Definitions

  • the invention relates to a control device for controlling the power output of an internal combustion engine for motor vehicles, in particular for combine harvesters, with a fuel pump which can be controlled via the control device as a function of at least the speed of the internal combustion engine and the setting of the carburetor as disturbance variables which are fed to a control element as a function of the position of a manually operable switch for switching a work organ on and off, a feedback signal for detecting the position of an actuator being compared to a setpoint value and a difference-equal-zero signal being triggered when the feedback signal is adjusted to the setpoint value .
  • a regulating device for regulating an internal combustion engine is already generally known (US Pat. No. 3,911,883) and is equipped with an electronic control device for regulating the fuel supply to the internal combustion engine.
  • the electronic control device is controlled depending on the engine speed, the position of the accelerator pedal and the fuel flow rate, so that the internal combustion engine is always supplied with sufficient fuel so that the power output of the internal combustion engine can be adapted to the working conditions accordingly.
  • a regulating device for regulating the output of an internal combustion engine is also known (GB-A-2 071 880), which is equipped with a regulating rod which can be controlled via a regulating device and which regulates the opening degree of a throttle valve as a function of various disturbance variables, for example the engine speed or the driving speed controls.
  • a manually operated switch for switching an air conditioning system on and off is also operatively connected to the control circuit.
  • the control device increases the power output of the internal combustion engine as a function of the power consumption of the air conditioning system with the switch in the appropriate position. If, for example, the air conditioning system is switched on, the reference voltage at the associated comparators is increased by a fixed amount.
  • the setpoint value of the engine speed is increased by the power consumption of the air conditioning system and thus the power output of the internal combustion engine is adapted to the increased power requirement with regard to the air conditioning system.
  • this requires a very complex electronic circuit.
  • the invention has for its object to control the internal combustion engine using a simply designed control device such that the motor vehicle is driven consistently when an additional unit is switched on or off.
  • This object is achieved by the features listed in the characterizing part of claim 1.
  • the advantageous design and arrangement of the control device and the corresponding decrease in the controlled variable on the working elements, in particular on the emptying device of the combine harvester ensures that when the emptying device is switched on or off, the internal combustion engine adapts to the different performance conditions, so that the combine harvester always works with the same speed can be driven, for example, to eliminate crop losses.
  • the uniform drive of the combine harvester ensures that even with an attached loader wagon, crop cannot slide out of the loader wagon, since this is always pulled by the combine harvester at a constant speed.
  • This arrangement also ensures that even with different types of crop and the associated different loads for the threshing and separating devices of the combine harvester, a sufficient power output for driving the individual working elements is ensured, so that the combine harvester always moves forward smoothly.
  • This device also ensures that, for example, a traveling loading vehicle for picking up the crop can easily drive at the same speed as the combine, since there is no sudden change in the drive of the combine.
  • a hydraulically actuatable coupling establishes a drive connection between the internal combustion engine driving a combine harvester and the working element designed as a crop emptying device and can be acted upon via the control valve which can be actuated electrically depending on the position of the switch. It is also advantageous that the fuel pump of the control device has a rack and pinion drive, which controls the fuel supply to the internal combustion engine.
  • the control loop ensures that the individual disturbance variables are recorded at the point which is responsible for a possible reduction in performance when the individual work organs are switched on, and these disturbance variables are made available as a manipulated variable for adjusting the fuel pump, so that the fuel pump is always set directly as a function of the power consumption of various working elements so that the internal combustion engine provides sufficient power.
  • the combine can be driven at a constant speed and the corresponding engine power can be made available to the individual working elements.
  • FIG. 10 an embodiment of a power amplifier device for a combine harvester according to the invention is shown schematically.
  • 10 denotes an internal combustion engine of a combine harvester (not shown in the drawing for the sake of simplicity), which is used to drive the impellers (not shown in the drawing) and the other working elements, for example an emptying device 12.
  • the internal combustion engine 10 can be actuated hydraulically Coupling 14 and a drive device 16 with the emptying device 12 drive-connected.
  • the hydraulically actuated clutch 14 can be engaged or disengaged via a solenoid-controlled control valve 18.
  • the internal combustion engine 10 is supplied with fuel via a rack-controlled fuel pump 20 and thus at a controllable flow rate.
  • the fuel pump 20 is controlled via a magnetically controlled actuator 22, which has a feedback actuator.
  • the fuel pump 20 and the actuator 22 can be designed as a structural unit.
  • a control device 21 contains an electronic control element 24, from which a control variable emerges, which results from the speed of the internal combustion engine and from the throttle position.
  • the speed of the internal combustion engine 10 is detected by a sensor 26 and the position of the gas lever by a potentiometer (not shown), which record the corresponding disturbance variables, which are then fed to the control element 24.
  • a switch 28 is connected between a summing device 30 and the electromagnetic control valve 18 and thus supplies a controlled variable to the control valve 18 in the closed position of the switch 28.
  • the summing device 30 generates an output signal which results from the sum of the signals from the switch 28 and the Control element 24 is composed.
  • a subtraction device 32 generates a controlled variable which represents a difference between the output signal from the summing device 30 and the feedback signal from the actuator 22.
  • the control circuit 21 operates in a conventional manner and controls the speed of the internal combustion engine 10.
  • the internal combustion engine 10 is set to a value so that the internal combustion engine does not output more power than for the current one Operating state for driving the individual units is necessary.
  • the control of the internal combustion engine 10 takes place as a function of the speed of the internal combustion engine.
  • the switch 28 is closed in order to switch on the emptying device 12, the size or the amount of the controlled variable is immediately changed upward, so that the internal combustion engine 10 is supplied with fuel at a higher flow rate, in order to increase the output power of the internal combustion engine increase. This prevents the driving speed of the combine from being reduced when the emptying device 12 is switched on while the combine is traveling.
  • the power booster device described can also be used in other agricultural, mobile devices which are driven by a motor or an internal combustion engine in order to always have the necessary driving force for driving all connected working tools when a further working tool is connected.
