The invention is related to a method and a device for recirculation of a part of exhaust gases from an exhaust pipe (6, 9) of a diesel engine (1) to the inlet of the engine, the exhaust gases being diverted from the exhaust pipe (6, 9) and directed through a recirculation conduit (10) to a controllable valve device (12) arranged between the engine and the air intake (2) thereof for allowing supply of air/recirculated exhaust gases in a desired relation to the combustion chamber of the engine (1). The invention also relates to a particular valve having two controllable inlets, said valve being useful in the method or device according to the invention, and a regulation method and device for regulating the air/fuel relation of a diesel engine.
La présente invention concerne un procédé et un dispositif permettant de recycler une partie des gaz d'échappement émanant du tuyau (6, 9) d'échappement d'un moteur diesel (1) vers l'entrée du moteur, les gaz d'échappement étant déviés du tuyau (6, 9) d'échappement pour être conduits, via une conduite (10) de recirculation, vers un dispositif (12) à soupapes réglables disposé entre le moteur et l'admission (2) d'air dudit moteur, de manière à permettre l'alimentation en air/gaz d'échappement recyclés de la chambre de combustion du moteur (1) selon un rapport désiré. L'invention concerne également une soupape particulière à deux entrées réglables, ladite soupape étant utilisée dans le procédé ou dispositif selon l'invention, ainsi qu'un procédé et un dispositif de régulation destiné à réguler le rapport air/carburant dans un moteur diesel.
