| abstract | 502,171. Motor fuels. LEO CORPORATION. July 7, 1937, No. 18918. Convention date, July 13, 1936. [Class 91] Motor fuel contains a total of up to 0À085 per cent by weight of one or more #-diketone derivatives of the following metals, whereby no immediate anti-knock effect is produced but a deposit is gradually formed in the engine by continued use which deposit is effectively anti-knock. The metal may be cobalt, nickel, iron, manganese, copper, uranium, molybdenum, vanadium, zirconium, beryllium, platinum, palladium, thorium, chromium, aluminium, and cerium or other rare earth metal. The engine may first be run with fuel containing the higher percentages, e.g. 0À04-0À75 of dikotone derivative to build up the deposit, then on fuel containing only sufficient derivative e.g. 0À001-0À04 per cent to maintain the deposit and/or even for some. time on fuel containing no diketone derivative. Lead alkyl compounds, e.g. 0À1-5À0 cc. of lead tetraethyl per gallon, and non-corrosive organic sulphur compounds, e.g. 0À01-2À0 per cent of methyl, ethyl, or butyl sulphides or disulphides, carbon disulphide, or cyclic sulphur compounds may also be present. The preferred diketone compounds are the acetylacetonates, propionyl-acetonates, and formylacetonates; they may be halogenated. Fuels specified are gasolene, benzene, kerosene, fuel oils, alcohols, and mixtures thereof. For example, 0À04 per cent of a mixture of the propionyl-acetates of nickel, cobalt, and cerium with the acetyl-acetonates of thorium, zirconium, uranium, and chromium, with or without 2 cc. of tetraethyl lead or 7À5 cc. per callon of CS2, is used with gasolene. Specification 287,192, [Class 91], is referred to. The Specification as open to inspection under Sect. 91 describes the invention broadly as the use of fuel containing so small a concentration of organo-metallic compound that it has no effect on the combustion of the fuel but during continued operation of the engine forms therein a catalytic deposit improving the combustion. Reference is made to the use of proportions higher than 0À085 per cent ; and specified metallic compounds include amyl amine nickel chloride, manganese naphthenate, and palladium diethyl sulphide. This subject-matter does not appear in the Specification as accepted. |
