    摘要: The disclosed exhaust treatment device for a diesel engine can prevent heat damage to a DPF when regenerating said DPF. If a selection device(7), which selects whether to allow or prohibit an automatic DPF regeneration process, is set to prohibit the automatic DPF regeneration process, a DPF regeneration control device(4) is made able to start a process to cancel execution of the automatic DPF regeneration process. If the selection device(7) is set to allow the automatic DPF regeneration process, the DPF regeneration control device(4) retracts the cancellation of the automatic DPF regeneration process, allowing execution of the previously-cancelled automatic DPF regeneration process to begin.

    摘要: There is provided an exhaust apparatus for a diesel engine that rapidly burns an unburned deposit in an upstream exhaust catalyst with heat of a heater.
    An exhaust apparatus for a diesel engine including a downstream exhaust cleaner 101, an upstream exhaust catalyst 102 provided in the upstream of the downstream exhaust cleaner 101 in an exhaust passage, and a heater 3 includes an engine starter apparatus 131, a control unit 4 configured to control power supply to the heater 3 and an engine start process S12 performed by the engine starter apparatus 131, and a start command unit 105 connected to the control unit 4. The heater 3 is disposed at an exhaust inlet 102a of the upstream exhaust catalyst 102, and when an engine has been stopped and then the start command unit 105 gives the control unit 4 a start command, the control unit 4 performs powering S11 of the heater 3, without performing an engine start process S12 so as to keep the engine stopped for a predetermined period of time after the start command has been given, and subsequently performs the engine start process S12.
