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.
