Abstract

Es wird eine Kraftstoffeinspritzpumpe vorgeschlagen, bei der die zu den Einspritzstellen geförderte Kraftstoff­ fördermenge durch Dosierung der Kraftstoffansaugmenge bestimmt wird. Die Dosierung der Ansaugmengen erfolgt dabei mit Hilfe wenigstens eines Magnetventils (20) das in der Kraftstoffversorgungsleitung zur Kraftstoffeinspritzpum­ pe liegt und mit Hilfe einer synchron zur Drehung der Kraftstoffeinspritzpumpe bewegten Steuerkante (23), die die Verbindung der Kraftstoffversorgungsleitung zum Pumpen­ arbeitsraum (11) in Reihe zum Magnetventil steuert. Die Öffnungszeiten beider Steuerstellen sind jeweils länger als die maximale Zumeßzeit, wobei die Überlappungszeit der beiden Steuerzeiten die Öffnungszeit der Verbindung der Kraftstoffversorgungsleitung zum Pumpenarbeitsraum (11) bestimmt. Die Zumeßzeit wird somit auf der einen Seite durch die Schaltzeit der Drehzahl synchron bewegten Steuer­ kante und andererseits durch einen Schaltvorgang des Magnetventils bestimmt. A fuel injection pump is proposed at which the fuel delivered to the injection points delivery rate by metering the fuel intake amount is determined. The intake quantities are dosed using at least one solenoid valve (20) the fuel supply line to the fuel injection pump pe lies and with the help of a synchronous to the rotation of the Fuel injection pump moving control edge (23), the Connection of the fuel supply line to the pumps Controls the work area (11) in series with the solenoid valve. The Opening times of both tax offices are longer than the maximum metering time, the overlap time of both control times the opening time of the connection of the Fuel supply line to the pump workspace (11) certainly. The metering time is on the one hand through the switching time of the speed synchronously moving control edge and on the other hand by switching the Solenoid valve determined.
