ABSTRACT:
The control of the octane requirement increase phenomenon in a spark ignition, internal combustion engine is achieved by continuously or intermittently introducing with the combustion charge a fuel composition containing (a) an oil-soluble iron compound, (b) a volatile carboxylic acid or ester, and (c) a nonvolatile polar compound capable of solubilizing carbonaceous engine deposits, wherein said nonvolatile polar compound is introduced either simultaneously with said oil-soluble iron compound and said volatile carboxylic acid or ester during the intermission. Preferably said nonvolatile polar compound comprises an oxidation resistant hydrocarbon moiety covalently connected to a polar moiety selected from the group consisting of primary and secondary amino, formamido and sulfo radicals.
