Definitions

  • the invention relates to an internal combustion engine with gas exchange valves according to the preamble of claim 1.
  • the object of the invention is to provide a generic internal combustion engine in which the energy consumption is reduced by the current applied to the electromagnets.
  • the current switching element is also designed as a semiconductor, specifically as a thyristor.
  • the thyristor can be opened by a control command, but can only be switched into its blocking state if the current flowing through the thyristor is briefly drawn off, so that the thyristor is extinguished.
  • the invention makes use of the knowledge that a transistor gate can withstand a much higher current than the current which it can switch in continuous operation without damage when subjected to a short-term load.
  • the inrush current for the electromagnetic consumer is supplied via the thyristor, but for switching off it is necessary for a few milliseconds to clear the thyristor the entire current is taken over by the transistor, which can cope with this brief surge.
  • the subsequent clocking at a current that is only about 10 to 20% of the inrush current can be done solely via the transistor, which is thereby dimensioned lower.
  • the transistor's collector-emitter saturation voltage is usually lower than the thyristor, such an increase in the resistance of the thyristor branch is not absolutely necessary.
  • an ohmic resistor is provided for safety, its resistance value can be on the order of ⁇ 1 ohm.
  • the transistor 18 can only withstand a current which corresponds approximately to the holding current (taking into account a safety tolerance), but is not destroyed by a short-term, much stronger peak current. Accordingly, a relatively inexpensive type can be used as transistor 18, which would not be able to control the entire inrush current by its design.
  • the current through thyristor 34 has dropped to a value which corresponds approximately to the holding current.
  • the base 24 of the transistor 18 is now supplied with a signal, shown in FIG. 4b, which opens the collector-emitter path of the transistor 18 and thus enables a current to flow through the electromagnetic consumer 14.
  • transistor 18 opens at time T3 the current flows through transistor 18, thyristor 34 is de-energized and thus changes to its blocking state. This now also results in a holding current I halt , the magnitude of which is formed by the pulse duty factor, similar to the illustration in FIG. 3c.
