Abstract
Se describen sistemas de tratamiento de gases de escape para el tratamiento de una corriente de gas de escape de motores de gasolina. Los sistemas de tratamiento de gases de escape comprenden un catalizador de oxidación generador de amoniaco e hidrocarburos, un catalizador de TVVC y un catalizador de reducción catalítico selectivo de amoniaco (SCR) corriente abajo del catalizador de TWC. El catalizador de oxidación generador de amoniaco e hidrocarburos comprende un soporte de óxido de metal refractario, un componente de platino y un componente de paladio. El catalizador de oxidación generador de amoniaco e hidrocarburos esta sustancialmente libre de ceria y sustancialmente libre de componentes de almacenamiento de NOR. Los componentes de platino y paladio están presentes en una relación de platino a paladio de más de aproximadamente 1 a 1.
