  • Desensitized cetane improvers
    Patent number: 4473378
    Abstract: Compounds that are themselves effective cetane improvers in diesel fuel but are considered too explosion sensitive for safe handling can be rendered relatively nonsensitive by blending with C.sub.5 to C.sub.12 alkyl nitrates and the resulting blend is an effective cetane improver. An example is a 50--50 blend of 2-methyl-2-nitropropyl nitrate, a shock-sensitive compound, with isooctyl nitrate to give a relatively insensitive but very effective cetane improver.
    Type: Grant

    Assignee: Ethyl Corporation
    Inventors: John V. Hanlon, James B. Hinkamp
  • Synergistic cetane improver
    Patent number: 4448587
    Abstract: The cetane rating of diesel fuel is increased by addition of a small amount of the synergistic combination of (a) an alkyl-nitrate (e.g. octyl nitrates) and (b) the nitrate ester of an alkoxylated alcohol (e.g. ethoxyethyl nitrate).

  • Diesel fuel composition
    Patent number: 4417903
    Abstract: The cetane number of diesel fuel is increased by the addition of an aliphatic hydrocarbyl nitro nitrate additive such as 2-methyl-2-nitro-1-propanol nitrate (ester).
    Type: Grant

  • Fuel compositions containing iron pentacarbonyl
    Patent number: 4336033
    Abstract: An improved fuel composition comprising a major amount of hydrocarbons boiling in the gasoline boiling range, and a minor amount of iron pentacarbonyl capable of improving the octane number rating of the composition but insufficient to cause excessive wear in engine parts when the fuel composition is burned in an internal combustion engine.
