China Metalworking Online Reporter recently learned from FAW-Volkswagen Audi that the 09 A6L sedan will increase the 3.0TFSI version and discontinue the old 3.2-liter engine. The new engine has a displacement of 2,995 cc, which is in line with the consumption tax of large-displacement cars that will be implemented in September. It is within the scope of no adjustment, so it is good news for potential consumers of Audi.
Although the displacement is less than 3.0 liters, the power is stronger than the high displacement engine.
Although the engine of the domestic A6L is smaller than the original 3.2-liter engine, it surpasses the engine with larger displacement in terms of power and torque performance. And is "TFSI" like Volkswagen's "TSI" engine, which is "turbocharged + direct fuel injection"? Let's take a look at the difference between this engine and where it is.
3.0TFSI≠turbocharged + direct fuel injection
The same as the Audi engine we used to know, this new engine also uses these characters "T" and "FSI". After opening the hood of the Audi A6L2.0T sedan, you will find the words "TURBO" and "FSI" on the engine; Volkswagen Magotan's 2.0TSI engine also regards "TSI" as the focus of publicity, and the aforementioned " T" does represent "turbocharging" technology. Therefore, Audi's new 3.0TFSI engine puts these four letters together, making it easy to associate with "3.0 turbocharged + direct fuel injection."
In fact, the "T" in this 3.0TFSI engine does not refer to Turbo - turbocharging technology. Through the above cross-sectional view you have probably discovered the supercharger driven by the drive belt. This is also the first time that Audi has given the concept of “T†to “mechanical pressurizationâ€, while the Mercedes-Benz, which also has supercharged technology, uses the first letter “K†of the German supercharger, such as Mercedes-Benz E200K and C200K. .
Compared to turbochargers, supercharged engines have some inherent advantages, such as faster work response, which is especially important when the vehicle is in its infancy. According to the official data, the 3.0TFSI engine can have a torque of 420 Nm from 2500 rpm, and this torque can last up to 4850 rpm, which is more than the current A6L3.2 engine. The height is 90 Nm; at the same time, the maximum power of 213 kW is 25 kW higher than the 3.2-liter engine.
In the history of Audi cars, the Auto Union, the predecessor of Audi in the 1930s, used supercharging technology. But in the past 30 years, Audi's main energy has been on turbo technology, so the birth of this supercharged 3.0 engine is also seen as the "recovery" of Audi's supercharged technology.
