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).

摘要： An engine powered machine is provided with an economical exhaust gas purification system capable of avoiding overheating. The engine powered machine is provided with an exhaust gas purification system that injects a reducing agent into an exhaust pipe of an engine by a reducing agent feeder to detoxify nitrogen oxides in exhaust gases. A cooling fan, the driving or stopping of which is controlled by a controller, is arranged as a cooling device for a reducing agent tank in which the reducing agent to be injected by the reducing agent feeder is stored. When a detected temperature signal output from a reducing agent temperature detector has become higher than a cooling initiation temperature stored in a storage unit, the controller drives the cooling fan to initiate cooling of the reducing agent tank.

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： An engine powered machine is provided with a high-performance exhaust gas purification system and is capable of promptly raising a temperature of an operator's cab to a comfortable temperature. The exhaust gas purification system that makes use of an NOx removal catalyst and a reducing agent is provided with a reducing agent heater for heating a reducing agent, which is stored in a reducing agent tank, with heat of an engine cooling medium and an on/off device for controlling an introduction of the engine cooling medium into the reducing agent heater. When a temperature of the engine cooling medium is higher than a first predetermined temperature, a temperature of the reducing agent in the tank is lower than a second predetermined temperature and a temperature in an operator's cab is lower than a third predetermined temperature, a controller switches the on/off device into a dosed state to increase a flow rate of the engine cooling medium to be guided to a heat exchanger of a heating apparatus.
