Self Study Programme 604 For internal use only Audi 3.0l V6 TDI Biturbo Engine Audi Service Training 3.0l V6 TDI biturbo engine Following the launch of the 2nd Gen 3.0l V6 TDI engine, Audi now The development goal was to build an engine that sets new stand introduces a biturbo version based on the 2nd Gen 3.0l V6 TDI ards for sporty diesel engines by ts dynamic torque and revving engine. ability. By adopting all effi ciency measures from the basic engine, The core of the unit is the compact two stage charging system e.g. thermal management system, friction reducing enhance installed in the inner V of the engine and over the gearbox bell ments, weight reduction and start stop system, the 3.0l V6 TDI housing. biturbo engine strikes a good balance between high performance The two in line chargers are subdivided into a high pressure and fuel effi ciency. Other premises for the development of the exhaust turbocharger and a low pressure exhaust turbocharger. engine were that it was to be produced on the assembly line of the The high pressure exhaust turbocharger has a Variable Turbine basic engine at the Györ engine plant, and that maximum use was Geometry with an electrical positioner. The low pressure exhaust to be made of common and synergetic parts shared with the turbocharger is regulated by a wastegate valve and designed for 2nd Gen V6 TDI engine. high air fl ow rates, with the result that the engine delivers high torque at low rpm combined with performance potential right up to the top end of the rev band. 604 003 Learning objectives of this Self Study Programme This Self Study Programme describes the design and function of Which aspects of the engine mechanicals have changed the 3.0l V6 TDI biturbo engine. After you have worked your way How is the cooling system confi gured in the cylinder head through this Self Study Programme, you will be able to answer the How is the biturbo system designed following q
