Low-lead gasoline fuel, e.g. useful in engines for aircraft or racing vehicles, comprises defined amounts of isoparaffins with 4 or 5 carbon atoms and isoparaffins with 6-9 carbon atoms
Low-lead gasoline fuel, e.g. useful in engines for aircraft or racing vehicles, comprises defined amounts of isoparaffins with 4 or 5 carbon atoms and isoparaffins with 6-9 carbon atoms
Fuel with a lead content of 0.56 g/l or less comprises isoparaffins (I) with 4 or 5 carbon atoms, isoparaffins (II) with 6-9 carbon atoms and optionally alkylaromatic hydrocarbons (III) with 6-11 carbon atoms. The fuel contains 45-85 vol.% of (II) and has a (I)/(II) volume ratio of 0.1-0.6. An Independent claim is also included for producing a high-octane fuel with a low lead content by mixing (I), (II) and optionally (III) in amounts such that the fuel contains 45-85 vol.% of (II) and has a (I)/(II) volume ratio of 0.1-0.6.
