Definitions

  • the invention relates to a device for contacting an engine control unit with current consumers, in particular Actuators of an electromagnetic valve control, from Internal combustion engines according to the preamble of the claim 1.
  • DE 42 25 329 A1 describes a generic device for Contacting an engine control unit with actuators electromagnetic valve control of an internal combustion engine known.
  • the internal combustion engine has a cylinder head in the gas exchange valves are arranged by the electromagnetic Actuators are operated, the cylinder head is covered by a cylinder head cover.
  • the actuators include opening and closing magnets, controlled by the engine control unit takes place.
  • each actuator has a cable based on the respective actuator within the Cylinder head cover to a recess in the cylinder head cover is routed through which the cable for connection to the engine control unit is then inserted.
  • a disadvantage of the device is that when putting it on the cylinder head cover bruises in the cylinder head cover loose cables may be possible.
  • Another disadvantage the device lies in the tightness problems, since the cylinder head cover through the recesses for the cables potential Has leaks. Otherwise, the cylinder head cover due to the cables arranged inside the cylinder head cover be dimensioned sufficiently so that all for the actuators needed cables find their place unhindered.
  • the object of the invention is a device for contacting of electricity consumers with an engine control unit Train internal combustion engine so that at the same time Optimization of installation space enables an improvement in assembly.
  • a major advantage of the device according to the invention lies in the optimization of assembly and space requirements.
  • the integration of the electrical required for contacting Components, i.e. the power stages, the recordings for the power-side connector, and the line end stages and the recordings connecting lines, in the frame part of the Cylinder head means a significant relief in the Assembly because before the cylinder head cover is placed on the Cylinder head all electricity consumers with actuators in particular the engine control unit can be connected without, for example Cables are passed through the cylinder head cover have to. Only the plugs of the power consumer-side cables in the frame-side connector receptacles inserted, the frame part itself over only a cable is connected to the engine control unit. Before putting on the cylinder head cover is now only to be checked, whether a cable is without contact or has been crimped.
  • the potential leaks are caused by the frame part avoided in the cylinder head cover when performing the cable is possible through the recesses in the cylinder head cover were, because the plug of the electricity consumers only in the Plug receptacles of the frame part must be inserted and the electricity consumers via a central, starting from the frame part Cables are connected to the engine control unit.
  • the frame part by integrating the electrical components an optimization of the installation space is achieved in the frame part.
  • The include electrical components integrated into the frame part all for contacting electricity consumers with the engine control unit necessary elements, such as power amplifiers, Connector sockets and cables for connecting power amplifiers and plug receptacles, whereby only the electricity consumer side Lines with plugs inside the valve gear compartment must be led to the connector receptacles.
  • This reduction in the number of components results in a compact arrangement the device possible.
  • FIG. 1 shows a device in a first exemplary embodiment for contacting an engine control unit, not shown here with electricity consumers a multi-cylinder Internal combustion engine, which is particularly closer below described actuators 1 of an electromagnetic valve control as well as ignition coils 2.
  • the three-cylinder internal combustion engine shown has a cylinder head 3, which consists of three housing parts 3a, 3b, the first housing part 3a being the actual cylinder head, the second housing part 3b is flanged to the cylinder head Frame part and the third housing part, not visible here forms a cylinder head cover which can be placed on the frame part 3b.
  • the cylinder head 3 there are one ignition coil 2 and four per cylinder Gas exchange valves 4 (see FIG. 2) mounted, which corresponding Control invisible gas exchange channels and one each actuator 1, which is also mounted in the cylinder head 3, the gas exchange valves 4 essentially in the area of the first housing part, i.e. of the cylinder head 3a and the Ignition coil 2 and the actuators 1 essentially in the area of the flanged frame part which forms a valve drive chamber 3b are arranged. On the frame part 3b, the third Mounted part of the cylinder head, the cylinder head cover become.
  • Each actuator 1 has a displacement sensor 5 for detecting a Position and / or movement of the gas exchange valve 4 and two electrically controlled switching magnets 6, 7, i.e. one Closing magnet 6 and an opening magnet 7, between their Pole surfaces 8, 9 an armature connected to the gas exchange valve 4 10 coaxial to the valve axis 11 (see. Fig. 2) is arranged.
  • a spring mechanism not visible here the consists of two preloaded compression springs, forms with the gas exchange valve 4 a spring-mass oscillator, its rest position between the two valve end positions, i.e. between open position and the closed position of the gas exchange valve 4.
  • valve operation is started by that the armature 10 of the closing magnet 6 or opening magnet 7th against the elastic restoring force of the spring mechanism in Direction of the associated end position is tightened. Subsequently the gas exchange valve 4 is alternately opened thereby and concluded that the current supply of the currently holding Switching magnet 6, 7 is switched off, causing the gas exchange valve 4 from the spring mechanism from the previous end position accelerated out until the rest position was reached becomes. That which moves beyond the rest position in this way Gas exchange valve 4 is then from the opposite Switching magnets 6, 7 against the elastic restoring force of the spring mechanism caught, what the switching magnet 6, 7 with a so-called capture current is applied.
  • a power output stage 12 is assigned to each cylinder, which that of four actuators 1 together with four displacement sensors 5 and one Ignition coil 2 controls existing consumer group.
  • the power amplifiers 12 along with the associated recordings for the actuator side 13, 14 and ignition coil-side connector 15 are in the frame part 3b integrated and either individually or centrally via a cable, not shown, from the frame part 3b with the engine control unit connected.
  • Travel sensor 5 To power an actuator 4 with an associated one Travel sensor 5 are seven lines, which are in two plugs 13, 14 flow, needed. Three lines 17 are used for the displacement sensor 5 required and four lines 18 are for the switching magnets 6, 7th provided, the lines 17 of the displacement sensor 5 in one Plug 13 and the lines 18 of the switching magnets 6, 7 of the actuator 1 also open into a connector 14.
  • the ignition coil 2 For power supply the ignition coil 2 is a line 19 with a plug 15 provided, the receptacle for the ignition coil side Connector 15 is also integrated into the frame part 3b.
  • the electrical components 12 ' are only partially integrated into the frame part 3b '.
  • the power amplifiers 12 ' are arranged on the frame part 3b' and only the lines connecting the power amplifiers 12 'to the Connect receptacles for the plug 14 'on the consumer side, and the recordings themselves are integrated in the frame part 3b '.
  • the cylinder head consists of only two housing parts consists of what the first housing part is the cylinder head and the further housing part forms a cylinder head cover, in which some or all of the electrical components are integrated and which are connected to the Engine control unit is connected.
  • one facing the cylinder head can be in the frame part Sealing strip and / or one facing the cylinder head cover Sealing strip be introduced.
