The new generation of the Audi 3.0 L V6 TDI engine

The new 3.0 I V6 TDI engine with four valves per cylinder, piezo injectors, common rail fuel injection system, turbocharging with variable turbine geometry (VTG), swirl action control and dual coolant circuit with intelligent thermal management and integrated exhaust gas recirculation (EGR) cooling develops — depending on the intended application — between 150 kW and 184 kW and has a maximum torque of between 400 Nm and 550 Nm. It complies with Euro 5 exhaust emission limits and has very low CO2 emissions. In the following thermodynamics, application and exhaust emission control of the new engine are described. The first part of the article in MTZ 10 already depicted the design and the mechanics of the new engine.
