Abstract: An object of the invention is to provide a sulfide solid electrolyte material with high heat stability. In the invention, the object is achieved by providing a sulfide solid electrolyte material comprising an ion conductor having (i) a Li element and (ii) an anion structure containing at least a P element, wherein a main component of the anion structure is PS43?, and the ion conductor has the PS43? and PS3O3? as the anion structure, but has neither PS2O23? nor PSO33?.

Abstract: According to the present invention, the state of a liquid fuel such as diesel fuel is made a supercritical state by raising the pressure and the temperature of the fuel above the critical pressure and temperature. Then, the fuel is injected from the fuel injection valve into the combustion chamber of the engine in the supercritical state. When the fuel in the supercritical state is injected into the combustion chamber of the engine, it forms an extremely fine uniform mist in the entire combustion chamber. Therefore, the combustion in the engine is largely improved.
