Definitions
- the invention relates to an internal combustion engine with an at least partially plastic suction pipe.
- Such intake manifold arrangements are increasingly found in internal combustion engines Use, with a throttle body in the area of the intake manifold is provided in which a throttle valve the flow of air controls.
- the throttle valve is operated by an electric motor, the current parameter determined by a control unit for Excitation is supplied so that the electric motor corresponding to the throttle valve the specifications.
- the object of the invention is to provide a simple way of deriving the electrostatic Propose charges.
- the charges that form form at least one electrically sufficiently conductive connection is derived, this electrically conductive connection to the connection of the electric motor connected.
- the two Supply lines to the electric motor each with the outer wall of the throttle body are connected to the resulting voltage potential to halve so that any high-frequency interference that may occur the antenna effect can be avoided.
- a suction pipe is indicated schematically, the can consist of plastic. Includes the intake manifold area 10 throttle valve connector, electrically insulated from the intake manifold 12 on, the housing wall is usually made of metal. In the throttle valve connector 12, a throttle valve 14 is mounted, which with With the help of an axis 16 is rotatable and thus the passage of the suction pipe 10th releases or closes. 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 schematic with a control device 24 indicated, this control device is a conventional part of a electronic throttle control or an idle charge control and does not form part of the invention.
- the design of the resistors 28 and 32 is accordingly high impedance.
- Electrostatic charges can form in the area of the intake manifold via the electrical connections 26 and 30 to the electric motor connections 20, 22 are routed and can thus have a low impedance via the output stage flow away. It is particularly advantageous that in the control unit 24, with which the electric motor 18 is controlled in the final stages spark extinguishing systems are provided to inductive voltage peaks of the electric motor dismantle, these spark extinguishing systems are effective at the same time, to destroy the electrostatic voltage peaks.
