The at least first component comprises a hydrogen bond acceptor and the at least second component comprises a hydrogen bond donor. The eutectic mixture includes an equilibrium phase between the at least first component and the at least second component. The equilibrium phase does not exhibit physical characteristics of the at least first component in an unmixed state and the at least second component in an unmixed state. The at least first component and the at least second component form an intermolecular interaction between each other sufficient to prevent crystallization of the at least first component and the at least second component in the eutectic mixture.

摘要： The objective is to provide lubrication oil and internal-combustion engine fuel for reducing the fuel consumption and for reducing carbon dioxide and other exhaust gas components. The lubrication oil is injected with lubrication oil impregnating agent composed of dimethylalkyl tertiary amine in the range from 0.01 to 1 volume % and desirably in the range from 0.1 to 0.5 volume %. Petroleum oil fuel is injected with fuel oil impregnating agent composed of dimethylalkyl tertiary amine in the range from 0.5 to 1 volume %. The petroleum oil fuel is light oil, kerosene, gasoline, or Bunker A. Any one or both of these lubrication oil and petroleum oil fuel is/are used for an internal-combustion engine.
