Definitions

  • the invention relates to a method for managing an internal combustion engine for a motor vehicle and more particularly the engines having a common rail of pressurized fuel.
  • a method of this type is for example described in WO01 / 63122.
  • the object of the present invention is to overcome all or part of the drawbacks mentioned above by proposing a method for restarting an internal combustion engine more quickly.
  • the invention is made in the context of the so-called "stop and go” technique.
  • This technique continuously controls the stopping and starting of the internal combustion engine.
  • the engine is stopped when the vehicle stops (or when it is below a threshold speed) and is restarted when the driver disengages and a speed is engaged.
  • the restart can be realized using a conventional starter or a reversible alternator.
  • a conventional start is made in substantially 1.75 turns of crankshaft. For a restart in "stop and go", it must be below 1 turn for it to be easily accepted by the occupants.
  • the glow plugs usually used during cold weather starting, will be used according to the invention to compensate for the low compression in the cylinders by a supply of calories. This is achieved by controlling the glow plugs so as to provide the necessary residual energy, in addition to that provided by the partial compression of the cylinders, for self-ignition is achieved. This saves speed of restart because it reduces the number of crankshaft needed.
  • the glow plugs are piloted between stopping and restarting the engine by a "stop and start” system associated with the powertrain. This control is performed from the engine temperature which determines the amount of heat to be brought into the cylinders.
  • the heat in the cylinders is maintained rather than giving heat just before restarting.
  • the glow plugs can be actuated non-continuously as for example with a signal of the slot type which periodically actuates said candles. This is especially important if the engine stop is extended.
  • it can be envisaged to maintain a lower temperature than the optimal autoignition temperature and then when the restart is engaged to provide a current of higher intensity.
  • the performance of the glow plugs is obviously dependent on the characteristics of the electrical network of the motor vehicle in which is installed the powertrain. Thus, it will be all the easier to start with the help of glow plugs that the edge power is strong.
  • the system "stop and start” includes a device for identifying the phase of the engine, preferably only the candles present in the cylinders in the compression phase at the time of stopping the engine will be controlled. Indeed, it is primarily in these cylinders where the energy must be sufficient.
  • the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art.
  • the glow plugs are controlled according to the compression ratio in the cylinders.
  • the spark plug control signal can be different as especially continuous just before restarting the engine.

Claims (4)

  1. Verfahren zur Steuerung einer Brennkraftmaschine, die Glühstiftkerzen aufweist, die verwendet werden während die Motortemperatur zu niedrig ist sowie ein "Stop-and-Start"-System, das dazu vorgesehen ist, den Motor anzuhalten während das Fahrzeug sich unterhalb einer Schwellengeschwindigkeit bewegt und auf ein Startsignal des Fahrers, den Motor erneut zu starten, dadurch gekennzeichnet, dass die Glühstiftkerzen während eines erneuten Startvorgangs ebenfalls aktiviert werden wenn der Motor aufgrund eines Steuersignals des Anhaltesystems ausgeschaltet ist, um den Zylindern des Motors Kalorien zuzuführen, um die Selbstentzündung zu erleichtern und somit ein erneutes Starten zu beschleunigen.
  2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass das Aktivieren der Glühstiftkerzen nur in den Zylindern des Motors erfolgt, die während des Stillstands des Motors aufgrund der Steuerung des Anhaltesystems in einer Kompressionsphase sind, um die Beschleunigung des erneuten Startens zu optimieren.
  3. Verfahren nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass das Aktivieren der Glühstiftkerzen diskontinuierlich erfolgt um notwendige Energie zu sparen.
  4. Verfahren nach Anspruch 3" dadurch gekennzeichnet, dass das Aktivierungssignal der Glühstiftkerzen die Form eines Pulszuges hat.
