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 während der Schnelllöschung mit einer von der Nachladeschaltung (1) erzeugten Spannung abgeschaltet. Zur Minimierung des Einflusses der einen weiten Bereich umfassenden Batteriespannung (UBATT) wird während den Schnelllöschphasen der HS-FET (115 bzw. 116) abgeschaltet.

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 switched off during the quick extinguishing with a voltage generated by the recharging circuit (1). To minimize the influence of the battery voltage (U BATT ), which spans a wide range, the HS-FET (115 or 116) is switched off during the quick- erase phases .
