Definitions

  • the present invention relates to a combustion gas supply system of a vehicle internal combustion engine, comprising, in an intake manifold, an intake throttle integral with the displacement of a shaft of a regulation motor itself integral with the movement of a mechanical control member and means for determining the displacement of the motor, relative to a position of rest, under the action of mechanical control, the mechanical control member directly controlling the movement of the motor.
  • the speed of the engine is notably determined at from the accelerator pedal, which acts on the intake throttle.
  • the engine To operate in optimal conditions, so as not to stall or not polluting excessively, the engine must be powered by a mixture of air and gasoline desired flow rate and remaining in well defined proportions.
  • a speed control computer motor controls, by a stepping motor, a circuit adjustment needle additional and prevents stalling by the corresponding air supply.
  • Document FR-A-2 599 805 teaches a feeding system of the type mentioned above, in which the motor shaft is integral in rotation with the butterfly and the stator associated 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 it is provided a microprocessor to cyclically compare the displacement of the motor to a threshold of movement of its tree and the butterfly in a given period of time and thus control the movement of the motor shaft and therefore of the throttle valve to limit the speed of movement of the shaft by controlling a complementary movement and progressive of the latter.
  • the power system shown in Figure 1 is here mounted on the motor internal combustion of a car and comprises a butterfly 1 mounted mobile, here in rotation, in an air intake manifold 2 of a carburetor not shown.
  • 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 tubing 2 and carries the housing 6 leaving it free to rotate around the tree 4.
  • the displacement sensor 8 cyclically determines the angular position of the box 6 relative to the pipe 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 has a hollow spherical cap 13 adjusted 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 ( Figure 3) of rotation angular of the shaft 4 relative to the housing 6.
  • the accelerator pedal 10 directly drives the housing 6.
  • the corresponding rotation by relative to the tubing 2 is measured by the sensor 8 and the series of signals corresponding measurement allows the microprocessor 7 to determine the amplitude and the speed of this rotation.
  • the microprocessor 7 has in memory a corresponding threshold value at a maximum admissible value DO (FIG. 3) of angular variation of the position of throttle 1 in a given time period TO, a fraction of a second, value which it compares cyclically to the measured angle of rotation of the housing 6.
  • the microprocessor 7 then controls the stepper motor 5 if the variation angular exceeds the threshold value DO in a time less than the duration TO, that is to say at a significant amplitude and excessive speed.
  • Curve 22 is always in this range P, even if it means following it temporarily an edge and not to optimally correct the deviation 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.
