All About Audi’s TFSI Engine in Bothell

buttera-motors-6Some 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.
