Abstract (en)
[origin: WO02102942A2] A fuel additive composition includes a reaction product of a succinic acylating agent and a polyamine having at least one condensable primary amine group where the reaction product has a ratio of the imide to amide infrared carbonyl absorption peak areas of about 1:0.0-0.6 and a water content of about 0.3 % or less by weight. The succinic acylating agent is prepared by thermal condensation of a highly reactive polyolefin with maleic anhydride or a reactive equivalent thereof. This fuel additive composition has a low chlorine content and is very effective in fuel compositions that include a normally liquid fuel in reducing deposits in the fuel intake system of an internal combustion engine.
