Abstract
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 (S) since it has started (S), the time when a term (T) for reserving judgment as to the demand for accelerated regeneration has elapsed is taken as the judging time (T). At this judging time (T), if the assumed value of the PM deposed amount exceeds a value (J) 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 (S) sending the message to demand the accelerated regeneration.
