    • PURPOSE: An engine RPM(Revolution Per Minute) control system for a working vehicle is provided to prevent the output RPM of an engine from increasing by operation of an input device in the state positioning an accelerator lever in an idling position. CONSTITUTION: An engine RPM(Revolution Per Minute) control system for a working vehicle is composed of a pedal sensor(32), a foot accelerator control unit, a lever sensor(34), a hand accelerator control unit, and a forward rotation control unit. The foot accelerator control unit controls a foot accelerator which has the engine RPM corresponding to the output of the pedal sensor as the target RPM. The hand accelerator control unit controls a hand accelerator which has the engine RPM corresponding to the output of the lever sensor as the target RPM. The forward rotation control unit controls so that the RPM memorized in a memory device is as the target RPM. If the RPM corresponding to the output of the lever sensor is higher than the idling RPM, the forward rotation control is processed through operation of input devices(37,38). If the RPM corresponding to the output of the lever sensor is less than the idling RPM, the forward rotation control is stopped through operation of the input devices.

    • PURPOSE: An engine control apparatus for a work vehicle is provided to operate a fuel injection control unit based on the torque curve characteristic that engine rpm changes according to the change of torque. CONSTITUTION: An engine control apparatus for a work vehicle comprises first and second mode controllers(81,82), a control mode managing unit(94), a differential computing unit(95), and first and second engine load estimating units(81a,82a). The first and second mode controllers execute first and second mode control for determining the fuel injection amount of an engine based on first and second torque-engine rpm characteristics. The control mode managing unit selects the first or the second mode control. The differential computing unit calculates the difference between the unloaded engine rpm corresponding to an operating position detected by an operating position sensor(75) and the engine rpm detected by an rpm sensor(72). The first and second engine load estimating units estimate the engine load based on the rpm in the first mode control and on the fuel injection amount in the second mode control.

    • PURPOSE: An engine revolution set structure for work vehicles is provided to enable the change of revolution per minute memorized in a memory device and facilitate the simplification of an operation structure. CONSTITUTION: An engine revolution set structure for work vehicles comprises artificial manipulation type order devices(37,38), and a control device. The artificial manipulation type order device orders the read of 'the revolution per minute of an engine memorized in a memory device(21D). The control device performs the control of the forward rotation which controls output RPM, so the RPM memorized in the memory device is obtained as the output RPM of the engine based on the manipulation of the order device. The control device changes the set point of the RPM of the engine memorized in the memory device in case of different manipulation with the manipulation of the order device.

    • PURPOSE: An engine RPM(Revolution Per Minute) control system for a working vehicle is provided to control the output RPM so that the engine RPM memorized in a memory device is obtained as the output RPM of an engine through the operation of a command unit. CONSTITUTION: An engine RPM(Revolution Per Minute) control system for a working vehicle is composed of a manually controlled command unit(37,38) and a control unit(36). The manually controlled command unit commands the read of the engine RPM memorized in a memory device(21D). The control unit executes the forward rotation control. The forward rotation control controls the output RPM so that the engine RPM memorized in a memory device is obtained as the output RPM of an engine through the operation of the command unit. If the operation different from the operation of the command unit is executed, memory RPM change control changing the setting of the engine RPM memorized in the memory device through the different operation is executed.
