Definitions
- the present invention relates to a fuel composition for vehicles comprising a spark ignition engine (or gasoline engine), which has improved performance both in terms of engine power and energy saving.
- the invention also relates to the use of such a composition in a spark ignition engine, to increase the power and / or to reduce the specific fuel consumption.
- Gasoline fuels for use in spark-ignition engines, particularly those of motor vehicles, must have sufficiently high octane numbers to prevent knocking phenomena.
- the octane number measures the resistance of a fuel used in a spark ignition engine to auto-ignition.
