Definitions
- the present invention relates to gasoline compositions especially to gasoline compositions suitable as automobile fuels and associated with low particulate emissions, the present invention also relates to the use of alcohols chosen among linear or branched secondary alcohols comprising 3 to 7 carbon atoms, for example isopropanol, in gasoline compositions to reduce particulate emissions.
- alcohols chosen among linear or branched secondary alcohols comprising 3 to 7 carbon atoms, for example isopropanol, in gasoline compositions to reduce particulate emissions.
- On-road vehicles are an important source of particulate matter emissions. Especially, particulate matter emissions from motor vehicles are of particular importance in urban areas where emissions occur in close proximity to populations. Once inhaled, these particles can affect the heart and lungs and cause serious health effects.
- Particulates are generated in the combustion chamber and then emitted through the exhaust system.
- Norm Euro6C of the European Union requires that gasoline engines emit less than 4.5 mg/km of particulate matter in mass and less than 6.10 11 per km in number. Reducing particulate emissions is thus of great interest.
- the reduction of the particulate emission can be addressed by the engine-fuel system or through the exhaust system.
- Three ways of reducing particulate matter emissions are available:
- oxygenate compounds for example ethanol and ethyl tertiary butyl ether (ETBE)
- EBE ethyl tertiary butyl ether
- a second challenge is also to obtain the maximum reduction of particulate emissions while achieving the highest greenhouse gases emissions reduction in terms of CO 2 equivalents through the incorporation of a maximum amount of biobased gasoline components.
- An object of the invention is thus to provide a gasoline composition enabling to reduce particulate emissions.
