Definitions

  • the invention has for its object to provide an adjusting device for the start of delivery in a common camshaft for gas exchange valves and injection pump elements, which is mechanically simple and at the same time enables the injection pump elements to be arranged at any positions via the axial extension of the camshaft.
  • the cam for actuating the injection pump element on the camshaft is fixed against rotation and the delivery start adjuster rotates the entire camshaft relative to the drive shaft, a simple mechanical structure of the overall device is achieved.
  • the cams for actuating the injection pump elements are advantageously manufactured and machined in one operation with the gas exchange cams.
  • the position of the cams for actuating the injection pump elements can take place at almost any position via the axial extension of the camshaft, and thus demands regarding mechanical and dynamic properties of the camshaft as well as the arrangement of the injection pump elements to the assigned injection valves can be easily realized.
  • the delivery start adjuster is advantageously integrated into the drive gear of the camshaft. No special requirements are placed on the funding start adjuster, so that a commercial start-of-demand adjuster can be used. This can work on a mechanical, hydraulic or electrical basis.
  • the cams for actuating the gas exchange valves and the injection pump element are arranged to each other and matched to the adjustment characteristics of the delivery start adjuster that approximately at a medium speed between the idle speed and the nominal speed of the internal combustion engine, the optimally regulated delivery start over the entire speed range with the best value the gas exchange tax times coincide.
  • the camshaft 1 of an internal combustion engine is driven by a drive gear 2 from the crankshaft of the internal combustion engine at half the crankshaft speed.
  • a delivery start adjuster 2a is integrated into the drive gear 2.
  • the delivery start adjuster 2a rotates the camshaft 1 relative to the ring gear of the drive gear 2 and thus compared to the drive shaft depending on the speed of the internal combustion engine by 4 ° camshaft.
  • the camshaft 1 is supported over its axial extent in bearing points 3a to 3c.
  • Two cams 4, 4a, 5, 5a are provided per cylinder unit for actuating the gas exchange valves.
  • Tappets 6, which actuate the gas exchange valves of the internal combustion engine slide on the outer circumference of the cams 4, 4a, 5, 5a.
  • a third cam 7, 7a is assigned to each cylinder unit of the internal combustion engine on the camshaft 1.
  • a tappet 8 of an injection pump element 9 slides on the outer circumference of each cam 7, 7a.
  • Each of the injection pump elements 9 is supplied in a manner not shown with fuel which is supplied to the associated injection nozzle via the injection line 10, which is shown in part, during the pumping process of an injection pump element 9.
  • the adjustment range of the camshaft is plotted against the speed of the internal combustion engine.
  • the adjustment range is determined by the required adjustment angle of the injection cam 7, 7a (left side of the diagram).
  • the corresponding assignment of the control times for the gas exchange valves of the internal combustion engine is entered on the right-hand side of the diagram. From the diagram it can be seen that the optimal control time is at about half the speed between the idling speed n v and the nominal speed n nominal and corresponds to the speed at which the maximum torque n MDmx is present.
