Definitions

  • the invention relates to a method and a valve control for driving a gas exchange valve for adjusting the power of an internal combustion engine by opening and closing the gas exchange valve, wherein the opening and / or closing of the gas exchange valve in response to a delay time when opening and / or closing the gas exchange valve.
  • JP-A-09329009 a method is already known in which detects the opening or closing position of a gas exchange valve via a stroke sensor.
  • a controller calculates the time difference that elapses between the drive signal and the actual attainment of the desired valve lift position. This measured time difference flows as a correction factor in the valve control.
  • the object is achieved by a method according to claim 1 and by a valve control according to claim 11.
  • the setting of the power of an internal combustion engine by opening and closing a gas exchange valve, wherein the opening and / or closing of the gas exchange valve in response to a delay time when opening and / or closing the gas exchange valve takes place, and wherein the gas exchange valve for determining the delay time for a predetermined Verstellzeit long adjusted and the opening and / or closing of the gas exchange valve is detected.
  • a signal for opening the gas exchange valve in response to an opening delay time between the beginning of the signal to open the gas exchange valve and the opening of the gas exchange valve is formed and the signal for opening the gas exchange valve for the predetermined adjustment time long output.
  • a signal for closing the gas exchange valve in response to a closing delay time between the beginning of the signal to close the gas exchange valve and the closing of the gas exchange valve formed and the signal for closing the gas exchange valve for the predetermined Verstellzeit long spent.
  • the Verstellzeit is extended if no opening and / or closing of the gas exchange valve is detected.
  • the adjustment time is extended until an opening and / or closing of the gas exchange valve is detected.
  • the opening delay time and / or the closing delay time is determined as a function of the adjustment time when opening and / or closing of the gas exchange valve is detected.
  • the opening delay time and / or the closing delay time is set equal to the adjustment time when opening and / or closing of the gas exchange valve is detected.
  • the opening delay time and / or the closing delay time for the gas exchange valve is determined independently of the opening delay time and / or the closing delay time of other gas exchange valves of the internal combustion engine.
  • the opening delay time and / or the closing delay time for the gas exchange valve between operating phases of the internal combustion engine is determined.
  • the gas exchange valve for determining the opening delay time and / or the closing delay time is independent of a necessary by the operation of the internal combustion engine adjustment of Gas exchange valve adjusted.
  • the opening and / or closing of the gas exchange valve by air mass measurement, cylinder-specific air mass measurement, intake manifold pressure and / or combustion chamber pressure measurement is detected.
  • valve 1 shows a valve control 10 for controlling an inflow valve 3 and an outflow valve 4 for setting a gas exchange valve 1 of an internal combustion engine.
  • the gas exchange valve 1 is arranged on a cylinder head 5.
  • an opening 8 is opened or closed and thus set a mass air flow ⁇ i through the opening 8 in a cylinder of the internal combustion engine.
  • a pump 6 for pumping hydraulic fluid.
  • the inflow valve 3 and the outflow valve 4 of the inflow and outflow of hydraulic fluid is controlled in a hydraulic actuator 2 and thus the gas exchange valve 1 moves. If the inflow valve 3 is open and the outflow valve 4 is closed, then hydraulic fluid flows into the hydraulic actuator 2 in such a way that the valve moves in the direction z.
  • the inflow valve 3 is closed and the outflow valve 4 is opened, hydraulic fluid flows out in this way the hydraulic actuator 2, that the gas exchange valve 1 moves in the direction -z.
  • a reservoir 7 for hydraulic fluid is provided for hydraulic fluid.
  • the inflow valve 3 and the outflow valve 4 are controlled by the valve controller 10 by signals s3 and s4.
  • the valve controller 10 is connected to a structure-borne sound sensor, airborne sound sensor, air mass sensor, intake manifold pressure sensor, cylinder-specific air mass sensors, intake manifold pressure sensors and / or combustion chamber pressure sensors.
  • FIG. 2 shows a flowchart for determining the opening delay time of the gas exchange valve 1, which is implemented on the valve controller 10 in an exemplary embodiment.
  • reference numeral 20 designate the beginning of the process and reference numeral 32 the end of the process.
  • a query 21 follows whether so-called thrust exists. Under thrust is to be understood that the kinetic energy of a vehicle that is drivable with the internal combustion engine, the internal combustion engine moves without fuel is burned in the engine. If there is no thrust, the program is ended. If, on the other hand, there is thrust, an initialization step 22 follows. In the initialization step 22, it is determined for which ith gas exchange valve of the internal combustion engine the opening delay time is to be determined.
