Definitions

  • the present invention relates to novel quaternized polyetheramines and their preparation, Furthermore, the present invention relates to the use of these compounds as a fuel and lubricant additive. More particularly, the invention relates to the use of these quaternized nitrogen compounds as a fuel additive to reduce or prevent deposits in the injection systems of direct injection diesel engines, particularly in common rail injection systems, to reduce fuel consumption of direct injection diesel engines, particularly diesel engines with common rail injection systems. and to minimize the power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems.
  • the invention also relates to additive packages containing these polyetheramines; as well as with it additized fuels and lubricants. Furthermore, the invention relates to the use of these quaternized nitrogen compounds as an additive for gasoline fuels, in particular for improving the intake system cleanliness of gasoline engines.
  • direct-injection diesel engines the fuel is injected through a directly into the combustion chamber-reaching multi-hole injection nozzle of the engine and finely distributed (nebulized), instead of being introduced as in the classic (chamber) diesel engine in a vortex or vortex chamber.
  • the advantage of direct-injection diesel engines lies in their high performance for diesel engines and yet low consumption. In addition, these engines achieve a very high torque even at low speeds.
  • the diesel fuel is pumped from a pump with pressures up to 2000 bar into a high-pressure line, the common rail.
  • spur lines run to the various injectors, which inject the fuel directly into the combustion chamber.
  • the full pressure is always applied to the common rail, which allows a multiple injection or a special injection form. In the other injection systems, however, only a smaller variation of the injection is possible.
  • Injection in the common rail is essentially subdivided into three groups: (1) preinjection, which substantially achieves softer combustion, so that hard combustion noises ("nails") are reduced and engine running appears quiet; (2.) main injection, which is responsible in particular for a good torque curve; and (3.) post-injection, which provides in particular for a low NO x value.
  • preinjection which substantially achieves softer combustion, so that hard combustion noises ("nails") are reduced and engine running appears quiet
  • main injection which is responsible in particular for a good torque curve
  • post-injection which provides in particular for a low NO x value.
  • the fuel is not burned in the rule, but evaporated by residual heat in the cylinder.
  • the resulting exhaust gas / fuel mixture is transported to the exhaust system, where the fuel in the presence of suitable catalysts acts as a reducing agent for the nitrogen oxides NO x .
  • deposits can form under certain conditions, for example when using biodiesel-containing fuels or fuels with metal impurities such as zinc compounds, copper compounds, lead compounds and other metal compounds, the injection behavior of the Negatively affect the performance of the engine, ie in particular reduce the power, but in part also deteriorate the combustion.
  • the formation of deposits is further enhanced by structural developments of the injectors, in particular by the change in the geometry of the nozzles (narrower, conical openings with rounded outlet). For a permanently optimal functioning of the engine and injectors, such deposits in the nozzle orifices must be prevented or reduced by suitable fuel additives.
  • Fuel metering systems are contaminated by impurities caused by dust particles from the air, unburned hydrocarbon residues from the combustion chamber and the crankcase ventilation gases directed into the gasifier.
  • the first additive generation could only prevent the formation of deposits in the intake system, but not remove already existing deposits, whereas the modern additives of the second generation can cause both (keep-clean and clean-up effect) and especially because of their excellent thermal stability at higher temperature zones, namely at the inlet valves.
  • Such detergents which can originate from a large number of chemical substance classes, for example polyalkeneamines, polyetheramines, polybutene-Mannich bases or polybutene succinimides, are generally used in combination with carrier oils and in some cases further additive components, for example corrosion inhibitors and demulsifiers.
  • the carrier oils perform a solvent or wash function in combination with the detergents.
  • Carrier oils are usually high-boiling, viscous, thermostable liquids which coat the hot metal surface and thereby prevent the formation or deposition of impurities on the metal surface.
  • Detergent-effect fuel additives of the younger generation often have quaternized nitrogen groups.
  • Polyalkene substituted quaternized amines such as, in particular, quaternized polyisobuteneamines, and their use as detergent additives to reduce inlet valve deposits and as lubricant additives for internal combustion engines are disclosed in U.S.P. US 2008/0113890 described.
  • the US 6 331 648 B1 relates to specific quaternary etheramine compounds which incorporate a 1-ethyl-1,3-propylene unit between the alkoxylate chain and quaternary nitrogen.
  • the use of these compounds as anticorrosion or detergent additives in gasoline and diesel fuels is speculated, but without demonstrating their usefulness.
  • the EP 182 669 A1 describes halogenated or sulfur-containing alkoxylated quaternary ammonium compounds of the general structure [RO (R 1) x CH 2 CH (R 2 ) HNR 3 R 4 R 6 ] + A- wherein R 1 represents an alkylene oxide block.
  • R 1 represents an alkylene oxide block.
  • Preferred anions A- are chloride, methylsulfate and ethylsulfate.
  • the U.S. 4,564,372 . US 4,581,151 . US 4,600,409 and the WO 1985/000620 refer to alkyl halides quaternized, ie halogenated, polyoxyalkyleneamine salts in which polyoxyalkylene unit and amine unit via different linker groups, in particular amine linker of the type - C (O) -NH-.
  • Use as dispersants and corrosion inhibitors in fuels is postulated, but without actually demonstrating specific functions experimentally.
  • the additives according to the invention are superior to the known additives according to the prior art in several respects and can be used simultaneously in diesel and gasoline fuels. They are characterized by their advantageous cleansing and cleansing effect on various components of internal combustion engines, such as diesel engine injectors but also on intake valves and injectors of gasoline engines, and prevent the formation of combustion chamber deposits or eliminate ready formed combustion chamber deposits of internal combustion engines. In addition, they prevent the formation of deposits in fuel filters or eliminate already formed filter contaminants.
