Equipment for exhaust gas detoxification in internal combustion engines

Claim 1

In equipment for exhaust gas detoxification of internal combustion engines of the type that includes an exhaust system with an exhaust manifold and an exhaust pipe and at least one thermal or catalytic reactor within the exhaust system, the improvement comprising: a heat pipe within which a working fluid flows; said heat pipe containing three zones, a first zone serving as an evaporation zone and accepting heat from the exhaust gas, a second zone serving as the transport zone for the transport of the working medium between the first and third zones and a third zone serving as a condensation zone and giving off heat to its surroundings, said condensation zone including at least one secondary, independently operating, heat pipe connected to the condensation zone in the reactor; a radially permeable capillary tube lying within the first mentioned heat pipe such that through and along its interior the working medium flows in a vapor phase towards the condensation zone and along its outside the working medium flows in a liquid phase toward the evaporation zone; and flow-scoops disposed within the exhaust system upstream of the reactor and serving to create a swirl of the exhaust gases for the purpose of improved heat transfer in the reactor.
