Abstract
A fuel additive for middle distillate fuels is a mixture of at least one methyl, ethyl, propyl or butyl ester of a vegetable oil or a C16-C18 fatty acid, at least one alkyl ether of propylene glycol, a surfactant, and an antioxidant. A fuel additive for gasoline is a mixture of ligroin or toluene/xylene, at least one alkyl ether of propylene glycol, a surfactant, and tertiary amyl methyl ether.
Claims17
A fuel additive for use in middle distillate fuels, the additive comprising:
- at least one methyl, ethyl, propyl or butyl ester of at least one vegetable oil or of at least one C16-C18 fatty acid,
- at least one alkyl ether of propylene glycol,
- a surfactant, and
- an antioxidant.
A method of treating a middle distillate fuel, the method comprising the steps of
- providing a fuel additive comprising at least one methyl, ethyl, propyl or butyl ester of at least one vegetable oil or of at least one C16-C18 fatty acid, at least one alkyl ether of propylene glycol, a surfactant, and an antioxidant, and
- adding said additive to the middle distillate fuel in an amount of up to 0.1% by weight of the total composition.
A fuel additive for use in gasoline type fuels, the additive comprising:
- at least one of ligroin or toluene/xylene,
- at least one alkyl ether of propylene glycol,
- a surfactant, and
- tertiary amyl methyl ether.
A method of treating gasoline, the method comprising the steps of
- providing a fuel additive comprising at least one of ligroin or toluene/xylene, at least one alkyl ether of propylene glycol, a surfactant, and tertiary amyl methyl ether, and
- adding said additive to the gasoline in an amount of up to 0.1% by weight of the total composition.
