• Lubricating greases containing antimony dithiocarbamates

  Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance. It has now been found by using small amounts of either ammonium dithiocarbamate or zinc dithiocarbamate in combination with the antimony dithiocarbamate (SbDTC), a lower amount of SbDTC can be used in the lubricating composition while still maintaining excellent or exceptional EP protection. To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.

  锑二硫代氨基甲酸盐被认为在润滑剂组成中，如润滑脂中提供极压（EP）保护。然而，有一种希望在保持可接受的EP性能的同时减少在这种组成中使用的锑量的愿望。现已发现通过使用少量的氨基硫代氨基甲酸盐或硫代氨基甲酸锌与锑二硫代氨基甲酸盐（SbDTC）的组合，可以在润滑剂组成中使用更少的SbDTC，同时仍然保持出色或卓越的EP保护。为了抵消SbDTC和氨基硫代氨基甲酸盐组合物的腐蚀作用，已经发现含有羧酸基团的化合物可以有效避免铜腐蚀。

  Fuel compositions for internal combustion engines, and more particularly, fuel compositions for use in fuel-injected internal combustion engines are described. The fuel compositions comprise a major amount of a liquid hydrocarbon fuel and a minor, property-improving amount of a hydrocarbon-soluble dispersant prepared generally by the post-treatment of a nitrogen-containing composition with mono- and polycarboxylic acids which may be aliphatic or aromatic carboxylic acids although aromatic polycarboxylic acids are preferred. The nitrogen-containing compositions which are post-treated in accordance with the present invention are obtained by reacting an acylating agent with alkylene polyamines or alkanol amines. When fuel conpositions of the present invention are utilized in internal combustion engines, and in particular, fuel-injected internal combustion engines, the amount of solid deposits of the various parts of the internal combustion engines are reduced. In particular, the use of such fuels prevents or reduces intake system deposits and injector nozzle deposits. Accordingly, methods for reducing or preventing the buiid-up of deposits in internal combustion engines also are described.

  本文描述了用于内燃机的燃料组合物，特别是用于燃油喷射内燃机的燃料组合物。这些燃料组合物包括主要量的液态碳氢化合物燃料和少量的可改善性能的碳氢化合物可溶性分散剂，后者一般是通过用单羧酸和多羧酸对含氮组合物进行后处理而制备的，单羧酸和多羧酸可以是脂肪族或芳香族羧酸，但芳香族多羧酸更可取。根据本发明进行后处理的含氮组合物是通过酰化剂与亚烷基多胺或烷醇胺反应获得的。将本发明的燃料组合物用于内燃机，特别是喷射式内燃机时，可减少内燃机各部件的固体沉积物。特别是，使用这种燃料可以防止或减少进气系统沉积物和喷油器喷嘴沉积物。因此，还介绍了减少或防止内燃机沉积物形成的方法。
