摘要： This invention provides a traveling system for an engineering machine, adapted to limit a maximum traveling speed of the machine without causing decreases in engineering work efficiency or in accelerating performance during a start of traveling, and to improve fuel efficiency by suppressing a loss of engine output horsepower under the limited state of the maximum traveling speed. During fourth-gear shift control process, capacities of first and second hydraulic motors 23, 24 are controlled in coordinative form and the second hydraulic motor 24 has its minimum tilting amount limited to a tilting amount limit q2cmin. In addition, when a tilting amount of the first hydraulic motor 23 reaches a minimum tilting amount q1min, the engine 10 has its maximum engine speed limited to a first engine speed limit Ncmax1 (e.g., 1,800 rpm).

摘要： A hydraulic steering unit 5 generates a control pressure corresponding to the rotational quantity and rotational direction of the steering wheel 109 on the basis of pressurized oil of a pilot pump 13. Signals of pressure sensors 6a and 6b used to detect the control pressure, and a signal of a front operation detection unit 31, are inputted into a controller 132. A controller 32 and solenoid valves 33a and 33b control a stroke of a steering valve 4 so that the stroke becomes larger with increase in control pressure detected by each of the pressure sensors 6a and 6b. In addition when the operation of a front work device is detected, the controller 32 and the solenoid valves 33a and 33b control the stroke of the steering valve 4 so that the stroke becomes larger than that provided when the operation of the front work device is not detected.

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.

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： A modification torque ΔT and a torque converter speed ratio e is computed from input and output revolution speeds of a torque converter 31. A first determination coefficient α corresponding to the speed ratio e, and a second determination coefficient β corresponding to a pump pressure are computed. A selector 87 selects the smaller one of these coefficients as a determination coefficient γ, and the modification torque ΔT is multiplied by γ to provide a modification torque ΔTA. An adder 89 adds the modification torque ΔTA (negative value) to a pump base torque TR to provide a modified pump base torque TRA, whereby a maximum pump absorption torque TRA is controlled so as to become TRA. The maximum pump torque reducing control can then be performed while accurately confirming a work situation during the combined operation of travel and a working actuator.
