摘要： The pump controller determines pump load torques (T r1 , T r2 ) from tilting signals (θ 1 , θ 2 ) of hydraulic pumps(1,2) and delivery pressure signals (P D1 , P D2 ) of the hydraulic pumps (1,2) based on T r1 = K · θ 1 · P D1 and T r2 = K · θ 2 · P D2 (K: constant), and adds these pump load torques to provide a resulting value as an engine load torque signal (T). Using the signal (T) and an engine revolution speed signal, an engine controller determines a fuel injecting rate to control a pre-stroke actuator. Simultaneously, the engine controller calculates target injection timing not to change fuel injection start timing, thereby controlling a timer actuator. This makes it possible to control the fuel injection rate with good response and high accuracy following load fluctuation, achieve improved combustion, and hold a fuel injection period within an optimum angle range. As a result, optimum combustion is achieved and such a deterioration of exhaust gas as the generation of NO x and black smoke can be avoided.

摘要： When a changeover switch (45) is turned to a "front side" position, upstream portions of pilot lines are connected to boom-up/down lines, arm dumping/crowding lines, and bucket crowding/dumping lines, respectively, causing pilot pressures to control valves for driving hydraulic actuators of a work front (5). When the changeover switch is turned to a "blade side" position, the upstream portions of the pilot lines are connected to blade-up/down lines, blade left/right-angling lines, and blade right/left-rising tilt pilot lines, respectively, causing pilot pressures to control valves for driving hydraulic actuators of a blade (3). The blade can be operated in various behaviors without narrowing a space in a cab and deteriorating operability of the blade.

摘要： A reference pump-delivery-rate calculating portion (70a) calculates a reference delivery rate (QR10) of a hydraulic pump (1) by referring to a table stored in a memory based on a control pilot pressure (PL1) for the hydraulic pump. A target pump-delivery-rate calculating portion (70c) divides the reference delivery rate (QR10) by a ratio (NRC/NR1) of a maximum revolution speed NRC to a target engine revolution speed (NR1), thereby calculating a target delivery rate (QR11). A target pump tilting calculating portions (70e) divides the target delivery rate (QR11) by an actual engine revolution speed (NE1) and a constant (K1), thereby calculating a target tilting (θR1). A solenoid output current calculating portion (70g) calculates a drive current (S11) to provide the target tilting (θR1) and outputs the drive current (S11) to a solenoid control valve (30). The pump delivery rate is thereby controlled with good response following input change of operation instructing means.

摘要： In the arm-crowding or track operation, a calculating portion (700d2 or 700d4) calculates a modification gain (KAC or KTR) depending on an operation pilot pressure and a calculating portion (700g) calculates a decrease modification (DND) based on the KAC or KTR, while a calculating portion (700m or 700p) calculates a modification gain (KACH or KTRH) depending on an operation pilot pressure and calculating portions (700q - 700s) calculate an increase modification (DNH) based on the KACH or KTRH. A reference target engine revolution speed NR0 is modified using the DND and DNH. In other operations than the arm-crowding and track operations, NR0 is modified using only the decrease modification (DND) calculated from the modification gain just depending on the operation pilot pressure. In the operation where an engine revolution speed is desired to become higher as an actuator load increases, the engine revolution speed can be controlled in accordance with change of the actuator load as well. In other operations, the engine revolution speed can be controlled just depending on the direction and input amount in and by which corresponding operation instructing means is operated.
摘要翻译：在臂拥挤或轨道运行中，计算部分（700d2或700d4）根据操作先导压力计算修正增益（KAC或KTR），并且计算部分（700g）基于KAC计算减小修正（DND）或KTR，而计算部分（700m或700p）根据操作先导压力计算修正增益（KACH或KTRH），并且计算部分（700q-700s）基于KACH或KTRH计算增加修改（DNH）。使用DND和DNH修改参考目标发动机转速NR0。除了斗杆拥挤和轨道运行以外的其他操作中，仅根据操作先导压力，仅使用根据修正增益计算的减少修正值（DND）修改NR0。在期望发动机转速随着致动器负载增加而变高的操作中，也可以根据致动器负载的变化来控制发动机转速。在其他操作中，发动机转速可以仅根据操作相应操作指令装置的方向和输入量来控制。
