Definitions

  • the invention relates to a valve control for an internal combustion engine according to the Preamble of claim 1.
  • a known valve control of an internal combustion engine US 5,031,583, includes one Camshaft with cams of different profiles that have an intake valve or an exhaust valve actuate. Rocker arms are provided between the cams and the valves with which the stroke of the respective valve can be influenced by means of coupling elements.
  • the camshaft is provided with a phase adjuster, with which the Control times of the valves are changeable.
  • the disadvantage of this design is that none Precautions are taken to monitor the function of the coupling elements.
  • the function switching state can also generate the function signal Phase control of a camshaft, switching state of the valve lift circuit, speed of the The camshaft and oil temperature of the lubricating oil of the internal combustion engine are also used become.
  • An internal combustion engine 1 comprises a plurality of cylinders 2 and opposite ones Rows 3 and 4, in which the cylinders are provided.
  • Each row of cylinders 3 has a cylinder housing 5 and a cylinder head 6.
  • the cylinder head 6 is with each cylinder 2 provided at least one inlet valve 7 and an outlet valve 8, which are part of a Valve control 9 are and for gas exchange control in a combustion chamber 10 of the respective Serve cylinder 2.
  • the actuation of the intake valves 7 and the exhaust valves 8 will by means of an intake camshaft 11 and an exhaust camshaft 12, being between the camshafts 11 and 12 and the valves 7 and 8 bucket tappets 13,14 are arranged.
  • At least the tappets 13, which are connected to the inlet valves 7 interact, are designed as switching elements 15 with which the stroke of Inlet valves 7 is variable or switchable.
  • each inlet valve 7 on the Inlet camshaft 11 different cams 16 and 17 attached - Fig. 2 -. there causes cam 16 a maximum stroke of the inlet valve 7; Cam 17 a reduced Stroke.
  • the intake camshaft 11 is provided with a camshaft adjuster 18 provided with their relative rotational position at angle a to the exhaust camshaft 12th is changeable.
  • the timing of the intake valves 7 and the exhaust valves 8th to be influenced.
  • the change in rotational position of the intake camshaft 11 and the stroke switching of the Switching elements 15 are e.g. depending on the speed and the accelerator pedal position the internal combustion engine 1.
  • torsional vibration signals Ds of the intake camshaft 11 detected as measured values Mw and, in the case of defined deviations, as function signal Fs displayed.
  • the measured values Mw resulting from the torsional vibration signals Ds are in Fig. 6 shown.
  • the vibration line 19 gives a functional Vibration curve with the line sections 20 and 21 again. Line section 20 results when the switching elements 15 operate with a reduced stroke; the line segment 21 when the switching element works with maximum stroke.
  • the torsional vibration peaks 22 and 23 of line segments 20 and 21 are substantially uniform Course on, which means that the switching elements 15 according to the design, ie are duly effective.
  • the vibration line 19 ' shows both in Line section 20 'as in line section 21' from the normal Torsional vibration peaks 22 'and 23' differing torsional vibration peaks 24 and 25, The latter go to malfunctions of one or more switching elements 15 back.
  • the torsional vibration signals or measured values Mw are determined by means of a Hall sensor 26 removed, which is assigned to the intake camshaft 11. Are suitable for this also induction sensors, optical sensors et cetera.
  • An electronic evaluation unit 27 determines the speed n of the internal combustion engine, Switching state SchzVsZ3 of the valve lift control of cylinder bank 3, measured values MwZ3 of Intake camshaft 11 of cylinder bank 3, switching state SchzVsZ4 of the valve lift circuit of the cylinder bank 4 and measured values MwZ4 of the intake camshaft 11 'of the cylinder bank 4 fed. This data is processed in the evaluation electronics 27. If at the Switching elements 15 malfunctions will occur on a display device 28 of the mapped as function signal Fs.
  • FIG. 4 shows a diagram in which the function signal Fs in a Evaluation electronics 29 by the parameters switching state SchzNv des Camshaft adjuster 18, switching state SchVs valve lift, measured values Mw der Inlet camshaft 11 and oil temperature Töl of the internal combustion engine 1 is formed.
  • the switching state SchzNv of the camshaft adjuster 18 on a first Solenoid valve 30 removed; the switching state SchzVs of the valve lift control on one second solenoid valve 31.
  • the measured values Mw of the intake camshaft 18 are taken by the Hall sender 26, which interacts with the intake camshaft 11.
  • the evaluation electronics 29 the measured values Mw are compared with nominal measured values MwSo and form the basis of the function signal Fs.
  • the intake camshafts 11 and 11 'of the cylinder banks 3 and 4 for Formation of the function signal Fs used d. H. are measured values MwZ3 of the cylinder bank 3 and the measured values MwZ4 cylinder bank 4, the switching elements 15 work identically given framework.
  • evaluation electronics 31 In the event of deviations, evaluation electronics 31 generate this Function signal Fs.For this purpose, the following parameters are fed to the evaluation electronics 31 Switching status SchzNvZ3 and SchzNvZ4 of the camshaft adjuster 18 of the cylinder banks 3 and 4, switching state SchzVsZ3 and SchzVsZ4 of the valve lift circuits of the cylinder banks 3 and 4, measured values MwZ3 and MwZ4 of the intake camshafts 11, 11 'of the cylinder banks 3 and 4 and oil temperature Töl of the internal combustion engine 1.
