Title:
EXHAUST GAS PURGING DEVICE OF DIESEL ENGINE
Document Type and Number:
Japanese Patent JPS5925024
Kind Code:
A
Abstract:
PURPOSE:To perform efficient regeneration of a trap, by installing a burner, heating the trap, to the outside of an exhaust pipe to guide the combustion gas of the burner to surroundings of the trap. CONSTITUTION:A nozzle 22 sprays the fuel through a nozzle port 26 to jet it in an igniting chamber 24. The sprayed fuel is ignited by spark from an igniting electrode 28, and after it enters a gasifying chamber 42, it is fed to a mixing chamber 44. Gasification of the fuel, entering the mixing chamber 44, is further promoted, and simultaneously, the fuel is mixed with the air supplied from a blower 60. The mixture enters a combustion chamber 50, and the air necessary to combustion is supplied for combustion. The combustion gas of the fuel, which is completely turned in a burner 16 in a manner described above, is exhausted to the outside through a gas flow passage 56 installed around a trap 14. As noted above, combustion in the burner 16 can be steadily made at the outside of an exhaust pipe 12 without being influenced by a pressure within an exhaust pipe, and being exerted by an adverse influence, such as exhaust pulsation, exhaust gas chemical compound.
