ABSTRACT:
A method and apparatus for preheating combustion fluids such as air, fuel or fuel-air mixtures upstream of a combustion chamber (12) in an internal combustion engine (10). The apparatus generally includes a heat exchanger (18) and an assembly (30) for heating the heat exchanger. The improvement involves the use of reticulated foam metal as the heat exchanger (18) to provide a very high heating surface area (19) for thoroughly heating the fluids as the fluids pass through the reticulated foam metal.
