Embodiment

[0037] Emissions measurements were tested on three motor vehicles comparing lower octane (less than 86.7) gasoline to gasoline with an octane minimum of 87. The gasolines tested are listed in Table 1. These gasolines are produced from refinery streams or of the same composition as refinery streams. Refinery streams used are isomerate, heavy reformate and FCC naphtha, heavy resid and light alkylate where toluene can replace light reformate and mixed isohexane can replace light quality residual oil. Light reformed products are generally considered to be mainly C 7 -C 8 , which is mainly toluene, so toluene can replace it. Also mixed isohexane is considered to be similar to light resid. Note the relatively low olefin content of the fuels tested. This is because it is difficult to find suitable blending feedstocks that are low in sulfur and high in olefins. Low olefin content is not considered to have a fundamental effect on the validity of the test results. The gasolines ...

Abstract

An emission-reducing unleaded gasoline having at least one of an octane rating of less than about 86.7, a sulfur content of less than about 40 ppmw, and optionally containing oxygenates, which reduces emissions compared to gasoline having a minimum octane rating of 87. Provides a means for individual vehicles and fleets of vehicles to reduce emissions from internal combustion engines in motor vehicles. Also disclosed is a method of reducing emissions using a distribution network, and a system for reducing emissions through a combination of refineries and vehicles.
