Abstract
The present invention has an object to provide an exhaust device for a diesel engine capable of surely burning flammable gas in an exhaust route. In the exhaust device for the diesel engine, liquid fuel () is supplied from a liquid-fuel supply source () to a gas generator (). The gas generator () converts the liquid fuel () to flammable gas () and has a flammable-gas flow outlet () of the with which an exhaust route () is communicated upstream of a diesel-particulate-filter (). The flammable gas () flowed out from the flammable-gas flow outlet () is burnt with oxygen in exhaust gas () to produce combustion heat. The exhaust gas () heated by the thus produced combustion heat can burn the exhaust-gas fine particles remaining at the filter (). The gas generator () is provided with a catalyst chamber () which houses a catalyst (). Catalyst-combustion heat is generated in the catalyst chamber () which is arranged along an external periphery of a peripheral wall () of the exhaust route ().
