摘要： 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 (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) is communicated upstream of a diesel-particulate-filter (2). The flammable gas (7) flowed 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).

摘要： The present invention has an object to provide an exhaust-gas processing device for a diesel engine, able to inhibit the deterioration of the fuel-consumption and the output reduction.In order to accomplish the above object, the device is provided with a DPF, a means for presuming the amount of PM to be deposited on the DPF, a DPF-regeneration means, a DPF-regeneration control means, a storing means, a means for sending message to demand an accelerated regeneration, and an operation means for starting the accelerated regeneration. While a normal regeneration processing is being continued (S6) since it has started (S2), the time when a term (T1) for reserving judgment as to the demand for accelerated regeneration has elapsed is taken as the judging time (T3). At this judging time (T3), if the assumed value of the PM deposed amount exceeds a value (J2) for judgment as to the demand for accelerated regeneration, the accelerated regeneration is deemed to be demanded. Then the DPF-regeneration control means allows the means for sending message to demand the accelerated regeneration to start (S8) sending the message to demand the accelerated regeneration.

摘要： An object of the present invention is to provide the exhaust treatment device of a diesel engine which is capable of prohibiting the execution of DPF regenerating processing in a situation in which the DPF regenerating processing is inappropriate.In order to achieve the object, DPF regenerating mode switch manipulation means 7a switches a DPF regenerating mode to a normal and acceleration coexistence regenerating mode 51 or an acceleration-sole regenerating mode 52, and DPF regenerating selection manipulation means 7b switches a position to a normal regenerating permission position 53, a normal regenerating cancel position 54, or an acceleration regenerating execution position 55. When the DPF regenerating mode is in the acceleration-sole regenerating mode 52, the DPF regenerating control means prohibits normal regenerating processing by the DPF regenerating means irrespective of a position selected by the DPF regenerating selection manipulation means 7b.
