Abstract (en)

[origin: WO9200443A1] The invention relates to a diesel engine fitted with a filter trap. The filter trap comprises a filter material (12) having embedded in it particles of a catalyst and disposed within the exhaust manifold (10) of the diesel engine immediately downstream of the exhaust ports. By-pass channels (34) are included in the filter material (12) to permit part of the gases to be directed for recirculation through the engine without passing through the filter material.

Abstract (fr)

L'invention se rapporte à un moteur diesel pourvu d'un piège de filtration. Le piège de filtration comprend un matériau filtrant (12) dans lequel sont incrustées des particules d'un catalyseur, et qui est placé dans le collecteur d'échappement (10) du moteur diesel immédiatement en aval des orifices d'échappement. Des canaux de dérivation (34) sont compris dans le matériau filtrant (12) afin de permettre à une partie des gaz d'être recirculée à travers le moteur sans passer à travers le matériau filtrant.
