Invention Patent "FUEL COMPOSITION, PROCESS TO REDUCE DEPOSITS IN THE ENGINE, IN AN INTERNAL COMBUSTION ENGINE, CONCENTRATED WITH FUEL AND COMPOUND". Fuel composition that contains a greater amount of hydrocarbons that boil in the range of gasoline or diesel, and an effective amount of deposit control of an aromatic poly (oxyalkylene) ester that has the formula (I) where A ~ 1 ~ is nitro-amino, N-alkyl, independently, contains 1 to 6 carbon atoms; R ~ 1 ~ and R ~ 2 ~ are, independently, hydrogen, hydroxy, lower alkyl or lower alkoxy; R ~ 3 ~ and R ~ 4 ~ are, independently, hydrogen or lower alkyl in each -O-CHR ~ 3 ~ -CHR ~ 4 ~ unit; R ~ 5 ~ is hydrogen, alkyl of 1 to 100 carbon atoms, phenyl, aralkyl having 7 to 100 carbon atoms, or an acyl group of the formula: (II) or (II) where R ~ 6 ~ is alkyl having 1 to 30 carbon atoms, phenyl, aralkyl having 7 to 36 carbon atoms or alcaryl having 7 to 36 carbon atoms; R ~ 7 ~ and R ~ 8 ~ are, independently, hydrogen, hydroxy, lower alkyl or lower alkoxy; A ~ 2 ~ is nitro, amino, N-alkyl-amino in which the alkyl group contains 1 to 6 carbon atoms, or N, N-dialkyl-amino in which each alkyl group independently contains 1 to 6 carbon atoms ; n is an integer from 5 to 100, and x and y are each independently, integers from 0 to 10. |
