Definitions

  • the invention relates to a method for producing an idling fuel mixture, intended to be delivered into an intake manifold of an internal combustion engine; it extends to an idle jet designed to be mounted on an auxiliary idle carburetor with a view to implementing the method of the invention.
  • the present invention proposes to remedy the shortcomings of known idling jets.
  • An objective of the invention is in particular to indicate an improved process for producing the idling fuel mixture, making it possible to ensure excellent homogeneity of this mixture. Another objective of the invention is thus to allow significant savings in fuel consumption, in particular when driving in built-up areas.
  • Another objective of the invention is to allow a gradual transition from idle speed to speeds
