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： 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： 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 fuel tank (12) is constructed such that a front flange portion (14A1) of a top surface plate (14A) of a second plate (14) extends outside in relation to a front surface plate (13B) of a first plate (13). As a result, a front surplus space (15A) projected in the upper and lower directions in a range of the front flange portion (14A1) of the top surface plate is formed in the front surface side of the front surface plate. A urea water tank (24) is arranged along the fuel tank (12) in such a manner that a rear side portion thereof enters into the front surplus space. Therefore, the rear side portion of the urea water tank can enter into the front surplus space using the front surplus space formed in the fuel tank (12), thereby increasing the tank capacity without downsizing the article accommodating box (16).

摘要： Front and rear side flange portions of a filter accommodating cylinder are provided with positioning pins. A flange portion of an upstream cylinder is provided with a notched groove and a flange portion of a downstream cylinder is provided with a notched groove. In consequence, when the filter accommodating cylinder is connected between the upstream cylinder and the downstream cylinder, each of the positioning pins disposed at the front and rear flange portions is engaged with each notched groove of the upstream cylinder and the downstream cylinder. The filter accommodating cylinder can be positioned to be coaxial with the upstream cylinder and the downstream cylinder. As a result, after performing a cleaning operation to a DPF, an operation of once again connecting the filter accommodating cylinder between the upstream cylinder and the downstream cylinder can be quickly and easily performed.

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.
