Definitions

  • the invention is based on a method according to the generic preamble of the main claim and further relates to internal combustion engines, injection pumps and devices for performing the method according to the invention.
  • Plug-in pumps Single-cylinder plug-in fuel injection pumps, called plug-in pumps for short, are always used advantageously when engines with low cylinder output (approx. 2 to 30 kW / cyl.)
  • the effort for an in-line or distributor injection pump is too great and when using short pressure lines and the associated use achievable better injection conditions, the injection pumps should be mounted as close as possible to the injection nozzle of the associated engine cylinder.
  • Plug-in pumps do not have their own drive, but are driven by an engine's own camshaft.
  • the control of the injection quantity takes place via a motor-specific control rod, which, like the delivery quantity adjustment element of the plug-in pump, lies below the associated mounting flange within the pump fitting of the internal combustion engine.
  • AT-PS 269 560 and DE-PS 1 050 604 have each proposed a method and associated injection pump, based on a test base pump elements set with regard to their delivery quantity and designed as plug-in pumps are combined in a common pump housing and are driven by a control rod located in the pump housing.
  • the individual pump elements can be exchanged, but the control rod, which is the same for all pump elements, must have adjustable mating coupling parts for the coupling parts of the delivery rate adjustment elements, the associated adjusting devices are very complex and costly, and the entire arrangement can be difficult to use for installation on the motor.
  • the invention has the purpose of simplifying the method for mounting the plug-in pumps and the associated pumps and the internal combustion engine in such a way that not only the method becomes cheaper, but also the plug-in pumps and the control parts on the internal combustion engine.
  • the method according to the invention with the method steps specified in the characterizing part of the main claim makes it possible, for the first time, to ensure equal delivery in multi-cylinder internal combustion engines on all injection pumps, even if the desired delivery rate is guaranteed by the injection pump manufacturer.
  • the engine-specific control rod can be designed as a simple sheet metal stamped part with fixed counter-coupling parts for the coupling parts of the delivery rate adjustment elements of the plug-in pumps, and the internal combustion engine also no longer requires a viewing window to readjust the control rod. Also to set the required engine power, the engine no longer needs to be put on the brakes, which is particularly advantageous for an integrated drive, since e.g. B. with a fixed on the engine crankshaft unit there is no possibility to adjust the engine alone with regard to its performance.
  • the fixing pin serving as the second adjusting half according to claim 3 can either by means of the dummy pump serving as a drilling device or according to the characterizing features of claim 4 by means of a a spray gun insertable plastic hot melt be attached to the pump fitting of the internal combustion engine.
  • B. is the middle position of the delivery rate adjustment element
  • the full load position of the engine's control rod set in method step h is selected according to claim 7 at the same time as a test position for setting the target delivery rate on the test bench. This would largely eliminate all tolerances on the engine and the injection pump in the most important full-load position with regard to the tolerance.
  • An injection pump designed according to claim 10 for carrying out the method defined in claim 2 or 8 differs from previously customary injection pumps only in the machined surface on the mounting flange which receives the crack mark, and in that specified by the expanded preamble of claim 12 and by the characterizing part of this claim , easy to manufacture features can with an appropriate tolerance adjustment of the individual parts of the pump an additional setting device, for. B. an adjustment eccentric on the pump element, for the equalization of the delivery rate, so that the pump can be manufactured much cheaper.
  • the same advantages also apply to a plug-in pump equipped with the features of claim 13.
  • a multi-cylinder internal combustion engine can be manufactured much cheaper than before when using the method according to claim 1, since the engine's control rod does not have to have any adjustable mating coupling parts required to equalize the delivery rate.
  • the recess provided for the engagement of a control rod blocking device can of course also be accommodated in the control linkage coupled to the control rod.
  • the control rod is also simpler than previously customary, or at least adjustable connecting pieces to the associated controller can be omitted or simplified.
  • test base to be used in the method according to the invention advantageously guarantee that the plug-in pump can be attached to the motor in a repeatable and precisely defined manner, which guarantees the desired delivery rate.
  • the dummy pump designed according to the characterizing features of claims 20 and 21 for carrying out the method step e only needs in a few quantities, for. B. to be available only once with each motor manufacturer, is cheap to manufacture and can also be formed by a plug-in pump provided with the delivery setting blocked in the basic test position, or each of the plug-in pumps to be fitted can, if a blocking device is present, serve as a dummy pump for attaching the necessary crack mark on Engine can be used.

  • the mounting flange 15 is further provided with a machined surface 18 lying on its outer circumference, which receives a tear mark 19 applied in the method described further below.
  • the plug-in pump 11 also receives in its pump housing 14 a roller tappet 21 which slides in this housing and which transmits the driving force of a drive cam 22 of the internal combustion engine to the pump piston 23. In a longitudinal groove 24 (see also FIG.

  • the value for ⁇ RW can be found on the test sheet of the associated plug-in pump 11 and is dependent on the engine power.
  • a crack mark 48 of an adjustment arrangement 49 serving as a second adjustment aid is attached, which, when the plug-in pump 11 is correctly installed, is exactly aligned with the tear marks 19 on the fastening flange 15 of the insertion pumps 11 serving as the first adjustment aid of the adjustment arrangement 49.
