PURPOSE:To obtain a small stirling engine with an excellent engine performance by fastening a heating tube to a metal or ceramic body with a large void while a solid body with a small void is arranged at the upstream and downstream ends so as to jet a fuel gas into the solid body with a small void at the upstream end. CONSTITUTION:With an air chamber 27 above a solid body I 29, a plurality of fuel jet ports 30 are arranged to be opened into the solid body I 29 such as bubble metal with a relatively small void piercing a rectifying body 28 and under the solid body I 29, a solid body II31 such as bubble metal and metallic screen with a large void or porous ceramic body with an excellent heat conductivity is fastened on the surface of a heating tube 20 by blazing or metalization processing. On the downstream of the solid body II31, a solid body III32 is provided which is porous with a small void but relatively large in the thickness. Thus, the fuel jet ports 30 direct a jetting into the solid body I 29. |
