What is the displacement of 45tfsi?

[LeJoshua]

45tfsi has a displacement of 3.0L. The number 45 does not represent the car's displacement, but is a figure calculated based on the acceleration G-value. A larger number indicates a higher G-value during acceleration, meaning stronger power. The "tfsi" following 45 stands for Turbocharged Fuel Stratified Injection engine. The tfsi engine is an upgraded version of the fsi engine. The fsi engine can adopt stratified lean combustion to improve fuel economy. During stratified combustion, the surrounding air acts as a thermal insulation layer, reducing heat transfer loss through the walls. Lean combustion can also reduce the tendency for knocking, allowing the engine to use a higher compression ratio to enhance fuel economy.
