ABSTRACT:
A method and device for removing soot from the exhaust gases of a diesel-type internal combustion engine, using a soot filter in the exhaust line and a dosing device which injects a dose of a combustion-inducing substance, for example CuCl, into the soot filter by means of compressed air. The soot-combusting process is initiated automatically, in response to a critical exhaust pressure level and the simultaneous presence of a suitable temperature in the soot filter, using a pressure switch and a series-connected thermal switch. Compressed air, flowing through a bypass line, scavenges the supply line of the combustion-inducing substance, while supplying additional oxygen for the soot combustion process.
