Abstract

Es werden eine Vorrichtung und ein Verfahren zur Ansteuerung wenigstens eines elektromagnetischen Verbrauchers (100), insbesondere eines Magnetventils zur Steuerung der Einspritzung von Kraftstoff in eine Brennkraftmaschine beschrieben. Die Einspritzung ist in wenigstens eine erste und eine zweite Teileinspritzungen aufgeteilt. Die in einem Speichermittel (145) gespeicherte Ladung wird zu Beginn der Ansteuerung (1) in den Verbraucher (100) umgeladen. In dem Speichermittel (145) verbleibt bei der ersten Teileinspritzung eine Teilladung.
