Audi TFSI engine technology

The Audi’s relentless quest for automotive perfection has led to the continuous addition of cutting-edge technologies to their vehicles throughout its history. The engines from the Brand with The Rings are no exceptions, with the introduction of the TFSI technology in 2004 under the A3 Sportback’s hood.

TFSI, which is the acronym for Turbocharged Fuel Stratified injection, is the concept of associating direct fuel injection, dubbed by Audi as FSI, with a supercharger or a turbocharger. The direct injection enables the engine to create a stratified charge at lower rpms- i.e. create a richer air/fuel mixture near the spark plug without coming into contact with the wall of the cylinder. This greatly reduces the energy loss during the mixture combustion stage.

This allows for a 15% better fuel efficiency. Another advantage is the ability of the cylinder walls to be cooled down thanks to the gas evaporation when introduced directly in the cylinder chambers. The result is a higher compression ratio, which induces a higher power output. With the addition of a turbo or a supercharger, the power gain will be even better.

So come visit us at Audi Blainville, located between Boisbriand on the Montreal’s North Shore, and St-Jerome in the Laurentians, in order to learn more about the revolutionary TFSI technology!
