METHOD FOR WARMING AFTER-TREATMENT BURNER SYSTEM

Disclosed is a method for warming an after-treatment system in which a burner 14 is arranged upstream of a particulate filter 12 (exhaust purifying member) incorporated in an exhaust pipe 11 and the particulate filter 12 is adapted to be heated by combustion with the burner 14. On condition that an...

Zusammenfassung:	Disclosed is a method for warming an after-treatment system in which a burner 14 is arranged upstream of a particulate filter 12 (exhaust purifying member) incorporated in an exhaust pipe 11 and the particulate filter 12 is adapted to be heated by combustion with the burner 14. On condition that an ambient temperature surrounding the burner 14 is below a predetermined temperature, the energization is conducted to an electromagnetic valve-type injector 15 serving for fuel spray of the burner 14 with the fuel supply being stopped. The energization brings about Joule heat generated in an electromagnetic coil inside the injector 15 to make the warming.
