    • An anti-wear compression ignition fuel for use in diesel engines comprising (1) a monohydroxy alkanol having from 1 to 5 carbon atoms, and (2) a wear inhibiting amount of a straight chain aliphatic primary amine, e.g. oleyl amine. Optionally, said fuel composition may also contain an ignition accelerator such as an organic nitrate.It has recently been disclosed in Brazilian Patent Application No. P17700392 that alcohols, such as methanol and ethanol, can be substituted for conventional petroleum derived diesel fuels for burning in diesel engines, when used in combination with an ignition accelerator, such as ethyl nitrate or nitrite. Reportedly, the addition of alkyl nitrate or nitrite accelerators to the alcohol achieves a level of auto-ignition sufficient to operate in diesel engines. Unfortunately, these fuel compositions, devoid of any petroleum derived products, are notably deficient in lubricity or lubricating properties with the result that engine wear from the use of these fuels in internal combustion reciprocating diesel engines is a serious problem. Of particular concern are wear problems associated with the fuel injector mechanisms used in such engines. Wear problems have also been encountered in diesel engines operating on light diesel fuel oils are disclosed in U.S. Pat. No. 4,002,437.
    • 一种用于柴油发动机的抗磨压缩点火燃料,包括(1)具有1至5个碳原子的单羟基链烷醇,和(2)耐磨损量的直链脂族伯胺,例如, 油胺。 任选地,所述燃料组合物还可以含有点火促进剂,例如有机硝酸盐。 最近在巴西专利申请P17700392中公开了,当与点燃促进剂如硝酸乙酯或硝酸乙酯组合使用时,诸如甲醇和乙醇的醇可以代替常规的柴油发动机燃烧柴油, 亚硝酸盐 据报道,向醇中加入硝酸烷基酯或亚硝酸盐促进剂达到足以在柴油发动机中运行的自动点火水平。 不幸的是,没有任何石油衍生产品的这些燃料组合物显着地缺乏润滑性或润滑性能,结果是在内燃往复式柴油发动机中使用这些燃料的发动机磨损是严重的问题。 特别令人关注的是与这种发动机中使用的燃料喷射器机构有关的磨损问题。 在美国专利No.4,697,697中公开了在轻柴油燃料油上运行的柴油发动机中也遇到了磨损问题。 第4,002,437号。
