Title:
ディーゼルエンジンの排気装置
Document Type and Number:
Japanese Patent JP4794595
Kind Code:
B2
Abstract:
In an exhaust device for a diesel engine, liquid fuel (6) is supplied from a liquid-fuel supply source (5) to a gas generator (3). The gas generator (3) converts the liquid fuel (6) to flammable gas (7) and has a flammable-gas flow outlet (9) of the with which an exhaust route (1) communicating upstream of a diesel-particulate-filter (2). The flammable gas (7) flowing out from the flammable-gas flow outlet (9) is burnt with oxygen in exhaust gas (10) to produce combustion heat. The exhaust gas (10) heated by the thus produced combustion heat can burn the exhaust-gas fine particles remaining at the filter (2). The gas generator (3) is provided with a catalyst chamber (51) which houses a catalyst (4). Catalyst-combustion heat is generated in the catalyst chamber (51) which is arranged along an external periphery of a peripheral wall (1a) of the exhaust route (1).
