Abstract
Il dispositivo, determina un rilevante e, in taluni casi, totale abbattimento dell'ossido di azoto, dell'ossido di carbonio e delle particelle dei gas incombusti dello scarico che, prima dell'uscita dalla marmitta, vengono fatti passare tra due elettrodi 2 mantenuti ad alta differenza di potenziale elettrostatica, mediante un generatore di Van De Graaf 3 o simile, in modo tale da deviare gli ioni 5-6 presenti e/o indotti, su appositi raccoglitori 4, sostituibili o rigenerabili dopo determinati tempi di funzionamento.
