<p>Fuel additive compositions for improving the combustion efficiency of an internal combustion engine, and thereby substantially reducing undesirable motor vehicle exhaust emissions as well as fuel consumption. The composition is composed of a bicyclic aromatic component selected from the group consisting of naphthalene, substituted naphthalene, biphenyl, biphenyl derivatives, and mixtures thereof, zinc oxide, and at least one group 8-11 metal oxide selected from the group consisting of iron oxide, copper oxide, cobalt oxide, ruthenium oxide, osmium oxide, and palladium oxide, all dispersed in a carrier liquid selected from the group consisting of a hydrocarbon fraction in the kerosene boiling range having a flash point of at least 100 °F and an auto-ignition temperature of at least 400 °F, a C1-C3 monohydric, dihydric or polyhydric aliphatic alcohol, and mixtures thereof. In a preferred embodiment the composition also contains magnesium oxide. In an alternate embodiment, the composition contains a mixture of magnesium oxide, zinc oxide and iron oxide, all dispersed in the carrier liquid. The present invention is also directed to processes for formulating a fuel blend for use in fueling an internal combustion engine as well as processes for operating an internal combustion engine with both an associated fuel chamber from which fuel is supplied to the engine and exhaust system for the emission of combustion products from the engine.</p> |
