Abstract

La presente invención se refiere a mejoras en un procedimiento para eliminar hollín depositado en un filtro de gas de escape de un motor de combustón interna, particularmente un motor Diesel, añadiendo aditivos para disminuir la temperatura de inflamación de la capa de hollín durante el funcionamiento del motor de combustión interna, CARACTERIZADAS por el hecho de que la inflamación de hollín se provoca mediante la adición de al menos un agente oxidante y/o se lleva una pluralidad de partículas de al menos un material combustible al estado incandescente o de combustión, siendo dichas partículas arrastradas por el gas de escape y depositadas sobre el filtro.
