka-2008. Phakathi kwesikrini somusi (hhayi esivela enjini) kwafika I-Audi R8 V12 TDI Concept — kamuva yaqanjwa kabusha ngokuthi i-R8 Le Mans Concept.
Ngokusobala bekungu-R8, naphezu kobhampa abahlukene, ukushaywa kwezinhlangothi ezivuthayo, kanye nokungenela kwe-NACA (ethola igama layo ngokwakhiwa yiKomidi Likazwelonke Lokweluleka le-Aeronautics) phezulu ngokupholisa injini. Futhi leli gama lalingakhohlisi, i-Audi yethula iDizili yezemidlalo ephezulu.
Esikhundleni se-V8 Otto ngemuva kwabagibeli bekukhona 'inunu' i-V12 Diesel, enkulukazi kuze kube manje ebekwe emotweni elula: Amasilinda angu-12 ku-V, njengasezindaweni ezinhle kakhulu zesupersports, amandla angu-6.0 amalitha, ama-turbos amabili, ama-500 hp kanye nokuduma kwe-1000 Nm… ngo-1750 rpm (!). Futhi, cabanga, kuhlanganiswe nokudluliswa kwezandla.
Ngezinombolo ezinjengalezi, akumangazi ukuthi umoya omkhudlwana uthatha injini.
Ngokuphambene namahemuhemu, le njini ibingaphumanga ku-5.5 l V12 yomncintiswano u-R10, kodwa ihlanganyele nayo okuningi ngezakhiwo nobuchwepheshe obusetshenziswa.
Ngokwezinombolo zalolu hlobo, i-Audi R8 V12 TDI, edonsa ngamasondo amane, izokwazi ukugijima ifinyelele ku-100 km/h ngama-4.2s futhi ifinyelele ku-300 km/h—hhayi kubi…
ubunkimbinkimbi bezobuchwepheshe
I-Audi R8 V12 TDI Concept izophinde ibonakale ezinyangeni ezimbalwa kamuva embukisweni wezimoto i-Geneva Motor Show, ithatha indawo yombala ompunga yasekuqaleni ifake obomvu obugqamile. Okubaluleke nakakhulu, kwakuyi-prototype esebenzayo, eduze nokukhiqizwa - ezinye izintatheli zazikwazi ngisho nokuwushayela.
Ikhawunta ye-rev "enomugqa obomvu" ngo-4500 rpm… emotweni yemidlalo esezingeni eliphezulu!
Kodwa kwasheshe kwacaca ukuthi lokhu "ukuhlolwa kwelabhorethri" kwakuzokwazi kancane kancane futhi icala kwakuyinjini, noma kunalokho ubukhulu bayo. Ibhulokhi ye-V12 yayiyinde kune-V8, ngakho "yangena" ingxenye yekhabini ukuze ilingane.
Futhi akuzange kushiye isikhala sokufaka noma yiziphi izinto ezisetshenziswayo ze-Audi R8 - ngaphezu kwalokho, akekho kubo owayezimisele ukumelana ne-torque engu-1000 Nm esuka kubhulokhi enkulu.
Kudingeke ukuthi basebenzise i-compact Audi A4 transmission ukuze ikwazi ukugibela i-Audi R8 V12 TDI prototype, kodwa njengamanye ama-transmission, ayikwazanga ukuphatha itorque engu-V12, ngakho itorque ibinomkhawulo wokwenziwa.
ukuqala kokuphela
Njengoba ungase uqonde, umsebenzi wokufaka injini ye-V12 emzimbeni obungahlosiwe ukuyithola, ubonakale uyinkimbinkimbi futhi ubiza. Isinyathelo sokugcina ekukhiqizeni sizodinga ukulungisa kabusha ingxenye engemuva ye-R8 nokudala ugesi kusukela ekuqaleni ongeke wanele kuphela isikhala esilinganiselwe esikhona, kodwa futhi usekele i-1000 Nm.
Ama-akhawunti awazange ahlanganise—izibalo zokukhiqiza ezilindelwe zalokhu 'kuhlubuka' okunamasondo akuzange kuthethelele ukutshalwa kwezimali okudingekayo. Ngaphezu kwalokho, ezinye izimakethe ezibalulekile empumelelweni yayo, njenge-US, lapho i-Audi ithengise ingxenye yesithathu yawo wonke ama-R8, azizange zikwazi nhlobo ukwamukela izinjini zikadizili, ingasaphathwa eyemoto enkulu enalolo hlobo lwenjini.
Ngemuva kokucula eDetroit, yathola umbala negama elisha leGeneva - Audi R8 TDI Le Mans Concept.
I-Audi iqede iphrojekthi ngokungaguquki - i-supercar kadizili izobe iphelele endaweni yamathuba. Kwaba isiphetho super sports car Diesel, kodwa hhayi ekupheleni block enamandla.
Bekungesona isiphetho se-V12 TDI enkulu… futhi ngiyabonga
Inqatshwe ku-R8, injini ye-V12 TDI ithole isikhala emzimbeni ofaneleka kakhulu. I-Audi Q7 V12 TDI, nayo eqale ukumakethwa ngo-2008, isiphenduke imoto yokukhiqiza enalesi sitimela esisebenza ngogesi.
Kuseyiyona yodwa imoto elula esike yaba ne-V12 Diesel ngaphansi kwesivalo — enamandla afanayo nezibalo ze-torque njenge-Audi R8 V12 TDI — kanye ne-ZF edonsa ngamagiya ayisithupha azishintshayo, iqiniswe ukuqinisekisa ukuqina kwayo emsebenzini wokubhekana ne-1000 Nm.
Ngemuva kwayo yonke le minyaka isaqhubeka nokuhlaba umxhwele...
