Abstract
An exhaust emission purifier for a diesel engine has a particulate trap disposed in the exhaust emission passage of the diesel engine for entrapping particulates contained in exhaust gases emitted from the diesel engine, the particulate trap being housed in a canning container. An electric heater is disposed in the canning container upstream of the particulate trap for heating the exhaust gases to a temperature which is high enough to burn particulates entrapped by the particulate trap. A heat conductor/converter device disposed in the canning container upstream of the electric heater for absorbing heat radiated from the electric heater and discharging the absorbed heat into air flowing from a position upstream of the canning container into the particulate trap. The heat generated by the electric heater is efficiently utilized to heat the air introduced into the particulate trap for reliably and quickly igniting and burning the entrapped particulates.
