Definitions

  • the invention relates to an internal combustion engine with an intake manifold at least partially made of plastic.
  • Such intake manifold arrangements are increasingly used in internal combustion engines, a throttle valve connector being provided in the area of the intake manifold, in which a throttle valve controls the flow of the air quantity.
  • the throttle valve is operated by an electric motor, to which current is supplied for excitation by a control device in accordance with certain parameters, so that the electric motor adjusts the throttle valve in accordance with the specifications.
  • the object of the invention is to propose a simple way of dissipating the electrostatic charges.
  • the charges that form are discharged via at least one electrically sufficiently conductive connection, this electrically conductive connection being connected to the connection of the electric motor.
  • the electrostatic charges can be countered effectively in a very simple and cost-effective manner while avoiding additional weight.
  • the two leads to the electric motor are each connected to the outer wall of the throttle valve connector in order to halve the resulting voltage potential, so that any high-frequency interference due to the antenna effect can be avoided.
  • the reference numeral 10 schematically indicates a suction pipe, which can consist of plastic.
  • a throttle valve connector 12 Connected to the intake manifold area 10 is a throttle valve connector 12, which is mounted in an electrically insulated manner with respect to the intake manifold, the housing wall of which is usually made of metal.
  • a throttle valve 14 In the throttle valve connector 12, a throttle valve 14 is mounted, which can be rotated with the aid of an axis 16 and thus releases or closes the passage of the intake manifold 10.
  • An electric motor 18 actuates the axis 16 of the throttle valve 14.
  • the electric motor 18 is supplied with current with two connections 20 and 22, the control of the electric motor 18 is indicated schematically with a control device 24, this control device is a conventional part of an electronic throttle valve control or an idle charge control and does not form part of the invention.
  • An electrical connection 30 and 26 is between the wall of the throttle valve connector 12 and the feed lines 20, 22 to the electric motor 18 provided, the two connections each connecting one connection of the electric motor 18 to the throttle valve wall 12.
  • Two resistors 28 and 32 which are provided in the electrical connection 26 and 30 between the throttle valve connector 12 and the electric motor connections 20, 22, ensure that the excitation current for the electric motor 18 is not short-circuited.
  • the resistors 28 and 32 are accordingly designed with high resistance.
  • Electrostatic charges that form in the area of the intake manifold can be conducted via the electrical connections 26 and 30 to the electric motor connections 20, 22 and can therefore flow off in a low-resistance manner via the output stage. It is particularly advantageous that in the control unit 24, with which the electric motor 18 is controlled, spark extinguishing systems are provided in the output stages in order to reduce inductive voltage peaks of the electric motor; these spark extinguishing systems are simultaneously effective in order to destroy the electrostatic voltage peaks.