  • the initialization step 22 is followed by another query 23.
  • Using the query 23 is queried whether thrust is present and whether overrun operation (eg advantageous with closed gas exchange valves) is allowed. If there is either no thrust or if overrun is not permitted, the program is terminated. If, on the other hand, thrust is present and the overrun operation is permissible, a query 24 follows as to whether the air mass flow ⁇ i through the opening 8 is greater than zero. Is the air mass flow ⁇ i If the air mass flow ⁇ i through the opening 8, on the other hand, is not greater than zero, then a step follows.
  • the gas exchange valve is adjusted an adjustment time T AN (i) long.
  • the outflow valve 4 is first closed by output of the signal s4, as z. B. in Fig. 3 is shown. Thereafter, the inflow valve 3 is opened by the signal s3, the adjustment time T AN (i) long, as shown in FIG. 4. In FIGS. 3 and 4, the signals s4 and s3 are shown over the time t. After closing the inflow valve 3, the outflow valve 4 is opened again.
  • Step 25 is followed by a query 26 corresponding to query 24. That is, it follows the query whether the air mass flow ⁇ i through the opening 8 is greater than zero. If the air mass flow ⁇ i through the opening 8 is greater than zero, the value x is reduced by a value n ⁇ ⁇ in a step 27. n is a numerical value, eg 3, and ⁇ is a time duration. Step 27 is followed by query 23.
  • a step 28 follows, in which the adjustment time T AN (i) is increased by a value ⁇ .
  • the gas exchange valve is adjusted the Verstellzeit T AN (i) long in the manner as described with respect to step 25.
  • the step 28 is followed by a query 29 corresponding to the queries 24 and 26. That is, it follows the query whether the air mass flow ⁇ i through the opening 8 is greater than zero. If the air mass flow ⁇ i through the opening 8 is not greater than zero, then followed by a query 30 whether thrust exists, and whether the overrun operation is allowed. In this case, query 30 corresponds to query 23. If there is no overrun operation (more) or if pusher operation is not (anymore) permissible, the program is terminated. If, on the other hand, there is thrust, and if the overrun operation is permissible, step 28 follows again.
  • step 31 follows.
  • the opening delay time equals the current adjustment time T AN (i) and then the adjustment time T AN (i ) is set to its initialization value (as in initialization step 22).
  • the value i is increased by 1. If this new value i is greater than the number of gas exchange valves for which the method described above is to be carried out, then i is set equal to 1.
  • Step 31 is followed by query 23.
  • the flowchart of FIG. 2 is also applicable in an analogous manner for the determination of the closing delay time of the gas exchange valve 1.
  • the gas exchange valve is closed for an adjustment time T AN (i) from the opened state.
  • T AN the starting state of the inflow valve 3 and the closed state of the outflow valve 4 are assumed for a defined time.
  • the inflow valve 3 is closed, and then the outflow valve 4 is opened for an adjustment time T AN (i).
  • the queries 26 and 29 are to be replaced by the query as to whether ⁇ equals zero.
  • FIG. 5 shows the position z of the gas exchange valve 1 over the time t in response to the signals s4 and s3 in accordance with FIG. 3 and FIG. 4.
  • FIG. 6 shows FIG the air mass flow ⁇ i through the opening 8 in Fig. 1.
  • the mass air flow ⁇ i through the opening 8 of a single Gas exchange valve 1 is difficult to measure. It is easier to measure the total air mass flow ⁇ by an air supply for several gas exchange valves.
  • Such an air mass flow ⁇ is shown by way of example in FIG. 7, wherein the air mass flow ⁇ over the
  • Time t is applied. Due to the distance between gas exchange valve 1 and a sensor for measuring the total air mass flow in the effect of opening the gas exchange valve 1 in the total air mass flow in ⁇ delayed by a dead time. By evaluating the total air mass flow ⁇ thus the opening of the gas exchange valve 1 can be detected. The evaluation can z. B. carried out so that the total air mass flow ⁇ in a time window in which a reaction in the total air mass flow ⁇ due to the opening of the gas exchange valve 1 is expected to be monitored. Furthermore, it is possible to form the integral of the total mass flow ⁇ or its mean value and to detect an increase in the integral or the mean value when opening the gas exchange valve 1 and thus the air mass flow ⁇ i through the opening 8.
