Abstract

Marmitta per l'abbattimento dei composti inquinanti nei gas di scarico di un motore a combustione interna, la quale comprende almeno una camera di combustione relativamente lunga, un bruciatore posto in testa alla o a ciascuna camera di combustione ed atto a creare e mantenere una fiamma pressurizzata sviluppante una temperatura relativamente elevata lungo la o la rispettiva camera di combustione, una camera di espansione ed inversione di flusso posta a valle della o della rispettiva camera di combustione, un collettore di gas di scarico da depurare disposto a ridosso della o della rispettiva camera di espansione ed in comunicazione con il sistema di scarico del motore a combustione interna, almeno un condotto di convogliamento dei gas di scarico da depurare, il quale è disposto in rapporto di scambio termico e si stende lungo ed attorno sia alla camera di espansione che alla camera di combustione a partire dal collettore fino ad almeno un primo scarico laterale in corrispondenza della camera di combustione per sottoporre i gas di scarico a surriscaldamento ed un processo di postcombustione, almeno una camicia termicamente isolante attorno sia al o a ciascun condotto di convogliamento e sia alla od alla rispettiva camera di combustione per delimitare con essa almeno un'intercapedine attraverso la quale defluiscono a ritroso i gas di combustione prevenienti dalla camera di espansione ed inversione prima di giungere ad un secondo scarico, ed almeno un gruppo di raffreddamento all'uscita di ciascuno scarico.
