Definitions

  • the present invention relates to the general technical field of injection engines of all kinds, for vehicles and in particular diesel engines.
  • the present invention relates more particularly to the control of the power delivered by such engines and more precisely the control of the injection pressure and / or the pressure of a turbocharger.
  • control method according to the invention consists in implementing its steps at a frequency of between 6 Hz and 10 Hz and preferably equal to 8 Hz.
  • the control method according to the invention consists for example in determining for the operating phase, a duration D2 of between 10 seconds and 40 seconds and preferably equal to 30 seconds.
  • the additional computer CA is also arranged via additional connection means between the original computer CO and the injectors.
  • additional connection means between the original computer CO and the injectors.
  • step c) the sensor 6 transmits the measured value Vm to the additional computer CA.
  • step g corresponding to a first phase of operation, is then implemented according to step g) up to a time t1, over a duration D1 equal to t1-t0, during which a pressure difference P2 -P1 is kept substantially constant over at least part of the duration D1.
  • step h) the control method according to the invention then consists in gradually restoring the injection pressure P1 during a second operating phase up to a time t2, over a duration D2 equal to at t2-t1.
  • the duration D1 is between 20 seconds and 40 seconds and preferably equal to 30 seconds.
  • Vc (t) converges to Vm and is advantageously a linear function.
  • Vc (t) is a step function with a step of about 0.03 volts to go from one step to the next.
  • the continuity of this temporal function Vc (t) or the relatively small pitch, thus makes it possible to implement the modification of the performance of the vehicle insensitively for the driver.
  • the aforementioned steps are completed by additional steps s1) to s5) as illustrated in FIG. figure 6 .
  • Another advantage of the control device according to the invention lies in the fact that the adaptation interfaces to the different series vehicles exist.
  • control method according to the invention lies in the choice of durations D1 and D2 corresponding to operating phases.
  • the measurement of the power delivered by an engine in the context of the European directives is carried out after a stabilization of the power level over a minimum duration of approximately one minute and the determination of a cumulation of the durations D1 and D2 less than this minimum duration does not allow to detect an increase in power for the vehicle equipped with the device according to the invention.
