Method of removing soot from exhaust gases

摘要

A method of removing soot from the exhaust gases of internal combustion engines, especially of the diesel-type, using an exhaust filter which collects the soot and a dosing device which, when triggered by a pressure switch and a series-connected temperature switch, injects a dose of a combustion-inducing substance onto the soot layer with the aid of compressed air. The combustion-inducing substance consists of CuCl and NH4NO3 which are stored as a mixture in a single container or as separate ingredients in two containers.
