Definitions

  • the invention relates to an arrangement for increasing the idle speed of an internal combustion engine, in particular a diesel engine, with an actuator for influencing the fuel supply, the displacement of which can be limited in the idling direction by an idling stop or after a starting operation by a starting quantity stop.
  • the adjustment path can be limited by a plurality of start quantity stops arranged one after the other in the idling direction, of which the starting quantity stop which is the most distant from the idle stop can be moved out of the adjustment path of the actuator one after the other at certain time intervals.
  • This configuration of the arrangement makes it possible to easily obtain an increased idling speed after a starting process, which is gradually reduced to normal operation in accordance with the average heating curve of the internal combustion engine.
  • the actuator can be the adjusting lever of the control rod of a fuel injection pump that controls the delivery volume, e.g. a diesel internal combustion engine.
  • the starting quantity stops are ramps of different radial extension of a swivel element which can be rotated step by step, and the idle stop can also be a ramp of the swivel element, only a few mechanical components and only one drive are required for this.
  • the swivel element can be rotated through 360 °, the position is automatically taken up again after the start operation has expired, from which a new start interval can begin again directly.
  • the swivel element is a disk arranged in the plane of movement of the adjusting lever.
  • One possibility of rotating the swivel element is an electric stepper motor.
  • crank mechanism has two levers which are arranged at an angle to one another and are connected to one another in an articulated manner and is connected in the region of the connected lever ends to the pivot element eccentrically to its axis of rotation, the free lever ends being drivable approximately linearly independently of one another, so can be done in a simple manner a rotary drive of the swivel element can be achieved in four stages with two linear drives.
  • the free lever ends are preferably movable toward one another or away from one another.
  • the free lever ends can be moved by an electromagnetic actuating element.
  • the electromagnetic actuating elements can be hinged armature relays, to the hinged armature of which a free lever end is articulated.
  • the unequal restoring forces of the two hinged anchors can ensure the clear course of the actuating element in a pivoting direction.
  • the crank drive can have a link pin in the area of the interconnected lever ends, which engages in a link guide of the swivel element.
  • the drive of the crank mechanism can be controlled by electronics that have a pulse generator that can be switched on by the starting process, the output of which is connected to a counting unit, via the first output of which a first electromagnetic control element maintaining its control position for a certain time and via the second output of which a second one Activation position a certain time maintaining electromagnetic actuator can be controlled.
  • This drive can be implemented using simple series components and therefore cheaply.
  • the first actuating element can preferably be actuated by the pulse counter immediately after the starting process and for this purpose with a time delay before the actuation time of the first actuating element expires, the actuation time of which extends beyond the actuation time of the first actuating element.
  • a temperature switch is arranged in the ground connection of the electromagnetic actuating elements, which is located above a certain operating temperature of the internal combustion engine in the open position, the normal idling speed is set directly when the internal combustion engine is already warm. This is e.g. Required if the internal combustion engine was only switched off briefly after a long period of driving and is therefore still at operating temperature when it is started again. An idle speed that is too high for this operating state is thus avoided.
  • the fuel injection pump has a pivotable adjustment lever 3.
  • This adjustment lever 3 has a stop cam 4 which can be brought into abutment on a pivot element 5 which is arranged in the same plane as the adjustment lever 3 and is designed as a disk.
  • This pivot element 5 limits the pivot path of the adjusting lever 3 in the idle direction.
  • the arrangement shown in Figure 2 has the same pivot element 5 as shown in Figure 1. It consists of a 360 0 rotatable disc, the uniformly distributed on its radially encircling peripheral four ramps 6, 6 ', 6'',6''' has a different radial extension. Uz are the ramps 6 - 6 ''clockwise from the ramp 6 with the greatest radial extension decreasing successively to the ramp 6''' with the smallest radial extension.
  • crank gear For driving the Schwenkel E ments 5, a crank gear is 7, which is' operable by two hinged armature relay 8 and 8.
  • the crank mechanism 7 consists of two levers 9 and 10 which are arranged at an angle to one another and are connected at an angle to one another. At the articulation point of the levers 9 and 10, a projecting link pin 11 of the crank mechanism 7 is fastened, which protrudes into a diagonal link guide 12 of the pivot element 5.
  • the free ends of the levers 9 and 10 of the crank mechanism 7 are connected in an articulated manner to one end of the hinged armature 13 and 13 'of the hinged armature relay 8 and 8'.
  • the other ends of the hinged armature 13 and 13 'designed as a two-armed lever are connected to one another via a tension spring 14, so that the hinged armature 13 and 13' are folded away from the relay when the relay is deenergized, as is the case with the hinged armature relay 8 shown on the left.
  • the right hinged armature relay 8 1 is shown in the energized hinged armature 13 'attracting position.
  • the link pin 11 is located at point 15, which corresponds to the normal position at the operating temperature of the internal combustion engine 1.
  • the link pin 11 moves from point 15 to point 16, after a certain time sequence to point 17, again after a certain period of time according to point 18 and finally back to point 15.
  • the link pin 11 projecting into the link guide 12 moves the pivot element 5 in four 90 ° sections by a total of 360 °.
  • FIG. 3 is assigned to the hinged armature relay 8 and FIG. 3a to the hinged armature relay 8 '.
  • the switching position of relays 8 and 8 ' is plotted over time in the diagrams.
  • both hinged anchors 13 and 13 are in the position folded down from relay 8 and 8 1, respectively. If a starting process is now started, 19 pulses are fed from a pulse generator to a counting unit 20 designed as a binary counter. This counting unit 20 immediately transmits a signal to the hinged armature relay 8, which switches to its switched-on switching position, as can be seen at time T1 in diagram 3. This position is maintained for a certain time since the hinged armature relays 8 and 8 'are each temporally persistent.
  • the temperature switch 21 located in the ground connection of the relays 8 and 8 ' is closed.
  • the counting unit 20 also begins to count in order to emit a signal to the folding armature relay 8 ′ at 2 5 pulses, which then switches to its energized switching position at time T2.
  • the stopping time of the hinged armature relay 8 ' has also expired, so that the hinged armature 13' also returns to its starting position and the idle position is thus reached at normal operating temperature.
  • the temperature switch 21 which switches depending on the temperature of the internal combustion engine 1 opens, as a result of which the hinged armature relays 8 and 8 1 are no longer supplied with current and the hinged armatures 13 and 13 'drop into their starting position.
