    摘要： A diesel fuel containing an additive which improves the combustion of soot, for reducing the pollutant emission in the combustion exhaust gases from diesel engines by discontinuous burning-off of soot which has been precipitated in the exhaust gas filter, is described. For this purpose, a lithium, sodium or potassium salt of an aliphatic or aromatic alcohol, of a phenol, of an aliphatic acid or of a naphthoic acid, phenylacetic acid or cinnamic acid is added, singly or as a mixture, to the diesel fuel before the combustion of the latter in the internal combustion engine. As a result of the addition of the alkali metal salts, the ignition temperature of the soot precipitated in the particle filter is reduced, and the soot is oxidized at a temperature which is considerably lower than the normal ignition temperature. The regeneration range for the particle filter is therefore reached much more frequently in real running practice. This avoids a critical filter loading with soot, which can lead to filter damage during burning off. A further advantage of the process described is that, according to present knowledge, no additional substances with a health risk are emitted during running as a result of the addition of these alkali metal salts to the diesel fuel.

    摘要翻译： 描述了含有改善烟灰燃烧的添加剂的柴油燃料，用于通过在废气过滤器中沉淀的烟灰的不连续燃烧来减少来自柴油发动机的燃烧废气中的污染物排放。 为此目的，将单独或作为混合物将脂族或芳族醇的脂族或芳族醇，脂肪酸或萘甲酸，苯乙酸或肉桂酸的锂，钠或钾盐加入到柴油中 在后者在内燃机中的燃烧之前。 作为添加碱金属盐的结果，在颗粒过滤器中沉淀的烟灰的点火温度降低，并且烟灰在比正常点火温度低得多的温度下被氧化。 因此，在实际运行实践中，更频繁地实现了颗粒过滤器的再生范围。 这样可以避免过滤装载烟尘的过滤器，这可能导致燃烧过程中的过滤器损坏。 所描述的方法的另一个优点是，根据现有的知识，由于向柴油燃料中加入这些碱金属盐，所以在运行期间不会发出具有健康风险的其它物质。
