Abstract
What follows is a description of an improvement in equipment for the exhaust gas detoxification of internal combustion engines. An insulated heat pipe is provided which transfers heat from the engine's exhaust manifold to an exhaust gas reactor. The heat pipe contains a first zone serving as an evaporation zone, a second zone serving as a transport zone for transporting a working medium between the first zone and a third zone. The third zone serves as a condensation zone. The heat pipe has an interior capillary tube along which the condensed heat transfer medium flows toward the heat source and within which the vaporized medium flows toward the heat sink.
