摘要： A cast alloy article suitable for improving the combustion characteristics and efficiency of a liquid fuel is disclosed. This cast alloy article is chiefly characterized by having coarse and irregular surface contour of interspersed peaks, valleys and pores that provide for increased surface area for increased fluid contact and provide for increased turbulence in fluid flow. The article has interspersed dendritic areas of solid dendrites and interdendritic areas of solid metal that also provide maximum surface area contact and turbulence of fluid flow of a fluid that is passed over the surface thereof. This article is made by heating selected quantities of selected metals including copper, zinc, nickel and tin to a temperature of above about 2000.degree. F. but not in excess of 2400.degree. F. intermixing the heated metals, pouring the heated metals into sand mold of a particular mesh to accomplish a coarse and irregular contour with pores and retaining the poured body at a temperature between about 2000.degree. F. and 800.degree. F. for a period of at least 24 hours to form solid dendrites. A cast alloy body of cylindrical form with longitudinal flutes or grooves in a tubular casing has liquid fuel passed through the casing and in contact with the body. An increase in zinc from about 23% to about 28-30% results in markedly higher electrical conductivity. A fuel filter has four of the cores arranged symmetrically about a longitudinal center line of a housing to form a longitudinal flow passage. Metal particles of the same material as the core surround the cores. An intermediate fuel filter between the housing and metal particles and at the inlet and outlet ends of the housing remove impurities from the filter. The fuel is passed over the cores and metal particles in passing between the inlet and outlet.
