Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent freezing of a feed pipe and a return pipe which connect a burner with a fuel tank even when traveling under a condition where an ambient temperature of the burner is low.SOLUTION: In a method for warming an after-treatment burner system, a burner 14 is provided upstream from a particulate filter 12 (exhaust purifying material) intermediately installed in an exhaust pipe 11 so as to heat the particulate filter 12 by burning of the burner 14. Under a condition that the ambient temperature of the burner 14 drops to or below a prescribed temperature, an electric current is passed to an electromagnetic valve-type injector 15 for spraying fuel into the burner 14 in a state of fuel supply stoppage, and the electric current passed to an electromagnetic coil inside the injector 15 produces Joule heat and warms the system.
