摘要： A hydraulic drive system for a hydraulic working machine sets a delivery pressure at a preset value upon raising a temperature of exhaust gas to a temperature needed for combustion of particulate matter by increasing a load to be applied to an engine. In a non-operation state, a variable restrictor is controlled by a controller and a delivery pressure control valve to increase a delivery pressure of a variable displacement hydraulic pump, so that the load is increased to raise the temperature of exhaust gas to the temperature needed for the particulate matter combustion. At this time, the controller controls the delivery pressure control valve such that a delivery pressure to be detected by a delivery pressure sensor will conform with a preset reference delivery pressure. The reference delivery pressure is set to a minimum pressure that can provide the exhaust gas with combustion heat.

摘要： An exhaust gas post-treatment system for a vehicle is provided, which in the course of regeneration ascertains whether or not there is any object approaching a body of the vehicle from behind. A filter is arranged in an exhaust passage of an engine to trap PM therein. A trapped and deposited PM amount sensing device senses a deposited amount of PM deposited in the filter. A fuel injector burns and removes PM deposited in the filter to conduct regeneration of the filter. A rearward monitoring camera monitors a scene rearward of a vehicle body. A display module displays monitoring information from the rearward monitoring camera, and a controller having a regeneration processing unit executes control processing to actuate the fuel injector and to perform regeneration. The controller includes a display continuation processing unit for executing control processing such that during the regeneration by the fuel injector, the monitoring information from the rearward monitoring camera is continuously displayed on a display screen of the display module.

摘要： When an output value of an exhaust resistance sensor 34 has reached or exceeded a set value ΔPa, a controller 20 executes recovery control of a filter of an exhaust gas purification device 32 after conducting exhaust temperature increasing control by operating a pump discharge pressure increasing device (solenoid proportional valve) 38 so that exhaust gas temperature as an output value of an exhaust temperature sensor 33 reaches a preset value Ta. Thus, the recovery process of the exhaust gas purification device can be executed with reliability by increasing the exhaust gas temperature irrespective of the operating environment and the fuel consumption can be kept at a minimum necessary level.

摘要： The operability when performing a combined arm-crowd and bucket operation can be improved. A hydraulic drive device for a hydraulic excavator includes: a bucket directional control valve and a second arm directional control valve, which are connected in parallel tandem with a first hydraulic pump; a first arm directional control valve that is connected to a second hydraulic pump; and a flow rate restriction device that restricts the flow rate of pressure oil supplied to the second arm directional control valve, during crowd operation of a bucket. This flow rate restriction device includes a variable throttle whose opening is controlled so as to become smaller as a bucket operating device is operated to the crowd side, the variable throttle being provided in a bypass path connecting to the supply port of the second arm directional control valve.
