Definitions

  • the invention relates to a methanol-based fuel which consists of undistilled technical methanol, water and dimethyl ether and other additives and to the use of the same in motorized garden tools.
  • Undistilled technical methanol contains e.g. Formaldehyde, methyl formate, dimethyl sulfide. Formaldehyde diacetal, formic acid, iron pentacarbonyl and other carboxylic acids and their esters.
  • the invention therefore relates to a methanol-based fuel, which may also contain higher alcohols, ethers, ketones and hydrocarbons or mixtures thereof, characterized in that the fuel consists of undistilled technical methanol containing 0.5-18% by weight of water and 0.5-12% by weight of dimethyl ether.
  • Dimethyl ether has the property that its low boiling point of -24 ° C improves the cold start behavior sufficiently. Although it was to be expected that the solubility of the dimethyl ether would be reduced by the stated water content of the methanol to such an extent that dimethyl ether as a cold start aid would evaporate too early, the long-term tests have surprisingly shown that dimethyl ether remains dissolved in the fuel in an amount sufficient to improve the cold start behavior . Although the causes of this are not fully understood, it is believed that hydrogen bonds cause this behavior.
  • the fuel according to the invention can also contain higher alcohols and ethers or their mixtures. Z are particularly suitable.
  • topped, undistilled methanol can also be used, with volatile impurities having been distilled off overhead.
  • Mixtures of distilled methanol, undistilled methanol and topped methanol can also be used.
  • z. B. diethyl ether and / or methyl tert-bytyl ether may be included.
  • Suitable corrosion inhibitors are e.g. Phosphoric acid esters combined with triazoles, inhibitors based on sodium benzoate, compounds such as 2- (5-aminopentyl) benzimidazole or commercially available products such as PFJ 876 from Ethyl Corp. i.a.
  • emulsifiers are glycols and glycol ethers, e.g. Ethylene glycol, propylene glycol, polyethylene glycol, their monoethers and diethers are suitable.
  • a suitable ignition control additive is e.g. B. Tricresyl phosphate.
  • the fuel according to the invention can also be used in two-stroke engines.
  • special lubricating oils are preferred, e.g. Lubricating oils based on poly-a-olefins.
  • the fuel according to the invention undoubtedly represents a very significant economic success for the operation of motorized vehicles, which improves the economic supply of engines with alternative fuels by a significant step, since the invention unexpectedly shows that the high technical and costly expense of working up by distillation technical methanol to pure methanol is not required for use as a fuel and a surprising improvement over the prior art is achieved in particular with regard to environmental pollution.
