2014 Audi new 3.0L V6 TDI engine details exposed

　　[Quanzhou Yisheng Machinery Co., Ltd. Technical Channel] At the two-day Vienna Automotive Symposium from May 8th to 9th this year, Audi exhibited an upgraded version of its 3.0 TDI V6 engine, compared to the current one in the United States With the 3.0 TDI V6 engine in service, this upgraded version of the power engine has risen to a level in terms of fuel consumption and power performance.

　　 Let’s first take a look at the power and fuel performance of the 3.0 TDI V6 engine currently in service in the United States. The 3.0 TDI V6 engine currently mounted on the Audi A6 is divided into two power versions. The maximum output torque of the low-power engine is 325 N·m, the maximum output torque of the high-power engine is 580 N·m, and the North American version of the Audi A6 has a combined fuel consumption of 8.2 per 100 kilometers. L.

　　 This upgraded version of the diesel engine has also been tuned to two power outputs: 215 horsepower and 268 horsepower. The maximum output torque of the high-power version of the engine that Audi exhibited at this Vienna Automotive Symposium is close to 600 N·m, and the fuel efficiency of the low-power version of the engine is improved by 13% compared to the previous improvement. In other words, the improved 3.0 V6 TDI engine is either more powerful than the current model, or has better fuel efficiency than the current model. Consumers can choose according to their preferences.

　　 In order to obtain more powerful power and more economical fuel consumption, let’s take a look at the improved version of the 3.0 TDI V6 engine compared to the current V6 engine. What are the improvements: First, improve the main Occurs in pistons, crankcases, cylinder heads, catalytic converters, oil filters, and direct fuel injection systems.

The piston ring and piston pin on the piston are treated with '0' friction smoothing; the cylinder head has also been redesigned; the crankcase and cylinder head have adopted two independent sets Cooling system: The catalytic converter has the largest change, and the transfer rate of nitrogen oxides reaches the highest; the direct injection system is changed from a distributed design to an integrated design. These improvements make the emissions of the upgraded 3.0 TDI V6 engine meet the Euro 6 standard.

　　In this Vienna seminar, Audi not only exhibited an upgraded version of the 3.0 TDI V6 engine, but also exhibited a new seven-speed dual-clutch gearbox. The gearbox is specially matched with longitudinal front-wheel drive models. As for which model will be used first in the future, the official has not yet given a clear answer.

　　 Audi diesel engine family currently includes four-cylinder, six-cylinder and eight-cylinder products for consumers to choose from. The displacements are 1.6TDI, 2..0TDI, 3.0TDI, and the highest 4.2TDI. Among them, the 4.2TDI displacement engine can produce up to 385 horsepower and up to 850N·m of torque. It is mounted on the Audi A8. The fuel consumption of the Audi A8 is only 7.4L per 100 kilometers. Currently, Audi has 13 engines in service in North America.

　　The Vienna Automotive Seminar is an important product appearance occasion for Audi. For example, Audi unveiled a total of 5 3.0 TDI engines at the seminar in 2009 and 2010. In 2011, the 3.0TDI engine and 1.8TFSI engine were unveiled. The 4.0TFSI engine was unveiled in 2012. The V6 engine on the Audi R18 racing car that represented Audi in the F1 car was announced at the Vienna Motor Symposium in 2013.
