Definitions

  • the present invention relates to a method for determining a game between two moving parts as known according to US-A-5,832,955 .
  • the method of the invention is more particularly usable in heat engines having valves each associated with a valve actuator to determine the clearance between the tail of each valve and the movable member of the actuator which cooperates with the tail of the valve. the valve for moving the valve between an open position in which the valve is spaced from its seat and a closed position in which the valve is pressed against its seat.
  • electromagnetic valve actuators which conventionally comprise elastic means and electromagnetic means for actuating the movable member between two extreme positions respectively corresponding to the open position of the valve and to the closed position of the valve.
  • the elastic means generally comprise a spring associated with the movable member to bias the latter resiliently in its extreme open position and a spring associated with the valve stem to resiliently bias the latter in its closed position and to bias elastically the movable member in its extreme closed position.
  • the electromagnetic means generally comprise an electromagnet supplying and / or holding the movable member in the extreme open position and an electromagnet for supplying and / or holding the movable member in the extreme closed position.
  • the movable member and the valve are not connected to each other and there is a game commonly called “distribution clearance" between the movable member and the valve when the movable member is in the extreme closed position and the valve is correctly pressed against its seat by the spring associated therewith.
  • the distribution clearance varies during operation of the engine, in particular as a function of temperature, and also during the life of the engine, in particular according to the wear of the valve and the various components of the actuator. valve.
  • the distribution clearance may vary from one actuator to another depending on the manufacturing tolerances thereof.
  • An object of the invention is to provide a means for a simple and accurate way of determining the distribution set.
  • the invention is here described in application to the actuation of a valve 1 of a heat engine with the general reference 2.
  • the valve 1 has a shank 3 and is mounted on a cylinder head 4 of the engine 2 to slide between a closed position in which the valve is applied against a seat 5 of the cylinder head 4 and an open position in which the valve is detached from the seat 5 of the cylinder head 4.
  • the valve is actuated between these two positions via an actuator generally designated 6 mounted on the cylinder head 4 of the heat engine 2.
  • the actuator comprises a body 7 in which is mounted to slide a movable member generally designated 8 having a rod 9 having a first end 10 arranged to bear on a free end of the tail 3 of the valve 1 and a second end 11 secured to a pallet 12 received in a housing 13 of the body 7 to slide parallel to the rod 9.
  • the body 7 incorporates, in a manner known per se, electromagnetic means for moving the movable member 8.
  • the electromagnetic means comprise an electromagnet 14 for holding the vane 12 in a position called the extreme closing position of the valve and an electromagnet 15 for holding the vane 12 in a position called the extreme open position of the valve which open on two opposite sides of the housing 13 of the body 7.
  • the pallet 12 is here in contact with the electromagnet 14, 15 when it is in the corresponding extreme position.
  • the electromagnets 14, 15 are controlled in a manner known per se by non-represented means of servocontrol from a setpoint current and a moving speed of the movable member 8. This servo mode is known in itself. This slaving can be ensured by the engine control unit which also operates a speed signal of the pallet 12 obtained by derivation of a position signal provided by a position sensor 16 of the rod 9.
  • the position sensor 16 is for example a Hall effect sensor known in itself.
  • the actuator also comprises, in a manner known per se, elastic displacement means.
  • the elastic displacement means comprise in a known manner in itself a spring 17 interposed between a face 18 of the body 7 and a shoulder 19 of the rod 9 to recall the pallet 12 in the extreme open position and a spring 20 interposed between a face 21 of the yoke 4 and a shoulder 22 of the valve stem 3 to return the valve 1 in the closed position.
  • the actuator, the cylinder head 4 and the valve 1 are arranged in such a way that, when the pallet 12 is in the extreme closed position and the valve 1 is applied against its seat 5, there is a clearance j or set of distribution between the first end 10 of the rod 9 and the free end of the valve stem 3.
  • the method according to the invention makes it possible to determine the clearance j during the operation of the heat engine.
  • the method according to the invention comprises the step of controlling the electromagnets 14, 15 to move with a substantially constant speed the movable member 8 from its extreme closed position to its extreme open position.
  • the speed of movement of the movable member can be kept constant until the extreme open position or over a distance greater than a maximum possible clearance given the geometric characteristics of the actuator, the valve and the cylinder head.
  • the method comprises the step of obtaining values of the target current for intermediate positions of the movable member during the displacement of the movable member 8 from the extreme closed position to the extreme open position and the step of detecting an intermediate position of the movable member 8 for which the setpoint current undergoes a sudden change.
  • the setpoint current is supplied by the servo-control means (but it could be measured or detected) and the intermediate positions of the movable member 8 are provided by the position sensor 16.
  • the setpoint current is then related to the intermediate positions of the movable member 8.
  • the detection of the intermediate position for which the setpoint current undergoes a sudden change is preferably made from the derivative of the reference current relative to the position of the pallet 12.
  • this derivative is shaped as a curve, the curve has peaks at the intermediate position corresponding to the meeting point of the movable member 8 and the valve stem 3.
  • the electromagnetic means can be controlled to first bring the movable member 8 gently to the intermediate position determined herein. above to bring the movable member 8 into contact with the valve stem 3, then accelerate the movable member 8 once it bears against the valve stem.
  • the electromagnetic means can be controlled to first bring the movable member 8 quickly to the intermediate position determined above to have a quick closing of the valve, then gently bring the movable member 8 in extreme closed position to limit the noise of the contact of the pallet 12 with the electromagnet 14.
  • the determination of the game j is preferably renewed periodically, for example every second.
  • the clearance j can be determined with different modes of operation depending on the engine operating mode and the engine speed.
  • the implementation of the method described above does not interfere with the normal operation of the actuator, it does not generate additional noise and is therefore particularly suitable for use at idle speeds.
  • a determination method that would cause more noisy operation of the actuator could be used when the engine is in start mode or the engine is in normal operating mode at a higher speed than a predetermined speed, for example 2000 rpm .
  • the method of the invention can be realized for a displacement of the movable member towards the extreme open position as described above or towards the extreme closed position.
  • the moving speed of the movable member will be kept substantially constant, for example from a median intermediate position of the pallet.
  • the electromagnetic means can be controlled from another electrical characteristic such as a set voltage.
