Some German vehicles are known for their Turbo Fuel Stratified Injection engine (TFSI). We discussed this in detail in a previous post, which you can read here. Audi also has a variant of this engine, available for the next-generation A4, released in 2015. Learn about the Audi TFSI engine and its unique combustion delivery method.
The Inner Workings of TFSI Engines
German automobiles require upkeep and tune-ups from a VW & Audi service. The TFSI engine is no different. The Audi A4 produces up to 190 hp and 236 lb-ft of torque. This is due to a new combustion deployment that works in the same style as the Miller cycle.
The Miller cycle uses a supercharger and an intake valve that stays open during the compression stroke. This leads to about a 15% boost in engine performance.
The difference, though, is in the crank angle that has been lowered from 200 to 140 degrees. A bigger boost pressure on the inlet side has also been incorporated. This minimizes the engine’s intake time without lowering its cylinder charge. With a better combustion cycle, the A4 provides a drastically improved compression ratio. In addition, the engine fully warms up in less time and also experiences significantly less friction.
Please read up on Jim Buttera’s story and why Buttera Motors has been a trusted German automotive shop for over 60 years and counting. Leave it to us for all Audi and VW repair work. Remember, German vehicles have a different construction under the hood and require maintenance from a specialist. TFSI engine or otherwise, all Audi and VW cars require a level of care a general auto shop may not be able to provide.
