Audi A6L Technology Highlights Introduction Video
1.？ Power assembly
This time, Audi A6L (parameter | picture) introduced the well-known 2.0T EA888 Gen3B four-cylinder turbocharged engine, and Xiaoxing especially wanted to mention the new Audi.
A6 (parameter | picture) L uses this 3.0L V6 engine. Friends who are familiar with Audi know that the 3.0L V6 supercharged engine was widely used on Audi models before. So what is the origin of this new generation 3.0TFSI turbocharged engine code-named EA8 (parameter | picture) 39? Let Xiaoxing analyze it carefully.
↑ The new EA839 3.0TFSI V6 engine adopts single turbine and double scroll layout (from Audi).
The new EA839 3.0TFSI V6 engine adopts the layout of single turbine and double scroll tubes, which was jointly developed by Porsche and Audi. It can generate a maximum torque of 250 kW (340 HP) and 500 Nm. Compared with the previous generation 3.0L V6 supercharged engine, the power is improved and the weight is greatly reduced. From the original 189kg to 172kg. The secret of its performance improvement comes from the following features:
1)? B cycle control (flexible switching between Otto cycle and Miller cycle)
2)? Single turbine and double scroll layout (improving the dynamic response of turbine)
3)? Overhead exhaust system (more integrated engine layout)
4)? Central high-pressure fuel injection system (250 bar high-pressure injection optimizes combustion performance)
5)? Intelligent thermal management system (strategic control of engine preheating and cooling process)
