Abstract
Liquid hydrocarbon-soluble rare earth chelates prepared from the novel ligand 2,2,7-trimethyl-3,5-octanedione when dissolved in fuels such as gasoline and diesel oil prevent formation and/or effect removal of carbonaceous deposits during the combustion thereof. The use of fuels containing these chelates promotes more efficient operations of devices such as internal combustion engines in which the fuels are burned by minimizing or eliminating the accumulation of harmful carbonaceous materials in the combustion chambers and by preventing knocking and/or other undesirable performance characteristics.
