Turbo fuel stratified injection
This article needs additional citations for verification. (August 2009) |
Turbo fuel stratified injection (TFSI) denotes a type of forced-aspiration ("turbo") engine where the fuel is pressure-injected straight into the combustion chamber. FSI (VAG) direct injection technology increases the torque and power of spark-ignition engines, makes them as much as 15 percent more economical and reduces exhaust emissions.[1]
Advantages
Some advantages of TFSI engines:
- Injection pressure can be regulated
- Better fuel distribution and better fuel charge inside the combustion chamber
- During the injection process the fuel gets evaporated, cooling the cylinder chamber
- Higher compression ratios, which translates into more power
- Increased fuel combustion efficiency
- Higher power during pick-up of vehicle.
