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： 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 treatment filter removes particulate matter from exhaust gas of a diesel engine. The particulate matter which accumulates on the filter is removed by a manual regeneration system that can simply be controlled.After a manual regeneration switch 22 is shifted to an ON-position, a load control section 66 keeps at least one of the revolution speed N of an engine 1, the displacement volume q and discharge pressure P of a hydraulic pressure pump 11 at a corresponding first target value (N1, q1, or P1) or second target value (N2, q2, or P2) depending on a temperature of the cooling water in relation to a flame-out prevention temperature T1. A regeneration control section 67 starts the compulsory regeneration after the manual regeneration switch has been shifted to the ON-position and when the cooling water temperature is equal to or higher than T1.

摘要： An exhaust gas cleaning system for an engineering vehicle, such as a hydraulic excavator, is capable of performing manual regeneration control of a regeneration fuel injector 40 that is started only under the following conditions: a manual regeneration starting switch 39 is enabled; an engine control dial 2 commands a low-speed idle revolution speed; and a gate lock lever 22 is switched to a second position B at which generation of control pilot pressures a through f by use of remote control valves 25, 26, and 27 is disabled. Even when the manual regeneration control is being executed, if the gate lock lever 22 is switched to a first position A, the manual regeneration control immediately ends. As a result, the manual regeneration control of a filter for collecting particulate matter included in the exhaust gas and the operation of the work system do not influence each other.

摘要： Each time a starting process for a diesel engine 2 is conducted and before the diesel engine 2 is started, any differences of the pressures P1 and P2 detected by first and second pressure sensors 21 and 22, respectively, with respect to a predetermined reference pressure value Pref, are computed and stored as first and second correction values ΔP1 and ΔP2, and then a differential pressure P12 across a particulate filter in the diesel engine 2 is computed using the pressure detection results of the first and second pressure sensors 21, 22 and the first and second correction values ΔP1, ΔP2. Thus, use of simply constructed and highly durable sensors during the detection of the differential pressure existing across the filter allows accurate measurement of this differential pressure.
