With filter regeneration being started by determination of particulate accumulation and with an idling or light-load operation being conducted, load request to a work unit is outputted from an engine controller to a unit controller. Then, when load application is not possible or a load application cancelation switch is on and, in addition, exhaust temperature is not maintainable with no load application, a regeneration stop signal is outputted from the unit controller to the engine controller (step S7) and a regeneration stop signal reception process is conducted in the engine controller (step S8), and with no forced load application to a hydraulic unit (step S9), fuel addition is stopped to stop automatic regeneration control (step S10). |
