Working machine

摘要

In a backhoe comprising: a diesel engine able to increase a speed due to an accelerating operation; an exhaust gas cleaning device having a DPF for catching a particulate matter included in an exhaust gas exhausted from the diesel engine; and a filter regeneration means to combust and remove the particulate matter deposited in the DPF of the exhaust gas cleaning device, the filter regeneration means requires to increase the speed of the diesel engine during an automatic regeneration for automatically combusting and removing the particulate matter deposited in the DPF. In this manner, a working machine able to require an operator to increase the speed of the diesel engine at appropriate timing, in order to increase a temperature of the exhaust gas to a temperature required for regeneration of the DPF can be provided.

主权项

1. A working machine comprising:
a diesel engine configured to increase a speed by an accelerating operation; an exhaust gas cleaning device having a filter for catching a particulate matter included in an exhaust gas exhausted from the diesel engine; a display device configured to display information related to the working machine; and a control unit configured to:
control operation of the diesel engine to combust and remove the particulate matter deposited in the filter of the exhaust gas cleaning device and configured to obtain a deposition amount of the particulate matter deposited in the filter of the exhaust gas cleaning device,perform an automatic regeneration for automatically increasing a temperature of the exhaust gas when the deposition amount obtained by the control unit is equal to or more than a second deposition amount preliminarily determined, thereby automatically combusting and removing the particulate matter deposited in the filter; andmake the display device display a warning when the deposition amount obtained by the control unit is equal to or more than a first deposition amount during the automatic regeneration, the first deposition amount being preliminarily determined and larger than the second deposition amount, the warning requesting the accelerating operation for increasing the speed of the diesel engine.
