    • PURPOSE: Provided are new fuel compositions and methods for minimizing deposits in compression ignition engines. CONSTITUTION: Effective dispersants for use in compression ignition fuels are described as are compression ignition fuels containing such dispersants. The invention includes a fuel composition comprising: (a) a compression-ignition internal combustion fuel; and (b) a Mannich dispersant additive formed from: (1) at least one alkyl-substituted hydroxyaromatic compound; (2) at least one aldehyde; (3) a primary or secondary amine; wherein the ratio of the alkyl-substituted hydroxyaromatic compound to the aldehyde is in the range of from 1:1.25 to about 1:2; and wherein the ratio of the alkyl-substituted hydroxyaromatic compound to the amine is in the range of from about 1:1.25 to about 1:2.
    • 目的:提供用于最小化压缩式点火发动机中沉积物的新燃料组合物和方法。 构成:用于压燃式燃料的有效分散剂被描述为含有这种分散剂的压燃式燃料。 本发明包括燃料组合物,其包括:(a)压燃点火内燃燃料; 和(b)曼尼希分散剂添加剂,由以下物质形成:(1)至少一种烷基取代的羟基芳族化合物; (2)至少一种醛; (3)伯胺或仲胺; 其中烷基取代的羟基芳族化合物与醛的比率为1:1.25至1:2; 并且其中烷基取代的羟基芳族化合物与胺的比例在约1:1.25至约1:2的范围内。
