Abstract
Abstract A solution of a halogenated hydrocarbon when added in amounts of from about 1 to 2 parts per thousand by volume to hydrocarbon fuels improves combustion and increases fuel efficiency. The presence of a small amount of a hydroperoxide in combination with the halogenated hydrocarbon improves the starting characteristics of diesel fuel and further improves combustion efficiency.
