ABSTRACT:
Certain chemical elements or compounds, smog inhibitors, added to combustible hydrocarbon-base fuels, can reduce, or eliminate, ozone, O.sub.3, an oxidant necessary for the formation of smog and its irritants. A test program demonstrated that atmospheric ozone was reduced an average of about 75% when exhaust gases derived from an automotive engine burning fuel containing an inhibitor were injected into a sealed chamber as compared to the same engine burning fuel containing no additive. In each of the tests using the fuel additive, ozone concentrations approached, or reached, zero for short periods of time, indicating the viability of this method of ozone, and therefore smog, control. This patent is for the purpose of controlling smog formation by the addition of smog inhibitors, such as, but not limited to, iodine or its compounds to hydrocarbon-base fuels prior to, or during, the combustion cycle of these fuels.
