Abstract
A Stirling engine adapted for automotive propulsion is disclosed using an improved preheater construction in the external heating circuit.The preheater construction is comprised of discrete cubicle modules arranged annularly about the engine burner with their inner faces in contiguous edge contact to define a close cylindrical space. The modules are totally ceramic with alternating orientation of finned ceramic wall fused together to define a cross-flow matrix. Static seal strips of woven ceramic material encased in a folded metal foil strip are retained against all of the edges of each module to facilitate cross-flow fluid connections.
