2.0 T with FSI technology is “Engine of the Year”

Audi’s pioneering work in the domain of petrol direction injection technology is receiving worldwide recognition. A specialist jury made up of 56 respected journalists from 26 countries voted the 2.0 TFSI winner of the “Engine of the Year” award for the second year in a row.

Audi is the first manufacturer in the world to have combined petrol direct injection with turbocharging in the sphere of volume production. The 2.0 TFSI embarked on its success story in the Audi A3 Sportback. It is now also on offer in the Audi A4 and A6. It is available in three output versions ranging from 170 bhp to 220 bhp.

The jurors were impressed by the engine’s pulling power and high level of everyday suitability. The exceptionally broad torque plateau on the one hand permits a fuel-efficient driving style, and on the other hand means that only light accelerator action is needed to produce assertive thrust and a spontaneous unleashing of power.

With FSI technology, fuel is injected directly into the combustion chamber. The injector, located on the admission side in the cylinder head, is served by a high-pressure pump driven by the camshaft and a pressure reservoir shared by all cylinders – the common rail system.

The turbo engine achieves a compression ratio of 10.5:1, a figure that is otherwise typically achieved only by naturally aspirated engines. This, coupled with the advantages of petrol direct injection, plays a crucial role in boosting thermodynamic efficiency compared with both manifold injection engines and conventional turbo engines.
