摘要： During an operation, a control device (38) for performing output control of an engine (10) determines whether or not the engine (10) and/or an exhaust gas purifying device (18) has a malfunction. If it is determined that the engine (10) and/or the exhaust gas purifying device (18) has a malfunction, a highest rotational speed of the engine (10) is controlled to a second rotational speed (Nt) higher by a predetermined amount (α) than a first rotational speed (Ns) at which an engine maximum torque (Tm) before the malfunction can be outputted. In this case, a maximum fuel injection quantity of the engine (10) is limited so that a rated torque (Tr) before the malfunction can be outputted at the first rotational speed (Ns).

摘要： In a work machine, a communication system is provided, in which, when damage of disconnection or the like of a communication line occurs, desired communication is enabled without requiring manual replacement of the damaged communication line. The communication system is provided in a hydraulic excavator and comprises a vehicle body controller 12 and a monitor controller 13, serving as a first controller coupled to each of a drive-system communication line 10 and an information-system communication line 11. The communication system also comprises an engine controller 14, serving as a second controller coupled to either one of the communication lines 10 and 11. When a damaged part A develops at a portion of a drive-system communication line 10 located between the vehicle body controller 12 and the engine controller 14 and communication between the vehicle body controller 12 and the engine controller 14 becomes impracticable, the communication between the vehicle body controller 12 and the engine controller 14 is made practicable, by detouring the communication through the information and communication line 11 which has not suffered the damage, and through the monitor controller 13.
