Definitions

  • the invention relates to a method for controlling an electromagnetically controllable intake valve with the features of the preamble of claim 1.
  • the invention also relates to a computer program for executing the method.
  • a high-pressure pump with an integrated inlet valve via which fuel can be fed into a pump work chamber of the high-pressure pump.
  • the inlet valve can be controlled in such a way that it is possible to meter the fuel in order to fill the pump working chamber completely or partially.
  • the intake valve is actuated by means of a magnetic coil, which is energized to open the intake valve. The activation preferably takes place as a function of the movement of a pump piston of the high-pressure pump, the inlet valve also preferably being opened when the pump piston reaches its top dead center position.
  • the electromagnetic actuator is initially energized independently of the position of the pump piston according to a predetermined energization strategy, in such a way that the delivery rate of the high-pressure pump is not affected.
  • the method thus ensures the delivery of fuel from the start of the internal combustion engine from the first delivery stroke of the high-pressure fuel pump.
  • the specified energization strategy can provide for an energization at intervals or a permanent energization, with a volume regulation with permanent energization not being possible.
  • the power supply at intervals also has the advantage that the power loss can be kept low compared to continuous power supply.
  • control device for a high-pressure pump with a pump chamber and a reciprocating pump piston is also known.
  • the control device includes valve opening control means for performing valve opening control in which energization of a coil of an electromagnetic actuator is stopped so that a regulator valve for filling the pump chamber is opened.
  • Intake valves of the type mentioned above are sensitive to particles contained in the fuel. As a rule, therefore, a strainer is installed upstream of the intake valve in order to retain such particles. At low outside temperatures or low fuel temperatures, paraffin precipitations can occur in the fuel, which can cause the strainer to become clogged. As a result, there may be rail pressure deviations and the internal combustion engine may fail to start or fail. At best, an emergency driving mode is activated, but this only permits limited engine performance.
  • the present invention is based on the object of specifying a method for controlling an electromagnetically controllable intake valve that provides reliable quantity control even at low outside or fuel temperatures allows. In this way, rail pressure deviations and the associated failures of the internal combustion engine are to be avoided.
  • a solenoid coil is energized to close the intake valve.
  • the inlet valve is designed as a normally open valve.
  • the current is supplied as a function of the piston stroke of a pump piston of the high-pressure fuel pump.
  • a power loss that is used to heat the fuel is introduced via the energization of the magnetic coil.
  • the heating of the fuel reduces the risk of paraffin precipitation and thus the risk of a filter upstream of the intake valve becoming clogged. Because depending on the operating point, part of the fuel quantity previously fed to the high-pressure element chamber via the inlet valve is pushed out again, so that fuel heated in this way reaches the inlet area and thus in front of the strainer. The heated fuel that is pushed out prevents the sieve from clogging or clogging due to paraffin precipitation, so that reliable volume control via the inlet valve is ensured even at low outside temperatures. At the same time, this reduces the risk of the internal combustion engine, which is supplied with fuel by means of the high-pressure fuel pump, failing to start or failing.
  • the power loss for heating the fuel is introduced in a targeted manner by varying an energization strategy that serves to control the intake valve.
  • the opening and closing behavior of the intake valve preferably remains unaffected by this in order to continue to enable precise volume control.
  • An electromagnetically controllable inlet valve is usually controlled once during a delivery cycle of a high-pressure fuel pump.
  • the current supply parameters are generally selected in such a way that the intake valve closes reliably with the smallest possible use of energy.
  • a typical flow profile with the associated stroke H of the pump piston over time t is shown in FIG 1 shown. That Flow profile A has a short pull-in current phase a for closing the inlet valve and a subsequent holding current phase b, in which the current level is reduced.
  • the holding current phase b is followed by a phase c, in which the current flow is interrupted or the inlet valve is open.
  • TDC top dead center
  • an energization profile is selected which requires an increased use of energy to introduce the power loss.
  • the duration of the energization can be extended and/or the current level can be increased.
  • the time intervals between successive energization phases can be shortened, so that the electromagnetically controllable inlet valve is controlled more than once during a delivery cycle of the high-pressure fuel pump.
  • the energization of the magnet coil is preferably continued after the closing of the inlet valve at an unchanged high current level or at a reduced current level over a specific period of time.
  • the high current level may correspond to the current level for closing the intake valve (pick-up current level) by, for example, not switching to a reduced current level (holding current level) after the intake valve has closed.
  • the current level can be reduced after closing, for example by switching to holding current.
  • the continuation of the energization at the same or reduced current level takes place within a delivery cycle of the high-pressure fuel pump. This means that the energization phase is interrupted at least once within a delivery cycle in order to enable volume control via the inlet valve.
  • the energization of the magnet coil is preferably terminated before the pump piston of the high-pressure fuel pump has reached a bottom dead center position.
  • the intake valve for volume control remains open throughout the intake phase.
  • the energization of the magnetic coil can be extended beyond the bottom dead center of the pump piston if a low delivery rate is required.
  • the energization of the magnet coil is continued at intervals after the closing of the intake valve. This means that during a pumping cycle of the high-pressure fuel pump, several consecutive current surges are set.
  • the current supply duration of the individual current pulses is chosen to be sufficiently short, so that the inlet valve is not actuated, in particular during the delivery stroke of the pump piston.
  • the duration of the energization must be limited, since the closing forces from the hydraulics increase with increasing speed.
  • the duration of the energization is preferably selected to be so short that closing is prevented in all speed ranges. Alternatively, the duration of the current can be varied with the speed.
  • the current level and/or the duration of current application is/are consequently varied as a function of the rotational speed.
  • the magnet coil is energized at a holding current level or a current level below that before the intake valve closes. Closing can then be started from the holding current level or the current level below it by increasing the current level to an inrush current level. In this way, the energization duration can be maximized without the risk of the intake valve closing unintentionally.
  • the current level is briefly increased. In order to enable safe closing across all speed ranges, the current level can be briefly reduced before raising. In this way, account is taken of the increasing hydraulic forces as the speed increases.
  • the current level be varied with the aid of a boost function.
  • the boost function enables voltages that are above the normal battery voltage, so that a special fast switching between different current levels and a particularly fast start and/or end of an energization phase are possible. In addition, higher power losses can be realized.
  • the method according to the invention is preferably carried out for a limited period of time, in particular when there is a risk of a screen upstream of the inlet valve jamming.
  • the method is therefore carried out when the temperature falls below a predefined temperature threshold, during a cold start and/or when a predefined fuel viscosity is exceeded.
  • the temperature and/or the viscosity of the fuel are therefore preferably still monitored.
  • the method is advantageously carried out in accordance with a program code of a computer program running on a control device.
  • the program code is stored in the control unit or on a separate storage medium.
  • Measurement data can also be evaluated in the control unit, which allow conclusions to be drawn about the temperature and/or viscosity of the fuel, in order to automatically start the execution of the method if the value falls below or exceeds a predetermined limit value.
  • a computer program with a program code is therefore also proposed, which is stored in a control unit or on a separate storage medium.
  • energization profile A shown is characterized by a comparatively short energization duration, which consists of energization phases a and b.
  • the inlet valve is only energized to close once per delivery cycle, shortly before the pump piston reaches top dead center (TDC).
  • the current profile B differs from the known current profile A 1 because the duration of the current is extended. In addition, the current supply is continued at a consistently high level. In this way, a power loss is introduced that can be used to heat the fuel.
  • the current flow profile D is characterized by several consecutive short current surges or current flow intervals, which together also lead to an increase in the duration of the current flow.
