ABSTRACT:
An apparatus (16) for preheating combustion fluids such as air, fuel or fuel-air mixtures upstream of the combustion chamber in an internal combustion engine (10). The apparatus (16) generally includes a heat exchanger (18) and an assembly (46) for heating the heat exchanger. The improvement involves constructing the heat exchanger (18) from a plurality of closely-packed beads (20) each having a spherical shape and each comprised of homogeneous aluminum filling the entire space within the outer spherical shape to provide a high surface area heat exchanger for heating the combustion fluid as the fluid passes around the beads.
