Abstract

Un dispositivo de escape que comprende: un colector de escape (1) que se conecta en cada una de las lumbreras de escape (P1-P4) de un motor de combustión interna de múltiples cilindros (100) y que recoge los gases de escape de cada una de las lumbreras de escape (P1- P4); un cono del lado aguas arriba (22) de un catalizador (20) que está conectado al colector de escape (1) y purifica los gases de escape; un sensor de gases de escape (39) que se proporciona en el cono del lado de aguas arriba (22); estando el dispositivo de escape caracterizado por que: comprende una carcasa externa (34) que está superpuesta sobre un lado exterior del cono del lado de aguas arriba (22); y una cámara de sensor (36) que está formada entre el cono del lado de aguas arriba (22) y la carcasa externa (34), en donde el cono del lado de aguas arriba (22) está provisto de una salida de flujo a través de la que la cámara de sensor (36) se comunica con un interior del cono del lado de aguas arriba (22), y en donde un canal de flujo de entrada (48, 50) está formado entre el cono del lado de aguas arriba (22) y la carcasa externa (34), teniendo el canal de flujo de entrada (48, 50) una abertura (52, 54) que se abre en el interior del colector de escape (1) a fin de comunicarse con la cámara de sensor (36).
