Abstract

Pot d'échappement pour empêcher la pollution atmosphérique, destin à être raccordé à un moteur thermique, qui permet d'obtenir une épuration parfaire des gaz d'échappement avant leur expulsion. On a prévu dans ce pot des lamelles planes pourvues de pointes ou d'éléments métalliques de très faible épaisseur, qui renferment des âmes en ferrite ou en graphite Ces âmes se réchauffent jusqu'à des températures très élevées par le rebondissement des particules non brûlées des gaz d'échappement provenant du moteur, qui sont de surcroît accélérées du fait des petites dimensions des chambres à turbulence. L'oxydation qui se produit ainsi assure une excellente épuration des gaz.Exhaust to prevent atmospheric pollution, intended to be connected to a heat engine, which allows to obtain a perfect purification of the exhaust gases before their expulsion. Flat lamellae provided in this pot are provided with points or very thin metal elements, which contain ferrite or graphite cores. These cores heat up to very high temperatures by the rebounding of the unburned particles of the particles. exhaust gases from the engine, which are furthermore accelerated due to the small dimensions of the turbulence chambers. The oxidation which thus occurs ensures excellent gas purification.
