Definitions

  • the invention relates to a fuel for use in internal combustion engines according to the spark and compression ignition principle with circulation lubrication in gears, hydraulics, clutches and. The like. Units in vehicles and work machines.
  • the invention therefore relates to a fuel which is primarily suitable for use in internal combustion engines based on the compression ignition or spark ignition principle, provided that they have a circulation lubrication system.
  • the operating fluid should also be particularly suitable from case to case in order to meet the requirements of units that utilize the drive energy generated in the internal combustion engines, such as, for example, manual transmissions, hydraulic systems, turbo couplings, and axle transmissions, regardless of whether the units and motors have separate or shared oil budgets.
  • the present invention thus includes the task of avoiding environmental pollution from operating materials in all phases of practical use and the technical performance in the above-mentioned units that has only been achieved or achievable with environmentally hazardous combinations of base oils and additives.
  • the weight fraction of the biodegradable base oil can preferably be between 80 and 95% and the weight fraction of the additives between 20 and 5%.
  • the base oil preferably consists of one or more biodegradable ester oils, in particular mixtures of different ester types, the invention in particular envisaging the use of only ester types whose biodegradability corresponds to at least 80% according to CEC-L-33-T-82.
  • the additives used can preferably be antioxidants, metal passivators, rust or corrosion inhibitors, viscosity index improvers, pour point depressants, scale inhibitors, detergents and dispersants, high-pressure and wear protection additives and / or friction modifiers or the like.
  • additive content As far as the additive content is concerned, it is crucial to forego the majority of the conventional components and their combinations used in technically demanding operating materials of the type mentioned, because these are predominantly environmentally hazardous and, moreover, cannot be combined with base oils according to the invention exclusively of the ester type.
  • all additives are non-toxic and not hazardous to the environment, they can preferably be defined based on their task. In particular, additives with multifunctional properties are preferred.
  • Phenolic and / or aminic antioxidants are preferably used as additives, insofar as these ensure the desired biodegradability and low toxicity.
  • the weight fraction of the antioxidants is preferably in the order of 1 to 6%.
  • the invention proposes in particular those listed in claims 14 to 21, as well as their preferred ones Parts by weight.
  • the ester oils used have a biodegradability of at least 80% in contrast to conventional mineral oil hydrocarbons of about 20%, the operating fluids according to the invention are classified in water hazard class WGK 0, in contrast to operating fluids based on conventional mineral oils and additives, which are classified in WGK2.
  • the evaporation losses according to NOACK are below 6% for the operating materials according to the invention, while, for example, mineral oil-based 10W base oils have evaporation losses of over 15%.
  • the low NOACK values lead to low oil consumption and low exhaust emissions, in particular to reduce particle emissions.
  • the viscosity-temperature behavior of the operating materials according to the invention can, for example, correspond to that of conventional engine oils of classes SAE 5W-40 or SAE 10W-40, analogous to the technical requirements.
  • the cold viscosity approaches that of a 5W motor oil.
  • the additive fraction of the novel additive system according to the invention can preferably be 5%.
  • the ash-forming components of the additives do not contain zinc, they are limited to a maximum of 50% of those in conventional motor and aggregate oils (sulfate ash maximum 0.6% by weight).
  • the individual components used in the additive system are only in the water hazard class WGKO or 1. No components are used in the operating materials according to the invention which are subject to labeling according to the Hazardous Substances Ordinance (Chemicals Act).
  • the performance of the universal oil according to the invention corresponds to the requirements contained in the specifications of relevant manufacturers and - insofar as the motor performance is concerned - to the internationally applicable CCMC or ACEA specifications, such as G5 / PD2 / D4.
  • the universal oils according to the invention have very special properties which result from the requirements of the gears, wet brakes, clutches, hydraulics and the like. Like.
