摘要： An exhaust gas purification system for an engineering machine is capable of avoiding decreases in working efficiency during regeneration control by burning off a deposit of particulate matter from a filter efficiently during a work pause time. An operating section 17 of a display monitor 16 is used to set a work pause time and a work pause switch 13 notifies a vehicle body control unit 21 that the hydraulic excavator has entered a work pause state. In response, the vehicle body control unit 21 calculates the time required for a regenerating device to burn off the current amount of particulate matter deposited on the filter, and when the calculated time is longer than the preset work pause time, a regeneration controller 4a of an engine control unit 4 is activated, and a solenoid control valve 15 is switched to a closed position during the preset work pause time.

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： An engine control system includes pressure sensors (73, 74), position sensors (75, 76), pressure sensors (77, 78), a target revolution speed modification value computing unit (90), and a modification value adder (70r). A target revolution speed NR2 for use in control is computed based on changes of status variables such that the target revolution speed NR2 increases from the target revolution speed NR1 applied from an input unit (71), and then moderately returns to the target revolution speed NR1. In accordance with the computed target revolution speed NR2 for use in control, a target fuel injection amount FN1 is computed and a fuel injection amount is controlled. As a result, a drop of an engine revolution speed attributable to an abrupt increase of an engine load can be suppressed without sacrificing the work efficiency, and lowering of durability caused by an excessive increase of the engine revolution speed can be prevented.

摘要： A urea water tank (23) is arranged in a cab (10) at which an operator boards, thereby making it possible to arrange urea water under a preferred temperature environment for preventing freeze and crystallization of the urea water. A water supply port (24A) is provided to be opened to a left surface portion (19C) of a cab box (19) constituting the cab (10) for supplying the urea water to the urea water tank (23) from an outside of the cab (10). Therefore, even in a case of resupplying the urea water to the urea water tank (23), an operator can easily resupply the urea water through a water supply hose (24) to the urea water tank (23) from the outside of the cab (10) without entering into the cab (10).

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： A ureal water tank (28), a storage of an aqueous urea solution, is located within a utility room (6G) in a right front section of a revolving frame (6), which is readily accessible from outside. In this instance, among a plurality of operating oil conduits (18), a working mechanism operating conduit (21) which supplies operating oil to a boom cylinder (5D) of a working mechanism (5) is arranged to run along exterior surfaces of the ureal water tank (28). Therefore, even if the ureal water tank (28) is located in a place with no heat source, the aqueous urea solution in the ureal water tank (28) can be stably kept in a heated state by utilization of heat of operating oil in circulation through the working mechanism operating conduit (21).
