Definitions

  • the present invention relates to a combustion gas supply system for an internal combustion engine of a vehicle comprising, in an intake manifold, an intake butterfly mounted movable in movement under the action of a mechanical control member. and integral in displacement with the shaft of a displacement control motor, the motor being integral in displacement with the control member.
  • the speed of the engine is notably determined from the accelerator pedal, which acts on the intake throttle.
  • the engine To operate in optimal conditions, in order not to stall or not to excessively pollute, the engine must be powered by a mixture of air and gasoline at the desired flow rate and remaining in well-defined proportions.
  • a motor speed control computer controls, by a stepping motor, an adjustment needle of the additional circuit and prevents stalling by the corresponding air intake.
  • Document FR-A-2 599 805 teaches a supply system of the type mentioned above, in which the motor shaft is integral in rotation with the butterfly and the associated stator is rotatably mounted and driven by an accelerator pedal .
  • the present invention aims to solve this problem.
  • the supply system of the invention is characterized in that a microprocessor is arranged to measure the displacement of the regulation motor relative to a rest position and to control the rotation of the shaft of this last according to said displacement.
  • the microprocessor is arranged to, in response to a movement of the control member, limit the speed of movement of the shaft and control, if this is the case, a complementary and progressive movement of the latter.
  • the supply system represented in FIG. 1 is here mounted on the internal combustion engine of a car and comprises a throttle valve 1 mounted mobile, here in rotation, in an air intake pipe 2 of a non-carburetor represented.
  • the butterfly 1 is integral, in rotation about an axis 3, with the shaft 4 of a motor 5, step by step in this example, housed in a housing 6 with a microprocessor 7 which controls it and with an angular displacement sensor 8.
  • the shaft 4 is respectively carried at its two ends by two bearings, not shown, integral with the tube 2 and carries the housing 6, leaving it free to rotate around the shaft 4.
  • the displacement sensor 8 cyclically determines the angular position of the housing 6 relative to the tubing 2 and transmits a signal corresponding to the microprocessor 7.
  • a cable 11 connects an accelerator pedal 10 to one end of a link 12, the other end of which comprises a hollow spherical cap 13 fitted on a spherical stud 14, eccentric with respect to the axis 3, of the housing 6.
  • a shaft 4 of the stepping motor 5 is attached a radial index 15 moving between two stops 16-17 of the housing 6 and thus limiting the range P (FIG. 3) of angular rotation of the shaft 4 relative to the housing 6.
  • the accelerator pedal 10 directly drives the housing 6 in rotation.
  • the corresponding rotation relative to the tubing 2 is measured by the sensor 8 and the series of corresponding measurement signals allows the microprocessor 7 to determine the amplitude and the speed of this rotation.
  • the microprocessor 7 has in memory a threshold value corresponding to a maximum admissible value DO (FIG. 3) of angular variation of the position of the butterfly valve 1 in a given time period TO, a fraction of a second, a value which it compares cyclically with the measured angle of rotation of the housing 6. The microprocessor 7 then controls the stepping motor 5 if the angular variation exceeds the threshold value DO in a time less than the duration TO, that is to say at an amplitude significant and excessive speed.
  • DO maximum admissible value
  • the position angular 21 of the butterfly 1 is coincident with the curve 20 as long as the angular deviation 20 of the housing 6 is less than the threshold DO.
  • this threshold is exceeded here after a duration less than the duration TO, so that the microprocessor 7 then controls the stepping motor 5 to rotate its shaft 4 in the opposite direction to that of the housing 6 (arrow F1), so that the rotation of the butterfly 1 follows a curve 22 having a lesser slope than that of the curve 20 in its variable part, until later joining the curve 20.
  • the curve 22 is always in this range P, leaves to temporarily follow an edge of it and not to optimally correct the deflection of the butterfly 1 if the correction to be made exceeds half of this range P.
  • absolute angular position sensor 8 could be replaced by a relative displacement detector, such as an accelerometer, from the measurements of which the microprocessor 7 would determine relative rotations.
