Abstract

LA INVENCION ESTA RELACIONADA CON UNA MAQUINA MATRIZ DE COMBUSTION INTERNA DE INYECCION DE VARIOS CILINDROS QUE COMPRIME EL AIRE, CON UN CATALIZADOR DE ADSORCION DE OXIDO DE NITROGENO Y UN DISPOSITIVO DE RETORNO DE LOS GASES DE ESCAPE. CON OBJETO DE AUMENTAR EL PORCENTAJE DE HIDROCARBONO EN LOS GASES DE ESCAPE DELANTE DE UN DISPOSITIVO DE TRATAMIENTO POSTERIOR DE GASES DE ESCAPE DURANTE UNA FASE DE REGENERACION Y DE REDUCIR EL CONTENIDO DE OXIGENO, SE PROPONE QUE LOS TUBOS DE GASES DE ESCAPE DE LOS CILINDROS SE DIVIDAN EN, AL MENOS, DOS ZONAS DE ADMISION SEPARADAS ENTRE SI EN, POR LO MENOS, UN TRAYECTO, GENERANDOSE EXCLUSIVAMENTE EN LOS CILINDROS DE UNA DE LAS ZONAS DE ADMISION Y TEMPORALMENTE UNA MAYOR EMISION DE HIDROCARBURO, MIENTRAS QUE LA OTRA ZONA DE ADMISION SE UNE A TRAVES DEL DISPOSITIVO DE RETORNO DE GASES DE ESCAPE AL CONDUCTO DE ADMISION DE AIRE DE LA MAQUINA MOTRIZ DE COMBUSTION INTERNA.
