Abstract

Erkennt die Steuerungseinrichtung nach einem Stoppen der Brennkraftmaschine, ohne dass dabei die Zündung ausgeschaltet wurde, eine erneute Drehung der Kurbelwelle, so wird die Kraftstoffeinspritzung freigegeben, wenn zugleich die Batteriespannung (UB) um einen bestimmten Wert eingebrochen ist oder die Fahrzeuggeschwindigkeit (V) Null ist. Ist keine der beiden Bedingungen erfüllt, so wird die Kraftstoffeinspritzung solange verboten, bis z.B. mit Hilfe einer Drehzahlüberwachung sichergestellt ist, dass die Drehung der Kurbelwelle vom Starter bedingt ist.

Figure 00000001
If the control device recognizes a renewed rotation of the crankshaft after the internal combustion engine has stopped, without the ignition being switched off, the fuel injection is released if at the same time the battery voltage (UB) has fallen by a certain value or the vehicle speed (V) is zero , If neither of the two conditions is fulfilled, the fuel injection is prohibited until, for example, it is ensured by means of a rotational speed monitoring that the rotation of the crankshaft is conditioned by the starter.
