Abstract

La invención se refiere a un sistema de purificación de los gases de escape para la disminución de la emisión de hidrocarburos durante el arranque en frío de máquinas motrices de combustión interna. El sistema de purificación de los gases de escape contiene un absorbedor de hidrocarburos y un sistema de catalizador postconectado, el cual puede consistir en un catalizador de tres vías individual o de una combinación decatalizadores de oxidación, reducción y/o de tres vías en uno o en varios lechos. Las emisiones de hidrocarburos pueden disminuirse considerablemente durante la fase de arranque en frió por la utilización de catalizadores de oxidación o de tres vías, que frente a los catalizadores usuales presentan por lo menos una carga tan elevada como el doble con platino y/o paladio.
