Definitions

  • the invention relates to a control device of the type specified in the preamble of the first claim.
  • Such a device is known from DE-OS 32 10 903. It is used to adjust the control rod stop depending on various operating parameters, which are continuously recorded by an electrical control device, for example control electronics and compared with predetermined values, in order to have the optimum performance of the internal combustion engine available, but without it to overload or endanger. Among other things, it is possible to increase the service life of the internal combustion engine.
  • the R egelelektronik can detect many operating parameters and specify a currently optimum value of the control rod stop.
  • DE-OS 32 10 903 describes a control rod stop controlled by control electronics, which is not completely dependent on the control electronics, but which, for example, is still mechanically influenced by the boost pressure of a supercharged internal combustion engine. This is disadvantageous, since the electrical setpoint for the control rod stop, which the control electronics specifies, does not necessarily lead to a specific, explicit manipulated variable of the control rod stop. If the control electronics are to take into account all influences and operating parameters of the internal combustion engine, the control device disclosed in DE-OS 32 10 903 requires a feedback of the actual mechanical manipulated variable.
  • the object of the present invention is to improve the control device of the generic type in such a way that the control rod stop follows an electrical setpoint, which is predetermined by control electronics, in a simple manner without further dependence.
  • the mechanical control value of the control rod stop should be proportional to the electrical setpoint and free of feedback.
  • control electronics which detects all operating parameters of the internal combustion engine by means of suitable sensors and processes them to a setpoint for the control rod stop, is a necessary prerequisite for the particularly advantageous use of a control rod stop according to the invention, which is intended to replace a control rod stop of a known type. Since the control impulses of the control electronics are directly converted by the new control rod stop in a size corresponding to the setpoint of a control element limiting the control rod path, there are no additional components that may be required. It is possible to use the control electronics in a simple manner to control the control rod stop using new operating parameters which have not previously been taken into account or which have only been partially taken into account.
  • the invention uses electrical energy only to control a rotary valve.
  • the force required to adjust the control rod stop is taken from a pressure medium. Since the rotary valve is rotated axially, it has practically no movement-inhibiting forces to overcome. Small electrical energies thus advantageously control large mechanical forces. According to the invention, this control takes place without feedback with the pressure control circuit integrated in the inclined edge control.
  • the rotary position of the rotary valve in connection with the inclined edge determines the target size of the pressure force, and thus also the position of the control rod stop.
  • Fig. 1 shows a section through an inventive R egelstangenanschlag.
  • the membrane 4 is firmly clamped between an upper housing part 5 and a lower housing part 13.
  • a sleeve 3 is also fixedly connected to this.
  • the rotary valve 2 guided by it, which can be rotated in small steps by the stepping motor 1, which is fixedly mounted in the upper part of the housing 5.
  • the upper edge of the sleeve 3 is provided with a bevel 9.
  • the control rod 12 which is guided axially in the lower housing part 13, is firmly connected to the sleeve 3.
  • the lower housing part 13 is arranged on an injection pump housing such that the control rod 12 already protrudes into the injection pump.
  • the position of the control rod 12 defines the stop 18 for the control rod 17 via the angle lever 16.
  • a spring 11 presses the membrane 4 and thus the sleeve 3 together with the control rod 12 in the unloaded state to the upper maximum value, ie the opening 8 is closed.
  • the fluid passes through inlet 6 via the throttle bore 7 into the pressure chamber above the diaphragm 4 and leaves it via the opening 8, the gap 10 and the drain bore 14.
  • the throttle cross section of the throttle bore 7 is smaller than the flow cross section of the opening 8.
  • the control electronics determine a specific position of the control rod stop depending on the operating parameters. Then the rotary valve 2, again controlled by the stepping motor 1, assumes a certain angular position. If the drain opening 8 is now blocked by the sleeve 3, a pressure begins, i. H. also a force to build up on the membrane 4, which presses it down, ie also the sleeve 3. This continues until the inclined edge 9 meets the drain hole 8. The position of the inclined edge 9, which partially covers the bore 8, regulates itself automatically so that the inflow and outflow of the pressure medium remain in balance. The height position of the membrane 4 is thus virtually fixed. For each rotary position of the rotary valve 2, therefore, an exact position of the inclined edge 9 belongs, with which the control rod 12 is also fixed. This type of control is clear and does not require feedback of the controlled variable.
