What does 40tfsi mean?

[Kieran]

40tfsi represents the g-value of the engine, which better reflects the car's acceleration. The 't' in tfsi stands for turbocharging technology, while 'fsi' refers to the fuel stratified injection engine. Stratified fuel injection technology is a type of lean-burn technology for engines, which allows for a lower gasoline content in the engine's air-fuel mixture, improving fuel efficiency. At the same time, this technology can also reduce the engine's fuel consumption. FSI can inject fuel directly into the combustion chamber, reducing the engine's heat loss, thereby increasing output power and reducing fuel consumption, benefiting both fuel economy and power performance.
