ABSTRACT:
A smoke filter element adapted to remove solid particles from an internal combustion engine's exhaust gas stream includes a bed which forms a multi-passage path along which the carbon particles are retained. A heating system incorporated into the filter periodically heats the flowing exhaust stream, as well as the bed. Rejuvenation of the bed by burning off carbon is automatically prompted when filter pressure and temperature reach predetermined levels. Concurrently the engine throttle is adjusted to a preferred engine speed whereby ideal conditions for burning are established.
