A filter regenerating apparatus for an internal combustion engine.

摘要

An apparatus for regenerating a filter (10) provided to scavenge particulate which is included in exhaust gas discharged from an internal combustion engine (7). The apparatus includes a heating room (9) accommodating the filter (10), a heat-combusting device for heat-combusting the particulate scavenged by the filter (10), a microwave generating device (12) for generating a microwave to be supplied to the heating room, a slit (13) provided in a wall of the heating room (9), a microwave detecting device (14) for detecting the energy level of the microwave coupled through the slit (13), and a control section (15) for controlling the heat-combusting device.
