What does TFSI mean?

turbo fuel stratified injection

Audi TFSI® stands for turbo fuel stratified injection.

TFSI stands for “TTurbo Fuel Stratified Injection”. It shares many similarities with other fuel injected petrol engines. The FSI designation describes the location of fuel injection. It is the only designation Audi and VW use to denote the petrol engine versions of their cars.

What does TFSI mean on an Audi?: TFSI stands for ‘TTurbocharged Fuel Stratified Injection’ and is used to signify that the engine is a turbocharged petrol unit. Around 15-20 years ago, Audi would also have sold ‘FSI’ engines, which didn’t have turbochargers. Since autumn 2017, Audi models will often come with a number in front of the TFSI or TDI badge.
What is a TFSI badge?: The TFSI badge is used on every petrol car Audi sells, while diesels are badged TDI. TFSI stands for ‘TTurbocharged Fuel Stratified Injection’ and is used to signify that the engine is a turbocharged petrol unit. Around 15-20 years ago, Audi would also have sold ‘FSI’ engines, which didn’t have turbochargers.
What is the FSI/TFSI principle?: FSI/TFSI principle. At Audi, FSI stands for gasoline direct injection, a technology in which fuel is injected directly into the combustion chambers, rather than into the intake manifold in the traditional manner. More favorable in terms of thermodynamics, this method improves the efficiency of the engine.
What is the difference between FSI and TSI?: The TSI engine superseded the turbo FSI with important technological and mechanical updates to address the downfalls of the FSI. It was first introduced in Volkswagen’s and Audi’s in 2008.5 and is still found in vehicles today. The engine base for these engines is mainly EA888 and it puts down anywhere from 170-310hp and 207-280lb-ft.
