Fuel composition and method for control of octane requirement increase |
| abstract |
The octane requirement increase phenomenon in a spark ignition internal combustion engine is controlled by introducing with the combustion charge a fuel composition containing an octane requirement increase-inhibiting amount of a compound selected from the group consisting of fused aromatics having at least 2, preferably between 3 and 5, aromatic rings with no heteroatoms substituted in the rings. The polynuclear aromatics can be either unsubstituted or substituted with groups other than an alkyl group. Usually the polynuclear aromatic is added to the fuel in an amount between about 0.1 and 5.0 weight percent of the fuel. In particular, anthracene and phenanthrene, and their non-alkyl derivatives, provide effective octane requirement increase-inhibiting additives for unleaded gasoline. |
