Title:

EXHAUST EMISSION CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JP2002180818

Kind Code:

A

Abstract:

To effectively use filter scavenging capacity.

A heater element HE is provided along the outer periphery in an exhaust gas introducing part of a filter 30. The heater element HE is connected to a heater element control circuit 61 via an electric power supply line, and the heater element control circuit 61 carries an electric current to the heater element HE according to a command from an engine ECU 60. The heater element HE is heated when receiving the electric current, and burns a suspended particle-like substance accumulated in the exhaust gas introducing part of the filter 30. As a result, the suspended particle-like substance accumulated in the exhaust gas introducing part of the filter 30 is removed, and scavenging performance of the filter 30 is recovered.
