Abstract

DISPOSITIVO DESTINADO A MEJORAR EL FUNCIONAMIENTO DE UN CATALIZADOR (3) COLOCADO SOBRE LA TUBULADURA DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA, ESTANDO CONSTITUIDA DICHA TUBULADURA DE ESCAPE POR UN TUBO QUE DESEMBOCA POR UN LADO HACIA EL COLECTOR (1) DE LOS GASES DE COMBUSTION PROCEDENTES DEL O DE LOS CILINDROS Y QUE CUBRE POR SU OTRO EXTREMO DICHO CATALIZADOR (3). SEGUN LA INVENCION, EL DISPOSITIVO COMPRENDE AL MENOS UN TUBO (8) INTERNO DENTRO DE DICHA TUBULADURA (2), Y TIENE UN PRIMER EXTREMO (81) QUE DESEMBOCA CERCA DE DICHO CATALIZADOR (3), Y UN MEDIO (10) DESTINADO A OBTURAR SELECTIVAMENTE EL VOLUMEN INTERTUBO (9) DELIMITADO ENTRE DICHO TUBO INTERNO (8) Y DICHO TUBO (2) EN FUNCION DE LA TEMPERATURA DE LOS GASES DE ESCAPE QUE LLEGAN SOBRE DICHO CATALIZADOR (3).
