ABSTRACT:
An exhaust passage extends from an internal combustion engine to conduct exhaust from the engine. A filter is disposed in the exhaust passage to filter particles out of the exhaust. A burner is disposed in the exhaust passage upstream of the filter to burn off the particles deposited on the filter. Fuel is supplied to the burner for a preset time when the filter clogs. The supplied fuel is ignited in the burner. In the case where the fuel supplied to the burner ceases to burn prior to the end of the preset time, the fuel supply to the burner is interrupted.
