Abstract

Eine Ansteuerschaltung zur Ansteuerung von Magnetventilen für die Kraftstoffzumessung in einer Brennkraftmaschine (Bänke I und II) weist erfindungsgemäß eine Nachladeschaltung (1) auf, die eine Drosselspule (110) in Reihe mit einer Diode (112) und einem Speicherkondensator (145) sowie einen parallel zur Reihenschaltung aus Diode (112) mit dem Speicherkondensator (145) geschalteten FET-Leistungstransistor (113) aufweist. Die Magnetventile der einzelnen Bänke (I und II) werden ausschließlich mit einer von der Nachladeschaltung (1) erzeugten, vorstabilisierten Spannung angesteuert, die einen weiten Bereich umfassen kann, die Batteriespannung (UBAT) unter- oder überschreiten kann, so dass die aus bisherigen Schaltungen bekannte HS- und Boosterschalter in einem einzigen Schalter realisiert werden können (Figur 2).

According to the invention, a control circuit for controlling solenoid valves for fuel metering in an internal combustion engine (banks I and II) has a recharging circuit (1) which has a choke coil (110) in series with a diode (112) and a storage capacitor (145) and a parallel circuit for the series connection of diode (112) with the storage capacitor (145) connected FET power transistor (113). The solenoid valves of the individual banks (I and II) are controlled exclusively with a pre-stabilized voltage generated by the recharging circuit (1), which can span a wide range, the battery voltage (U BAT ) can fall below or exceed, so that from previous ones Circuits known HS and booster switches can be realized in a single switch (Figure 2).
