SEAT Glossary

All the details.

F

Fuel Stratified Injection - FSI

FSI® (Fuel Stratified Injection) is the name SEAT gives to petrol engines with direct fuel injection.
In direct fuel injection, the fuel is injected directly into the combustion chamber at a maximum pressure of up to 150 bar. The special geometry of the combustion chamber ensures optimum turbulence of the fuel-air mixture.

Due to its innovative engine technology, the FSI® engine is characterized by high efficiency and above-average efficiency. By adapting driving styles, fuel savings are up to 25 per cent greater compared to engines of the same power using conventional injection technology.
