Abstract:
To perform filter regeneration processing while avoiding the exhaustion of unburnt exhaust gas.
An exhaust temperature elevation apparatus 140 includes a burner device 200, a temperature detector 204 and a burner controller 206. The burner device 200 is disposed on a prestage of a diesel oxidization catalyst 130 that oxidizes exhaust gas, in an exhaust route 110 of a diesel engine 100 and burns fuel. The temperature detector 204 detects the temperature of the exhaust gas prior to flowing into the diesel oxidization catalyst. When the detected temperature of the exhaust gas exceeds a predetermined value, the burner controller 206 brings the burner device into an active state.
