I-Audi ibhiyozela iminyaka engama-25 ukususela ekufakweni kweenjini ze-TDI kuluhlu lwayo ngokuzisa i-Audi RS5 TDi Concept. Olunye ubhejo ngamakhonkco ophawu lokubonisa ukuba iibhloko zeDizili zinokuba nomlinganiswa wezemidlalo.
I-acronym TDI ibaluleke kakhulu kwi-Audi. Kangangeminyaka, itekhnoloji ye-TDI yeQela leVolkswagen ifumene kuphawu lwaseJamani umboniso ofanelekileyo wokwenziwa kwezinto ezintsha zobuchwepheshe. Sikhumbula, umzekelo, uloyiso lwe-Audi kuvavanyo lokunyamezela nge-R18 TDI; ingqikelelo ye-Audi R8 V12, eyayiyeyokuqala kwihlabathi (kwaye ukuza kuthi ga ngoku kuphela…) imoto yezemidlalo ebalaseleyo exhotyiswe ngenjini yedizili; okanye i-Audi Q7 V12 TDI, eyavela ixhotyiswe ngeyona injini yedizili inkulu kwaye inamandla ehlabathini.
Yonke le minyaka yendaleko ngokhuphiswano, ukuthengisa kunye nophuhliso lweenjini ze-TDI zibe nesiphumo semodeli entsha: i-Audi RS5 TDI Concept. Enye into ephambili kuphuhliso lweenjini zedizili abakwa-Audi bajonge ukuyinyusa phezulu.
Ngesi sizathu, i-Audi RS5 TDI Concept ifaka izinto ezintsha ezithathwe ngokuthe ngqo kwisebe lezemidlalo lophawu. Iinjongo zophawu kukwenza le RS5 TDI ibe yeyona Diesel yale mihla nenemidlalo yanamhlanje. Ugxininiso lucacile ekusetyenzisweni kwe-triple supercharging. Lilonke, kukho ii-turbos ezimbini kunye necompressor yevolumetric ukunika amandla injini ye-3.0 TDI esele siyayazi kwezinye iimodeli zohlobo (A6, A5, Q7, Q5).
Kwi-RS5 TDi Concept, ibhloko ye-3.0 TDI ngoku inika amandla amakhulu angama-385hp kunye ne-750Nm ye-torque ephezulu. Xa kuthelekiswa nomntakwabo wepetroli, inamandla angama-65hp, kodwa ingaphezulu kwe-320Nm yetorque ephezulu. Amanani ancomekayo ekuzakufuneka ajongane nawo i-8-speed R-Tronic gearbox kunye neQuattro all-wheel drive system.
Kodwa ngenxa yokuba kwimoto yezemidlalo ayingomandla kuphela obalulekileyo, i-Audi isebenzise ukutya okungqongqo kwibhloko ye-V6, yonga i-20kg kubunzima be-injini kunye nezinto zangaphakathi ezikhaphukhaphu, ezifana ne-crankshaft, ii-rods zokudibanisa kunye neepiston. Ukusebenza kwale RS5 TDi Concept ithembisa ukungadanisi nabani na. Ngokusuka ku-0 iye ku-100km/h nge-4s kuphela, nge-0.6s ngaphantsi kwe-RS5 yepetroli umzalwana wayo kunye nesantya esiphezulu ku-280km/h, imiphunga yinto engaswelekiyo le Audi.
U-Audi wagqiba ekubeni athathe indlela eyahlukileyo. Njengoko sele sikhankanyile, i-Audi RS5 TDi yimodeli yokuqala ye-brand yokuqalisa i-casing ene-supercharged, kunye nee-turbos ezimbini zenguqulo ye-3.0 ye-Bi-TDI, iqela lidityaniswe ne-compressor encinci ye-volumetric kunye nokusebenza kombane ngokupheleleyo, kunikwe amandla Inkqubo ye-48-volt kunye nebhetri / i-capacitor.
Umsebenzi wale compressor ulula: ukuvelisa uxinzelelo lwe-supercharge kwi-inertia ephantsi ye-inertia xa uxinzelelo lwegesi yokukhupha lungakwazi ukwenza njalo. Isiphumo? Eyona torque yale njini (750Nm) ifumaneka kwangoko 1250rpm. Ngaphandle kwe-lag kwimpendulo ye-throttle, zonke izixhobo zomlilo zifumaneka ngoko nangoko.
Ngamandla apheleleyo afikelela kwi-4200rpm, le RS5 TDi Concept, ithembisa ukuhlazisa umzalwana wayo wepetroli nokuba ikwindawo yokugcina amandla amakhulu, nokuba kukukhawulezisa kunye nokubuyiswa kwesantya ngaphandle kokuthandabuza, kukhatshwa yi-visceral torque discharge esetyenziswa kwinkqubo yeQuattro. Ukwenza nzima ngakumbi amatyala kumzalwana wayo wepetroli, i-Audi ibhengeza ukusetyenziswa okungaphantsi kwe-5L nge-100km.
Kwaye ucinga ntoni ngesi siphakamiso sivela kwa-Audi, ngaba uyakwazi ukunika amanani ale RS5 TDi Concept okanye umzalwana wayo wepetroli onebloko ye-V8, ngaba isenayo loo charm ekhethekileyo?
