Audi to applaud 10 years of TDI during Le Mans

Posted on 15. Jun, 2016 by in Audi Canada

In 2010, Audi achieved a subsequent vital step with a R15 TDI. Its V10 TDI engine transposed a prior twelve-cylinder unit. It was 100 millimeters shorter, 10 percent lighter and powered a open-cockpit sports vehicle to a new tip performance. Timo Bernhard/Romain Dumas/Mike Rockenfeller (D/F/D) lonesome 5,410.713 kilometers in 397 laps during Le Mans. With that, they pennyless a 39-year-old record from an epoch when no chicanes slowed a gait on a Hunaudières straight. In a arrangement flight, a Audi R15 TDI clinched a one-two-three win. For a initial time a 5.5-liter V10 TDI used dual turbochargers with non-static turbine geometry (VTG) that softened a engine’s responsiveness. 

The Audi R18 TDI ushered in a new epoch in 2011. An innovative, compress and really fit V6 TDI engine now powered a closed-cockpit sports car. To significantly revoke expenditure and boost prolongation aptitude by downsizing, a engine’s banishment decreased by 1.8 to 3.7 liters. The cylinder banks with a 120-degree angle enclosed a empty side – in other difference a empty manifolds were inside a V pattern as well. A singular double-flow turbocharger was fed by a empty of both banks and a compressor was of a double-flow pattern as good and destined a uninformed atmosphere by dual intercoolers into a intake manifolds on a outside.

The potency gains voiced in compress figures: In a diesel epoch given 2006 a hole of a atmosphere restrictor decreased by 34 percent, assign vigour was reduced by 4.7 percent and cubic ability by scarcely 33 percent. Absolute appetite outlay on a other palm forsaken from some-more than 478 kW (650 hp) to about 360 kW (490 hp), in other difference by usually 24 percent. As a result, outlay per liter increasing from 87 kW (118 hp) in 2006 to 107 kW (146 hp) in 2011, equating to a and of scarcely 24 percent. The aloft injection pressures of a racing injectors lead to even some-more fit combustion. Now handling during 3,000 bar a racing engine was a prototype of a rising pressures creation their approach into a automobile.

Marcel Fässler/André Lotterer/Benoît Tréluyer (CH/D/F) won in 2011 with a R18 TDI and a year after with a R18 e-tron quattro that used a hybrid powertrain for a initial time. In 2013, Loïc Duval/Tom Kristensen/Allan McNish (F/DK/GB) were winning during Le Mans with a serve grown chronicle of a R18 e-tron quattro. Following Fässler/Lotterer/Tréluyer in 2012, they were a subsequent pretension winners in a 2013 FIA World Endurance Championship (WEC). In 2014, potency regulations came into outcome that noted a radical change in racing. Instead of tying outlay by factors such as atmosphere limitation or cubic ability a stipulations practical quite to energy. Audi lengthened a V6 TDI engine that had to make do with about 22 percent reduction fuel than a prototype to 4 liters of displacement. The contingent of Fässler/Lotterer/Tréluyer achieved a third feat – imprinting a eighth for a TDI engine from Audi during Le Mans.

For a 2016 season, a regulations have serve reduced appetite consumption. Audi has grown a V6 TDI engine to a new turn once more. “We’re now regulating a engine judgment for a sixth uninterrupted year. This shows how good a simple thought still is,” says Ulrich Baretzky, Head of Engine Development during Audi Sport. “Due to potency increases, we’re compensating for a reduce volume of fuel to some extent.” 

The stream V6 TDI engine consumes 32.4 percent reduction fuel than a initial era from 2011. The swell done in comparison to 2006 is even some-more substantial. Today, Audi’s LMP1 competition vehicle with a stream powertrain uses 46.4 percent reduction fuel during Le Mans than it did 10 years earlier. In annoy of this, it achieves path times that are 10 to 15 seconds improved than those a decade ago. All this is probable interjection to a particular strides that have been made, quite in a areas of aerodynamics, lightweight pattern and powertrain.
