<p>A method for warming an after-treatment burner system configured in a manner such that a burner (14) is provided upstream from a particulate filter (12) (exhaust purifying material) installed in an exhaust pipe (11) and combustion by the burner (14) heats the particulate filter (12), wherein under a condition when the ambient temperature of the burner drops to or below a prescribed temperature, an electric current is transmitted, in a state of fuel supply stoppage, to an electromagnetic valve-type injector (15) for injecting fuel into the burner (14), and the transmission of the electric current to an electromagnetic coil inside the injector (15) produces Joule heat and warms the system.</p> |
