Fuel additive mixtures for gasolines with synergistic ivd performance |
摘要 |
Novel fuels for gasoline engines comprise a synergistic mixture of a detergent additive component (A) and a synthetic carrier oil component (B), i) the detergent additive component (A) comprising at least one compound having a basic nitrogen atom which is substituted by a hydrocarbyl radical having a number average molecular weight of from about 500 to 1 300, and the detergent additive component (A) being contained in the fuel in an amount of from about 30 to 180 ppm by weight; and ii) the carrier oil component (B) comprising at least one compound of the following formula I <?in-line-formulae description="In-line Formulae" end="lead"?>R-O-(A-O)x-H (I)<?in-line-formulae description="In-line Formulae" end="tail"?> where R is a straight-chain or branched C<SUB>6</SUB>-C<SUB>18</SUB>-alkyl group; A is a C<SUB>3</SUB>- or C<SUB>4</SUB>-alkylene group; and x is an integer from 5 to 35; the carrier oil component (B) being contained in the fuel in an amount of from about 10 to 180 ppm by weight.
