Definitions

  • the invention relates to a method for managing a internal combustion engine for a motor vehicle and more particularly engines with a common rail pressurized fuel.
  • the purpose of the present invention is to mitigate all or disadvantages mentioned above by proposing a process to restart a motor faster internal combustion.
  • the invention is made in the context of the so-called “Stop and go”. This technique allows for continual check the stopping and starting of the combustion engine internal.
  • the engine is stopped when the vehicle comes to rest (or when it is below speed threshold) and is restarted when the driver disengages and that a speed is engaged.
  • the restart can be realized using a conventional starter or alternator reversible.
  • a typical start is made in substantially 1.75 turns of crankshaft. For a restart in "stop and go", it is necessary to be below 1 turn for it is easily accepted by the occupants.
  • crankshaft turn number when one is substantially under 0.7 turn, it is very difficult to achieve self-ignition of the air-fuel mixture in the cylinder when starting because the compression in the cylinder can no longer bring enough energy.
  • the glow plugs will serve according to the invention to compensate for the low compression in cylinders by a contribution of calories. This is done in piloting the glow plugs so as to provide the residual energy required, in addition to that provided by the partial compression of the cylinders, so that the auto-ignition to become true. This helps to speed up reboot as this allows to decrease the number of turn of crankshaft needed.
  • the piloting of candles preheating is carried out between stopping and restarting the engine by a "stop and go" system associated with the group power train.
  • This piloting is carried out from the engine temperature that determines the amount of heat to bring into the cylinders.
  • the heat in the cylinders is maintained rather than giving heat just before restart.
  • the glow plugs can be operated so non continuous like for example with a signal of type to crenels which periodically actuates said candles. it is particularly important if the engine stop is extended.
  • the performance of the glow plugs is good obviously dependent on the characteristics of the network of the motor vehicle in which is installed the powertrain. Thus, it will be all the easier to start using the glow plugs that the edge electrical power is strong.
  • the system "stop and start” includes a device identification of the engine phase, preferentially only the candles present in the cylinders in phase of compression at the time of engine shutdown will be piloted. Indeed, it is primarily in these cylinders where the energy must be sufficient.
  • the present invention is not limited to illustrated example but is susceptible of various variants and modifications that will occur to those skilled in the art.
  • the piloting of the glow plugs is realized depending on the compression ratio in the cylinders.
  • the piloting signal of the candles can be different like especially continuous just before restart of the motor.
