Abstract

Dispositif pour capter les vapeurs de combustible émanant du réservoir à combustible et de la cuve du carburateur d'un moteur à combustion interne. Ce dispositif comporte une boîte 26 d'emmagasinage de vapeurs de combustible reliée, d'une part, au réservoir 20 de combustible et à la cuve 18 du carburateur par des conduits respectifs 24, 28, et d'autre part, au passage d'admission 16, en aval du papillon des gaz, par un conduit de purge 62. En outre, la boîte 26 est reliée par un conduit 58 de mise à l'atmosphère à un lit supplémentaire 68 d'emmagasinage de vapeurs de combustible disposé dans le filtre à air 14 pour capter les vapeurs de combustible qui s'échappent de la boîte, ce lit 68 étant complètement purge par le courant d'air d'admission du moteur. Application aux moteurs d'automobiles.Device for capturing fuel vapors emanating from the fuel tank and the carburetor bowl of an internal combustion engine. This device comprises a fuel vapor storage box 26 connected, on the one hand, to the fuel tank 20 and to the tank 18 of the carburetor by respective conduits 24, 28, and on the other hand, to the passage of inlet 16, downstream of the throttle valve, by a purge duct 62. In addition, the box 26 is connected by a duct 58 for venting to an additional bed 68 for storing fuel vapors disposed in the air filter 14 for capturing the fuel vapors which escape from the box, this bed 68 being completely purged by the engine intake air stream. Application to automobile engines.
