A diesel engine (100) configured in such a manner that the diesel engine (100) can be optionally set either to a low fuel consumption mode in which the amount of fuel consumption is reduced or to a low noise mode in which the noise is reduced, that a continuous regeneration mode is automatically selected when the output value (P1) of the diesel engine (100) is greater than a predetermined value (Ptr) and, at the same time, when the estimated amount (V1) of accumulation of particulate matter collected in a DPF (22) is greater than or equal to a predetermined value (Vtr), that a forced regeneration mode is automatically selected when the output value (P1) of the diesel engine (100) is less than the predetermined value (Ptr) and, at the same time, when the estimated amount (V1) of accumulation of particulate matter collected in the DPF (22) is greater than the predetermined value (Vtr), and that, when either the continuous regeneration mode or the forced regeneration mode is manually selected, control is started depending on the selected mode.
