    摘要： The present invention relates to methods of fueling an internal combustion engine, and composition, that provide improved nitrogen-free detergency in the engine, particularly in the area of injector deposit control. The present invention also provides methods of providing both improved detergency and improved corrosion inhibition, while avoiding compatibility problems with fuels and/or while limiting the amount of nitrogen delivered to the fuel from the deposit control additive.

    摘要： The present invention is directed to a method to clean up or keep clean the fuel system of a direct injection spark-ignited engine by operating the engine with a fuel composition that includes a liquid fuel and a fuel additive composition. The fuel additive composition useful in the present invention has at least one nitrogen-containing dispersant and optionally a fluidizer where the dispersant has a specific lipophilic parameter and the dispersant or the dispersant and the fluidizer have a specific hydrophilic-lipophilic parameter, the dispersant provides about 0.15 to about 50 ppm by weight nitrogen in the fuel composition, and the fluidizer and/or the dispersant provide about 10 to about 10,000 ppm by weight active components in the fuel composition. The method of the present invention is effective in controlling deposits in fuel injectors and combustion chambers of a direct injection spark-ignited engine.

    摘要： The present invention is directed to fuel additive compositions of detergents combined with fluidizers and to hydrocarbon fuel compositions containing these fuel additive compositions. The fuel additive compositions of the present invention combine a Mannich detergent, formed from reaction of an alkylphenol with an aldehyde and an amine, with a fluidizer that can be a polyetheramine or a polyether or a mixture thereof and, optionally, with a succinimide detergent. Fuel compositions containing these fuel additive compositions are very effective in reducing intake valve deposits in gasoline fueled engines, especially when the weight ratio of detergent(s) to fluidizer(s) is about 1:1 on an actives basis.
