Abstract
A soot reservoir for an exhaust gas scrubbing system for an internal combustion engine has a housing, having an inlet for introducing a soot-laden carrier flow diverted from the exhaust gas flow and an outlet for the escape of the scrubbed carrier flow, a soot filter disposed between the inlet and outlet for retaining soot particles, and a removable collecting container for receiving the trapped soot. To attain a large storage capacity of the collecting container, a number of compacting balls are placed loosely in it. Hopping and rolling movements of the balls caused by the motion of the vehicle driven by the engine produce a considerable increase in the settled apparent density of the soot deposited in the collecting container. With the same collecting container volume, about 10 times as much soot can be held, when compared with conventional soot reservoirs.
