Method for improving fuel efficiency in combustion chambers

A method of improving fuel efficiency in combustion chambers for enhancing the combustion of hydrocarbon fuels comprising introducing a gold substance comprising a single vaporous gold compound or a mixture of vaporous gold compounds, with or without other catalysts, via a vaporous transport into the flame zone of a combustion chamber substantially homogeneously, such that said gold substance is held by gases in the flame zone before and during the combustion of the fuel, and the gold substance is thereby ionized prior to or during said combustion, and the gold substance contains about 8-24 micrograms of gold per kilogram of fuel.

A method of improving fuel efficiency in combustion chambers for enhancing the combustion of a hydrocarbon fuel comprising introducing at least one vaporous gold compound via a vaporous transport into the flame zone of a combustion chamber substantially homogeneously, the fuel contains at least one vaporous platinum compound in a concentration range of 0.15-225 micrograms of platinum per kilogram of fuel, such that a mixture of the gold and the platinum compounds is held by gases in the flame zone before and during combustion of the fuel, and the gold and the platinum compounds are thereby ionized prior to or during said combustion, and providing that said at least one gold compound has a concentration of about 4-24 micrograms of gold per kilogram of fuel.
