    • A gas oil according to the present invention comprises a gas oil fraction, and has a sulfur content not higher than 0.05 wt %, and either or both of (1) a content of bicyclic and higher aromatic hydrocarbons in a range of from 3.5 wt % to 15 wt %, bicyclic and higher aromatic hydrocarbons having at least one side-chain C.sub.3-11 alkyl group amounting to at least 80 wt % of said first-mentioned bicyclic and higher aromatic hydrocarbons, and (2) a content of nitrogen-containing heterocyclic compounds in a range of from 80 ppm to 500 ppm, nitrogen-containing heterocyclic compounds having at least one side-chain alkyl group accounting for at least 90 wt % of said first-mentioned nitrogen-containing heterocyclic compounds. The gas oil according to the present invention, as a diesel fuel, can impart anti-wearing properties by simply adjusting its components without the need for incorporation of an additive such as an anti-wearing agent. It does not cause wearing of a fuel injection pump, has excellent storage stability and can be furnished as an economical gas oil. It can also be furnished as a gas oil suited for use especially in cold districts.
    • 根据本发明的瓦斯油包含粗柴油馏分,硫含量不高于0.05重量%,并且(1)双环和高级芳烃的含量为3.5重量% 至少15重量%,具有至少一个侧链C3-11烷基的双环和高级芳族烃占所述第一提到的双环和高级芳烃的至少80重量%,和(2)含氮的 80ppm至500ppm范围的杂环化合物,至少含有一个侧链烷基的含氮杂环化合物占所述第一提到的含氮杂环化合物的至少90重量%。 根据本发明的瓦斯油作为柴油燃料,可以通过简单地调节其组分而赋予抗磨损性,而不需要加入诸如耐磨剂的添加剂。 不会引起燃油喷射泵的磨损,具有良好的储存稳定性,并且可以作为经济的瓦斯油来提供。 它也可以作为适用于特别是在寒冷地区使用的瓦斯油来提供。
