Claim:
1. A method of reducing the particulate emission from an internal combustion engine comprising the steps of: providing a base fuel having an aromatic content of at least about 10% by volume; adding into the base fuel an amount of an octane enhancer to form a fuel formulation, wherein the fuel formation containing the octane enhancer and the base fuel has an aromatic content that is less than the aromatic content of the base fuel without the octane enhancer; wherein (1) the particulate emission from combustion of the fuel formulation as measured by particle number (PN) (both solid and volatiles) is reduced as compared with particulate emission from the combustion of the base fuel, and wherein (2) the octane number of the fuel formulation is substantially the same or higher than the octane number of the base fuel without the octane enhancer.
