Definitions

  • the invention is based on a method for controlling an injection valve for an internal combustion engine, the magnetic coil of the injection valve being applied to an operating voltage in such a pulsating manner with the aid of a semiconductor switch that a current sufficient to open the injection valve flows during a first period of time and that this can possibly occur a second time segment dependent on the intended injection duration is connected with a current sufficient to keep the valve open.
  • Injectors for internal combustion engines with a low internal resistance are controlled by a so-called current control.
  • To open the valve wait until the current through the solenoid of the valve has reached a predetermined value. Then the power is turned off and depending on the provided a pulsating voltage.
  • the rate of rise of the current during the first section depends on the level of the operating voltage, in particular on the state of charge and the further load on the vehicle battery. With a low operating voltage, it can take a long time to reach the specified peak value. This dependency is disruptive in electronically controlled fuel injection systems. For example, at low operating voltages, the first time period can be so long that the injection of small amounts of fuel cannot be precisely controlled.
  • the method according to the invention is characterized in that the first time period is ended by switching off when the current has reached a peak value which is dependent on the operating voltage according to a predetermined function.
  • the specified function can depend in particular on the type of the injection valve. Basically, however, the function will be such that the peak current is higher for a higher operating voltage than for a lower operating voltage.
  • An advantageous circuit arrangement for performing the method according to the invention is that the solenoid coil of the injection valve is connected to an output stage and a current measuring resistor, that the current measuring resistor is connected to the input of a first analog / digital converter and the operating voltage source is connected to the output stage and the input of a second analog / Digital converter are connected, that the outputs of the analog / digital converter are connected to inputs of a processor, the output of which is connected to a control input of the output stage, and that the processor is also assigned a memory for the predetermined function.
  • FIG. 1 a shows the course of the voltage on a magnet coil during an injection process
  • FIG. 1 b shows the course of the current through the magnet coil during the same time.
  • a voltage Ub is applied to the magnetic coil, which results in an increase in the current I through the coil.
  • a predetermined peak value Is is reached at time t1, whereupon the voltage is switched off.
  • the coil is short-circuited at the same time via a further transistor, so that the current falls between t1 and t2.
  • a pulsating voltage causes a current that is sufficient to keep the injector open.
  • the current then drops to 0 again, so that the valve is closed.
  • the injection quantity is regulated by changing the time period between t1 and t3 accordingly. With a minimum injection quantity, the current I drops to 0 after switching off at t1.
  • FIG. 1c shows, with a changed time scale, the current increase after switching on at t0 for different operating voltages, namely for an average operating voltage Um, for a minimum operating voltage Umin and for a maximum operating voltage Umax. Points 1, 2, 3 at which the injection valve opens are marked on the individual curves. With the slow current rise caused by the lower operating voltage, the valve opens at a lower current.
  • the voltage is now switched off at different current values which are dependent on the operating voltage.
  • the resulting points 4, 5, 6 on the curves still have a sufficient safety distance from points 1, 2, 3, which were determined for opening the valve.
  • the switch-off time is brought forward from t1 ⁇ to t1 ⁇ .
  • the solenoid coil 11 of an injection valve is connected in series with a current measuring resistor 22 in the output circuit of an output stage 12.
  • the operating voltage Ub is supplied at 13, while the end of the current measuring resistor 22 facing away from the magnet coil 11 is connected to ground potential.
  • Power amplifiers for injection valves are known per se and need not be explained in connection with the present invention.
  • the output 21 of the output stage 12 can be connected either to the operating voltage Ub supplied at 13 or to ground potential.
  • the operating voltage can be applied to the solenoid coil with a pulse supplied at 14, while a pulse supplied at 15 separates the solenoid coil 11 from the operating voltage Ub and a Connected to ground.
  • the operating voltage Ub is fed to a processor 18 via a first analog / digital converter 16 and the voltage drop across the current measuring resistor 22 is fed via a second analog / digital converter 17.
  • a non-volatile memory 19 is assigned to the processor 18, in which the function is stored according to which the peak current Is is to be controlled as a function of the operating voltage Ub.
  • the processor now reads a corresponding value Is from the memory 19 for the value of the operating voltage Ub supplied by the analog / digital converter 16 and compares it with the current value emitted by the analog / digital converter 17. If the value Is is reached, the processor 18 sends a pulse to the input 15 of the output stage, whereupon the latter separates the magnet coil 11 from the operating voltage Ub and switches it to ground, whereupon the current drops, as explained in connection with FIG. 1.
