Abstract

The cartridge, for removing carbon monoxide, nitrogen oxides and unburned hydrocarbons, has a metallic casing with a gas compression chamber at its upstream end followed by the non-flammable filter made of asbestos. The asbestos filter is followed by an antacid filter made of calcium carbonate, which absorb nitrogen compounds. The final part may consist of a platinum sponge or foam or an absorbent material, e.g. wood charcoal, crushed to form lumps approximately the size of a cherry.

Description

Les emissions de gaz d'écnappement - de moteurs à ex:clDsion notamment donnent lieu dans le monde entier à des règlements de plus en plus siègees portant sur la teneur en oxyde de carbone (CO)1, oxyde d'azote (NO), hydrocarbures imbrulés et sulfates. On en déduit dés lors, que les systèmes d'échappement doivent être complétés par des systèmes à post combustion catalytique neutralisant ou diminuant ces émissions nocives. C'est l'objet de la présente invention qui se présente sous forme de cartouches filtrantes amovibles et remplaçables. Il existe déjà, pour diminuer ces émissions toxiques des pots catalytiques destinés aux moteurs à explosion. Mais le pot catalytique est onéreux d'autant plus que, lorsqu'il est saturé ou encrassé, il est necessaire de le changer. Le dispositif suivant la présente invention est moins onéreux et plus fonctionnel et permettra, de plus, aux véhicules non équipés de pot catalytique de circuler les  Exhaust gas emissions - from engines such as clDsion in particular - are giving rise to increasingly stringent regulations around the world relating to the content of carbon monoxide (CO) 1, nitrogen oxide (NO), unburnt hydrocarbons and sulfates. We deduce from this, that the exhaust systems must be supplemented by catalytic post combustion systems neutralizing or reducing these harmful emissions. This is the object of the present invention which is in the form of removable and replaceable filter cartridges. To reduce these toxic emissions, catalytic converters intended for internal combustion engines already exist. But the catalytic converter is expensive all the more that, when it is saturated or dirty, it is necessary to change it. The device according to the present invention is less expensive and more functional and will also allow vehicles not fitted with a catalytic converter to circulate the

Il laisse tel quel le pot d'échappement ou "silencieux" classique; mais il fait usage, à l'extrémité du pot d'échappement, à l'endroit de l'expulsion des gaz, d'une cartouche à la fois amovible et remplacable, une recharge en somme, qui recueillera les gaz toxiques et que l'usager changera lorsqu'elle sera encrassée ou venue à saturation,  It leaves the classic muffler or "muffler" as it is; but it makes use, at the end of the exhaust pipe, at the place of the expulsion of the gases, of a cartridge both removable and replaceable, a refill in short, which will collect the toxic gases and that the the user will change when it is dirty or saturated,

La cartouche comporte une enveloppe metalique servant de magasin et s'adaptant par vissage ou autrement à l'etrémité du tuyau d'échappement. Intérieurement, elle comporte, à l'arrivée des gaz, une chambre de compression dans laquelle les gaz viendront d'abord se comprimer pour traverser plus aisément un filtre extracteur composé lui-même de plusieurs parties se superposant constituées par: 10. d'abord une matière poreuse ininflammable, comme par exemple des fibres d'amiante comprimées entre deux tamis métalliques. ensuite une matière antiacide et absorbante comme du carbonate de calcium en comprimés ( le calcium absorbe  The cartridge has a metal casing serving as a magazine and adapting by screwing or otherwise to the end of the exhaust pipe. Internally, it comprises, on the arrival of the gases, a compression chamber in which the gases will first come to compress in order to pass more easily through an extractor filter itself composed of several superimposed parts consisting of: 10. first a non-flammable porous material, such as asbestos fibers compressed between two metal screens. then an antacid and absorbent material such as calcium carbonate tablets (the calcium absorbs
