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.
