    摘要: Disclosed is a method for preventing fuel freezing in a postprocessing burner system with a burner 14 upstream of a particulate filter 12 (exhaust purification member) incorporated in an exhaust pipe. Fuel is fed from a fuel tank 16 served also for a diesel engine 1 (engine) to the burner 14 through a feed pipe 17, and excess fuel is returned to the fuel tank 16 through a return pipe 18. The fuel is periodically circulated between the burner 14 and the fuel tank 16 through the feed and return pipes 17 and 18 under a condition of ambient air temperature during vehicle travel being at or below a predetermined temperature.

    摘要: Disclosed is a combustion/temperature increase control method for an after-treatment burner system with a burner 14 arranged upstream of a particulate filter 12 (exhaust gas purification member) incorporated in an exhaust pipe 11 to increase a temperature of the exhaust gas purification member by combustion with the burner 14. For temperature increase of the particulate filter 12 to a target temperature through ignition of the burner 14, fuel injection control of the burner 14 is effected such that a temperature increase rate of the particulate filter 12 is kept relatively high till approaching to a target temperature and is lowered stepwise after approaching to the target temperature.

    摘要: Provided is a method for performing maintenance of a particulate which can reliably remove combustion residue by means of backwash air without use of hot water and the like while cutting equipment expenses, so that substantial increase in exhaust pressure and deterioration of fuel economy during operation can be prevented.When maintenance of the particulate filter 4 is to be performed, a filler 13 is filled to each of passages 8 with outlets unplugged with plugs 9 so as to reduce an inner volume of the passage 8, and then backwash air 12 is blown into the passages 8 with the unplugged outlets.
