Definitions
- TITLE Composition of fuel rich in aromatic compounds, paraffins and ether, and its use in motor vehicles
- the subject of the present invention is a fuel composition intended for vehicles comprising a spark-ignition engine (or gasoline engine), and which has advantageous properties.
- a subject of the invention is also the use of such a composition for supplying a spark-ignition engine, both in a conventional vehicle, in particular an automobile, and in a competition vehicle.
- Gasoline-type fuels that can be used in spark-ignition engines, in particular those of motor vehicles, must have sufficiently high octane numbers to avoid knocking phenomena.
- the octane number measures the resistance to auto-ignition of a fuel used in a spark-ignition engine.
- gasoline fuels marketed in Europe complying with the EN 228 standard, have a motor octane number (or MON, for Motor Octane Number) greater than 85 and a research octane number (or RON, of English Research Octane Number) of a minimum of 95. These fuels are suitable for the vast majority of automotive engines.
- a high volumetric compression ratio is particularly desired.
- One objective of the present invention is therefore to improve the performance of gasoline fuel compositions, in particular but not limited to fuel compositions intended for competition vehicles.
- the objective is to increase the energy content of the fuel, which will lead to an increase in the power of the spark-ignition engine, whether it is atmospheric, turbocharged, hybrid or not, during the combustion of the gasoline fuel composition in engine.
- compositions from bases and/or compounds of renewable origin, also called biobased compounds.
- octane enhancing additives are typically added to gasoline type fuel compositions.
