Definitions

  • the invention relates to a mechanical injection pump controller with an atmospheric and boost pressure-dependent adjustment device for an air-compressing internal combustion engine according to the features specified in the preamble of the claim.
  • Such an injection pump regulator is known from DE-OS 37 36 781, in which a quantity correction element of the adjustment device acts via a pivot body designed as a link body on a deflection lever guided with it in the link, and has a quantity-correcting effect.
  • an intermediate lever connected to the adjustment lever is also guided in the backdrop, via which the deflection lever, the control lever and finally the quantity adjustment element are adjusted when a load is input.
  • a change in boost pressure always causes a change in the injection quantity and also an undesirable change in torque in the part-load range of the internal combustion engine, although the driver does not change the position of the accelerator pedal.
  • the invention is therefore based on the object of averting these deficiencies by simple measures in the injection pump controller.
  • the load is input from an adjusting lever 3 connected to the accelerator pedal (not shown) via an intermediate lever as a transmission element 4 and a deflection lever 5 on a control lever 6 and via a tab 7 on the quantity adjusting element 8 designed as a control rod.
  • the transmission member 4 is operatively connected to a swivel body 9 as part of the adjustment device 2, which has the shape of an angle lever, the upwardly projecting leg 9a of which is articulated on a quantity correction member 10 of the adjustment device and the laterally extending leg 9b is rotatably mounted on a bearing pin 11 , which in turn is clamped on the controller housing 1a (FIG. 2) in a rotationally fixed manner.
  • the swivel body 9, which can be rotated counterclockwise when the boost pressure increases, is provided on the underside of its leg 9b with a slideway 12, which also applies to certain ones Boost pressure conditions serves as a counter-stop for a stop 13 on the transmission member 4.
  • This stop 13 is designed as a stop pin and lies approximately in the longitudinal center of the angled transmission member 4, one end of which has a bearing pin 4a which is guided in a link 5a of the guide lever 5, and the other end of which is connected in a rotationally fixed manner to an adjusting lever shaft 14.
  • an overpressure member 15 with a compensating spring 16 is arranged, which yields as soon as the transmission member strikes the swivel body 9 when the accelerator pedal is depressed.
  • the injection quantity in the part-load range is influenced only as a function of the load, but not as a function of the charge pressure, and also only in the case when the accelerator pedal causes an excess is requested at which the limit lambda ( ⁇ 1.2 ⁇ ) falls below the current boost pressure.
  • the adjustment lever angle of 50 ° corresponds to the full load stop position of the accelerator pedal. If the driver now depresses the accelerator pedal up to an adjustment lever angle of 35 °, which corresponds to a control path of approx. 9 mm, and if the boost pressure is then effective up to a value of approx. 1200 mbar, the control path only changes when the Driver using the accelerator pedal to request a surplus.
