1.TFSI engine
TFSI turbine engine fuel injection engine is that it can be said to combine FSI engine and turbocharger. I.e. turbocharger (Turbocharger) + FSI
T as its TSI and the T, represents turbocharged, i.e. behind the FSI stratified fuel injection engine (Fuel Stratified Injection), S represents ldquo ; hierarchical rdquo ;, instead TSI meaning indicated supercharger. Both stratified injection TFSI engine, there turbocharger, the engine is an upgraded version of TSI.
However, the turbocharger at low rpm (1500 rpm or less), an idling phenomenon, high rotational speed (5000 rpm or more) of the turbine is actually not working, i.e. working range of the turbocharger only in the 1500 to 5000 switch between.
TSI is a dual plenum mass, i.e., combined supercharger and turbocharger, each other.
