Audi - nuovo V6 TDI Clean Diesel 3.0 litri Euro 6 e DSG7 longitudinale per trazioni anteriori
nella discussione ha aggiunto Beckervdo in Innovazione Meccanica
The new V6 diesel features a number of advanced technologies. The piston rings and pins have been optimized for minimal friction. The crankcase and the newly designed cylinder heads have separate coolant loops. The updated, innovative thermal management system improves efficiency even further. The turbocharger and the fully variable‑load oil pump have also been updated.Also, for the first time, a NOx storage catalytic converter has been combined with a diesel particulate filter and SCR injection in a single assembly. The exhaust gas after‑treatment integrated into the engine package satisfies the most stringent of emissions legislation, including the Euro 6 standard. It also reduces CO2 emissions by an average of 15 grams (24.1 g/mi). The Audi lineup offers a broad choice of diesel engines with four, six and eight cylinders. It begins with the 1.6 TDI, includes the 2.0 TDI and 3.0 TDI, and tops out with the 4.2 TDI producing 283 kW (385 hp) and 850 N·m (626.9 lb‑ft) of torque in the Audi A8 [7.4 l/100 km (31.8 mpg US), 194 g CO2 per km (312.2 g/mi)]. All of these engines combine ample power with efficiency, particularly in the 13 ultra models currently available. The Audi A4 1.6 TDI ultra, for example, consumes on average just 3.2 liters of fuel per 100 kilometers (73.5 mpg US) [85 grams CO2per km (136.8 g/mi)]. These same figures for the A4 2.0 TDI ultra are 4.0 liters per 100 kilometers (58.8 mpg) [104 grams CO2 per km (167.4 g/mi)] and for the A6 2.0 TDI ultra with S tronic 4.4 liters per 100 kilometers (53.5 mpg) [114 grams CO2 per km (183.5 g/mi)]. Audi honored a small tradition with its presentation of the new 3.0 TDI engine at the Symposium; the company presented its five‑cylinder TFSI engine here in 2009 and in 2010 the (at that time) new 3.0 TDI. The premieres of the 3.0 TDI biturbo and the new 1.8 TFSI followed in 2011. Audi presented the 4.0 TFSI in 2012, and the company first presented the V6 TDI for the Audi R18 e‑tron quattro race car to the public at the 2013 Vienna Motor Symposium. Besides the new 3.0 TDI, Audi is also presenting another innovation in Vienna: a new seven-speed dual‑clutch transmission for models with longitudinal engines and front‑wheel drive. The latest-generation S tronic is extremely sporty, yet very comfortable. The newly developed dual-clutch transmission reduces CO2 emissions by as much as 10 grams per kilometer (16.1 g/mi). Via GreenCarCongress Dopo il V6 BiTDI ed il V6 TDI Electric BiTurbo...arriva l'evoluzione per il 3.0 litri monoturbo, con norma Euro6 e per la prima volta con convertitore catalitico, DPF e filtro SCR tutto in un unico comparto (sai che gioia). Evoluzione che si porta dietro - finalmente - l'abbandono della trasmissione Multitronic per l'utilizzo di un nuovo 7 marce per motori longitudinali e trazione anteriore.
