    摘要： A fuel additive according to the invention comprises a urethane compound of the formula

       wherein R 1 is hydrogen or a C 1 - C 30 hydrocarbon group, R 2 , R 3 , R 4 and R 5 each are hydrogen or a C 1 - C 10 hydrocarbon group and at least one of them is a group of formula (II) below, R 6 is a C 2 - C 6 alkylene group, a is an integer of 1 - 100, b is an integer of 0 - 100, the sum of a and b being equal to 1 - 200, c is an integer of 1 - 3, d is an integer of 0 - 2, the sum of c and d being equal to 3, and X is selected from the group consisting of hydrogen, a C 1 - C 30 hydrocarbon group, a group of formula (III) below and a group of formula (IV) below;
       said formula (II) being represented by

       wherein R 7 and R 8 each are hydrogen, a C 1 - C 10 hydrocarbon group or a C 2 - C 10 alcoxyalkyl group, R 9 is a C 2 - C 6 alkylene group or a C 4 - C 10 alkylene group having an alkoxyalkyl substituent, R 10 is hydrogen or a C 1 - C 30 hydrocarbon group, and e is an integer of 0 - 50;
       said formula (III) being represented by

       wherein R 11 is a C 2 - C 6 alkylene group, R 12 is hydrogen or a C 1 - C 4 alkyl group, R 13 is hydrogen or a C 1 - C 30 hydrocarbon group, and f is an integer of 1 - 5;
       and said formula (IV) being represented by

       wherein R 14 is a C 2 - C 6 alkylene group, R 15 , R 16 , R 17 and R 18 each are hydrogen or a C 1 - C 10 hydrocarbon group, Y is a methylene group, a C 1 - C 10 hydrocarbon-substituted methylene group, an imino group, a C 1 - C 10 hydrocarbon-substituted imino group or oxygen, g is 1 if d is equal to 1 and 0 or 1 if d is equal to 2, and if g is equal to 0, N here corresponds to N in formula (I).
    The inventive additive when blended with a gasoline serves to suppress sludge or deposits in fuel intake systems or combustion chambers for example of an automobile engine.
