Abstract

Bei diesem Verfahren wird in einem Betriebsmodus mit vom elektronischen Betriebssteuergerät gesteuerten Direktstarts dem Zylinder bereits während jeder Abschaltphase eine vorgegebene Kraftstoffmenge zugeführt. Beim Wiederstart der Brennkraftmaschine wird bei Direkteinspritzern eine zusätzliche Kraftstoffmenge eingespritzt, wenn die Zeitspanne zwischen Abschaltung und Wiederstart der Brennkraftmaschine eine vorgegebene Schwelle überschreitet.

Figure imgaf001
In this method, a predetermined amount of fuel is already supplied to the cylinder during each shutdown phase in an operating mode controlled by the electronic control unit direct starts. When restarting the internal combustion engine, an additional amount of fuel is injected in direct injectors when the time interval between shutdown and restart of the internal combustion engine exceeds a predetermined threshold.
