Abstract
Description
La présente invention a pour but de remplacer le brevet precedent du pot d'échappement silencieux,et éliminer le taux de gaz avec du plomb nocif. Ce brevet déposé le 30 Juillet I9,G, accordé le I4 fevrier I972,portant le N 7028I75,valable 20 ans. The present invention aims to replace the previous patent of the silent exhaust pipe, and eliminate the rate of gas with harmful lead. This patent filed on July 30, I9, G, granted on I4 February I972, bearing the N 7028I75, valid for 20 years.
Ce brevet modifié,améliore le brûlage et procédé filtré, strictement maintenu le procédé de description déposé sur le brevet précédent. This modified patent improves the burning and filtered process, strictly maintaining the description process filed on the previous patent.
La présente invention a pour but d'éliminer les gaz non brûlés avant la sortie du pot d'échappement,sans adjonction de matière chimique ni modification apportée au moteur. The object of the present invention is to eliminate unburnt gases before leaving the exhaust pipe, without adding chemical material or modifying the engine.
Le brûlage commence dès la mise en marche du moteur jusqu'à atteindre la température de 300 degrès. Burning begins when the engine is started until the temperature reaches 300 degrees.
Si cette température descend au-dessous de 300 O brûleur est mis en route automatiquement dans le pot par un mano contact. If this temperature drops below 300 O the burner is automatically started in the pot by a pressure switch.
Le dispositif suivant l'invention comprend une chambre surchauffée anti-condensation dans laquelle arrive les gaz brûlés du moteur,puis une tuyère dans laquelle déboute des tubes co.zmuri -quants avec l'extèrieur qui procurent une arrivée d'air pur au débouché de la tyuère,une chambre de mélange dans laquelle circule le mélange d'air et de gaz d'échappemnt; des chicanes et une chambre de brûlage dans laquelle des gicleurs projettent le mélange sur une source de chaleur, telle qu'une bobine chauffée au rouge,d'où les gaz brillés sortent par des chicanes amrtissant le bruit à 1' échappement. The device according to the invention comprises an overheated anti-condensation chamber into which the burnt gases from the engine arrives, then a nozzle into which open co.zmuri -quant tubes with the exterior which provide a supply of pure air at the outlet of tyuère, a mixing chamber in which circulates the mixture of air and exhaust gases; baffles and a burning chamber in which sprinklers project the mixture onto a heat source, such as a red-heated coil, from which the burnt gases exit through baffles which reduce noise to exhaust.
Cn obtient ainsi une post-combustior complète des gaz d' échappement et une réduction notable du bruit. Cn thus obtains a complete post-combustion of the exhaust gases and a notable reduction in noise.
On décrira plus en détail çi-après,à tiQre d'exemple, indicatif et nullement limitatif,ur pot d'échappement cylindrique suivant l'invention en référence au dessin annexé sur leouel la figure I est tie vue en coupe longitudinale. There will be described in more detail hereinafter, by way of example, indicative and in no way limitative, ur cylindrical exhaust pipe according to the invention with reference to the attached drawing on which the figure I is a view in longitudinal section.
Les figures 2 et 3 sont des vues en coupe suivant II - II et partielle suivant III - III de la figure I A. Figures 2 and 3 are sectional views along II - II and partial along III - III of Figure I A.
Le pot proprement dit comprend un cylindre à double paroi ( 2 ) avec garniture isolante et anti-bruit,telle que la soie de verre ( 3 ).Les gaz d'échappement du moteur par la tubulure (4) et trarse le pot dans sa longueur dans le sens des flèches F pour déboucher à contre - sens dans une chambre chaude ( 5 ) art codensation,avec plaques inclinées perforées I 2 et se rendent par une tubulure ( 6 ) dans le sens des flèehes-F 2 et F 3,du ctté entrée du pot vers une tuyère troncônique (7) où ils sort mis er. The pot itself comprises a double-walled cylinder (2) with insulating and anti-noise lining, such as glass fiber (3). The exhaust gases from the engine through the pipe (4) and shrouds the pot in its length in the direction of the arrows F to lead in the opposite direction into a hot chamber (5) art codensation, with inclined perforated plates I 2 and go through a tube (6) in the direction of the arrows-F 2 and F 3, from the inlet side of the pot to a frustoconical nozzle (7) where they come out er.

Le filtre ( PL4 ) fig, B 4 coupe longitudinale,2ème partie do pot d'échappement.turbuience (arrow F4) in a chamber (9) receiving outside air intakes IC 2 in number for example: this mixture of burnt and unburnt gas crosses baffles I 3, and is distributed there by sprinklers I 4, in a chamber II, in which a hot source is provided, for example ur.e electric coil T 5
THE HARMFUL GAS FILTnE
The filter (PL4) fig, B 4 longitudinal section, 2nd part of the exhaust pipe.
L'assemblée des filtres consiste pour éliminer les résidus après brtlE±e des hydrocarbures ainsi que la quantité de plomb brillé. Le reste d'oxyde d'azote sortant par le pot d'échappement traversant le filtre pour perdre tout gaz nocif anti-pollution et anti-bruit. The assembly of filters consists in eliminating the residues after burning of the hydrocarbons as well as the quantity of lead burnt. The rest of the nitrogen oxide exiting through the exhaust pipe passing through the filter to lose any harmful anti-pollution and anti-noise gas.
Description du filtre
pour éliminer la totalité de l'oxyde d'azote il nécessite une quantité d'air pur pour un mélange pour déposer le nocif traversant une quantité de coke calibré et un tiss u de nylon filtrant.Filter description
to remove all of the nitrogen oxide it requires a quantity of pure air for a mixture to deposit the harmful agent passing through a quantity of calibrated coke and a filter fabric of nylon.
