Definitions

  • This invention relates to a diesel fuel additive composition
  • a diesel fuel additive composition comprising: (a) a detergent component selected from the group consisting of (i) a reaction product component of a substituted hydrocarbon and an amino compound, and (ii) a polybutylamine or polyisobutylamine; and (b) a fuel conditioner component comprising (i) a polar oxygenated hydrocarbon compound, and (ii) an oxygenated compatibilizing agent, for use in bulk production of diesel fuels for improving performance.
  • Diesel fuel impurities can arise from a variety of sources. They can form during refining or they can develop as a result of the oxidation which occurs during storage. Such impurities tend to be both soluble and insoluble materials having higher molecular weights and boiling points than the fuel, and which manifest themselves in the engine as colors or gums. Impurities can also be introduced into the fuel during handling or during storage from corrosion of storage vessels. Impurities can even take the form of other additives intentionally introduced by the manufacturer to solve or prevent some particular problem or improve the fuel itself, such as, for example, anti-oxidants, rust preventative, etc.
  • any of these impurities can cause deposits to from in the fuel system of compression ignition engines, and, in particular, in the fuel injectors. These deposits coat or adhere to injector parts and cause injector sticking, injector tip fuel metering passage fouling, nozzle hole plugging, leakage past critical surfaces, and delayed injection (and, hence, delayed start of combustion).
  • These problems result in significantly increased engine noise, smoke emissions, misfiring, low temperature or cold start problems, and idle roughness, and decreased power output and fuel economy. It is believed that these engine problems are the result of long ignition delays, significantly contributed to by deposits, causing an excessively rapid pressure rise in the cylinder once combustion does occur. Recent evidence suggests that the long delay provides the time for certain chemical reactions to take place in the atomized fuel charge prior to ignition, resulting in products which burn exceedingly rapidly once combustion begins, thereby causing the undesirable rapid pressure rise, and the resultant problems.
  • the additive comprises a detergent component and a fuel conditioner component, which synergistically interact to reduce fuel consumption in diesel engines.
